8.4Power supply

If power supply wiring is installed incorrectly, or the flowmeter is improperly grounded, the meter will not operate properly. Follow these steps to check power supply wiring and grounding:

1.If a switch was installed in the power supply line, be sure the switch is in the ON position.

2.Check the power supply voltage, and make sure it matches the voltage listed on the label in the flowmeter’s power supply wiring compartment. See Figure 8-2.

3.Turn power supply OFF.

8.4Power supplyManual backgroundManual background WARNING

Line voltage can cause electric shock or flowmeter damage.

Disconnect power before accessing power supply terminals.

4.At the terminals indicated in Figure 8-2, make sure wires are secured tightly and making good connections. Make sure no bare wires remain exposed.

5.Wiring must be 20 AWG (0,5 mm²) to 16 AWG (1,5 mm²) wire.

6.Maximum wire lengths for a DC power supply are as follows:
