Pressure Transducer (cable 2)
A pressure transducer is needed, when the module
is set to closed loop pressure control (TYPE = Q)
or if the circuit requires a internal or external horse
power control.
The pressure transducer must be connected to the
power supply (connector PIN 3 to +24 V), to the
pressure transducer signal input (connector PIN 1
to module PIN 14) and to the module 0 V level (con-
nector PIN 2 to module PIN 9 / 11). The pressure
transducer signal is between 4 mA (current signal)
at 0 bar and 20 mA at the transducers nominal pres-
sure of 600 bar. The normal working range in case
of a PV series pump is 4...11.67 mA (0…350bar).
The connection to the pressure transducer is
checked by the modules cable break monitoring.
A current below 3 mA will lead to a shut off of the
