Diagnostics
MP: Could not Store Starts
and Hours
Warning Latch MP has determined there was an error with the previous power down
store. Starts and Hours may have been lost for the last 24 hours.
Remote
MP: Non-Volatile Block Test
Error
Warning Latch MP has determined there was an error with a block in the Non-Volatile
memory. Check settings.
MP: Non-Volatile Memory
Reformat
Warning Latch MP has determined there was an error in a sector of the Non-Volatile
memory and it was reformatted. Check settings.
Remote
MP: Reset Has Occurred Warning NonLatch The main processor has successfully come out of a reset and built its
application. A reset may have been due to a power up, installing new
software or configuration. This diagnostic is immediately and
automatically cleared and thus can only be seen in the historic
diagnostic list.
NA
Outdoor Air Temp Sensor Warning
and
Special
Action
Latch Bad Sensor or LLID. If configured as a CCA this diagnostic shall turn on
all fans and use a minimum LPC ignore time of 30 seconds.
Remote
Phase Reversal Immediate Latch A phase reversal was detected on the incoming current. Local
Power Loss Immediate NonLatch The compressor had previously established currents while running and
then all three phases of current were lost. Design: Less than 10%
RLA, trip in 2.64 seconds. This diagnostic will preclude the Phase Loss
Diagnostic from being called out. To prevent this diagnostic from
occurring with the intended disconnect of main power, the minimum
time to trip must be greater than the guaranteed reset time of the
Starter module. This diagnostic will auto reset in 10 seconds from its
occurrence, and is not active during the start mode.
Remote
Starter Contactor Interrupt
Failure
Immediate
and
Special
Action
Latch Detected a maximum chiller current greater than 10% RLA on any or
all phases when all compressors were commanded off. Detection
time shall be 10 seconds maximum. On detection and until the
controller is manually reset: generate diagnostic and energize the
appropriate alarm relay. Anytime the condition is present energize the
liquid line solenoid valves, continue to energize the Evaporator Pump
and Condenser Pump if CGWF or if CCAF energize the Condenser
Fans according to the fan staging algorithm.

Starts/Hours Modified -
Compressor X
Warning NonLatch A counter for compressor starts or hours has been modified by
TechView. The diagnostic shall indicate compressor A or B. This
diagnostic is immediately and automatically cleared and thus can only
be seen in the historic diagnostic list.
NA
Suction Pressure Transducer Immediate Latch Bad Sensor or LLID Remote
Excessive Loss of Comm Immediate Latch Loss of comm with 20% or more of the llids configured for the system
has been detected. This diagnostic will suppress the call out of all
subsequent comm loss diagnostics. Check power supply(s) and
power disconnects - troubleshoot LLIDS buss using TechView
