Connection and Parameter Setting of Volvo Industrial Engine


Connection of Volvo Industrial Engine

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 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 finding” chapter.
VODIA input
Deutsch 6-pin connector
To read the fault codes, please refer to the “Fault finding” chapter.

Parameter setting of Volvo Penta Engine

Adjustable parameters
The VODIA tool (including Penta EDC 4 software) can be used to read and adjust the parameters below, in “Parameter Programming” mode. 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 “Off” or “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 “Off” or “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 engine protection should be activated in relation to low oil pressure.
Alternative positions “Off” or “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 test” mode.
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”.

Adjustment
1. Use the VODIA tool and note the current values of the P, I and D sections of the PID regulator.
2. Start the engine.
3. Run the engine at working speed without load, and first increase the value of the P section of the PID regulator until unstable (oscillating) engine speed is achieved. Then reduce the parameter by 1-2 % until the engine speed is stable again.
4. Then adjust the I section of the PID regulator in the same way as above.
5. If the engine still runs badly and no other adjustments help, increase the D section of the PID regulator until the engine only has a very small increase in speed when load is applied or removed, please refer to fig. 6.
NOTE! The few times that the D section may need to be adjusted include cases where the application has a flexible coupling or extremely low flywheel inertia.
6. Adjust the P and I sections again as above, if necessary.
7. Check the industrial generator engine response.

What Is the Difference Between Electric Motor and Electric Generator

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction. An electric generator operates in the reverse direction, converting mechanical energy into electrical energy. Electric generator can be divided into various type, open type, silent type, trailer type, portable type and container type, etc. Electric generator is mainly composed of diesel engine & alternator. Electric generator set is mainly composed of engine, alternator, control module, and common base. Electric generator :- Electric generator is a type of machine which converts mechanical input (energy) into electrical output (...

Engine Fault Code Messages - Volvo Penta Engine

Volvo Penta Engine Fault Code When a malfunction has occurred and the diagnostic system has generated one or more fault codes, these are read out differently depending on the equipment used. Please refer to “Fault code messages”. If the system indicates that a fault code has been set: 1 Cut engine speed to idle, or shut the Volvo engine off. 2 For DCU/DU Read the fault code from the display, please refer to Reading fault codes via the DCU or Reading fault codes via the DU. For CIU press the diagnostic button and read the fault code, by observing the flashing of the diagnostic lamp. Refer to Reading fault codes via the diagnostic lamp, CIU. 3 Look up the fault code in the Fault Code Register chapter and take the recommended measures. Reading fault codes via the DU (Display Unit) Depending on the severity of the fault the text, either WARNING! or ALARM STOP (a buzzer sounds) will be shown on the display 1 Press any button to come to the fault list. The f...
