ALARM BOARD CONNECTIONS
FOR NORMALLY CLOSED "NC" OPEN-ON-ALARM STRATEGY
IMPORTANT:
LED display board is shipped loose to protect it from possible damage during
installation of the wiring to main controller board and/or the alarm board. It is polarity
sensitive and is keyed so it can only be installed in correct position (see
ALARM LED
DISPLAY BOARD
on page 54).
NOTE 1:
2nd Stage, Econ 1, Econ 2, High Temp 2 and Controller alarms are only on -B
alarm board. All other alarms are on both -A and -B alarm boards.
