05701-A-0550 5701 CONTROL SYSTEM OPERATING

The system consists of individual 1” (2.54cm) wide cards fitted to a rigid custom rack designed to fit Euro rack cabinets. Two rack widths
are available:
a. 19 inch with 17 card slots to house up to 16 Channel Control Cards and an Engineering Card.
b. Half 19 inch with nine card slots to house up to eight Channel Control Cards and an Engineering Card.
Each sub-rack contains an Engineering Card and a DC Input Card to make up the rack system
The system is designed to meet the differing customer wiring configurations and to achieve this the control functions are split away
from the relays and field wiring connections. A single channel of gas detection therefore consists of:
a. Sensor Drive Module
In order to achieve compatibility with a range of different inputs and sensor types, the circuitry necessary to control the sensor is
housed on an independent plug-in Sensor Drive Module. These modules plug directly into a Channel Control Card and are factory
fitted. There are two different modules, one for catalytic inputs and one for 4 – 20mA inputs.
b. Single Channel Control Card
Each Single Channel Control Card functions independently and contains all the necessary electronic circuitry to provide the sensor
drive, alarm detection and gas level display for that channel of gas detection.
c. Field Interface or Relay Card
The Field Interface/Relay Cards provide the interface connections between the Control Cards and their respective field connected
gas sensor. In addition, Relay Cards provide alarm outputs to the field connections.

In a system where the field wiring is required to be connected to the
rear of the system, the rack is centrally divided into front and rear
sections by a printed circuit board backplane which provides common
power and signal routeing between individual Channel Control Cards.
Channel Control Cards are fitted at the front of the rack while Interface/
Relay cards are fitted directly behind the Channel Control Cards at the
rear of the rack. The Channel Control Cards and their respective
Interface/Relay Cards are interconnected by a plug and socket
arrangement.
In a system where the field wiring is required to be connected to the
front of a system, the Channel Control Cards and Interface/Relay
Cards are mounted one above the other in a 6U rack. The backplane
printed circuit board still provides the common power and signal
routeing between the individual Channel Control Cards while short
cables at the rear of the cards connect each Channel Control Card to
their respective Interface/Relay Card.
Simple calibration and checking of the system is carried out using
push buttons on the Engineering Card fitted to each rack. More
complex configuration can be carried out using the RS232 link between
the Engineering Card and an external IBM compatible personal
computer running the engineering interface software.
