Section 3 - How to demount DRST-AC
Picture 1:

When front LED flashes red or DRSL-DISPLAY display shows AO.ER
The DRST-AC is designed with a high safety level. Therefore, the device continuously
measures the output current. If “S4-20” is selected during configuration, and output
current drops to 0 mA, the DRSL-DISPLAY display will indicate “AO.ER” and the
front LED will turn red. (A 0 mA output can be caused by an open output loop). The
error mode can be reset by power cycling the device or stepping through the menu.
