Chart recorder function: meas-
ured-value memory cleared; in-
formation lost.
New setting of storage rate or scaling
(minimum and/or maximum) (chap.
16.2).
Change the storage rate or
scaling ONLY if the previously
registered data are no longer
required.
Controller does not equilibrate
to setpoints entered in Fixed
value operation mode
Controller is not in Fixed value opera-
tion mode.
Change to Fixed value opera-
tion mode.
Humidity control is turned off.
Turn on humidity control (chap.
6.3).
Controller does not equilibrate
to program set-points.
Controller is not in program operation
mode, or program delay time is run-
ning.
Start the program again. If ap-
propriate, wait for the program
delay time.
Program duration longer than
programmed.
Tolerances have been programmed.
For rapid transition phases, do
NOT program tolerance limits in
order to permit maximum heat-
ing, refrigerating, or humidifica-
tion speed.
Program keeps the last pro-
gram setpoint constant while in
setting “ramp”.
Program line with setting “ramp” is in-
complete.
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”.
Humidity alarm when operating
without water connection.
Humidity control turned on.
Turn off humidity control (chap.
6.3).
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.
Alarm message:
- - - - or <-<-< or >->->
Sensor rupture between sensor and
controller or Pt 100 sensor defective.
Contact BINDER service.
Short-circuit.
Miscellaneous

Remove calcifications by citric
acid or acetic acid solutions
(chap.
