Mechatronic Solenoid Valves (MV), Electronic Pressure Control Valves (EDS)

Mechatronic Solenoid Valves (MV), Electronic Pressure Control Valves (EDS)

The mechatronic (electronics module and hydraulic unit) has various solenoid valves and electronic pressure control valves.


Brief component description (solenoid valves)
The solenoid valves are 3/2-way valves, i.e. valves with 3 connections and 2 switch positions.

Brief component description (electronic pressure actuators)
The electronic pressure actuators convert electric current into a proportional hydraulic pressure and thus activate hydraulic valves with their corresponding shift elements.

Three types of EDS are fitted:
- EDS with rising characteristic curve (orange cap)
Pressure range 0 to 4.7 bar
Supply voltage 12 volts
Resistance 5.05 Ohm (at 20 °C)
- EDS with rising characteristic curve (yellow cap)
Pressure range 0 to 4.6 bar
Supply voltage 12 volts
Resistance 5.05 Ohm (at 20 °C)
- EDS with falling characteristic curve (blue cap)
Pressure range 4.6 to 0 bar
Supply voltage 12 volts
Resistance 5.05 Ohm (at 20 °C)

Mechatronic calibration following repairs
If the mechatronics has to be renewed in the course of repairs, it must be labelled as a replacement mechatronics using the service function "Mechatronic calibration".
After replacement of the entire gearbox, the service function does not have to be run, as the gearbox is already fully calibrated on delivery.
In all cases, it is advisable to delete stored adaptation values.
