If you have trouble operating wired signal circuits, follow these troubleshooting steps:
1. Signal circuits not responding to programmed events:
a. Make certain that the system controller status is set to AUTO:
Press 8 , enter User Lock, if applicable, and press O .
b. Confirm that signal circuits are enabled. From the View Circuits screen:
Press 3 to enter the Enable Circuits screen to view or change the control status of individual circuits.
c. Confirm that signal circuits and events programmed to control them are assigned to the same schedule.
d. Check for correct voltage at signal relay contacts. The COM (common) terminals should measure full voltage all the time.
The NO (normally open) terminals should have power only when the circuit is activated.
2. Signal circuit(s) On when they should be Off:
a. Press
M , enter User Lock, if applicable, and press O . Then choose circuit(s) to activate/deactivate.
b. If the circuit does not toggle On or Off, check for stray voltage on the signal relay normally open contacts.
n Note: You can try disabling the surge protection circuitry by switching it off (see diagram). These switches are located
inside the wiring compartment. Remove power to the System Controller and signal circuit lines before removing cover
to access wiring.
c. Verify the LED for the circuit is Off (see diagram).
3. Signal circuits not responding at all:
a. Carefully open the top cover of the SiteSync IQ System Controller by removing the screws on each side of the unit.
b. Press the M key, enter User Lock, if applicable, then press O .
c. Choose the circuit(s) you wish to test and press the M key to trigger the applicable relay(s).
d. Observe the LED(s) next to the circuit relays being tested. If they light up when the circuit is being triggered, verify the
operation of the relay by measuring the voltage on the relay terminals. The NO terminal should have power. If they don't
light up, verify the circuits are enabled (see Step 1b above).
If the problem cannot be resolved after following these steps, please call Technical Support at American Time at 800-328-8996.
