1 Socket for LCI adapter
2 Analog output 0/4 ... 20 mA (electrically isolated)
3 Power supply 24 V AC/DC
1. A shielded, four-core cable (e.g., 4 x 1 mm
2. Release the four screws on the connection head cover of the flowmeter sensor and remove
the cover.
3. Connect the four cores to the terminals of the flowmeter sensor electronics.
NOTICE - Potential damage to parts!
Electrical isolation is only ensured if terminal 4 is not connected to terminal 2 of the supply
power.
4. Attach the shielding to the EMC cable entry.
IMPORTANT (NOTE)
If the shielding is routed directly into the housing, it will not have the desired effect (shielding
effect will be lost).
