The device has been developed with a high level of safety. Therefore, a continuous
measurement of the output current takes place at the 4...20 mA output signal. When
the current is 0 mA, the device switches to error mode and the LED indicator lights
red. This function is not a standard option, but must be actively selected in the menu.
The error mode can only be reset by switching the power supply of the device off and
on again.
