8.2.8 ‘Actual value’ parameter group
Parameter Contents Description
‘Output type’ ‘Analog’/‘Digital’ Digital can only be selected for voltage variants.
‘Output type’ = ‘Analog’ is for current variants.
–
‘Analog’: the current actual pressure is output as
an analogue voltage/current value via the actual
value output.
–
‘Digital’: a digital 24 V signal is output via the
actual value output, which switches as soon as the
actual value is within the parameterised limits.
‘Minimum analog
output’ e.g. 0 V Lower limit of the electrical actual value output in
analogue mode.
The ‘Minimum analog output’
>
"‘Maximum analog
output’ setting is not recommended.
‘Maximum analog
output’ e.g. 5 V Upper limit of the electrical actual value output in
analogue mode.
The ‘Minimum analog output’
>
‘Maximum analog
output’ setting is not recommended.
‘Digital output hys-
teresis’ e.g. 0.200 bar Setting of the limits for the digital output. The set
value corresponds to the maximum deviation from
the setpoint value, which is evaluated as OK for the
digital output.
‘Digital output
delay’ e.g. 100 ms Delayed output of edge changes at the actual
value output in order to filter short status changes
(e.g. with setpoint value jumps). Shorter pulses than
defined in ‘Digital output delay’ are not output.
‘Digital output
logic’ ‘High’/‘Low’ Switchover of the meaning of high or low signal at
the digital output:
–
‘High’: ‘High’ is output if the actual value lies
within the parameterised limits.
–
‘Low’: ‘Low’ is output if the actual value is within
the parameterised limits.
