On the tSt program

This program is used if you are not familiar with a ramp and you want
to operate it with a UDL2 controller.

For instance, suppose you wish to use a telescopic ramp: connect
it to the controller (valves and motor) and select the tSt program.
You can now check that the motor is operating properly by pressing

AUTORETURN. To check that the valves are properly hooked up,

use the Ramp UP, Extend lip and Retract lip buttons. For example,
if pressing Extend Ramp causes the ramp to raise, you must swap
the pair of wires connected to valve 1 (connector Y4 1-2) with those
connected to valve 2 (connector Y4 3-4), and so on. This allows the

UDL2's programs to operate correctly with the new ramp.

The control unit is totally assembled and wired, ready for connection.
The control unit is to be kept inside its packaging during transport

and storage, if any, in order to prevent any damage.

For disposal, it is necessary to separate

− metals
− plastic elements
− electrical components
− lubricants.
