Becker a100/25, Руководство по сборке и эксплуатации, Страница: 12 / 16

To connect the drive to the control unit, only use original manufacturer-approved 12-core or 18-core cables. The connecting cable
is plug-in. In order to ensure strain relief and the degree of protection, the gland must not be undone. The 10-pole jumper plug in
the drive must be removed before plugging in the 18-core cable. The plugs feature reverse polarity protection and click audibly
into place. The yellow/green protective conductor wire must be connected to the designated push-on connector . Make sure
that it engages firmly.

of the housing as shown in the diagram.

Install the protective conductor (green/yellow) below the black connecting
cables.

cable tie.
Checking the running direction
The direction of drive rotation depends on the mains connection to the control unit and must be checked first. Proceed as follows:
• Move the door into the semi-opened position using the emergency manual operation function.
• Insert the mains plug of the control unit into the socket or switch the main switch of the control unit on.
• Check that the control unit is in dead-man mode.
• Use the OPEN and CLOSE buttons to verify whether the running direction of the door corresponds to the buttons pressed.
If the running direction of the door does not correspond with the button commands, change the direction of rotation as described
in the Assembly and Operating Instructions for the control unit. Then check the running direction again.
Setting the door limit positions
The drive comes with 6 cam-operated end switches as standard. All cams have 12 lock-in positions for quick adjustment. Check
that the control unit is in dead-man mode.
Proceed as follows to set the limit switch:
1. Turn all 6 cams out of the movement range of the door.
2. Use the DOWN button of the control unit to move the door to just before the lower limit position.
