7.2.1 Process messages
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
memory.
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 chapter
7.3 - "Service contact").
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.
