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 .
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 rotary side panel [P11/P12]
The ramp valve is to be connected to the Y4/5,6 (J12) screw
terminal.
Ramp with telescopic side panel [P21/P23/P24] (operation
with 2 valves)
The valve Lift ramp is to be connected to the Y4/5,6 (J12) screw
