September 2005 1-1

1 Introduction

This Instruction provides installation and service information for the APACS+™ Enhanced Analog Module (EAM) Model 39EAMBAN and its associated I/O termination hardware as listed in Table 6-2.

This Instruction is divided into six major sections as follows:

• Section 1, Introduction - Provides product description and related literature sections

• Section 2, Installation - Describes mechanical and electrical installation.

• Section 3, Maintenance - Consists of preventive maintenance, troubleshooting, assembly replacement procedures, and spare and replacement parts suggestions.

• Section 4, Circuit Description - Gives a brief system description of the EAM.

• Section 5, Accessories and Options - Provides Model Designation, and tables of accessories and options.

• Section 6, Specifications - Consists of mechanical, electrical, and environmental specifications.

1.1 Product Description

The Enhanced Analog Module (EAM) is a plug-in I/O module which is part of the APACS+ series of control, interface and I/O modules. The EAM is capable of communicating with an APACS+ control module (ACM) way of the IOBUS. The EAM processes 16 field I/O signals. Figure 1-1 shows the EAM and its associated assemblies and cables.

The EAM Termination Strip and EAM Marshalled Termination Assembly each provide channel-to-channel and channel-to-ground isolated terminations for 16 channels of I/O. Each EAM channel can be separately configured using the 4-mation™ configuration software to be one of the following channel types:

• Analog Input/Output • Frequency Input • Totalizer Input • Discrete Input/Output

When a controller configuration is downloaded from a computer running 4-mation to a control module, the EAM portion of the configuration is automatically copied from the control module to the EAM. The control module retains a copy of the EAM configuration. This permits the on-line removal and replacement of the EAM without the need for reconfiguration.

EAM diagnostics can identify field and board level problems. All errors detected by the diagnostics are reported to the controller which maintains a current error log that can be accessed by 4-mation. EAM status is shown by “OK” and “ACTIVE” LED indicators located on the bezel.

Introduction SD39EAM-1r4

1-2 September 2005

The APACS+ architecture provides for rack-to-rack redundancy, where the redundant rack completely duplicates the control and I/O modules of the primary rack. Both racks share common I/O terminations at the Marshalled Termination Assembly via Interconnect I/O Cables.

2 Installation

This section describes installation of the EAM and its associated assemblies. Review the steps in the following section before continuing with EAM installation.

2.1 Preliminary Considerations and Preparation

Figure 2-1 shows typical local and marshalled I/O wiring. I/O connections between field devices and either local or marshalled terminations are wired with user-supplied cable. Typical cable has a jacket and two insulated, twisted-pair conductors with shield. This cabling is referred to as I/O cable.

When marshalled termination is employed, an Interconnect I/O Cable Assembly connects the EAM Marshalled Termination Assembly to the MODULRAC and EAM. Interconnect I/O Cable Assembly part numbers and their standard lengths are presented in section 5. An Interconnect I/O Cable length must be determined before proceeding with the installation of hardware assemblies.

1. Install the MODULRAC and the Local Termination Panel (for local termination only) in the cabinet where EAMs are to be installed. EAMs should not be installed in the MODULRAC at this time; however, the MODULRAC slot numbers for EAM installation should be known.

2. If local I/O termination is employed, tag all I/O cables and route them into the cabinet. They should be ready for cable end preparation and connection to the EAM Termination Strips.

3. If remote termination is employed, tag all I/O cables and route them into the marshalling cabinet. They should be ready for cable end preparation and connection to the EAM Marshalled Termination Assemblies.

Also, route the EAM Interconnect I/O Cable (or Unterminated I/O Cable) between the marshalling cabinet and the cabinet containing the MODULRAC. See Figure 1-1; J1 will be installed in the MODULRAC and P2 will connect to the EAM Marshalled Termination Assembly in the marshalling cabinet.

PN 16190-1


2-4 September 2005

2.3 Environmental Considerations

Many industrial environments create severe operating conditions. The conditions at each EAM location must be within the specifications stated in section 6.

CAUTION

Exceeding the specified operating temperature limits can adversely affect performance and may cause damage. Air temperature should be periodically checked to ensure that this specification is not being exceeded.

To ensure reliable data communications, it would be prudent to locate APACS modules (enclosures) as far as possible from sources of interference such as high current electrical equipment which emit strong electromagnetic fields and switching transients.

Industrial environments often contain particulate, liquid, and gaseous contaminants. Particulate matter, usually dust and dirt, is abrasive and can cause intermittent contact in connectors associated with circuit assemblies. A layer of dust on circuit boards will interfere with semiconductor heat dissipation. Liquid and gaseous contaminants can have a corrosive effect on metal, rubber, plastic and circuit board components. Extended exposure to this environment may result in equipment malfunction.

To reduce contaminant related equipment malfunctions:

4. Identify contaminants and implement methods to reduce their presence.

2. When cleaning equipment and surrounding area, especially the floor, either vacuum away all dust and dirt or use a dampened rag or mop.

3. Clean or replace all air conditioning filters, room air filters, and equipment filters regularly. Inform personnel with access to APACS modules of the need for area cleanliness.

2.4 Equipment Delivery and Handling

The following subsections provide information of interest to shipping, receiving, and warehouse personnel.


September 2005 2-5

2.4.1 Predelivery Test

An EAM that will be installed by the user is fully tested and inspected to ensure proper operation. If the EAM is ordered factory installed in a MODULPAC or other enclosure, the EAM is tested as part of the APACS system and inspected to ensure proper operation.

2.4.2 Factory Shipment

EAMs to be installed by the user are placed in static shielding bags and packaged for shipment. Accessories are packaged separately.

If the EAM is ordered factory installed in a MODULPAC or other enclosure, the enclosure is bolted to a pallet and wrapped for protection during shipment.

2.4.3 Receipt of Shipment

All cartons should be inspected at the time of their delivery for possible external damage. Any visible damage should be immediately recorded on the carrier’s copy of the delivery slip.

Each carton should be carefully unpacked and its contents checked against the enclosed packing list. At the same time, each item should be inspected for hidden damage that may or may not have been accompanied by exterior carton damage.

If it is found that some items have been damaged or are missing, notify Siemens immediately and provide full details. In addition, damages must be reported to the carrier with a request for their on-site inspection of the damaged item and its shipping carton.

2.4.4 Return of Equipment within North America

US Customers:

• Call the Repair Order PAS Inside Sales/Order Management Group at (215) 646-7400, ext 4RMA (4762) weekdays between 8:00 a.m. and 4:45 p.m. eastern time to obtain an RMA number. Mark the RMA number prominently on the outside of the shipment.

• When calling for an RMA number, provide the reason for the return. If returning equipment for repair, a detailed description of failure symptoms and system behavior will be requested. Supply a purchase order number for repairs. Follow the TSC specialist's recommendation for battery connection, if applicable.

• If applicable, you must supply a Material Safety Data Sheet (MSDS) with each item being returned if it was stored or used in a location where hazardous materials were present.


2-6 September 2005

• Package items to be returned in their original shipping containers. Otherwise, package it for safe shipment or contact the factory for shipping recommendations. A module must be placed inside a static shielding bag to protect it from electrostatic discharge.

Canadian customers:

2.4.5 Return of Equipment outside North America

Contact your Siemens Representative.

2.4.6 Equipment Handling

The EAM is completely enclosed and may be safely handled without undertaking special ESD handling procedures provided the bezel compartment door is closed and secured. DO NOT touch the connector pins on the back of the module. Handle the module carefully and do not subject it to excessive shock or vibration.

CAUTION

Use a grounded wrist strap to provide ESD protection whenever the bezel door is opened.

2.4.7 Equipment Storage

The storage temperature and humidity parameters of section 6 must be met for storage of an EAM.

2.5 EAM Termination Strip Installation

A EAM Termination Strip is to be installed at the MODULRAC slot location of each EAM when local I/O termination is employed. As shown in Figure 2-2, a Local Termination Panel must be installed. Refer to Figure 2-2 and the following installation procedure:

1. Consult user documentation and note the slot locations assigned to each EAM in each MODULRAC.

2. Note the following on a MODULRAC and Termination Strip:

• On a MODULRAC, locate and identify the extruded spacer to which the lower edge of the backplane is mounted. The bottom of the extruded spacer is grooved. The top edge of a Termination Strip will rest in this groove.


September 2005 2-7

• Identify ten alignment pins located below the MODULRAC frame that span the width of the MODULRAC panel. One of these pins will engage a hole located on the Termination Strip above the MOORE logo. The left-most pin corresponds to MODULRAC slot #1.

• The Termination Strip’s captive mounting screws can be seen projecting from the bottom of the plastic extrusion panel.

2-12 September 2005

2. Mount the Marshalling Utility Panel, Utility Panel or user fabricated panel in a MODULPAC marshalling cabinet or user supplied cabinet. Refer to Instruction SD39MODULPAC-1 for installation of the Utility Panel or Marshalling Utility Panel.

3. Retrieve the EAM Marshalled Termination Assembly to be mounted including a supplied bag of EAM labels (PN 14205-665) and a Cable Keying Kit (PN 16056-435). Set aside the Cable Keying Kit.

1) Consult user documentation and note the MODULRAC address number (1 to 16) and slot number (1 to 10) assigned to the EAM, and if applicable the redundant EAM that will be connected to this EAM Marshalled Termination Assembly. For rack-to-rack redundant EAMs connected to a MODULNET, the MODULNET node address must also be noted for each MODULRAC.

2) Retrieve an EAM label and record the noted MODULRAC and slot numbers on the label (see Figure 1-1) If MODULNET redundancy is applicable, record the appropriate node addresses on both EAM labels. Save the remaining labels for use in section 2.6.3.

4. Refer to Figure 1-1 and attach the EAM label adjacent to connector J1 as illustrated in the figure. If applicable, attach the redundant EAM label adjacent to J2. Ensure that J1 and J2 are factory keyed according to the pattern shown in Figure 2-3. The user then keys the connector on the mating Interconnect I/O Cable, in section 2.6.3. This prevents connection to the Termination Assembly of an Interconnect I/O Cable from another type of APACS I/O module (e.g. SDM or VIM).

5. Refer to Figure 2-5 to mount the EAM Marshalled Termination Assembly to a DIN rail.

2.6.2 Optional (Flat Surface) Marshalled Termination Assembly Installation

The removal of the DIN rail mounting feet from the EAM Marshalled Termination Assembly (MTA), in conjunction with the installation of four Mounting Ears (accessory item), permits the MTA to be flat mounted to a panel or bulkhead. Four P/N 16056-562 (single piece) Mounting Ears are required per MTA.

Refer to Figure 2-6 and the following installation procedure:

1. At one end of the MTA, remove the three end cap securing screws from the card holder End Cap. Remove and set aside the End Cap.

2.6.3 Cable Installation

An Interconnect I/O Cable (Figure 2-7) is used to connect each EAM to an EAM Marshalled Termination Assembly when remote I/O termination is employed. Install cable-to-module connector J1 at the MODULRAC slot location of an EAM. It is assumed that as part of the site preparation procedure all tagged Interconnect I/O Cables have been routed and pulled into their respective cabinets and are ready for connection. EAM Marshalled Termination Assemblies should already be installed in the marshalling cabinet (see section 2.6.1) and be ready for cable connection. An Unterminated I/O Cable is installed similarly at the MODULRAC; however, terminations in the marshalling cabinet are user supplied.

1. Note the following on the cable’s J1 connector.

• The lower face of the molded connector has a “pin mounting hole” located above a captive mounting screw. This hole engages one of the MODULRAC Panel’s ten alignment pins.

• The top edge of J1 will rest in the groove of the backplane’s extruded spacer as illustrated by a detail in Figure 2-2.

2. Consult user documentation and note the MODULNET node address (if any), MODULRAC address number (1 to 16) and slot number (1 to 10) assigned to the EAM. J1 will be mounted at this location.


September 2005 2-15

3. Install J1 at its assigned location as follows:

1) Angle the top edge of J1 toward the backplane’s extruded spacer and insert it in the spacer’s groove.

2) Slide J1 in the groove until it is aligned vertically and horizontally with the correct slot # and pin.

3) Carefully lower J1 and engage the alignment pin with its pin mounting hole. Firmly push down to seat J1 on the pin. When J1 is properly seated, the pin will be flush with or project slightly above J1's face.

4) Tighten J1's captive mounting screw, which is automatically aligned with its panel mounting hole.

5) Get two labels from the bag of EAM labels. Record on each label the appropriate numbers noted in the above step 2 (see Figure 1-1). Attach one label to J1 as shown in Figure 1-1.

6) At the P2 end of the cable, attach a second label; see Figure 1-1.

4. Key cable connector P2.

1) Get the PN 16056-435 Cable Keying Kit set aside in step 3 of section 2.6.1.

2) Refer to Figure 2-7 for the assigned keying pattern and install the pins in accordance with the supplied Instruction.

5. Connect the free end of the I/O Cable to an I/O termination assembly. Perform either of the following steps 1) or 2) depending upon I/O Cable type.

1). Interconnect I/O Cable Assembly (P2 installed)

Connect P2 (Figure 2-7) to the “A” (J1) connector on the Marshalled Termination Assembly (Figure 1-1). A keying pin projecting from the face of P2 ensures a correct mating. Press P2 firmly onto J1 and torque the securing screw on the top of P2’s connector shell to 50 inch-pounds maximum.

2). Unterminated I/O Cable Assembly (P2 not installed)

Refer to Table 2-3 for color code identification and function of each unterminated wire. Refer to user wiring diagrams to make the proper cable connections to the termination assembly.

6. Redundant EAMs only.

Connect the redundant Interconnect I/O Cable’s P2 connector to “B” (J2) of the Marshalled Termination Assembly as described in the above step 5.

2.7 EAM Installation

Modules are shipped individually packaged in protective, sealed, static shielding bags. Refer to section 2.4 for module handling considerations.

Each MODULRAC slot and each module must be keyed to prevent accidental installation of a module into an incompatible slot, which may impair system performance. Keying is highly recommended; see Figure 2-8.

• Modules are keyed at the factory. The keying pattern is unique to each module type (e.g. ACM, EAM, SDM). See Figure 2-8 for the EAM keying pattern.

• A MODULRAC installed in a cabinet by the factory is keyed at the factory. A user-installed MODULRAC is keyed by the user according to the module type assigned to each slot. This keying pattern complements the module’s keying pattern. Stop plugs are supplied with the MODULRAC.

• When adding a module to a MODULRAC, be sure to key the MODULRAC slot. Section 2.7.1 describes keying a MODULRAC slot. Section 2.7.2 describes installing the module in the MODULRAC.

2.7.1 MODULRAC Mechanical Keying

1. Get the MODULRAC Keying Kit supplied with the MODULRAC.

2. Refer to Figure 2-8 and note the MODULRAC keying pattern. Also, locate the MODULRAC top and bottom rails. Press the stop plugs into the holes identified by the solid dots.

September 2005 2-19

2.7.2 Module Installation

Installation Procedure (Refer to Figure 2-8):

1. Refer to user documentation for the EAM MODULRAC slot number.

2. Remove the EAM from its static shielding bag and ensure that the module is keyed. Also, check the MODULRAC slot to be sure it is keyed. Refer to section 2.7.1 to install keying.

3. Insert the module in the assigned MODULRAC slot. Firmly seat the module in the backplane and termination board connectors. A properly seated module will have the rear of its bezel flush against the MODULRAC’s front rails. A keyed module that is not matched to a slot will not engage the backplane or termination board connectors or seat flush against the MODULRAC’s rails.

4. Pull open the bezel’s pivoting top and bottom handles to expose the slotted captive mounting screws and secure the module to the top and bottom rails. Close the bezel’s handles when finished.

IMPORTANT

Do not use the captive mounting screws to seat the module. Damage to the bezel can result.

2.8 Electrical Installation

The following sections describe I/O cable connections to an EAM Termination Strip or EAM Marshalled Termination Assembly. It is assumed that tagged I/O cables have been pulled into the cabinet and are ready for preparation and connection.

DANGER









2-20 September 2005

2.8.1 I/O Cable Connections

An EAM Termination Strip and an EAM Marshalled Termination Assembly provide for connection of up to 16 configurable input or output channels. Refer to the following for I/O cable connections:

1. Consult user EAM configuration documentation and wiring diagrams for assignments to each channel. Refer to Table 2-1 for terminal identification and connections and Figure 2-9 for wiring examples.

2. Prepare the cable conductors and shield (see Figure 2-10). Refer to Table 6-2 for wire size, stripping, and torque specifications.

3. Refer to Table 2-2 to correlate channel terminal connections and terminal strip numbers.

2.8.2 Unterminated I/O Cable

An Interconnect I/O Cable connects an I/O module to a Marshalled Termination Assembly. If the user is providing a remote termination assembly, an Unterminated Interconnect I/O Cable is required. The Unterminated I/O Cable does not have connector P2 installed. Wires are instead left for the user to terminate. Table 2-3 lists the wire color and identification information needed for termination. Refer to user wiring diagrams to make the proper cable connections to the termination assembly.

2.9 APACS Calibration Verification Requirements - Long Term Drift

The APACS analog I/O is designed to minimize calibration drift and the need for re-calibration over the life of the product. Design improvements include:

• Elimination of adjustable potentiometers • Elimination of adjustable resistors • Use of high quality, low drift components

Calibration is performed through mathematical compensation within the microprocessor program. This allows the use of matched resistors for voltage dividers and minimizes the problem of temperature coefficient matching.

Because the other sources of drift have been minimized, the dominant contributor to analog long term drift for all analog modules is the voltage reference used for the A/D or D/A circuit. Manufacturer data specifies a typical long term drift in terms of the first 1000 hours of operation. Typically, drift for the next 1000 hours will be less. In fact, studies have shown that the I/f noise model is valid for long term drift. This model indicates that the drift will be proportional to the square root of the time period as a limiting factor.

A drift of 20ppm over the first 1000 hours is a typical drift for a high quality reference such as used in all APACS analog modules. Using 30ppm to account for the other secondary drifts, such as precision resistor ratios, indicate it would, on average, take 126 years for a module to drift 0.1% from original calibration due to this mechanism. Drift of 0.05% would on average take 31 years.


September 2005 2-21

Using a more conservative 100ppm drift for 1000 hours as a worst case estimate indicate it would take greater than 11 years to drift 0.1%.

Long term drifts sigificantly greater than typical would be due to flaws inherent to the manufacturing process of the individual components or the module itself. APACS screens out even these unlikely occurrences through multiple additional layers of control. All calibration is done through mathematical compensation as mentioned above. In addition, the range of compenstion is restricted to prevent compensation for inherently defective devices. All APACS modules go through environmental stress screening before functional testing and calibration to precipitate failure of weak components. Finally, all APACS modules go through an elevated temperature burn-in followed by a final functional verification including calibration.

For these reasons, Siemens does not recommend the need for periodic verification of analog caibration more often than once every ten years if the system design can accommodate a 0.1% drift from original calibration. This recommendation is based on the assumption that specified limits for the modules have not been exceeded.

Calibration-related error messages and/or known overstress conditions being applied to analog I/O points could indicate the need for verification before the end of a ten year period.

DANGER








3.1 Tool and Equipment Requirements

The following tools and equipment are necessary for servicing:

• Common electronic servicing hand tools • Digital Multimeter (DMM): Accuracy, ammeter section +/-0.05% of reading

3.2 Visual Inspection

The EAM and its associated assemblies should be subjected to a periodic visual inspection. The frequency of inspection will depend on the severity of the operating environment.

The primary aim of the inspection is to reveal any excessive accumulation of dust, dirt, or other foreign material adhering to the surfaces of transition board and protective covers of an EAM. Accumulation of dirt and dust prevents efficient heat dissipation and may cause module or system failure. An EAM installed in a cabinet complying with the NEMA 12/IP55 specification need not be inspected for cleanliness. Refer to section 3.3 for cleaning instructions.

The status of the EAM is indicated by an LED located on its bezel. Refer to section 3.4 for LED indications.

SD39EAM-1r4 Circuit Description

September 2005 4-1

4 Circuit Description

The Enhanced Analog Module (EAM) is an APACS+ I/O module that is capable of communicating with an APACS+ control module (ACM) by way of the IOBUS. Figure 4-1 is a simplified block diagram of the signal processing portion of an EAM. Figure 4-2 is a block diagram of 1 of the 16 identical input/output channels.

An EAM plugs in to a single MODULRAC or SIXRAC slot. The module’s bottom rear connector mates with either the EAM Termination Strip for local I/O connections or the EAM Interconnect I/O Cable, which in turn connects to an EAM Marshalled Termination Assembly, for remote I/O connections. A Local Termination Panel is needed to mount an EAM Termination Strip when local termination is employed. The Panel is not needed when marshalled (remote) terminations are installed.

The EAM consists of the following elements:

• I/O Channel ASICs (Application Specific Integrated Circuits) - Process input/output signals. • CPU - Provides interfacing to the IOBUS and channel ASICs and control of I/O circuits. • Memory (RAM and EPROM) - Stores module executable code and configuration parameters. • IOBUS Modem - Provides digital data and command conversion needed for communication between

the EAM and control module. • I/O Communications Timing Circuit - Provides data/command and timing conversion needed for

communication between the CPU and 16 channel ASICs. • Redundancy circuit - Provides mode select/control/status signal conversion between the controller

and EAM. • Peripherals circuits - Provides data and command conversion needed for communication between the

CPU and the redundancy circuits, and channel Groups A and B optoisolators. • LED Indicators (on module bezel) - An “ACTIVE” LED indicates that the module is enabled. An

"OK" LED indicates the module status.

4.1 I/O Communications

Serial communication between Group A and B channel I/O ASICs and the CPU occurs via pulse transformers coupled to two (A and B) half-duplex, bi-directional, synchronous party-line data buses. The A and B party-line buses, each of which hosts 8 ASICs, are interfaced to serial multi-protocol ports of the CPU via an I/O communications timing circuit consisting of isolation transformers, dual high-speed line receivers and a programmable logic IC.

The communications format is a simplified HDLC (High-level Data Link Control) protocol. The clock used for I/O communications is the same as the ASIC clock. The ASIC clock is derived from a channel’s power transformer secondary waveform. A transformer is driven by a 368 KHz DC-to-DC converter.

Each channel ASIC produces an I/O value 180 times a second. Messages are sent to and from the ASIC at a rate of 180 Hz. Part of the ASIC’s internal timing is based on receiving a poll message from the CPU at precisely this rate. The I/O Communications Timing interface circuit ensures that messages between the CPU and ASIC are correctly “paced” to accommodate 1440 transmit messages per second (8 ASICs @ 180 Hz) per CPU multi-protocol port. Since each ASIC replies to its own message from the CPU, there are also 1440 receive messages per second per CPU multi-protocol port.

Circuit Description SD39EAM-1r4

4-2 September 2005

Figure 4–1 EAM Block Diagram

4.2 Channel Circuitry

All 16 channels have identical circuitry. As shown in Figure 4-2, the circuitry for a single I/O channel consists of the following principal components:

• An I/O ASIC • An output FET (Field Effect Transistor) • An opto-coupler • A precision 250 ohm current sense resistor • A DC-to-DC power rectifier and filter • A communications pulse transformer


September 2005 4-3

Power is normally supplied to each isolated channel via an isolation power transformer driven by a power chopper DC-to-DC converter circuit. The transformer secondary’s voltage waveform is AC coupled into the ASIC’s clock input in addition to being rectified for isolated 24 Vdc ASIC and I/O power. The 24 Vdc I/O field power is switched through an opto-coupler and applied through a diode to the PWR terminal on a local or remote termination assembly. Additionally, the 24 Vdc is connected by a diode to the O-Sense pin of the ASIC. This pin is used for diagnosing the condition of the 24 Vdc supply and detecting the state of the external opto-coupler.

The ASIC features the following:

• An ADC (Analog-to-Digital Converter) for input signals of 0-5V or 0-20mA • A DAC (Digital-to-Analog Converter) for an output signal of 0-20 mA • Reads voltage or current frequency inputs at frequencies up to 46080 Hz • Contains built-in diagnostics • Designed for bi-directional Manchester encoded serial data over a communications transformer for

ease of isolation • Uses HDLC (Hi-Level Data Link Control) protocol • Synchronous internal digital circuits are clocked by an external clock derived from the power

transformer secondary

Each EAM channel can be separately configured via APACS 4-mation configuration software to be one of the following channel types:

• Analog input (4-20mA, 0-20mA, 1-5V, or 0-5V) • Analog output (4-20mA or 0-20mA) • Frequency input (0-46 kHz) • Totalizer input • Discrete input (sinking or sourcing) • Discrete output (sourcing)

An EAM configuration is downloaded into the module’s memory and a copy of the configuration is stored in the associated control module’s non-volatile memory.

Figure 4–2 Typical EAM Channel

4.2.1 Field Connections

The EAM Termination Strip and EAM Marshalled Termination Assembly each provide isolated termination for 16 channels of I/O. A channel comprises 4 terminals:

• PWR - Field Power Source • VIN - Field Signal (Analog/Discrete Voltage Input) • COM - Field Signal Common (Return) • SHLD - Cable Shield

There are three basic types of field terminal connections: voltage input, current input, and current output.

4.2.1.1 Voltage Inputs

Analog voltage input connections are made to the VIN and COM terminals. The COM connection is completed through the N-Channel FET Q2, which is turned on hard, and the current sense resistor R3.

The voltage signal at VIN is connected by R1 to the V-Sense input of the ASIC, which is an input to an internal ADC and pulse counting and timing circuits. In analog voltage input mode, resistor R1 is internally connected to external capacitor C1 on the C-Alias pin of the ASIC. This forms an anti-alias RC low-pass filter for the ADC.

R1 prevents excessive current into the ASIC when a signal up to 30 Vdc (or a miswiring up to 120 Vac) is applied to the VIN terminal. In addition, in the event of a fault within the ASIC, R1 prevents large currents from being supplied to field wiring.

4.2.1.2 Current Inputs

Current input connections are made to the PWR and COM terminals. For 2-wire (4-20 mA) current inputs, power is supplied through Opto-Coupler Q1 (which is saturated on) to the PWR terminal. The return is through Q2, which is turned on hard, and current sense resistor R3. R3 converts the current to a voltage, which is read by the ASIC at its I-Sense input through resistor R2.

The voltage input to I-Sense is an input to an internal ADC and pulse counting and timing circuits. In analog current input mode, the resistor R2 is internally connected to the external capacitor C1 on the C-Alias pin of the ASIC. This forms an anti-alias RC low-pass filter for the ADC.

4.2.1.3 Current Outputs

Current output connections are made to the PWR and COM terminals. Power is supplied through Opto-Coupler Q1 - which is saturated on - to the PWR terminal. The return is through Q2 and current sense resistor R3. However, in this case, Q2 is not turned on hard. Q2 is controlled by a feedback circuit within the ASIC so that current sensed by R3 and the I-Sense input agrees with the desired output current.

4.3 EAM Redundancy

EAM redundancy is accomplished by rack-to-rack type redundancy through pairs of duplicate racks of I/O and control modules that share a common I/O termination such as the EAM Marshalled Termination Assembly.

The EAM in standby mode is identified by a solid Green "OK" LED and a Black (OFF) ACTIVE LED. If the controller in the active rack detects an error in a module within its rack, it will transfer control to the controller in the redundant rack. The redundant controller will then enable all the I/O modules under its control. A solid Green ACTIVE LED indicates an enabled module.

4.4 EAM Diagnostics

Part of the EAM program includes the execution of diagnostics that can detect the following types of field and hardware errors.

Field Problems

• Open Circuit • Short Circuit • Under-Range • Over-Range


4-6 September 2005

Board Problems

• Backplane Power Failure • Internal Module Overtemperature • RAM Checksum • ROM Checksum • Redundancy Switch-Over

An OK LED and an ACTIVE LED on the module’s bezel provide a local indication of the following module status:

• Module OK • Channel(s) Faulted • Module Faulted • Module Not Configured • IOBUS Communication Fault • Module Active (Redundancy Primary) • Module Inactive (Redundancy Backup)

The OK LED is the principal error annunciator. At initial turn on, the EAM’s CPU uses a common start up routine to perform certain self-diagnostics, such as ROM and RAM tests, and to setup specific board functions. If the common start up routine is successful, the OK LED will be set to a solid green color and the EAM begins to execute common I/O board diagnostics; if not successful, the OK LED will be set to a flashing red color at a 1 second flash rate.

The ACTIVE LED lights to a solid Green if the module is enabled. A redundant EAM in the standby mode will show a solid Green OK and Black (OFF) ACTIVE LEDs.

All errors generated by the diagnostics are reported to the control module (ACM), which maintains a current error log that can be accessed by any APACS+ operator interface or the 4-mation configuration software. The 4-mation software also provides additional diagnostic and status displays.
