Using.the.4.–.20.mA.set-point.value.input
If several devices of Type EP 501 / EP 501 C are connected in series and the power supply to a device in
this series connection fails, the input of the failed device becomes highly resistive.
As a result, the 4 – 20 mA standard signal fails.
In this case please contact EBRO Service directly.
