Shutdown and alarm acknowledgement

F4
A compressor shutdown is acknowledged by pressing /RESET. If the cause of shutdown is no lon-
ger present the shutdown message will disappear from the shutdown queue. A shutdown stops the com-
pressor immediately and is indicated by quick red flashes in the light diode above the start key. An
acknowledged shutdown where the shutdown cause is still present is indicated by slow red flashes in
the light diode.
A compressor alarm is automatically acknowledged when the alarm cause is no longer present and the
alarm message will disappear from the alarm queue. An alarm does not stop the compressor. It is indi-
cated by quick yellow flashes in the light diode above the start key.
