Fault description
Possible cause
Required measures
Controller
No chamber function
(dark display).
Chamber is in standby mode.
Deactivate standby mode (chap.
6.2).
Menu functions not available.
Menu functions not available with
current authorization level.
Log in with the required higher
authorization.
MB2 controller:
Log in with the
required higher authorization. or
contact BINDER service to obtain
an activation code (chap. 9.2.6).
No access to controller
Incorrect password.
Contact BINDER service.
Controller does not equilibrate
to entered setpoints.
Temperature control is turned off
Turn on temperature control (chap.
8.5).
Pressure control is turned off.
Turn on pressure control (chap.
8.6).
MB2 controller: Set-points were
entered in Fixed value operation
mode. Controller is in program
operation mode.
Change to Fixed value operation
mode.
Pressure alarm when operating
without a vacuum connection.
Pressure control turned on.
Turn off pressure control (chap.
8.6).
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.
MB2 controller: Measured-value
memory cleared in Chart
recorder function, information
lost.
New setting of storage rate or
scaling (minimum and/or
maximum) (chap. 21.2).
Change the storage rate or scaling
ONLY if the previously registered
data are no longer required.
MB2 controller: Program operation
Controller does not equilibrate
to program set-points.
Controller is not in program
operation mode, or program
delay time is running.
Start the program again. If
appropriate, 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 heating,
evacuating, or ventilation 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”.
