Fig. 21 -- CADM Housing/LED Locations
The TRIP LED indicates either a time-delay period is
currently active (RED LED is blinking) or the module has
locked out the compressor (RED LED is on steady). A
lockout condition will occur when the CADM detects a
thermostat demand at input Y but there is no power at the
compressor line terminals T1 or T2 or T3. This lockout
can occur due to a safety switch (LPS or HPS) opening
and de-energizing the compressor contactor, the
compressor-motor internal overload opens, or other
internal power interruption has occurred. Reset of the
TRIP LED requires that unit main power be recycled after
the loss of power to the compressor condition has been
detected and corrected.
Simultaneous Blinking of YELLOW and RED LEDs
indicates control power input to the CADM is low. Check
control circuit transformer and wiring.
Troubleshooting the CADM Wiring – Flashing LEDs also
indicate wiring problems to the CADM. See Table 10 for
discussion
of additional
LED flash
codes and
troubleshooting instructions.
