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.
