RELAY

4.4.7. Relays

There are two relays in the unit:
- Relay 1 only controls the opening of the main valve (high flow rate). A time delay before
activation may be fixed and the operating polarity may be inverted; the user also has the
facility of setting the percentage of the dosage quantity to be delivered through the main
valve (high flow rate). This latter facility implies that Relay 2 controls an auxiliary valve (low
flow rate) in order to provide the remainder of the quantity which was initially set.
- Relay 2 can be configured for three different functions: Alarm, end of dosage and control
of an auxiliary valve. In each configuration the operating polarity can be inverted.
