CONTROL DOCUMENT


1.0 GENERAL INFORMATION

1.1 THE AutoPILOT LISTING

The AutoPILOT is UL-Listed for use in Class I Division 1, Groups C and D hazardous locations for

United States installations, and C-UL listed for Class I Division 1, Groups C and D hazardous

locations for Canadian installations. It is intrinsically safe when connected according to this control

document. The AutoPILOT has an Operating Temperature Code of T3C. WARNING:

Substitution of components may impair the intrinsic safety of the AutoPILOT.

The listing includes connections for a System Approval and Entity Approval. The AutoPILOTlisting includes the following maximum number and type of electrical connections:

• One Power Input (System Listing)

• Three Host Ports (RS-232 port; System Listing for use with ISCOM 3-0474-004 or 6V

ISCOM 3-0474-016 or 3-0474-025)

• One CHIT Port (Local RS-232 port; System Listing for use with CHIT, or with Entity

Parameters)

1.2 CONCEPT OF ENTITY APPROVAL

The concept of an Entity Approval allows connection of intrinsically-safe apparatus and intrinsically-

safe associated apparatus, including barriers, that have not been specifically approved as a system.

Refer to Article 504 of the National Electrical Code, NFPA 70, for acceptable wiring methods,

sealing methods, and separation of intrinsically-safe and non-intrinsically safe wiring for United

States installations, or Section 18 of the Canadian Electrical Code for wiring, sealing and separationrequirements for Canadian installations.

Under Entity Approval, connection between an intrinsically-safe apparatus and an intrinsically-safe

associated apparatus is limited as follows:

1. The approvedMaximum Open-Circuit Voltage (Voc) of the associated apparatus must be less

than or equal to the Maximum Safe Input Voltage (Vmax) of the intrinsically-safe apparatus.

(Voc Vmax)

2. The approved Maximum Short-Circuit Current (Isc) of the associated apparatus must be lessthan or equal to the Maximum Safe Input Current (Imax) of the intrinsically-safe apparatus.

(Isc Imax)

3. The approved Maximum Allowable Capacitance (Ca) of the associated apparatus must be

greater than or equal to the sum of the Internal Capacitance (Ci) of the intrinsically-safe

apparatus and the Wiring Capacitance (Cw). (Ca Ci + Cw)

4. The approved Maximum Allowable Inductance (La) of the associated apparatus must be

greater than or equal to the sum of the Internal Inductance (Li) of the intrinsically-safe

apparatus and the Wiring Inductance (Lw). (La Li + Lw)

Note

If the wiring parameters (capacitance and inductance) are not known, use the following

parameters:

• Wiring Capacitance of 60 pF per foot

• Wiring Inductance of 0.2 H per foot

A 100-foot cable has a Cw of 6000 pF (0.006 F) and a Lw of 20 H.

When two intrinsically-safe devices are connected and installed in the hazardous location, the same

four entity approval concepts apply. However, they must be applied from both directions: first with

the AutoPILOT as the intrinsically-safe apparatus connected to an intrinsically-safe associated

apparatus (such as a pressure transmitter), then the AutoPILOT as the intrinsically-safe associated

apparatus connected to the intrinsically-safe apparatus (pressure transmitter).

1.3 BARRIER INFORMATION

When the device connected to the AutoPILOT is not an approved intrinsically-safe device for use

in the hazardous location, it must be installed in an non-hazardous area, and an intrinsically-safe

barrier must be wired between the AutoPILOT and the device. The general requirements of the

selected barrier are as follows:

The barrier output must be limited by a resistor such that the output voltage verses current plot

is a straight line between Voc and Isc.

The barrier must be approved for the installation location and hazardous area, and be installed

as instructed by the barrier manufacturer.

The barrier ground must be connected to the Earth Ground.

1.4 WIRING INFORMATION

When installed in the United States in a Class I Division 1 hazardous location, all customer wiring

to the AutoPILOT connections with entity parameters must be made according to Article 504

(Intrinsically Safe Systems) of the National Electrical Code, NFPA 70, including wiring and sealing

methods. For Canadian Class I Division 1 installations, all customer wiring to the AutoPILOT

connections with entity parameters must be made according to Section 18-066 of the CanadianElectrical Code. Multiple circuits that run in the same multiple-conductor cable must have a

minimum insulation thickness of 0.01 inch (0.25 mm) on each conductor.


8/70


2.0 AutoPILOT SYSTEM LISTING

The System Listing of the AutoPILOT includes power systems, RS-232 communication ports,

connections to a standard suite of analog/digital transmitters, connection to up to four

AutoMITTERs, one dedicated external RTD input, and connections to the AutoPULSE Indexer. The

System listing provides two power options: an internal battery with external solar panel, or one of

the Intrinsically Safe COMmunication interfaces (ISCOM). The communication ports included inthe system listing are the Local Port (used with the CHIT) and up to three Host Ports (used with an

ISCOM). The AutoPILOT Main Board provides system termination for three analog inputs from

a suite of optional low-power transmitters, for the optional Rosemount 205 Digital Combo

Transmitter, or for the optional Honeywell MXA145 or MXG170 combination transmitters. The

Comm 3 Terminator option provides an intrinsically safe power and communication connection to

up to four AutoMITTERs wired in parallel, with each AutoMITTER having one temperature input

which can be system wired to one of the Flow Automation RTD Temperature Probe assemblies. The

RTD1 input at TB5 connects to one of the Flow Automation RTD Temperature Probe assemblies.

For positive displacement (PD) meters, a system connection may be made between the AutoPULSE

Indexer and the AutoPILOT or MEB Pulse Input Board(s).

2.1 POWER INPUT SYSTEM CONNECTION

The AutoPILOT is powered by one of two power systems: an internal rechargeable battery with an

external solar panel, or an Intrinsically Safe Communication System (ISCOM 3-0474-004 or 6V

ISCOM 3-0474-016 or 3-0474-025). ISCOM model numbers must be verified to ensure safety.

2.1.1 Internal Power Source with External Solar Panel

The intrinsically safe battery assembly consists of a +6 Vdc, 12 AH rechargeable battery with

associated protective components. The battery assembly charge is maintained with a 2-watt solar

panel. The battery assembly mounts inside the enclosure internal chassis on the backpanel, and may

be shipped outside the unit to avoid shipping damage. To install the battery assembly, lift the battery

assembly above the bracket retaining lip, and lower the battery assembly into the bracket. The power

leads from the battery assembly connect to the flow computer at the power distribution terminal

block TB1 mounted on the equipment panel at positions 1-3 (POS) and 4-6 (NEG).

Mount the solar panel assembly to the pole, route the solar panel wiring through the bottom of the

flow computer enclosure, then connect it to the two-position Molex connector of the battery

assembly.

When the battery needs to be changed, the entire battery assembly must be replaced. Order the

replacement Division 1 battery assembly from Flow Automation (PN# 3-0485-026).

2.1.2 ISCOM 3-0474-004 (Intrinsically-Safe Power and Communications)

The ISCOM 3-0474-004 provides the AutoPILOT with an intrinsically safe +6 Vdc input power, and

an RS-232 link with a Host communication port. ISCOM model numbers must be verified to ensure

safety. This option is not available for Canadian installations. When installed in a Class I Division

1 hazardous location in the United States, all customer wiring to the AutoPILOT must be made

according to Article 504 (Intrinsically Safe Systems) of the National Electrical Code, NFPA 70,including wiring and sealing methods. Multiple circuits that run in the same multiple-conductor

cable must have a minimum insulation thickness of 0.01 inch (0.25 mm) on each conductor. Refer

to the ISCOM Installation and Wiring Manual (PN# 1-0446-004) for proper installation guidelines

of the ISCOM 3-0474-004.

ISCOM 3-0474-004 Non Intrinsically-Safe Connections

The non intrinsically-safe connections of the ISCOM 3-0474-004 are made to a power source (+8

Vdc to +16 Vdc) and an RS-232 communication device. When installed in the nonhazardousarea, the power source and the communication device are not part of the Listed System and

shall not use or generate more than 250 Volts. The ISCOM 3-0474-004 when mounted inside the

AutoLINK may be installed in a Division 2 or nonhazardous area. Refer to the ISCOM Installation

and Wiring Manual (Flow Automation Part Number 1-0446-004) for proper connection of these

devices to the ISCOM 3-0474-004.

ISCOM 3-0474-004 to AutoPILOT Intrinsically-Safe Connections

The connection between the ISCOM 3-0474-004 and AutoPILOT is an intrinsically-safe connection.

The cable length between the ISCOM 3-0474-004 and the AutoPILOT shall not exceed 200 feet.

Because the AutoPILOT with Div I Comm Expansion Board option provides up to three RS-232

ports, three ISCOMs 3-0474-004 can be connected to the AutoPILOT in non-hazardous area

installations, while the AutoLINK provides only one ISCOM 3-0474-004. Only the primary

ISCOM connected to the AutoPILOT Main Board can supply power to the flow computer.

The IS Power Outputs of a secondary or tertiary ISCOM 3-0474-004 must not be connected.

Refer to Figure 2-1-1 or Figure 2-1-2 for typical System Connection wiring between the ISCOM 3-

0474-004 and AutoPILOT.

2.1.3 6V ISCOM (Intrinsically-Safe Power and Communications)

The 6V ISCOM provides the AutoPILOT with an intrinsically safe +6 Vdc input power, and an RS-

232 link with a Host communication port. 6V ISCOM 3-0474-016 is Listed for United States

installations, while the 6V ISCOM 3-0474-025 is Listed for United States or Canadian installations.

ISCOM model number must be verified to ensure safety. When installed in a Class I Division 1

hazardous location in the United States, all customer wiring to the AutoPILOT must be madeaccording to Article 504 (Intrinsically Safe Systems) of the National Electrical Code, NFPA 70,

including wiring and sealing methods. For Canadian installations, all customer wiring to the

AutoPILOT installed in a Class I Division 1 hazardous location must be made according to Section

18-066 of the Canadian Electrical Code. Multiple circuits that run in the same multiple-conductor


to the 6V ISCOM Installation and Wiring Manual (PN# 1-0474-004) for proper installation

guidelines of the 6V ISCOM 3-0474-016 or 3-0474-025.

6V ISCOM 3-0474-016 or 3-0474-025 Non Intrinsically-Safe Connections

The non intrinsically-safe connections of the 6V ISCOM 3-0474-016 or 3-0474-025 are made to a

power source (+8 Vdc to +16 Vdc) and an RS-232 communication device. When installed in the

nonhazardous area, the power source and the communication device are not part of the Listed

System and shall not use or generate more than 125 Volts. The 6V ISCOM 3-0474-016 or 3-

0474-025 when mounted inside the AutoLINK may be installed in a Division 2 or nonhazardous

area. Refer to the 6V ISCOM Installation and Wiring Manual (PN# 1-0474-004) for proper

connection of these devices to the 6V ISCOM 3-0474-016 or 3-0474-025.

6V ISCOM 3-0474-016 or 3-0474-025 to AutoPILOT Intrinsically-Safe Connections

The connection between the 6V ISCOM 3-0474-016 or 3-0474-025 and AutoPILOT is an

intrinsically-safe connection. The cable length between the 6V ISCOM 3-0474-016 or 3-0474-025

and the AutoPILOT shall not exceed 200 feet. Because the AutoPILOT with Div I Comm Expansion

Board option provides up to three RS-232 ports, three 6V ISCOMs 3-0474-016 or 3-0474-025 can

be connected to the AutoPILOT in non-hazardous area installations, while the AutoLINK provides

only one 6V ISCOM 3-0474-016 or 3-0474-025. Only the primary ISCOM connected to the

AutoPILOT Main Board can supply power to the flow computer. The IS Power Outputs of

a secondary or tertiary 6V ISCOM 3-0474-016 or 3-0474-025 must not be connected. Refer to

Figures 2-1-3 and 2-1-4 for typical System Connection wiring between the 6V ISCOM 3-0474-016

FLOW COMPUTER INSTALLATION

GROUNDING GUIDELINES

ADDENDUM - A


62/70

A-1

GROUNDING PROCEDURES FOR FLOW COMPUTER INSTALLATIONS

A proper ground connection between the flow computer and an earth-ground connection protects the

meter run and the flow computer from natural and man-made electrical transients that may be present

on the system. Several factors determine the grounding configuration of the meter-run installation,

especially the flow-computer mounting and cathodic protection of the pipeline. The flow computermay be mounted to a 2-inch vertical stand-pipe, using two 2-inch pipe clamps or U-bolts and saddle

brackets supplied with the system. The stand-pipe can be mounted directly on the pipeline using a

saddle, or be mounted in the ground. The selected method of mounting the flow computer and the

cathodic protection of the pipeline determines the grounding method to be used.

In all installations, the flow computer system must be grounded to a suitable earth-ground. The flow

computer provides a chassis ground lug located on the lower left side of the flow computer

enclosure. The lug is marked with the ground symbol. The chassis-ground wire must be a minimum

of an 12-AWG stranded wire and as short as possible. The DC resistance from the lug to earth

ground should measure less than one ohm. Install the earth ground as outlined in Articles 250

(Grounding) and 501 (Class I Locations) of the National Electrical Code for United Statesinstallations. For Canadian installations, install the earth ground as outlined in Sections 10 and 18

of the Canadian Electrical Code.

This guideline deals with the following three installation configurations:

Meter runs without cathodic protection

Meter runs with cathodic protection using isolating flanges

Meter runs with cathodic protection using isolating fittings


63/70

A-2

Meter Runs without Cathodic Protection

Flow computer installation on meter runs without cathodic protection can be mounted directly on

the pipeline or on a stand-alone vertical stand-pipe. Refer to Exhibit 1. The ground conductor

connects between the flow computer and the earth ground. The Flow Automation Temperature

Transducer may be grounded through the pipeline. If any pressure/pulse transducers orAutoMITTERS are remotely mounted, connect the chassis ground of these transducers to the

pipeline or earth ground.

Exhibit 1: Meter-Run Installation without Cathodic Protection


64/70

A-3

Meter Runs with Cathodic Protection Using Isolating Flanges

Isolating flanges can be used to electrically isolate the meter run (including the flow-computer

system, the orifice/turbine meters, and AutoMITTERs) from the pipeline with cathodic protection.

The flow computer can be mounted directly on the isolated section of pipeline or on a stand-alone

vertical stand-pipe. Refer to Exhibit 2. The ground conductor connects between the flow computerand the earth ground. Mount a ground strap to the isolated meter-run section and connect it to the

earth ground to protect the Temperature Transducer and any remotely mounted pressure/pulse

transducers. Connect any AutoMITTER grounds directly to earth ground.

Exhibit 2: Meter Run Installation with Isolating Flanges


65/70

A-4

Meter Runs with Cathodic Protection Using Isolating Fittings

Isolating fittings can be used to electrically isolate the meter run from the pipeline with cathodic

protection. Refer to Exhibit 3. Install an isolated fitting or gasket between the following

connections:

all metallic tubing runs between the orifice meter and pressure transducers/manifolds (includingremotely mounted units or AutoMITTERs)

all metallic connections or tubing runs between the flow computer and turbine meter/pulse

transducers

any Temperature Transducer and its pipe-mount, including those connected to AutoMITTERs

Mount the flow computer on a stand-alone vertical stand-pipe. The ground conductor connects

between the flow computer and the earth ground. Connect the cases of the Temperature Transducers,

any remotely mounted pressure transducer cases, or AutoMITTER chassis grounds, to the earth

ground.

RTD PROBE CUTTING

AND WIRING PROCEDURES

ADDENDUM - B


67/70

B-1

1.0 CUTTING THE TEMPERATURE PROBE TO LENGTH

Flow Automation recommends the temperature probe length be measured from the inside bottom

surface of the RTD Housing to the desired depth in the thermowell. This measurement takes into

consideration the combined lengths of the thermowell and mounting hardware when the temperature

probe is installed on the pipeline. When installed in the thermowell, the tip of the probe must notcontact the bottom of the thermowell, to electrically isolate the probe from transient currents. Cut

the temperature probe as follows:

1. Measure or calculate the desired length of the temperature probe.

2. Remove the heat shrink from the top of the temperature probe.

3. Carefully, remove the small plastic sleeve from the top of the temperature probe. Caution: Do

not discard the small plastic sleeve. It protects the wires from the edge of the probe.

4. Measure and mark the body of the temperature probe to the desired length, measuring from thetip of the temperature probe.

5. When using the standard Stark temperature probe, the composite-probe body is pre-scored.

Hand break the probe body at the desired score, then pull the portion to be removed from the
