5.3 External control elements
External control elements can actuate various functions:
STOP: The operator can no longer be actuated, a moving door is
brought to a halt.
IMPULSE: The door is opened (exception: if the door has already
reached its opening limit, it then closes). A moving door
cannot be halted.
OPEN: The door is opened. A moving door is brought to a halt.
If the automatic timer is switched on, the OPEN PHASE is
extended.
CLOSE: The door is closed. A moving door is brought to a halt.
If the automatic timer is switched on, the CLOSE PHASE is
reduced.
5.3.1 Connecting external control elements with system plugs
Examples for external control elements with system plugs:
• Push buttons of the Command Series
• Code keypad Command 201
• Key switch Command 311 and 411
Connecting the control elements
Note: If several key switches or code keypads are connected, the coupling for plug
systems (for series connection), item no. 151 228, is required. Instructions on
connecting several control elements are contained in the connection plan
supplied with the coupling.
Before connecting external control elements, the short-circuit plug must be
withdrawn from the X10 (27) socket in the control unit.
The control elements with system plug can now be connected to this socket.
