The purpose of Diagnostic #2 is to test the
Movement gearbox and electrical components of
your clock.
Diagnostic #2 may be enabled by holding down the
diagnostic button for three seconds. If the Valcom
Wired clock is performing this diagnostic, then a
green LED on the movement will flash twice every
three seconds. It will continue to flash twice every
three seconds until the diagnostic is complete. The
clock will confirm that the diagnostic is complete
when the LED shines a different color:
If the LED is shining a solid green:
The second hand will display the protocol and polarity that was detected. See the table on the previous
page for details.
The minute hand will display the software version number.
If the LED is flashing red:
The hour hand will display how much time has passed since the clock last received a communication signal:
Diagnostic Test #2 - Comprehensive Test (Original Only)
The clock hands will remain on these numbers for three minutes, and then the clock will revert to
displaying the accurate time.
