troller display working.
Timer run off.
Re-program the timer or turn it off.
Defective semiconductor relay.
Contact BINDER service.
Defective controller.
Chamber doesn’t heat up. Alarm
message “Overtemperature” is
displayed.
Overtemperature protective
device class 1 (thermal switch)
activated.
Proceed as described in chap.
13.1. If appropriate, contact
BINDER service.
Chamber doesn’t heat up. Alarm
message “Safety contr. class 3.1”
is displayed.
Safety controller class 3.1 has
responded.
Check the settings of the tempera-
ture set-point and of the safety de-
vice class 3.1 (chap. 13.2).

Chamber doesn’t heat up. Alarm
message “Safety contr. class 2” is
displayed.
Safety device class 2 has
turned off the chamber.
Let cool down the chamber. Check
the settings of the temperature set-
point and of the safety device class
2 (chap.
13.2). If appropriate, select
suitable limit value.
Safety controller defective.
Contact BINDER service.
Deviations from the indicated
heating-up times.
Chamber fully loaded.
Load the chamber less or consider
longer heating-up times.
Controller
No chamber function
(dark display).
Display in standby mode.
Press on touchscreen.
Main power switch turned off.
Turn on the main power switch.
Menu functions not available.

Chart recorder function: meas-
ured-value memory cleared; in-
formation lost.
New setting of storage rate or
scaling (minimum and/or maxi-
mum) (chap. 17.2).
Change the storage rate or scal-
ing ONLY if the previously regis-
tered data are no longer required.
Controller does not equilibrate to
setpoints entered in Fixed value
operation mode
Controller is not in Fixed value
operation mode.
Change to Fixed value operation
mode.
Controller does not equilibrate to
program set-points.
Controller is not in program oper-
ation mode, or program delay
time is running.
Start the program again. If appro-
priate, wait for the program delay
time.
Program duration longer than
programmed.
Tolerances have been pro-
grammed.
For rapid transition phases, do
NOT program tolerance limits in
order to permit maximum heating
or refrigerating speed.
Program keeps the last program
setpoint constant while in setting
“ramp”.
Program line with setting “ramp”
is incomplete.
When programming with setting
“ramp”, define the end value of
the desired cycle by adding an
additional section with a section
time of at least one second.
Ramp temperature transitions
are only realized as steps.
Setting “step” has been selected. Select setting “ramp”.
Acknowledging the alarm does
not cancel the alarm state.
Cause of alarm persists.
Remove cause of alarm. If the
alarm state continues, contact
BINDER service.
