Service plan
The built-in service timer will give a Service warning message after a preprogrammed time interval has
elapsed.
.
Consult your supplier if a timer setting has to be changed. See section
Calling up modifying service timer
. The intervals must not exceed the nominal intervals and must coincide logically.

Explanation
ARAVF
Power recovery
time
Is the period within which the voltage must be restored to have an automatic restart. Is
accessible if the automatic restart is activated. To activate the automatic restart function,
consult your supplier.
Restart delay
This parameter allows to programme that not all compressors are restarted at the same
time after a power failure (ARAVF active).
Compressor
element outlet
The regulator does not accept inconsistent settings, e.g. if the warning level is
programmed at 95 ˚C (203 ˚F), the minimum limit for the shut-down level changes to 96
˚C (204 ˚F). The recommended difference between the warning level and shut-down
level is 10 ˚C (18 ˚F).
Delay at shut-
down signal
Is the time for which the signal must exist before the compressor is shut down. If it is
required to program this setting to another value, consult your supplier.
Minimum stop
time
Once the compressor has automatically stopped, it will remain stopped for the minimum
stop time, whatever happens with the net air pressure. Consult your supplier if a setting
lower than 20 seconds is required.
