Omega LVC-100 Maintenance, Wiring as a P-Channel or N-Channel output, General, Cleaning Procedure

WIRING

Step Nine

Wiring as a P-Channel or N-Channel output:

The powered level switch can be substituted for either a P-Channel (PNP, sourcing) output or a N-Channel (NPN, sinking) output.

Normally Open DC Load as a P-Channel Output:

To wire as a NO P-Channel output, follow the directions below. The Red wire connects to Positive (+) of the power supply and the Black wire connects to Negative (-). The Green wire is jumpered to the Red wire while the White wire is connected to the LOAD. Jumper the LOAD back to the Negative (-) to complete the circuit.

MAINTENANCE

Step Ten

General:

The powered level switch requires no periodic maintenance except cleaning as required. It is the responsibility of the user to determine the appropriate maintenance schedule, based on the specific charac- teristics of the application liquids.

Cleaning Procedure:

1.	Power: Make Sure that all power to the sensor, controller and/or
	power supply is completely disconnected.
2.	Sensor Removal: In all through-wall installations, make sure

	that the tank is drained well below the sensor prior to removal.
	Carefully, remove the sensor from the installation.
3.	Cleaning the Sensor: Use a soft bristle brush and mild deter-
	gent, carefully wash the powered level switch. Do not use harsh
	abrasives such as steel wool or sandpaper, which might damage
	the surface sensor. Do not use incompatible solvents which may
	damage the sensor's PP, PFA, PVDF or Ryton plastic body.
4.	Sensor Installation: Follow the appropriate steps of installa-

Normally Closed DC Load as a P-Channel Output:

To wire as a NC P-Channel output, follow the directions below. The Black wire connects to Positive (+) of the power supply and the Red wire connects to Negative (-). The Green wire is jumpered to the Black wire while the White wire is connected to the LOAD. Jumper the LOAD back to the Negative (-) to complete the circuit.

tion as outlined in the installation section of this manual.

Testing the installation:

1.Power: Turn on power to the controller and/or power supply.

2.Immersing the switch: Immerse the sensing tip in its applica- tion liquid, by filling the tank up to the switches point of actua- tion. An alternate method of immersing the switch during prelim- inary testing is to hold a cup filled with application liquid up to the switch's tip.

3.Test: With the switch being fluctuated between wet and dry states, the switch indicator light in the controller should turn on and off. If the controller doesn't have an input indicator, use a volt- meter or ammeter to ensure that the switch produces the correct signal.

4.Point of actuation: Observe the point at which the rising or falling fluid level causes the switch to change state, and adjust the installation of the switch if necessary.
