.
Parameters relevant to the measured value
cannot be modified.
2damping τ Damping is switched off.
The output signal follows measured value
changes without any delay.
Damping is switched on.
The output signal follows measured value
changes with the delay time τ.
2)
3 SW/Alarm min The alarm current is defined by the setting in
the operating menu.
("Setup" -> "Extended setup" ->
"Curr. output" -> "Output fail mode")
The alarm current is 3.6 mA regardless of the
setting in the operating menu.
4SW/√ The output characteristics is defined by the
setting in the operating menu.
• "Setup" -> "Measuring mode"
• "Setup" -> "Extended Setup" -> "Current
output" -> "Linear/Sqroot"
The measuring mode is "flow" and the output
characterisitcs is "Square root" regardless of
the settings in the operating menu.
5 SW/P2= High The high-pressure side is defined by the setting
in the operating menu.
("Setup" -> "High Press. Side")
The high-pressure side is allocated to the P2
pressure connection regardless of the setting in
the operating menu.
1) If operation is locked by means of the DIP switch, you can only unlock operation again by means of the DIP switch. If ope-
ration is locked by means of the operating menu, you can only unlock operation again using the operating menu.
2) The value for the delay time can be configured via the operating menu ("Setup" -> "Damping").
Factory setting: τ = 2 s or as per order specifications.
