The 2402 Combustible Gas Controller, for FG/ESD 2400 System, has
been designed to interface with the majority of 0÷22mA Combustible
Gas Transmitters or SMART Sensor family using 2, 3 or 4 wire
connections. This card provides two isolated analogue channels
showing the combustible gas level (in L.E.L. percentage) on two
digital displays, used also for other service codes. All these
information’s are converted in digital format and transmitted to
the 2401-CPU Facility module. The 0÷22mA analogue input channels
coming from Transmitters or Smart Sensors are connected to the
input circuits (isolated amplifier) and they’re converted from
voltage levels to digital values through an A/D converter (12 bit
resolution) which writes digital data on the bus of the 8 bit
microprocessor. The detected gas level is displayed on the digital
displays, but on the front panel there are also double LED’s for
the status of each channel (Ready, Fault, Warning and Alarm
condition). Each information is written by the microprocessor on
the input table, which is regularly inquired by the 2401-CPU
Facility module, using the proprietary communication software,
through a high speed RS 485 serial line. The Warning and Alarm set
points are stored on the 2401-CPU Facility module by the
Programming Software and during the system start-up are transferred
to the 2402 card. Each analogue channel is automatically tested by
the microprocessor using a diagnostic routine in order to check the
correct operation of the analogue and digital logic circuits. This
diagnostic procedure is performed by forcing alternatively each
analogue circuit using a pre-fixed current which is read and
compared with some programmed values, simulating the presence of
combustible gas. In case of discrepancy, the microprocessor will
detect it, displaying the Fault state and sending a Fault message
to the 2401-CPU Facility module. Furthermore, to assure the correct
functionality of the card a Watchdog (WD) timer circuit provides
the monitoring of the card operation via a digital output. This is
performed during the same diagnostic software routine by the
microprocessor. The Watchdog Circuit State is displayed with front
panel LED’s and available on a normally Energised (N.E.) relay with
SPDT contacts (on the I/O connector). In case of a microprocessor
failure, the Watchdog will turn to Alarm condition, switching off
the front panel LED’s and will de-active the relay. The front card
panel is composed by two displays (with 2 digits each); some double
LED’s for the indication of Ready, Warning, Alarm and Fault status
for each channel; serial line LED’s which display the communication
condition between the 2402 card and the system; a double LED which
displays the WatchDog condition; some push buttons for the
execution of local commands. These push buttons permit the
execution of the following actions: SEL → Input channel selection
INH → Inhibition of the selected channel SET → View set point of
Warning and Alarm of selected channel TEST → Activation of the an
auto-test card function and front Lamp test The frontal push
buttons can be used only if they were activated by the Facility
2401 module. A particular feature of this card is that it can be
easily checked while powered, without affecting its normal
operation and specially the system integrity. To perform all the
maintenance operations the cards is provided a front connector, for
the connection of the Hand Held Monitor (2490 HHM). Using the Hand
Held Monitor is possible to read the set point values, read the
L.E.L. level and is also possible to force the analogue inputs, in
order to test the application software and logic’s. 8 (Eight)
auxiliary Open Collector outputs (Max 100mA @ 30Vdc) are available
on the I/O connector for the connection of relays, LED’s, or other
notification devices. These O.C. outputs are activated by
microprocessor following the programmed instructions, related the
channels status. Card with appropriate firmware to operate the
condition FAIL-TO-SAFE in case of communication or CPU failures
through the Open Collector output .
