Swimming Pool Frame with Differential Switch

Swimming Pool Control Control and protection of electric pumps used in swimming pool water circulation systems.

Presentation
Gray ABS box 250x200x110 mm and lid with transparent polycarbonate window.
WEG contactor and motor-circuit breaker.
Clock with reserve for automatic control of the electric pump.
3 operating positions: automatic, manual or off.
Protection against overloads and short circuits through circuit breaker.
Protection against fault current >30mA through differential switch.
Green LED for engine on indication.
Red LED for circuit breaker-motor off indication.
Yellow led to indicate the frame in automatic operation.
Connection cable glands.

How it works
After making all the connections of the electrical cables correctly, the circuit breaker must be adjusted according to the nominal current of the motor.

The switchboard must have all signals turned off until the switch of the command circuit is switched to the automatic position (AUT), at which time the yellow LED on the signaling module turns on.

In the automatic operation position (AUT) the pump turns on (green LED on the signaling module) within the period of time set on the time switch.

With the switch in the manual position, the pump turns on regardless of the time switch setting.

Opening the safety command turns off the pump, regardless of the status of the switch and the time switch.

Tripping of the circuit breaker due to overload (red LED on the signaling module) switches off the pump, regardless of the status of any of the commands.
