Fault description
Possible cause
Required measures
General
Chamber permanently turned
off.
No power supply.
Check connection to power supply.
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.
Pressure threshold of 100 mbar
not reached. No heater release.
Wait until pressure threshold is
reached and heater released.
Select suitable pressure setpoint.
Chamber door not properly
closed.
Completely close chamber door.
Door gasket defective.
Replace door gasket,
Pt 100 sensor defective.
Contact BINDER service.
Heating element defective.
Semiconductor relay defective
Chamber doesn’t heat up.
Alarm message „safety control-
ler“ 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. Ack-
nowledge the alarm on the control-
ler. Check the settings of the tem-
perature setpoint and safety con-
troller value. If appropriate, select
suitable safety controller value
(chap. 14.2).
Safety controller defective.
Contact BINDER service.
Chamber doesn’t heat up.
Alarm message “Overtempera-
ture” on the controller display
Safety temperature limiter (TL)
has turned off the hea-
ter.Chamber defective.
Let the chamber cool down. Ack-
nowledge the alarm on the control-
ler and restart the chamber
(reconnect power plug). 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
Pt 100 sensor defective.
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 mea-
sured during calibration
Reference temperature sensor
has insufficient contact to expan-
sion rack.
Fix the reference temperature sen-
sor 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.
