Connection


Control unit

The control unit must be installed separately from the engine. Control unit working temperature must be between - 40 °C to +85 °C.


Accelerator pedal (VE engines)

Idling: 0-5 V (standard value 0.3 V)

Full throttle: 0-5 V (default value 4.6 V)

A fault code is generated when the voltage is:

U > 4.9 V (standard value)

U < 0.1 V (standard value)


Engine speed potentiometer/external voltage input (GE engines)

Rotary potentiometer for fine adjustment of Volvo engine speed (GE engines)

On 1500 rpm or 1800 rpm GE engines, the Volvo engine speed can be finely adjusted ±5 %. A fault code is generated when the voltage is:

U > 4.8 V (standard value)

U < 0.2 V (standard value)

This accelerator pedal/potentiometer corresponds to the control unit standard value (0.5 V or 4.5 V respectively).

The end position resistor is used to detect electrical faults in the accelerator/potentiometer (end position resistors are built into many accelerators/potentiometers and do not need to be added in these cases).


1500/1800 rpm switch

This function makes it possible to switch engine speed between 1500 and 1800 rpm. Switch type, two-position (NO).

Droop switch

The switch must be closed to obtain droop. Switch type, two-position (NO).


Alarm, low oil pressure

Max. power 3 W

Voltage 12 V/24 V

Alarm, high coolant temperature

Max. power 3 W

Voltage 12 V/24 V


Tachometer

Tachometer used, graduated 0-2600 rpm and with adjustable input frequency.

44 pulses/r (420/620 engines)

48 pulses/r (520/720 engines)


Diagnostic lamp

Max. power 3 W

Voltage 24 V


Diagnostic button

Switch type, closing (NO), spring biased.

To read the fault codes, please refer to the Fault findingchapter.


VODIA input

Deutsch 6-pin connector

To read the fault codes, please refer to the Fault findingchapter.


Parameter setting


Adjustable parameters

The VODIA tool (including Penta EDC 4 software) can be used to read and adjust the parameters below, in Parameter Programmingmode. For instructions, see VODIA User´s Guide.

NOTE! Special authorization is needed to be able to adjust certain parameters.


Coolant temperature protection (Special authorization needed)

Chooses whether engine protection should be activated in relation to high coolant temperature.

Alternative positions Offor On

Default value: On

If On, the coolant temperature warning lamp lights up at 110 °C (goes out at 109°C)

The engine is shut off at 113 °C after 30 sec.

Coolant level protection (Special authorization needed)

Chooses whether engine protection should be activated in relation to low coolant level.

Alternative positions Offor On

Default value: On

If On, the control unit does not check this function until 25 s after starting. When the control unit receives a low coolant level signal, the engine is shut off after 5 sec.


Oil pressure protection (Special authorization needed) Chooses whether Volvo engine protection should be activated in relation to low oil pressure.

Alternative positions Offor On

Default value: On

If On, the control unit does not check this function until 30 s after starting.


The limit values depend on engine speed. The oil pressure warning lamp lights up when the limit value is reached, and goes out again when the oil pressure has risen 10 % above the limit value. The engine is shut off when oil pressure falls to 80 % of the limit value. Examples of default values: 800 rpm the oil pressure warning lamp lights up at 0.9 bar (goes out at 1 bar) and the engine is shut off at 0.72 bar.


2000 rpm the oil pressure warning lamp lights up at 2.5 bar (goes out at 2.75 bar) and the engine is shut off at 2 bar.



Read-only parameters

The VODIA tool (including Penta EDC 4 software) can be used to read the values below in Log testmode.

For instructions, see VODIA User´s Guide.

Battery voltage

Coolant temperature

Charge air pressure

Oil pressure

Fuel temperature

Engine speed

Throttle control %

Droop %

Throttle control voltage (Only in Parameter, programming

position on VODIA tool)

Engine total running time

Engine load %


Fine adjustment, engine speed regulator

Use the VODIA tool (including Penta EDC 4 software), to read and adjust the P, I and D sections of the engine speed regulator. In some cases, this can offer more stable and more even engine running.


PID = Proportional, Integrating, Differential

The P section amplifies (Gain). A reduced value (Fig. 1) gives slower regulator reaction with change of load. An increased value (Fig. 2) gives a faster reaction. The I section stabilizes (Stability). A reduced value (Fig. 3) increases the time for system recovery with change of load. An increased value (Fig 4) gives a shorter recovery time.



The D section stabilizes (Differential). Reacts to the magnitude of the engine speed change. A reduced value (Fig 4) gives reduced sensitivity. An increased value (Fig. 5) gives increased sensitivity. Before any adjustments are made, the current values of the P, I and D sections of the PID regulator should be noted.

NOTE! Without the default values, the engine speed regulator/actuator can not be restored if adjustment is not successful.

For instructions, see VODIA User´s Guide.

How to Properly Install Diesel Engine

Installing diesel engine is an important part for engine operation. No matter what will you use the engine for, the first thing is to install it on the machine you want to use. Installation of diesel engine is not an easy thing that everyone can do. How to install engine properly is a point for many users to learn. Moreover, properly installing engine is crucial because any mistaken installation step could lead to engine damage and personal hurt. One of the largest challenges of the engine re - manufacturing business is often associated with improper engine installation. We all know that everyone reads all of the literature that comes with each remain  engine – right? Even after reading all of the paperwork technicians still seem to find creative ways to damage the engines performance and longevity. Enough humor – this article will discuss basic diesel engine installation  and how you can prevent premature engine failures. Imagine the most beautiful remanufacture...
