Start Up
Complete the following procedures for the normal unit operation.
1.
Complete the mounting and wiring procedures described in earlier
sections.
2.
Follow gas sensor & transmitter operation manual for proper wiring of
sensors with the monitor.
3.
Verify all the wiring connections to be correct and secure.
4.
Verify that all the control modules are secured with captive screws on the
front panel.
Apply Power
Verify all the sensor and alarm relays connections. Apply the DC power and
then check the following conditions.
1.
All the installed control modules will display their corresponding channel
number on the display (channel 1 thru 12). For example the control
module in the slot 1 will display 01, module in slot 2 will display 02 and so
on. The channel number will rapidly flash for few seconds.
2.
Each control module will then display low, high and High-High alarm set
points. The visual alarm LED indicator will be lit while the unit displays
the alarm set point.
3.
The control module goes into normal operation and starts reading signal
from the sensor / transmitter.
Note: If a control module display remains blank upon power up or the
channel number flashing is incorrect then remove the control module and
reinsert into card guides in order to properly snap into the card edge
connectors on the termination board.
