INSTALLATION INSTRUCTIONS FOR MODEL 512 OIL LEVEL CONTROLLERS WITH ADAPTERS

Note: For fire safe oil level controllers (512-FS) see additional instructions in this work sheet covering installation of fire safe valves.

Figure 1- Side View of 512 I. SWITCH SPECIFICATIONS

Switch Specifications: Case to Ground: 2 AMP, 30 VAC/VDC

Switch Adjustment:
Improper setting may result in damage to engine. Switch is
factory set at ½” drop. If adjustment for the application is
necessary, refer to figure 1 and follow these instructions:

• Remove the cover of the condulet housing (A) by

unscrewing the 6 screws(B).

• Rotate the slotted set screw(C) counter-clockwise to lower

the switch trip point 3/16”.

• Rotate the slotted set screw(C) clockwise to raise the

switch trip point to a maximum of ½”.

• Attach the wire from the controller to the low tension

terminal on the magneto.

NOTE: The switch is not factory adjusted for proper
shutdown level.

Switch adjustment is not recommended.

II. INSTALLATION AND MAINTENANCE INSTRUCTIONS FOR OIL INLET VALVE:

• Connect the oil supply line to the oil inlet on the oil level controller. The minimum recommended supply line is ¾” I.D. The supply

line must be clean and it is recommended that it be flushed with solvent before installation.

• It is recommended that the oil supply line is connected using hose barb or tube fittings, using a reliable thread sealant. Do not use

Teflon tape.

• Connect the oil supply line to the oil supply tank. If there is no existing valve at the tank or the existing supply outlet, a shut-off valve

should be placed in the line to prevent oil loss when cleaning the inlet screen or filter.

• The oil inlet valve is adjusted to maintain the oil level at the center of the sight glass. Low or high levels are often caused by two

problems:

1. Excessive oil inlet pressure, which will cause the unit to overfill.

2. Improper equalizing lines between the crankcase and the controller will also result in improper levels.

Note: 512 models require a minimum of 2’ of head pressure and a maximum of 12’ of oil inlet head pressure.

& 275) AND FS OPTIONS

• Remove the visual oil gauge assembly from the engine and replace it with the oil level controller and adapter assembly supplied with

a gasket and mounting bolts when applicable.

OIL LEVEL CONTROLLERS WITH

• Remove the visual oil gauge assembly from the engine and replace it with the oil level controller and adapter assembly supplied with

a gasket and mounting bolts.

• If the visual oil gauge was vented back to the engine crankcase, remove the vent from the top of the adapter and tie it back to the

crankcase with tubing.

Note: It is important to ensure that there are no loops in this line for it must be trap free and self draining.

•

OPTIONS

• Set the controller so that the centerline of the sight window corresponds to the desired oil level in the crankcase.

• Mount the controller close to the crankcase and connect the hose from the ¾” outlet located on the controller to the crankcase.

NOTE: The outlet port on the oil level controller must be located below the oil level in the crankcase.

• An equalizing line must be used between the controller and crankcase in order to equalize the pressure. The tubing must be a

minimum of 1/2” I.D. and must be kept under 2 feet. DO NOT loop this line. It must be trap free and self draining, with a downward
pitch flow by gravity.

–11 AND –11-FS OPTION (for Mechanical Lubricators): See Figure 3

Drill holes in the lubricator housing as shown, and mount

the controller with the inlet located on the top side using the
seal washers and mounting bolts provided.

• Place the seal washers between the controller and the

lubricator housing.

OIL LEVEL CONTROLLER WITH

• Remove the triangular blind flange located on the compressor and mount the controller assembly in its place.

NOTE: It is important to install a drain line between the drain outlet of the compressor and the controller.
