Protrol IPC4020 Manual page 38

On this tab, the current status of the following is displayed:
▪
Indications - the status of each LED is mirrored
▪
Temperature - measured inside the device and displayed with an offset of -15 degrees in standard
design. E.g., if the unit measures 43 degrees, the value 28 is displayed
▪
Current values, primary values
o Phase currents and residual current
o Max fault current
o Max current of indicator - resets with the Send max clear unit button
o 15 minutes mean value of minimum phase current
▪
Faulty phase(s) for last registered fault
▪
Current time - RTC time
The Send ACK to unit button works just like the physical button on the device. Note that the value Max is
not reset.
Site manager is typically used to check the device status via the Ethernet interface and in conjunction with
commissioning to obtain current values. A good way to verify that all phase currents are correctly
connected is, for example, to read the amplitudes. If they are equal and the sum current at the same time is
small, the connection is likely to be correct.
There is a checkbox that enables activation of the outputs via the web interface. It is checked as long as you
are logged in. To activate an output, simply click on the LED symbol. It then lights up and closes the relay
output for 2 seconds.
