INSTALLATION

The controller is desi g ned for wall mounting in a control room or working area. The enclosure incorporates a sub

panel assembly and window.

1. CONTROLLER INSTALLATION/MOUNTING

Securely mount the controller to the wall using four (4) mounting screws with lock washers and nuts. Make

sure there is room for the door to open.

2. INTERCONNECT WIRING

Interconnect wiri n g is identified in the customer wiring diagram drawings in this manual. It is recommended that

all wiri n g is shielded and common shielding practices be used for installation to reduce the possibility of radi o

frequency interference.

Step 1: Connect sensor to the interconnect cabl e . Record wire colours and what terminals they are connected

to. See sensor information as to number of wires used and their connection.

Step 2: Terminate the other end of the interconnect cable from sensors at the connectors located insi d e the

controller on the upper right of the motherboard. Observe correct polarity between sensor and

controller connections. Failure to do so may result in damage to ampl i fier circuits.

Interconnecting wiri n g between controller and sensors

Step 1: Terminate wiring to alarm output connectors as identified in customer wiri n g diagram drawing.

Step 2: Terminate power supply input wiri n g as identified in customer wiring diagram.

Step 1: Check all wiring for correct polarity and good terminal connections.

Step 2: Appl y power and observe visual indi c ators.

- Input Module indi c ator lights may cycle between off, green, red and yell o w upon start up.

sensors will require a stabilization period. Consult specificati o n for the particular sensor

Step 3: Check voltage reading at each sensor.

This measurement will depend upon main power supply setting.

- +12 VDC to 14 VDC between (+) and (-) terminal connections.

5. INSTRUMENT START-UP

Step 1: Let the sensor settle after power has been appl i ed. See sensor data for settling time.

Step 2: A zero air sample should be applied to each sensor to check absolute zero when a continuous gas

background exists in the area where the sensor is installed.

NOTE: Airtest gas monitors are shipped cali b rated and should not require any adjustment provided voltage

reading and operational tests give correct indi c ation. However, it is recommended that a cali b ration

test be performed after installation.

Step 3: Testing of response to the presence of gas using a test sample or cali b ration sample of gas should be

appl i ed to each sensor.
