If error Er 1 occurs during ongoing permeate production (pressure switch minimum pressure of
high-pressure pump), the system attempts a restart at the following intervals:
5 ... 10 ... 20 ... 40 ... 80 ... 160 minutes
If sufficient pressure is present, permeate is produced until the pressure switch for operational
release responds and the error is acknowledged automatically.
During the wait time between the start attempts, the symbol is flashing in the display.

Reaction to return of
power for error Er 0
(power failure > 5
minutes)
0 ... 2
0 = Irrespective of whether the system was
switched on or off prior to the power failure,
it remains switched off after power is re-
stored and error Er 0 is emitted (symbol
is still switched on)
1 = Error Er 0 is deactivated
2 = After power is restored, the system is
switched on or off like prior to the
power failure, and error Er 0 is emitted
D. 15
Run time of work-
shop mode [minutes]
15 ... 99
In workshop mode, permeate is produced
for this time at a 24 h interval after the sys-
tem is switched on. Operation is irrespec-
tive of the status of the pressure switch for
operational release.
