8.2INPUTS/OUTPUTS 8.2.1 LOGIC/VIRTUAL INPUTS 1 TO 14
a) ACTUAL VALUES DISPLAY
For these first tests, the
INPUT 1 (14) ASSERTED LOGIC setpoints should be programmed as "Closed | Von". Under the A1 STA-
TUS ÖØ VIRTUAL INPUTS Ö LOGIC INPUT 1 (14) subheading,
1. Turn on this input and check that the display shows this state.
2. Turn off this input and check that the display shows this state.
Under the
A1 STATUS ÖØ HARDWARE INPUTS ÖØ CONTACT 1 (14) STATE subheading:
1. Close the contact connected to this input and check that the display shows this state.
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. Set all inputs 1 through 14, both contact and virtual, to the de-asserted state.
2. Enter (example) settings under subheading
S3 LOGIC INPUTS ÖØ USER INPUT A
USER INPUT A NAME: "User Input A"
USER INPUT A SOURCE: "Input 1"
USER INPUT A FUNCTION: "Alarm"
USER INPUT A RELAYS (3-7): "3----"
USER INPUT A DELAY: "0.00 s"
3. For INPUT ASSERTED LOGIC setpoints set to "Contact Close",
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
USER INPUT A SOURCE to the closed state.
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
USER INPUT A SOURCE to the open state.
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 setpoints set to "Contact Open":
4.1. Check that there is no logic input diagnostic message on the display.
4.2. Set the monitored contact for the logic input programmed in the
USER INPUT A SOURCE setpoint to the open
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
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.
5. For
INPUT ASSERTED LOGIC setpoints set to "Virtual On":
5.1. Check that there is no logic input diagnostic message on the display.
5.2. Set the monitored virtual input for the logic input programmed in setpoint message
USER INPUT A SOURCE to the
on state. Note that the corresponding contact input will have no affect.
