ROUBLESHOOTING
Most Thermolator malfunctions are indicated by an illuminat-
ed alarm light and error codes displayed on the control panel.
A problem can trigger three types of alarms:
l Shut Down Alarms: The Thermolator detected a problem
that caused it to shut down automatically to prevent equip-
ment damage or personal injury.
l Warning Alarms: The Thermolator continues to operate,
but warns of a problem that could lead to a condition that
will shut down the unit.
l System Errors: The system error codes indicate a non-
recoverable problem with the microprocessor control.
When the Thermolator control detects a problem, the red
Alarm light is activated and the RUN/STOP light changes
from green to flashing red.
When an Alarm condition occurs:
1
Press to silence any optional audible or
visual alarm. The RUN/STOP light changes from flashing
red to steady red.
2
Note any indicator lights or error messages to
help determine the cause of the problem.
3
Find the alarm or error code in the diagnostics
tables in the Troubleshooting section of this manual.
4
If the unit is still operating, press
the alarm and shut down the Thermolator to correct the
problem.
5
Run
Press to resume normal operation after
the problem is corrected.
