First, remember to demount the connectors with hazardous voltages.
Picture 1: Detach the device from the DIN rail by lifting the bottom lock.
Section 3.2 - When front LED lights red / display shows AO.ER
Omega DRST-UR is designed as a SIL 2 device with a high safety level. Therefore, a continuous measurement
of the outgoing current is carried out on a 4...20 mA and 20...4 mA output signal. If the current output signal is
different from the internal calculated output value or the current output is 0 (due to e.g. an open circuit breakage),
an error mode switches on the red front LED and disables the relays. This function is not a default option but must
be actively selected via the programming menu (S4-20 & S20-4).
The error mode can only be reset by switching off and then switching on the supply voltage to the device.
