5.1.6
Electrical inputs
The electrical inputs function is fitted with 2 digital inputs, which can also be used to reset the
Q_low-Timers of the pressure regulation and blocking functions with applicable parameterisation.
Input signals
The signals of electrical inputs 0 and 1 are processed according to the debounce time DI,
Pm.27.4-27.5, and signal extension time DI, Pm.27.2-27.3, parameters. The times are valid for both
channels. The activation of the signal extension is set channel by channel with the signal extension
channel DI0, Pm.27.0, and signal extension channel DI1, Pm.27.1, parameters. The input signals are
provided as electrical input DI0, Em.3.2, and electrical input DI1, Em.3.3.
Status indicators
The status of the electrical inputs is indicated channel by channel by status LEDs. When the LED is lit, a
logic 1 is present at the input, when the LED is not lit, a logic 0.
Sensor supply
The sensor supply voltage U
SEN
is supplied at the connections for the electrical inputs. The sensor
supply voltage U
SEN
is internally protected against short-circuit/overload. The parameter Behaviour
after short-circuit/overload sensor supply, Pm.27.6, is used to set whether the sensor supply is
switched on again after short-circuit/overload end or remains switched off. If the diagnostics are
activated with the monitoring short-circuit supply, overload supply, sensor supply, Pm.0.0, parameter,
the corresponding error message is generated in the event of an overload.

Electrical outputs
The electrical outputs function is equipped with 2 digital outputs, one of which can be used alterna-
tively for the output of the consumption measurement pulse.
