Diagnostic Table - Colorado time systems GEN7 User Manual

Diagnostic Table

During both pre-meet and real-time diagnostics, the Gen7 screen will show each input in one of
4 states:
Open
Shorted
Corrosion
Closed
Having a known-good pushbutton that is free of corrosion can make diagnosing pad/button
issues much easier.

This is the normal state for a touchpad or pushbutton that has not
been pressed. If this is displayed after pressing a touchpad or
pushbutton, the pad/button should be tested with a touchpad meter
(TPM-D). If the pad/button registers as good with the meter, there may
be an issue with the deckplate or cable-harness
If this is displayed before pressing a touchpad or pushbutton, it could
be a sign that there is a short in the pad/button. If the pad/button is
removed and the short goes away, replace the pad/button. Ensure that
the deckplate/cable-harness pod is as dry as possible and retest. Test
the pad/button with a touchpad meter (TPM-D) and replace if
necessary.
If this is shown after pressing a touchpad or pushbutton, it could be a
sign that either the plug or jack is corroded. Examine the plug on the
pad/button and clean with rubbing alcohol. Use a cotton-swab and
rubbing alcohol to clean deckplate and cable-harness jacks.
If this is present without pressing a touchpad or pushbutton, it could be
a sign of a shorted input that is also corroded.
If the corrosion indicator goes away after retesting with a known-good
button, the issue is in the pad/button. If the issue persists, the issue is
in the wiring.
