for configuration of
connections.
8.5 Starting up
A prerequisite for starting up is the proper installation of all measuring lines. All connection must be laid in such a way
that no mechanical forces can act on the device.
Before starting up, the tightness of the pressure connection must be checked.
Any shut-off valves must be opened slowly to avoid pressure surges.
8.5.1 Setting the switch point
An adjustable lock i
s fitted in the front panel of the pressure
gauge. Using the removable adjustment key, the contacts
mounted on the target value indicators can be set to any point on
the range covered by the scale.
For reasons relating to accuracy of switching and the lifetime of
mechanical measurement systems, the switch points should be
positioned between 10% and 90% of the range.
Place the adjustment key on the axle of the adjustable lock.
Press the axle inwards, until the carrier arm grips behind the
adjuster pin on the target value indicator.
By turning the key, adjust the target value indicator to the
desired switch point.
Release the pressure on the axle, and remove the adjustment
key.
8.5.2 Contact function
Function 1: Close contacts with the indication rising in a clockwise direction.
Function 2: Open contacts with the indication rising in a clockwise direction.
Contact assignment:
1st contact left target value indicator,
2nd contact middle target value indicator,
3rd contact right target value indicator
8.6 Subsequent relocation of the gauge
Do not disassemble the device from the measuring point in order to mount it at another measuring
point without cleaning it first (cleaning the Bourdon tube). There is a risk of mixing media with
unpredictable chemical reactions.
9 Servicing
The devices are low maintenance. To ensure reliable operation and a long service life of the device, we nevertheless
recommend that the device is checked regularly. When carrying out maintenance work on the device, the lines must be
depressurized, unintended starting up must be prevented.
In case of frequent ambient temperature changes and heavy use of the red set hand adjustable, it is recommended to
check the adjustment device regularly and replace it if necessary.
