8.0 INPUT/OUTPUT EXTERNAL CONNECTIONS (FOR EXTERNAL ACCESSORY)
As shows on paragraph 3.3 the three connectors are used for connecting the accessories.
Namely the accessories are:
- Level control switch;
- Water meter input (Reed switch type);
- Output service relay
It is very important to disconnect the power from the pump when connecting the accessories. 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 idoneus and rated for the proper voltage and type of insulation.
SUMMARY OF TYPE OF CONNECTIONS
1. INPUT LEVEL SWITCH: as shown on paragraph 3.3 the pins #3-4 from 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.
3. INPUT FROM WATER METER: our pump (pins #3-4 from position 3) can be connected to a water meter generating
reed switch signal proportional to a certain quantity of water passing through out. It must be clear that such
signal are only of ohmic nature and they do not carring any power.
Connecting to the pump a different type of water meter generating any voltage will irrevocably damage the
pump thus avoiding any warranty.
4. OUTPUT SERVICE RELAY: such relay utilize the pins #1-3 (connecctor #1 paragraph 3.3) wich are
activated in case of alarm status.
