The output connector is used for connecting the accessories. Namely the accessories are:
- Level probe (level switch)
- Flow sensor
It is very important to disconnect the power from the pump when connecting the accessories.
3.3 INPUT/OUTPUT EXTERNAL CONNECTIONS (FOR EXTERNAL ACCESSORY)
It is also very important to protect the unutilized connectors with male connectors supplied with the pump.
Such operation will protect the internal circuitry from unwanted shorts and/or the power surge either from the
operator or from different sources. There will be no accessible contacts after installation is completed.
It is imperative that the accessories will be supplied by the factory to avoid unwanted mismatched situations
and/or furthed possible damage (wich in this case will be no covered by the warranty).
Further more cables and accessories must be suitable and rated for the proper voltage and type of insulation.
SUMMARY OF TYPE OF CONNECTIONS
1. INPUT LEVEL SWITCH: the pins #3-4 of the connector in position #2 are dedicated to the operation of the
level sensor. Such operation is activated by a float containing one magnet if the liquid is below the position or
completely absent the flow will slide down activating a reed switch.
2. INPUT FLOW SENSOR: the pins #1-2 of the connector in position #2 are dedicated to the operation of the
flow sensor.
