2.3.11 Configuration changes

The setting of the switch points is made in the factory in accordance with the
ordering information. Following any change by the operator, the switch points must
be checked. The marking must, for example, be updated via a suitable adhesive
label. The instrument should be secured against the switch points being changed
through the provided lead sealing of the setting elements.
2.3.12 Commissioning
All applications
The operability of the switching function of the DPGS40TA.100-xxS differential
pressure gauge must be tested both during commissioning and at appropriate
intervals. Both the nature of the testing as well as the chosen intervals are the
responsibility of the user.
Additional for applications with low demand rate
The interval for the proof test usually conforms to the PFD
the standard. Normally the proof test takes place every year, see certificates
V 495.01/15 and V 405.02/15.
2.3.13 Proof test of the safety function
Through a test of the entire safety function, check whether the switch is operating
correctly.
