opened due to an overheat condition.
Located on the side of the purge heater tube is a Temperature Safety
Switch. If the temperature of the purge heater exceeds the safety
switch maximum, this switch opens, shutting down the entire dryer
(FATAL Alarm).
Solution: Allow the dryer to cool. Open the left side panel of the dryer

VC MISSING
ALARM:18
Problem: The Vacuum Chamber is missing.
If Vacuum Chamber load cell is reading 33 pounds (15000 grams)
below tare during AUTO run, this alarm is triggered and Dryer stops
(fatal). This alarm is generally caused by a missing Vacuum Chamber
but may also be caused by the dryer Vacuum Chamber load cells
having been zero calibrated while material was in the Vacuum
Chamber.
Solution: If Vacuum Chamber is missing replace Vacuum Chamber. If
Vacuum Chamber is in place, ensure the tank is empty and zero
calibrate the load cells. If load cells are damaged, a zero calibration
may detect this.
RH MISSING
ALARM:19
Problem: The Retention Hopper is missing.
If Retention Hopper load cell is reading 23.2 pounds (10000 grams)
below tare during AUTO run, this alarm is triggered and Dryer stops
(fatal). This alarm is generally caused by a missing Retention Hopper
but may also be caused by dryer Retention Hopper load cells having
been zero calibrated while material was in the Retention Hopper.
Solution: If Retention Hopper is missing replace Retention Hopper. If
Retention Hopper is in place, ensure the hopper is empty and zero
calibrate the load cells. If load cells are damaged, a zero calibration
may detect this.
