MP Application Mem-

ory CRC Error

Immediate

Latch

App software inside the MP failed its own checksum test. Possible

causes: application software in the MP is not complete - software

download to the MP was not completed successfully - or MP hard-

ware problem. Note: User should attempt to reprogram the MP if

this diagnostic occurs.

Remote

6A1

MP: Could not Store

Starts and Hours

Info

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

5FF

MP: Invalid Configu

ration

Immediate

Latch

MP has an invalid configuration based on the current software

installed

Remote

6A2

MP: Non-Volatile

Block Test Error

Info

Latch

MP has determined there was an error with a block in the

Non-Volatile memory. Check settings.

Remote

69C

MP: Non-Volatile

Memory Reformat

Info

Latch

MP has determined there was an error in a sector of the Non-Vol-

atile memory and it was reformatted. Check settings.

Remote

MP: Reset Has Oc-

curred

Info

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, install-

ing new software or configuration. This diagnostic is immediately

and automatically cleared and thus can only be seen in the His-

toric Diagnostic List in TechView

Remote

297

No Differential Re-

frigerant Pressure

Immediate

Latch

The system differential pressure was below 7.7 Psid. The occur-

rence of this diagnostic will saturate the above “Low Diff Rfgt

Press” Integral and invoke the same “Compressor Cool Down” op

mode.

Remote

1E1

Oil Flow Protection

Fault

Immediate

Latch

The Oil Pressure Transducer for this Chiller is reading a pressure

either above its Condenser Pressure by 15 Psia or more, or below

its Evaporator Pressure 10 Psia or more for 30 seconds continu-

ously.

Info and Spe-

cial Action

Latch

Bad Sensor or LLID. This diagnostic will only occur if OA sensor

is configured.OA Chilled water reset will be suspended if selected

and Tracer OA unavailable.

Remote

Over Voltage

Normal

NonLatch

a. Average of all monitored Line voltages above + 10% of nom-

inal. [Must hold = + 10 % of nominal. Must trip = + 15 % of

nominal. Reset differential = min. of 2% and max. of 4%. Time

to trip = minimum of 1 min. and maximum of 5 min.) Design:

Nom. trip: 60 seconds at greater than 112.5%, + or - 2.5%,

Auto Reset at 109% or less.

Remote

Phase Loss

Immediate

Latch

a) No current was sensed on one or two of the current transform-

er inputs while running or starting (See Nonlatching Power Loss

Diagnostic for all three phases lost while running). Must hold =

20% RLA. Must trip = 5% RLA. Time to trip shall be longer than

guaranteed reset on Starter Module at a minimum, 3 seconds

maximum. Actual design trippoint is 10%. The actual design trip

time is 2.64 seconds. b) If Phase reversal protection is enabled

and current is not sensed on one or more current xformer inputs.

Logic will detect and trip in a maximum of 0.3 second from com-

pressor start.

Local

E5 or

Phase Reversal

Immediate

Latch

A phase reversal was detected on the incoming current. On a

compressor startup the phase reversal logic must detect and trip

in a maximum of 0.3 second from compressor start.

Local

Phase Unbalance Se-

vere Current Imbal-

ance

Normal

Latch

A 30% Phase cCurrent Unbalance imbalance has been detected

on one phase relative to the average of all 3 phases for 90 con-

tinuous seconds.
