Problem: The heating hopper heater thermal safety
switch has opened due to an overheat condition.
Located on the top of the Heater Tube is a Temperature Safety
Switch. If the temperature of the 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 and locate the Heater Tube Safety Switch on the upper side of
the stainless-steel heater tube. Press the red safety switch button to
reset the Temperature Safety Switch. If problem occurs repeatedly,
contact Maguire Technical Support.

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 and locate the purge heater thermal safety switch on the side of
the stainless-steel purge heater tube. Press the red reset button to

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.
