LESSON SUMMARY: This lesson is designed to assist the user in troubleshooting issues related to buttons on the keypad not working.
Special Tools Needed: Phillips Screwdriver
⚠ CAUTION: THIS LESSON MAY INCLUDE INSTRUCTIONS TO TEST HAZARDOUS VOLTAGES (120V-240V) THAT CAN CAUSE SERIOUS INJURY OR DEATH. IT IS RECOMMENDED THAT A LICENSED ELECTRICIAN BE CONTRACTED TO PERFORM SUCH TESTS.
🛑 STOP: ALWAYS TURN OFF THE POWER TO THE SATELLITE BEFORE REMOVING OR INSTALLING COMPONENTS.
If buttons are not functioning properly on a keypad, there is most likely an issue with the Timing Mechanism itself. To determine if the Timing Mechanism requires replacement, proceed with the following steps:
Start by powering off the satellite using the On/Off switch on the Power Supply Assembly. *Note: The location of the Power Supply Assembly will vary based on your system type and satellite configuration.
Next, unplug all ribbon cables on the Timing Mechanism from any corresponding components in the satellite.
Remove the Timing Mechanism from the satellite and take it to a known-working satellite location to test.
*Note: Prior to installing the Timing Mechanism at a known-working satellite location, be sure to power off the satellite at the known-working satellite location. Power to the satellite should always be off before installing or removing components.
If the buttons on the keypad are not functioning properly when installed in a known-working satellite location, the Timing Mechanism is damaged and needs to be replaced.
If the buttons on the Timing Mechanism are functioning properly at the known-working satellite location, reinstall the Timing Mechanism at the original satellite and search Techbook on how to further troubleshoot a malfunctioning Timing Mechanism for your specific control system.
