At input “ IN2 ” a suction pipe with low level signal can be connected. In low level condition the
contact is open.
At the Ecoplus
When using the system w/o the low level option, a wire link must be connected at “
IN2 ”.
-V units the capsule switch has to be connected to “ IN2 ”
4.6.2 Enable signal
Metering is only activated when contact at “ IN1 ” is closed (e.g. pressure switch). When
unit is used w/o this option a wire link must be connected at “ IN1 ”.
Electrical connection of different Enable-modules see Chapter 5.3.
