Wrong voltage.
Check power supply for voltage of
115V or 230V.
Chamber fuse has responded.
Check chamber fuse.
Controller defective.
Contact BINDER Service.
Heating
Chamber doesn’t heat up.
Pt 100 sensor defective.
Contact BINDER service.
Heating element defective.
Semiconductor relay defective
Chamber doesn’t heat up.
Alarm message “Safety
controller” on the controller
display
Safety controller has responded:
Inner chamber temperature has
reached the safety controller
value. Safety controller value set
too low or temperature set-point
too high, or error in the heating
system.
Let the chamber cool down.
Acknowledge the alarm on the
controller. Check the settings of the
temperature setpoint and safety
controller value. If appropriate,
select suitable safety controller
value (chap. 11.2).
Safety controller defective.
Contact BINDER service.

Alarm message
“Overtemperature” on the
controller display
Overtemperature protective
device class 2 (thermal switch)
activated. Error in the heating
system.
Let the chamber cool down.
Acknowledge the alarm on the
controller and restart the chamber.
If the error repeats, turn off the
chamber and contact BINDER
service.
Set-point temperature is not
reached after specified time.
Chamber door not properly
closed.
Completely close chamber door.
Door gasket defective.
Replace door gasket,
Controller not adjusted.
Calibrate and adjust controller.
Chamber heating permanently,
set-point not maintained.
Controller defective.
Contact BINDER Service.

Semiconductor relay defective
Controller not adjusted.
Calibrate and adjust controller.
Deviations from the indicated
heating-up times.
Oven fully loaded.
Charge the oven less or consider
longer heating-up times.
Deviations from the
temperature set-point in
equilibrated state.
Invalid calibration
Use the delivered expansion racks
only. Do NOT change between
aluminum and stainless-steel racks
Wrong temperature value
measured during calibration.
Reference temperature sensor
has insufficient contact to
expansion rack.
Fix the reference temperature
sensor with thermal conductive
paste or adhesive aluminum tape.
Leakage current when using a
thermo element not electrically
isolated.
Mount a thermo element electrically
isolated from the rack.
Vacuum
Vacuum not held.
Door gasket defective.
Replace door gasket,
