Mounting and start-up
5.14.1 Connecting the electrical
power
Risk of malfunction due to incorrect sequence
of mounting, installation and start-up.
Keep the following sequence.
1. Remove the protective caps from the
pneumatic connections.
2. Mount the positioner on the valve.
3. Connect the supply air.
4. Connect the electrical power.
5. Perform settings.
Î Connect the electrical power (mA signal)
asshowninFig.26.
5.14.2 Switching amplier
according to EN 60947-
5-6
For operation of the limit contacts, switching
ampliersmustbeconnectedintheoutput
circuit. They must comply with the limit val-
ues of the output circuits conforming to
EN60947-5-6.
Î Observe the relevant regulations for in-
stallation in hazardous areas.
For applications in safe areas (non-hazard-
ous areas), limit contacts can be directly in-
terconnected to the binary input of the PLC in
accordancewithIEC61131.Thisappliesto
the standard operating range for digital in-
putsaccordingtoClause5.2.1.2of
IEC61131-2withtheratedvoltageof
24VDC.
