Application and Setting Notes
Parameter: Binary Inputs > Binary Inputs Config > Operate Voltage
•
Default Setting: Range 1: 24 V/48 V/60 V
This setting selects the binary input DC operate voltage. This is applied to all binary inputs. See perform-
ance specification/technical data for pickup voltage, drop-off voltage and voltage withstand levels.
Parameter: Inverted Input
•
Default Setting: <None>
When assigned as inverted the selected binary input picks up on loss of operate voltage and resets
when the operate voltage is applied. Inversion occurs before the pickup and drop-off time delays are
applied.
Parameter: Pickup Delay
•
Default Setting: 0.02 s
Each binary input can be independently set to operate after the operate voltage is applied plus a time
delay. The inputs have a default pickup delay setting of 20 ms which provides security against operation
in the presence of AC voltage across the input terminals e.g. induced AC voltage on cross site wiring
connections. Where the application requires instantaneous operation the pickup delay can be set to 0.
Parameter: Drop off Delay
•
Default Setting: 0 s
Each binary input can be independently set to reset after the operate voltage is removed plus a time
delay.
