Ripple in the DC auxiliary voltage
Adjust the binary input threshold voltage correctly. It is recommended
to set the threshold voltage to 70% of the nominal auxiliary voltage.
The factory default is 16 V to ensure the binary inputs' operation
regardless of the auxiliary voltage used (24, 48, 60, 110, 125, 220 or
250 V DC). However, the default value is not optimal for the higher
auxiliary voltages. The binary input threshold voltage should be set as
high as possible to prevent any inadvertent activation of the binary
inputs due to possible external disturbances. At the same time, the
