10 Fault Compressor Lockout
Ten compressor faults have occurred since the unit was last reset. This condition indicates that a repetitive compressor
fault is present. See the history log to determine the mode of operation to assist in determining the cause of the lockout.
Sensor Failure (All Sensors)
The controller has detected that the value of a system sensor is outside of the expected range. The alarm screen will show
which sensor has failed. The most likely cause is a defective sensor.
Expansion Board Comm Failure
The main control module CM1 is unable to communicate with the expansion card, CM2. The most likely cause is a
blown fuse on the control module CM2.
FAULT HISTORY LOG
To assist in troubleshooting, the ECC III maintains a log of the 50 most recent faults. The log contains the date and time
of occurrence, along with the fault code and a snapshot of system conditions at the time of the fault.
The fault history log is accessed from the System Status Information menu. Press the III key to access the menu and then
press the UP arrow key until the fault history screens are displayed. There are two screens on SWHP60-190 units and a
third screen on SWHP220-340 models.
Each fault in the log is assigned a number from 1 to 50. Fault number 1 is the most recent and 50 is the oldest. To cycle
through the list of faults, move the cursor to the fault number on any of the fault history screens and then press ENTER.
Use the UP and DOWN arrow keys to cycle through the fault history screens one at a time. To go to the next fault, repeat
these steps.
All fault history screens display the following parameters:
Date @ Time - Date and time the fault occurred. The date is in MMDD format. The time is in 24-hour format, HHMM.
FC: - Code number assigned to the fault. The codes are as follows:
2 - Power Restored
3 - Return Fan Motor Not Running
4 - Supply Fan Motor Not Running
5 - Fire Trip Active
6 - Smoke Purge Active
7 - Space Temperature Out of Range (<60°F to >105°F dry bulb, <55°F wet bulb)
8 - Supply and Return Fan Motors Not Running
9 - Supply Temperature Less than 40°F
