5.3 Function
•
Valve (V1) for ON/OFF of the ejector. This valve is
normally open (NO) or normally closed (NC). The
normally closed (NC) valve behaves as normally
open (NO) if the power is turned off, i.e., the
ejector continues operating.
•
Valve (V1) for ON/OFF is also available as a NC
2 version. The NC 2 valve behaves like a NC
(Normally Closed) even if power to AVM™2 is
turned off.
•
Valve (V2) for ON/OFF of the blow-off function.
•
Option for valve (V2) - automatic blow-off (1
sec), activated immediately after valve (V1) has
changed position.
•
Adjustment valve (V3) for controlling the blow-off
flow.
•
Integrated automatic energy-saving function
(ES) used to minimize the air consumption. This
function can be activated manually or by a signal.
•
Vacuum switch that sends two digital output
signals, S1 and S2. Selection of signal level is
done with a rotary switch, and there are 16 preset
signal levels available.
