Sending Unit for Water Temperature
Sending Unit For Water Temperature
(1) Connection. (2) Bushing. (3) Bulb.The sending unit for water temperature is an electrical resistance. It changes the value of its resistance according to the temperature which the bulb (3) feels.The sending unit is in a series circuit with the electrical indicator. When the temperature is high, the resistance is high. This makes the indicator have a high reading.The sending unit must be in contact with the coolant. If the coolant level is too low because of a sudden loss of coolant while the engine is running or because the level is too low before starting the engine, the sending unit will not work correctly.Sending Unit for Oil Pressure
Sending Unit For Oil Pressure
(1) Connection. (2) Bushing.The sending unit for oil pressure is an electrical resistance. It has a material which changes electrical resistance according to pressure which it feels.The sending unit for oil pressure is in a series circuit with the electrical indicator. As the pressure on the sending unit changes, the reading on the indicator changes in the same way.Electric Hour Meter
Hour Meter Wiring Diagram
(1) Electrical hour meter. (2) Pressure switch. (3) To alternator or battery.Electric hour meter (1) measures the clock hours that the engine operates. The hour meter activates when pressure switch (2) closes. Pressure switch (2) closes the circuit from the positive terminal on the alternator or battery when the engine oil pressure is above approximately 6 psi (40 kPa).Electric Tachometer Wiring
(1) Magnetic pickup. (2) Terminal connections - terminals 7 and 8 on standby governor control. (3) Tachometer. (4) Ground connection - governor control chassis ground. (5) Governor control terminal strip. (6) Wiring connections - for second tachometer circuit. (7) All wire must be 22AWG shielded cable or larger. (8) Dual speed switch terminal strip. (9) Ground connection - ground to engine.Wiring Diagram

(12) Automatic control switch (ACS).An automatic start/stop system is used when a standby electric set has to give power to a system if the normal (commercial) power supply has a failure. There are three main sections in the system. They are: the automatic transfer switch, the start/stop control panel (part of switch gear) and the electric set.Automatic Transfer Switch
Automatic Transfer Switch (Typical Illustration)The automatic transfer switch normally connects the 3-phase normal (commercial) power supply to the load. When the commercial power supply has a failure the switch will transfer the load to the standby electric set. The transfer switch will not transfer the load from commercial to emergency power until the emergency power gets to the rated voltage and frequency. The reason for this is, the solenoid that causes the transfer of power operates on the voltage from the standby electric set. When the normal power returns to the rated voltage and frequency and the time delay (if so equipped) is over, the transfer switch will return the load to the normal power supply.Control Panel (Later)
Electronic Modular Control Panel (EMCP II)
(1) Optional panel lights. (2) Optional governor switch (shown) or speed potentionmeter. (3) Optional starting aid switch. (4) Engine control switch. (5) Optional alarm module (shown) or synchronizing lights module. (6) Voltage adjust rheostat. (7) Emergency stop push button. (8) Generator set control. (9) Optional panel light switch.The main function of the control panel is to control the start and shutoff of the engine.The engine control on the automatic start/stop control panel is an automatic engine control switch (ECS) with four positions. The positions of the engine control switch (4) are: OFF/RESET, AUTO, MAN./START, and COOLDOWN/STOP. Each light goes ON only when an abnormal condition in the engine stops the engine. The light for the condition in the engine that stopped the engine is ON even after the engine has stopped. Engine control switch (4) must be moved to the OFF/RESET position for the light to go OFF. Each light will go ON, for a light test, when the light is pushed in and held.When the generator is to be used as a standby electric power unit, the automatic control switch is put in the AUTO position. Now, if the normal (commercial) electric power stops, the engine starts and the generator takes the electric load automatically. When the normal (commercial) electric power is ON again, or the electric load, the transfer switch opens its contacts to the generator, and closes its contacts to the normal (commercial) electric power. After the transfer switch for the generator opens, the engine automatically stops, usually after running for a cooldown time.When the automatic engine control switch (ECS) is moved to the MAN./START position, the engine starts. It may now be necessary for the circuit breaker for the generator electric power to be closed manually to the load. If the generator is a standby electric power unit and the automatic engine control switch (ECS) is in the MAN./START position when normal (commercial) electric power stops, the automatic engine control switch (ECS) can be put into the AUTO position and
