Service plan
The built-in service timer will give a Service warning message after a preprogrammed time interval has
elapsed.
Also see section Maintenance schedule .
Consult your supplier if a timer setting has to be changed. See section Modifying general settings . The
intervals must not exceed the nominal intervals and must coincide logically.
Terminology
Term Explanation
ARAVF Automatic restart after voltage failure. See section Controller
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.
