Data communication / Bus
the controller is equipped with the
VBus
®
for data
transfer with and energy supply to external modu-
les. the connection is carried out at the two termi-
nals marked VBus and GnD (any polarity).
the terminals s13 to s15 can be used as impulse in-
puts for V40 flowmeters or as inputs for Fs08 flow
switches.
V40 flowmeters can be connected to the terminals
s13 / V40 to s15 / V40 and GnD (either polarity).
Connect the irradiation sensor
CS10
to the termi-
nals Cs10 and GnD with correct polarity. to do so,
connect the cable marked GnD to the GnD common
terminal block, the cable marked Cs to the terminal
marked Cs10.
The terminals marked
pWm are control outputs for
high-efficiency pumps.
In the In-/outputs menu, relays can be allocated to
the pWm outputs.
Connect the
FlowRotor
to the input marked Flow-
rotor.
Connect the
analog Grundfos Direct Sensors
™ to
the inputs GDsa1 and GDsa2.
Connect the
digital
Grundfos Direct Sensors
™ to
the GDsD1 and GDsD2 inputs.
the controller is supplied with power via a mains
cable. the power supply of the device must be
100 ... 240 V~ (50 ... 60Hz).
the
mains connection
is at the terminals:
neutral conductor n
Conductor l
Conductor l' (l' is not connected with the mains
cable. l' is a fused contact permanently carrying
voltage)
protectiv earth conductor (common terminal
block)
Note:
For more information about accessories,
see page 80.
WARNING!
Electric shock!
l‘ is a fused contact permanently
carrying voltage
Î
Always disconnect the
controller from power supply
before opening the housing!
