Setting a delay for the switching outputs
Follow these steps to modify the time before an output switches after a fault. The
maximum delay time is 50 seconds.
Procedure
1. Select the switch-on delay parameter for the output from the extended functions
menu.
• Select
dS1
to modify the switch-on delay for OUT1.
• Select dS2 to modify the switch-on delay for OUT2.
2. Press and hold Set to modify the parameter value.
3. Set the value between 0.1 and 50 seconds.
4. Select the switch-off delay parameter for the output from the extended functions
menu.
• Select
dr1
to modify the switch-off delay for OUT1.
• Select dr2 to modify the switch-off delay for OUT2.
5. Press and hold Set to modify the parameter value.
6. Set the value between 0.1 and 50 seconds.
Setting the value to 0.0 deactivates the delay.
Setting the output logic for the switching outputs
Follow these steps to change the output logic for the switching outputs.
Procedure
1. Select P-n from the extended functions menu.
2. Press and hold Set to modify the parameter value.
3. Set the parameter to
PnP
or
nPn
.
4. Press Mode/Enter .
Setting damping for the switching signal
Damping the switching signal prevents the outputs from erroneously switching because of
erratic pressure readings. The damping value is the response time in seconds between
pressure change and change to the switching status. The damping value also influences
the value displayed on the pressure transmitter and the switching frequency (fmax = 1 ÷
2dAP).
Procedure
1. Select dAP from the extended functions menu.
2. Press and hold
Set
to modify the parameter value.
3. Set the value between 0.0 and 30 seconds.
A value of 0.0 seconds deactivates damping.
4. Press Mode/Enter .
