Optional features on the Series 40E engine include the following:
Section 7.2.1
Cruise Control
Cruise Control provides vehicle speed using automotive style On, Off, Set/Coast, and Resume/Accel switches. Speed control is disabled when the service brakes are applied, the clutch pedal is depressed, or an automatic transmission is placed in neutral. The accelerator pedal can be used to provide a speed increase from the cruise speed selected. See Figure
“Cruise Control Switches”
.

Section 7.2.2
Throttle Control
The Series 40E engines are compatible with both stationary and mobile PTO applications. Remote and in-cab throttle control locations are available. Also, the throttle control feature can be used as an electronic hand throttle to be used during warm-up procedures or cold weather idle operation. See Figure
“Engine Speed Control “
.

Section 7.2.3
Road Speed Limiting/Governor
The Road Speed Limiting/Governor limits vehicle speed to an owner/operator programmable maximum speed.
Section 7.2.4
Body Equipment Manufacturer Provisions
Additional circuits and connector junction blocks are provided in the engine compartment on the left side of the cowl. These circuits include provisions for:
- Remote engine speed control
- Remote PTO (engine speed) control commands
- Additional power and control circuits for aftermarket added equipment
The standard electrical system will provide breakout connector access to the speed control circuits.
Section 7.2.5
Engine Warning System
The Engine Warning System illuminates the red Stop Engine lamp, and actuates a buzzer when warning thresholds for coolant temperature, engine coolant level and/or engine oil pressure (low) are exceeded. See Figure
“Engine Warning System “
.

Section 7.2.6
Engine Shutdown System
The Engine Shutdown System shuts down the engine after 30 seconds of operation beyond the critical threshold values for coolant temperature and/or oil pressure. The above mentioned warning system is included with this shutdown system. The engine may be restarted after shutdown if it is mechanically capable of starting. See Figure
“Engine Protection System”
.

Section 7.2.7
Idle Shutdown
The Idle Shutdown feature provides automatic engine shutdown after a 2 to 120 minute idle time has been exceeded.
The allowed idle time can be customized to the maximum or minimum intake air temperatures at which extended idle would be allowed, or to whatever the owner desires.
In the event that the idle shutdown feature is triggered, the ECM will flash the Oil/Water light on the dash and sound the buzzer 30 seconds before the engine shuts down, indicating the condition. A fault code will also be set after the shutdown is completed.
When this feature is selected, the Cold Ambient Protection feature is automatically disabled.
Section 7.2.8
Hydraulic Pressure Governor
The optional Hydraulic Pressure Governor can be used on special trucks (firetrucks) equipped with hydraulic pumps where output pressure is controlled by adjusting the engine r/min.
Body builder connections are provided and the ECM can be programmed for this purpose on request.
This feature can be programmed to fit the operator needs. Engine r/min ramp rate and hydraulic pressure governor gain adjustments are among the available variables that allow this feature to be such a versatile tool.
Section 7.2.9
Engine Fan
The engine fan allows the ECM to control the engagement and disengagement of the engine fan, depending on the Engine Coolant Temperature (ECT) or air conditioner demand.
The ECM can also be programmed to utilize the engine fan as an engine retarder device.
Section 7.2.10
Radiator Shutters
Electronically controlled radiator shutters can also be controlled by the ECM to maintain a proper engine coolant temperature during cold weather operation. This improves the performance of the engine and benefits the operation of cab accessories such as the heater and the windshield defroster.
Fuel mileage can also be benefited from this feature.
