If you have trouble operating wired clock circuits, follow these troubleshooting steps:
1. Ensure you have the clock code configured in your system controller:
a. Press
P7
to enter the Config Menu
b. Enter your Service Lock if necessary.
c. Press
4
to enter the Clock Code select screen and verify that it is correct.
2. If the system controller time was recently changed, allow up to 24 hours for secondary clocks to re-synchronize to the
system controller.
3. Ensure there is sufficient voltage across each secondary clock.
4. If fewer that 25 AllSync secondary clocks are connected to the system controller, the secondary clocks might not recognize
the correction from the system controller. Connect all intended clocks and allow time for normal system controller correction.
If secondary clocks still have not corrected, you may need additional hardware. Contact American Time Technical support for
information on adding a Resistor Pack (Part #H001941) to your system.
If the problem cannot be resolved after following these steps, please call Technical Support at American Time at 800-328-8996.
