The main board of the climatic chamber includes a lithium cell. Please dispose of it according to national
regulations.
The refrigerant used R 134a (1,1,1,2-tetrafluorethane) is not inflammable at ambient pressure. It must not
reach the environment. Professionally suck the refrigerant off the refrigeration cycle and dispose of it
according to the national regulations.

Fault description
Possible cause
Required measures
Heating
Controller defective.
Semiconductor relay defective.
Contact BINDER service.
Chamber heating permanently,
set-point not held.
Controller not well adjusted, or
adjustment interval exceeded.
Calibrate and adjust controller.
Pt 100 sensor defective.
Heating element defective.
Chamber doesn’t heat up.
Semiconductor relay defective
Contact BINDER service.
Limit temperature reached.
Safety controller (chap. 11.2) set
too low.
Let the chamber cool down and
hit RESET button of MB1 control-
ler. If appropriate, select suitable
limit value.
Chamber doesn’t heat up when
turning on the chamber.
Safety controller responds.
Safety controller (chap. 11.2)
defective.
Contact BINDER service.
No power supply.
Check connection to power sup-
ply.
Wrong voltage.
Check power supply for voltage
of 115V or 230V.
Unit fuse has responded.
Check unit fuse and replace it if
appropriate. If it responds again,
contact BINDER service.
Controller defective.
Unit without function.
Nominal temperature exceeded
by 10° due to unit failure. Over
temperature protective device
(class 1) responds.
Contact BINDER service.
Limit temperature reached.
Check setting of temperature set-
point and of safety device class
3.1. If appropriate, select suitable
limit value.
Too much external heat load.
Reduce heat load.
Controller defective.
Safety device defective.
Mechanical safety device class
3.1 responds
(with option safety device class
3.3).
Semi-conductor relay defective
Contact BINDER service.
Limit temperature reached.
Check setting of temperature set-
point and of safety device class
3.2. If appropriate, select suitable
limit value.
Mechanical safety device class
3.2 responds
(with option safety device class
3.3).
Controller or safety device defec-
tive.
Contact BINDER service.
