Problem
Secondary Vacuum Pump
Overload
- If the secondary
vacuum pump exceeds its
full load amp rating or the
overload has tripped due to a
mechanical or electrical
problem the dryer will shut
down.
Possible cause
The vacuum pump current draw has
exceeded the full load amps rating of
the motor.
The vacuum has mechanically failed or
is unable to rotate freely.
The vacuum pump has failed
electrically.
Loss of phase of power to the motor
starter.
The overload is set incorrectly.
The overload is defective.
Solution
Press alarm acknowledge and allow the
overload to reset then try to restart the
dryer. If the alarm condition occurs
again have a qualified electrician check
the current draw to the motor.
Disconnect and lock out main power.
Check the vacuum pump for mechani-
cal failure and free rotation. Replace if
necessary. Allow the overload to reset
then try to restart the dryer.
Disconnect and lock out main power.
Check the vacuum pump for electrical
shorts or open circuits. Replace if nec-
essary. Allow the overload to reset
then try to restart the dryer.
Check for a blown fuse in the dryer or
main power supply. Allow the overload
to reset then try to restart the dryer.
Disconnect and lock out main power.
Check the overload settings and con-
firm that the settings match the full
load amps listed on the vacuum pump
motor. Allow the overload to reset then
try to restart the dryer.
Replace the overload.
Passive Alarms
If an alarm occurs, a red dialog box is displayed on the dryer’s touch screen
control. The dryer continues to operate, but this problem could prevent cor-
rect drying of your material. The dialog box will indicate whether the alarm
is a shut down alarm or a passive alarm.
