Setting the Overvoltage Alarm Value: V-O (Voltage Over)
If the Down Key ( ) is pressed from the undervoltage alarm value setting dis-
play (V-U), the display will switch to the overvoltage alarm value setting dis-
play (V-O).
Note If the voltage exceeds the SV for 80 ms, the Alarm Output (ALM) will be
turned OFF and the seven-segment display will alternate between error code
A20 and the measured voltage.
The alarm output can be cleared after the voltage falls below the SV
−0.3 V for
more than 500 ms.

The setting range is 20.0 to 28.8 V (0.1 V units).
Note If the or Key is pressed for more than 2 s,
the SV will change in 1.0 V units instead of 0.1 V
units.
Change the SV with the and Keys.

Switch to the
