Display, Alarm and Error Messages
When an alarm or error condition is detected, “Ft” appears in the left display and a corresponding code flashes on the right display. Operational limit
parameter alarms will shut down compressor, fan, pump and heaters. Alphabetical codes will also appear on the right display. An audio alarm will also sound.
After taking corrective action, restart unit to clear fault or error.

Code = 02

Action required = Alarm – Process fluid temperature is above factory set high temperature cutout.
On air-cooled condenser units the cutout will reset automatically after the temperature of the fluid is lowered. On water-cooled condenser
units the cutout must be manually reset after the temperature of the fluid is lowered. A red button is accessible through the rear panel.
Default = Units without heater option “OTP” jumpered on PCB

Automatic Restart from Alarm Mode
This Chiller is equipped with an automatic restart feature to avoid false alarms. If any alarm condition is detected the chiller will turn off, wait 30 seconds and then turn on.
This is to avoid nuisance trips due to temporary flow obstructions, temperature swings or electrical line noise.
Three restart attempts will be made. If the alarm condition continues to exist then an alarm will sound and the chiller will remain off until the problem is corrected.
