Apply Power
Before connecting the AC power to the AC terminal on the termination
block make sure that POWER Switch on the unit is in OFF or ‘0’ position.
Flip the Power switch to ON or ‘1’ position to turn on the power to the
monitor and verify 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.
