The V40 flowmeters can be connected to the terminals S13 / IMP1 to S15 / IMP3
and GND (either polarity).
Connect the irradiation sensor CS10 to the terminals CS10 and GND with cor-
rect polarity. To do so, connect the cable marked GND to the GND common ter-
minal block, the cable marked CS to the terminal marked CS10.
The terminals marked PWM / 0-10 V are control outputs for high-efficiency pumps
(for connection see illustration).
Electrical connection of a high-efficiency pump (HE pump)
Speed control of a HE pump is possible via a PWM signal / 0-10 V control. The pump
has to be connected to the relay (power supply) as well as to one of the PWM out-
puts of the controller. In the Output adjustment channel one of the PWM control
types as well as a relay have to be selected (see page 16).

Note
When Grundfos Direct Sensors
TM
are used, connect the sensor ground
common terminal block to PE.
Connect the analogue Grundfos Direct Sensors™ or FRH humidity sen-
sors to the Ga1 and Ga2 inputs.
Connect the digital Grundfos Direct Sensors™ or FRHd humidity sensors
to the Gd1 and Gd2 inputs.
Connect the flow rate sensor with frequency signal to the FR1 input.
The controller is supplied with power via a mains cable. The power supply of the
device must be 100 … 240 V~ (50 … 60 Hz).
Connect the mains cable to the following terminals:
Neutral conductor N
Conductor L
Protective earth conductor
⏚
(common terminal block)
WARNING!
Danger of electric shock!
L' is a fused contact permanently carrying voltage.
Î
Always disconnect the device from power supply
before opening the housing!
Conductor L' (L' is not connected with the mains cable. L' is a fused contact
permanently carrying voltage.)
Note
For more details about the commissioning procedure see page 9.
