Function of the operating elements
5.2.2
Locking/unlocking operation
Once you have entered all the parameters, you can lock your entries against unauthorized and
undesired access.
!
Note!
If operation is locked by means of the DIP switch, you can only unlock operation again by means of
the DIP switch. If operation is locked by means of the operating menu, you can only unlock
operation again using the operating menu.
Locking/unlocking via DIP switches
DIP switch 1 on the electronic insert is used to lock/unlock operation.

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)
The value for the delay time can be configured via the operating menu ("Setup" -> "Damping").
Factory setting:
= 2 s or as per order specifications.
Operating key(s)
Meaning
"Zero"
pressed for at least
3 seconds
Get LRV
•
"Pressure" measuring mode
The pressure present is accepted as the lower range value (LRV).
•
"Level" measuring mode, "In pressure" level selection, "Wet" calibration mode
The pressure present is assigned to the lower level value ("Empty calibration").
!
Note!
No function is assigned to the key if level selection = "In height" and/or calibration mode
= "Dry"
•
"Flow" measuring mode
There is no function allocated to the "Zero" key.
"Span"
pressed for at least
3 seconds
Get URV
•
"Pressure" measuring mode
The pressure present is accepted as the upper range value (LRV).
•
"Level" measuring mode, "In pressure" level selection, "Wet" calibration mode
The pressure present is assigned to the upper level value ("Full calibration").
!
Note!
No function is assigned to the key if level selection = "In height" and/or calibration mode
= "Dry"
•
"Flow" measuring mode
The pressure present is accepted as the maximum pressure ("Max. pressure flow") and
allocated to the maximum flow ("max. flow").
"Zero"
and
"Span"
pressed simultaneously
for at least 3 seconds
Position adjustment
The sensor characteristic curve is shifted such that the pressure present becomes the zero value.
"Zero"
and
"Span"
pressed simultaneously
for at least 12 seconds
Reset
All parameters are reset to the order configuration.
