DIAGNOSTICS Menu

Compressor Trip
(Ckt-1 or Ckt-2)

Used With: See 
compressor protection 
devices on MCM control 
wiring schematic.

Module: MCM

Problem: The compressor 
proving input for the given 
circuit has been detected 
open continuously for more 
than 3 seconds during 
compressor operation.

Check: All compressor 
protection devices in the 
associated refrigerant 
circuit’s 115v contactor 
control wiring circuit.

All compressors on the 
associated circuit will be 
locked out and prevented 
from operation.

(PMR) A manual reset is 
required after this 
diagnostic occurs. The 
Diagnostic can be reset by 
the unit mounted Human 
Interface Module or Tracer, 
or by cycling power to the 
RTM.

Condenser Pressure 
Sensor Failure (Ckt-1 or 
Ckt-2) 

Used With: DX cooling w/
water cooled condensers.

Module: MPM

Problem: The saturated 
condenser pressure sensor 
input is out of range for the 
given circuit.

Check:  Wiring from the 
MPM to the pressure 
sensor. The input voltage 
range should be between: 
0.625 and 4.80VDC. 

All compressors on the 
associated circuit will be 
locked out and prevented 
from operation.

(PAR) An automatic reset 
occurs after the Condenser 
Pressure Sensor input 
returns to within range for 
10 continuous seconds. 

Condenser Sump Heater 
Failure Manual

Used With: DX cooling w/
water cooled condensers 
w/sump heater.

Module: MCM

Problem: The sump min 
level switch is CLOSED, and 
the Sump Water 
Temperature is less than 
37.5 F, and has remained 
this way for 20 minutes.

Check: Actual water level, 
minimum level switch, 
heater power circuitry.

The unit will perform Sump 
Water Freeze Protection 
function.

(PMR) A manual reset is 
required anytime after the 
Diagnostic is set to re-
enable compressor 
operation. The Diagnostic 
can be reset by the Human 
Interface or Tracer, or by 
cycling power to the RTM.

Condenser Sump Pump 
Manual Fail

Used With: DX cooling w/
water cooled condensers.

Module: MCM

Problem: Sump Pump 
contactor auxiliary 
contacts do not close (state 
change), within 6 seconds, 
when the pump is 
requested ON for 
mechanical cooling, or are 
open for 6 continuous 
seconds during compressor 
operation.

Check: Wiring to sump 
pump, contactor, and 
auxiliary contacts. Check 
for pump operation.

A compressor lockout is 
generated on all circuits.

(PMR) A manual reset is 
required anytime after the 
Diagnostic is set to re-
enable compressor 
operation. The Diagnostic 
can be reset by the Human 
Interface or Tracer, or by 
cycling power to the RTM.
