DIP switches
DIP switch
Function
DIP switch 1:
Inversion of the input signal
See figure "Curve".
DIP switch 2:
Inversion of the output signal
See figure "Curve".
DIP switch 3:
Activation of the overrun function
The overrun function reduces the number of switching
processes for high-efficiency pumps. The power supply
of the pumps remains switched on for 20 min after the
input signal has signalled a switch-off.
DIP switch 4:
Conversion of the 0-20 mA output to a 4-20 mA
output
This DIP switch is used for converting the output signal
at the 0-10 mA output to 4-20 mA.
