Table 8-2 Conditions indicated by optional LCD

Optional LCD reads:	Condition
Mass or volume flow rate (such as “100.00”)	Normal operation
“OL0”	Flow rate has exceeded upper limit of display
“ 88.8.8.0”	Startup and initialization
“ZERO0”	Zero in progress
“SLUG0”	Slug flow (density below or above user-defined limits)
“ELEC0”	Transmitter hardware failure, zero failure
“SENS0”	Sensor failure, faulty cable, process over range, density above or
	below transmitter limits
Remains OFF	Power supply failure

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.

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:

Power-supply wire size		Maximum length
16	AWG (1,5 mm²)	1500 feet (450 meters)
18	AWG (0,75 mm²)	1000 feet (300 meters)
20	AWG (0,5 mm²)	600 feet (200 meters)
