0960006660 TOYOTA PUMP ASSY, INJECTI Calibration Data

If the RESET button does not move to the extended position after the engine starts, the engine will NOT be protected by this particular switch.If the RESET button remains in the reset position, the engine oil pump will not develop normal oil pressure. An inspection should be made to correct the problem.
Automatic START/STOP systems use oil pressure to automatically reset.The Engine Protective Devices shutdown controls should be tested every 1000 service hours by authorized personnel.Emergency Stop Push Button
Emergency Stop Push Button (ESPB)The Emergency Stop Push Button (ESPB) requires resetting both the push button and the air inlet shutoff (if equipped) before the engine will start.
Always determine the cause of the engine shutdown. Make necessary repairs before attempting restarting the engine.Emergency shutoff controls are for EMERGENCY use ONLY. DO NOT use Emergency shutoff devices or controls for normal stopping procedure. Refer to the Engine Stopping section of this manual for normal stopping procedures.
Oil Pressure Switch
Typical example of oil pressure switches, mounted in the rear of the junction box.An oil pressure switch has wires connected to the electrical shutoff system for alarm or shutdown functions. The oil pressure switch senses oil pressure at the bearing oil gallery. Switches may close at 48 to 62 kPa (7 to 9 psi) below actual trip point. No resetting procedure is required.Water Temperature Contactor Switch
This contactor switch is a coolant temperature sensor.The water temperature contactor switch is located near the coolant water regulator housing. Excessive water temperature closes the switch. Maximum coolant temperature to trip shutoff is 104°C (219°F). The switch opens as the coolant cools. No resetting procedure is required. The unit has wires connected to the electrical shutoff system for alarm or shutdown functions.
The sensing element must be submerged in the coolant to operate. Be sure to have an adequate water supply in the jacket water system, or engine damage could result.
Coolant Loss Sensor (If Equipped)
The optional coolant loss sensor is usually mounted near the top of the engine expansion tank or radiator. The sensor detects when the coolant level is below a preset minimum level.
This coolant loss switch, shown next to a sight glass, is mounted on the side of a radiator.If the coolant level drops below the minimum level, the sensor may sound an alarm, or cause a shutdown to avoid engine overheating or possible engine damage. Coolant must be added to the radiator or expansion tank to clear or reset the condition. In the event of intermittent engine shutdowns, the coolant water level should be checked. Add premixed coolant water to the fill tank, to within 13 mm (1/2 inch) below the filler tube.Check the expansion tank or radiator daily for proper coolant level.Overspeed Shutoffs
The electrical shutoff for the overspeed switch uses a magnetic pickup mounted in the flywheel housing. The electrical shutoff works through the fuel shutoff solenoid and air inlet shutoff (if equipped).
Magnetic pickup (1), mounted in the flywheel housing (2).Should the engine overspeed, the magnetic pickup will sense the excess speed. If overspeed is sensed, the
