2.3 ALARM FUNCTIONS AND CONTROLLER CONFIGURATION
Model 1
0 control modules incorporate several user selectable alarm programming options and general operating
options that are accomplished via dip switches. These options include latching of relays, energized/de-energized relays,
and alarm firing direction. Reference Figure #1 for the applicable dip switch locations and settings.

tion slide the switch to the off position. The switch locations are as follows: fault – SW2-2, alarm 1 - SW2-8, and alarm
2 – SW2-5.

All alarms relays — alarm 1, alarm 2, and fault — can be switch programmed as normally energized or normally de-ener-
gized. The standar
d is de-ener
gized. However, a relay can be programmed as energized to provide application specific
features. A normally energized relay will de-energize when in alarm. A typical application of the energized configuration
