2.4.1 Single Function "SF" (EF) / Dual Function "DF" (DF)
Single Function EF
Single function or SF stands for the operating mode in which, when the Pull command is given, the brake is
automatically released simultaneously by a special mechanism in the winch.
Dual Function DF
Dual function or DF stands for the operating mode in which, when the Pull command is given by the receiver, the
Release command is send at the same time to the winch, because the winch doesn’t have an automatic release.
2.4 Parameterisation
Never fix the jumper in a position other than those shown!
Winches differ from manufacturer to manufacturer and the type must be established by a
qualified
person
based on the following procedure:
Connect the contact for the Pull solenoid valve briefly to the positive voltage supply.
If the winch pulls in, the operating mode EF on the receiver is correct.
If you only hear a loud clicking noise and the winch does not move, the brake is not automatically
released with the command Pull. In this case the operating mode DF on the receiver is correct which
also releases the brake.
When setting up the receiver for the first time, make sure that the proper operating mode is selected. If
the solenoids of the winch have no additional circuit elements or there is only one diode between the
connections for clutch and brake, then the DF field must be marked on the receiver type plate.
With pneumatic winches, because of the response delay, additional electronics are often provided,
which are inserted in the feed line for the valve brake and the clutch. In this case, the EF field must be
marked on the receiver type plate. If you are in any doubt, please contact us and we will be glad to help
solve any problems.
Changing the operating mode in the receiver (Only to be carried out by qualified person!):
Remove the circuit board from the receiver housing. (See figure in Sec. 2.5)
Change the position of jumper J1 on the board if required
