Wilo – switching plug 3~230 V three-phase current
3 230 V 3 400 V
Wilo-DKG-II Rotational monitoring/service unit
Retrofittable plug for Wilo-TOP-S/-SD/-Z
three-phase pumps for connecting the
pump motor to the existing 3~230, 50 Hz
supply voltage.
Weight: approximately 30 g.
>Function
Adapting the pump for connection to 3~230 V
is made easy by simply replacing the
standard-series 400 V speed/voltage plug
in the pump terminal box with the 230 V
switching plug provided (accessory).
This retrofit does not allow the pump to be
connected to 1~230 V.
No additional wiring work is required.
Manual variable speed control with the plug
is retained for 3 stages.

Wilo service device with expanded function
for electronic, non-contact
- checking of the precise direction of rotation
(glanded and glandless pumps) and
- testing for possible pump standstill
(standard glandless pumps in single- or
three-phase versions).
Measurement takes place during operation
as a basic principle. It is no longer necessary
to switch the pump motor on and off briefly.
Device includes 9V battery (commercially
available) and testing directions.
Solar thermal
>Function
Three integrated, high-sensitivity sensors
measure the stray field of the pump motor
when the service device is loaded. Based on
the time sequence of the sensor signals, the
electronics determines
- the direction of rotation and
- the rotation of the pump rotor, and this the
conveyance of the fluid through the pump.
Red and yellow LEDs signalise rapidly and
clearly disrupted/undisrupted pump operation.
