Type of error
Possible reason
Correction
Mains power failure
A mains power failure will be
detected if the power supply is
interrupted under normal conditions
(run mode).
The process will continue once
the mains power is available
again. The process times will be
reset to zero. The set control
values will be preserved.
Factory settings loaded
All parameters are reset to the
delivery status of the system.
The factory settings will be loaded
if the corresponding menu
command is executed in the
service menu or if an error
occurred in the parameter menu.
No rotor detected
(only Triple TMM)
Check the rotor for correct
installation.
If the error occurs again, contact
the after-sales service (see 7.2)
Nominal rotor speed not
reached
After two minutes, the rotor has still
not reached 90% of its nominal
speed.
- set speed is too high
- drive moves sluggishly
Check the set speed.
When the rotor is at a standstill
and the system is switched off,
check whether the drive moves
sluggishly, by hand. Contact the
after-sales service (see 7.2)
Safety pressure not reached
The safety pressure inside the rotor
chamber must be reached within 5
minutes after the start of an
evaporation process.
Check whether the value that
was entered for the safety
pressure is not too low. Check
the components for any possible
leaks.
Ice condenser temperature not
reached
Only if the "Cooling trap control"
option is enabled:
The ice condenser temperature
must be -25°C.
If the temperature is not
reached, the heater will be
deactivated.
