CONTROL AND CONNECTION ELEMENTS
Network - UDL 2 connection - (fig. 1)
A 16A EEC plug is connected to terminals Y1a/L1,L2,L3, Y1c/N and
PE.
The network is to be connected to UDL 2 with a three-phase main
switch, as required by the EN 1398 standard.
Connection of the hydraulic motor (fig. 2)
The three-phase hydraulic motor is to be connected to the Y2/U,V,W
and PE terminals.
If the gearmotor is equipped with a neutral conductor, it is to be
connected to terminal Y1c/N*.

Direction of rotation control
Once the hydraulic motor is connected, check the direction of
rotation with the
Ramp UP button.
Caution!
If optional switches (vehicle detector, wheel
chock, protection barrier or door enabling) are
connected to the UDL2 control unit, they must first
be connected in the correct sequence!
If the ramp does not move after you have pressed the Ramp UP
button , reverse the direction of rotation of the hydraulic motor next
to terminal Y2.
Connection of the hydraulic valves (fig. 3-5)
Ramp with hinged lip [P11/P12] (single-valve operation)
The ramp valve is to be connected to the Y4/5,6 (J12) screw terminal.
Ramp with telescopic lip [P21/P23/P25] or hinged lip [P13]
(two-valve operation)
The
Ramp UP
valve connects to the Y4/5,6 (J12) screw terminal and
the
Actuate lip
valve connects to the Y4/3,4 (J13) screw terminal.

Master switch connection
Ramp with telescopic lip [P31/P32/P33] (three-valve operation)
The
Ramp UP
valve connects to the Y4/5,6 (J12) screw terminal, the
Extend lip
valve connects to the Y4/3,4 (J13) screw terminal and the
Retract lip
valve connects to the Y4/1,2 (J14) terminal.
Test program [tSt]
In programming mode it is possible to control the corresponding
valve (1-3) or enable the ON/OFF motor function by pressing the
button on the cover.
Also see BASIC PROGRAMMING below.

Valve connection - triple
Ferrite connection to motor cable (fig. 6-11)
A FERRITE
must
be connected to the motor cable.
Fit three black wires into the ferrite - as shown in the figure, wind
them once around the ferrite - and complete the connection. (There
will now be 6 wires in the ferrite!)
Route the PE cable next to the ferrite, DO NOT run it through the
ferrite itself!
