Figure 96: Relay Connection Terminal Block P4
Each relay connection is clearly marked. Relay 1 is Status , Relay 2 is Service , Relay 3 is
Mode , and Relay 4 is Control . The relays can be connected either as normally open (NO)
whereby the circuit is only complete when the relay is energized or as normally closed (NC)
whereby the circuit is complete when the relay is deenergized. There are also 4 solenoid
connections at terminal block P6 on the IO board.
To test the digital outputs, follow the procedure below.
1. Ensure that Direct Board Control Enable is selected on the Manual Override page.
2. Test each relay. If the relay is currently deenergized, the circle will be grey, and the
checkbox will be empty. If the relay is currently energized, the circle will be red, and
the checkbox will have a checkmark in it. To energize a deenergized relay, simply
place a checkmark in the checkbox by clicking on it. To deenergize an energized relay,
remove the checkmark in the checkbox by clicking on it. Confirm with the control room
that the signals are being received correctly. If the install location is not too loud, it
should also be possible to hear an audible ‘click’ when a relay is energized and
deenergized.
3. Test each solenoid if necessary. If the solenoid is currently deenergized, the circle will
be grey, and the checkbox will be empty. If the relay is currently energized, the circle
will be red, and the checkbox will have a checkmark in it. To energize a deenergized
solenoid, simply place a checkmark in the checkbox by clicking on it. To deenergize
an energized solenoid, remove the checkmark in the checkbox by clicking on it.
Solenoid energization and deenergization should produce audible clicks as the
solenoid actuates.
