2- StORAGE AND tRANSPORt

This product should be stored in its original package at temperatures between -15°C and + 50°C.

3- DEvIcE uSAGE

The Pump Protector - DRP is an innovative electronic device that guarantees optimal protection of the

submerged pump from dry running, overload, high voltage, low voltage, too frequent starts/stops, phase

imbalance, phase loss (3-phase).

The different models available are:

DRP version 2.0 - BLuE:

single-phase 220-240V ZDs motors “2-wire” (up to 1,5 kW); single-phase ZDs

motors “3-wire PsC” (up to 1,5kW); single-phase Franklin PsC motors (up to 1,5 kW).

DRP version 3.0 - BLuE:

single-phase 220-240V ZDs motors “3-wire PsC” (2,2kW) and single-phase

Franklin PsC motors (2,2 kW).

DRP version 3.0 - RED:

Three-phase 380-415V ZDs & Franklin motors (up to 4 kW) and three-phase

220-240V Franklin motors up to 2,2kW.

Nb! None of the DRPs can be used with a frequency inverter.

Please be aware that the single-phase 2,2 kW (Version 3.0 – blue) and all three-phase DRPs (version 3.0

– Red) must ONLY be used with the appropriate motor. The DRPs are adjusted at the factory and must

not be exchanged later with another motor (even if it is the same kW). Unless you have been certified by

ZDs srl. and installed proper testing equipment, the warranty is void if the DRP has been used with another

motor than the one supplied with the DRP from the factory. The serial numbers of both motors and DRPs

are kept at the factory and recorded at the time of despatch.

The DRP units are fitted to a short length of cable attached to the motor so that when the pump is installed

in the borehole, well or tank, the DRP is located just above the pump-section. For all O2 motors and O3

motors to 1,1kW the cable from the connector of the motor to the sensor is 115cm. For 1,5kW O3 motors

the cable length from the connector of the motor to the sensor is 150cm and for 2,2kW O3 motors the

cable from the connector of the motor until the sensor is 180 cm. For OT motors the different lengths are:

0,37kw the length is 0.7mt, 0,55kw length is 0.8mt, 0,75kw length is 0.95mt , 1,1kw length is 1.2mt,

1,5kw length is 1.48mt, 2,2kw the length is 1.75mt , 3kw length is 2.17mt and for 4kw the length is

2.17mt. The normal cable to supply the pump is connected to the DRP connection; this means that no

extra cable is required, unlike traditional probes.

Insulation test with DRP (can it be “meggered”?)

The DRP can be meggered up to 500V, please connect the terminal of the megger instrument (negative)

to the earth, the other to the black cable, then repeat the same operation with the grey cable and last with

the brown cable. The negative cable of the DRP must always be connected to the earth.

Dry Running Protection (All versions)

For correct operation both the complete motor and DRP must be completely submerged in

the water. When testing the DRP please be aware that the motor and DRP must be put in

the same tank of water. Whilst the water covers the sensor, the motor will function normally.

however, when the sensor ceases to be in contact with water, the DRP immediately will stop
