RELAYS
The E30 houses 2 relays. Both relays are SPST with normally open
contacts. Relay 1 is normally regarded
as the pump control relay and
relay 2 is normally regarded as the alarm relay. When operating the E30
as a dual pump controller, relay 2 is used to control the second pump.
With the HD terminal linked to the NO terminal of Relay 1, the E30
can directly control a single phase motor up to 2.4kW. Without the
HD terminal link in place, relays 1 & 2 are limited to directly
controlling a motor to 0.75kW. Both relays can control motors of
any size via interposing contactors.
