off. This event will cause a lockout of the compressor
and indicates that the module is mis-wired or the
contactor coil is shorted to ground.
NOTICE
Code 10 is not specifi ed on the module label.
Resetting Alert Codes
When the CoreSense Diagnostics module has detected
a series of adverse conditions that have caused it to
lockout the compressor, and after the issue has been
resolved, it is necessary to manually reset the module
in order to clear the present alert code.
The primary way of clearing the code and resetting
the ALERT or TRIP/LOCK is to cycle the power to the
module by disengaging the COMMON (C) Terminal.
This will not clear the seven day operating history
contained in the module memory. It will only clear the
present ALERT or TRIP/LOCK and allow for normal
operation.
SERVICE
WARNING
Always disconnect and lockout the power supply
before beginning electrical troubleshooting.
