2.
Open the contact connected to this input and check that the display shows this state.
b) USER INPUT A SETPOINT SET TO "ALARM"
1.

USER INPUT A RELAYS (3-7)
USER INPUT A DELAY
3.
For
INPUT ASSERTED LOGIC
3.1.
Check that there is no logic input diagnostic message on the display.
3.2.
Set the monitored contact for the logic input programmed in setpoint
Note that the corresponding virtual input will have no affect.
3.3.
Check that the diagnostic message, either User Input A or the name programmed in setpoint User Input A
Name, appears on the display with the Auxiliary LED and relay activated. Check in the Event Recorder that the
selected function has been invoked.
3.4.
Set the monitored contact for the logic input programmed in setpoint
Again note that the corresponding virtual input will have no affect.
3.5.
Check that the diagnostic message is removed from the display with the Auxiliary LED and relay deactivated.
3.6.
Repeat Steps 3.1 through 3.7 for all functions programmed to be asserted by a Contact Close input.
4.
For
INPUT ASSERTED LOGIC
4.1.
Check that there is no logic input diagnostic message on the display.

Set the monitored contact for the logic input programmed in the
state. Note that the corresponding virtual input will have no affect.
4.3.
Check that the diagnostic message, either User Input A or the name programmed in setpoint User Input A
8
Name, appears on the display with the Auxiliary LED and relay activated. Check in the Event Recorder that the
selected function has been invoked.
4.4.
Set the monitored contact for the logic input programmed in setpoint User Input A Source to the closed state.
Again note that the corresponding virtual input will have no affect.
4.5.
Check that the diagnostic message is removed from the display with the Auxiliary LED and relay deactivated.
4.6.
Repeat steps 4.3 through 4.7 for all functions programmed to be asserted by a Contact Open input.
