Type 3360, 3361
Installing the valve
Use of set-point input 4...20 mA
If several Type 3360, 3361 devices are connected in series
and the electrical power supply for a device in this connected
series fails, the input of the failed device becomes highly
resistive. As a result, the 4...20 mA standard signal fails.
Choice of connection line:
When choosing the length and cross-section of the indi-
vidual wires, take into account the voltage drop in relation
to the maximum supply current.
