Description

Electric control and protection panel of electric pumps installed in pumping systems for hydropressors with 2 electric pumps.
Alternation of work regimes in electric pumps, with visual and audible alarm.
Pre-programmed water wait timer.
Reinforcement timing for support pump input.

Applications

Against lack of water.

Excessive motor consumption (thermal trigger).

Control circuit protection via circuit breaker.

Operation

After verifying the correct connection of the entire wiring, the motor circuit breakers must be adjusted according to the nominal intensity of the motors.

Check the operation of the pumps by turning the control selector to the Manual () position.

For Automatic operation, set the selector to Automatic (A).

During each actuation of the signal of the Alternation pressure switch, switch Pump 1 or Pump 2 alternately.

If during the actuation of the Alternation pressure switch, an action of the Reinforcement pressure switch appears, the second available Pump will turn on.

The Pumps turn off respectively when the Boost pressure switch signal and the Alternation pressure switch signal stop working.

When the minimum contact is switched off, the two pumps are switched off and the alarm output is switched on.

The alarm is canceled when the liquid level or pressure is reset.
