Connecting The Flow Sensor - DWT WaCS PWM Serie Instrucciones De Instalación Y Mantenimiento


Attach connector 8 of J5 on the 1st inverter to connector 7 of J5 on the 2nd inverter. Repeat the
operation for all inverters in the chain (use the shielded cable).

Wire in a jumper between connector 8 and 10 of J5 on the last inverter to close the chain.
Figure 9 provides the wiring diagram for this procedure.

Caution: always use shielded cable to connect the sensors.
To enable use, the current pressure sensor must be configured via software, parameter PR in
the installer menu; refer to paragraph 6.5.7. Otherwise the unit may not run, with error BP1
(pressure sensor not connected).
2.2.3.2

Connecting the flow sensor

The flow sensor is supplied with its own cable. One end of the cable must be connected to the sensor and
the other end to the relative inverter flow sensor input, marked "Flow 1"; see Figure 7.
The cable has two different terminals with compulsory direction of insertion: connector for industrial
applications (DIN 43650) on the sensor side and 6-pole connector on the inverter side.
The body of the flow sensor and ratiometric pressure sensor (0-5V) have the same type of
DIN 43650 connector, and therefore take care to ensure that the correct sensor is connected
to the correct cable
