Description
Power consumption
Threshold voltage
Reaction time
Adjust the binary input threshold voltage correctly. The threshold
voltage should be set 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
threshold should be set so that the correct operation is not jeopardized
in case of undervoltage of the auxiliary voltage.
