Adjust the binary input threshold voltage correctly. The threshold voltage
should be comparable to the nominal value instead of the default
minimum value. 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
threshold should be set so that the correct operation is not jeopardized
in case of undervoltage of the auxiliary voltage.
