Fault description
Possible cause
Required measures
General
Chamber without function.
No power supply.
Check connection to power sup-
ply.
Check whether the chamber is
turned on at the main power
switch.
Wrong voltage.
Check power supply for correct
voltage (chap. 4.4).
Chamber fuse has responded.
Check chamber fuse and replace it
if appropriate. If it responds again,
contact BINDER service.
Controller defective.
Contact BINDER service.
Nominal temperature exceeded
by 10° due to chamber failure.
Over temperature protective de-
vice (class 1) responds.
Heating
Chamber heating permanently,
set-point not maintained.
Controller defective.
Contact BINDER service.
Semiconductor relay defective.
Controller not well adjusted, or
adjustment interval exceeded.
Calibrate and adjust controller.
Chamber doesn’t heat up.
Pt 100 sensor defective.
Contact BINDER service.
Heating element defective.
Semiconductor relay defective
Chamber doesn’t heat up when
turned on.
Safety controller responds.
Inner chamber temperature has
reached the safety controller set-
point. Safety controller set too
low.
Acknowledge the alarm on the
controller. Check temperature set-
point setting. If appropriate, select
suitable safety controller setpoint
(chap. 12.2).
Safety controller (chap. 12.2) de-
fective.
Contact BINDER service.
Mechanical safety device class
3.1 responds
(with option safety device class
3.3).
Limit temperature reached.
Acknowledge the alarm on the
controller. Check setting of tem-
perature set-point and safety de-
vice class 3.1. If appropriate, se-
lect suitable limit value.
Too much external heat load.
Reduce heat load.
Controller defective.
Contact BINDER service.
Safety device defective.
Semi-conductor relay defective
Mechanical safety device class
3.2 responds
(with option safety device class
3.3).
Limit temperature reached.
Acknowledge the alarm on the
controller. Check setting of tem-
perature set-point and safety de-
vice class 3.2. If appropriate, se-
lect suitable limit value.
Controller or safety device defec-
tive.
