4.2 START / BUTTONS
Only command devices with a press-button function
(impulse signal) may be connected. Continuous signals
(for example connection of a switch instead of a button)
lead to blocking of all other control commands!
Voltage-free closer contacts (NO) and any number of control
elements with a press-button function, for example a key-ope-
rated push button, can be connected to the „START“ terminals.
Connect up a number of control elements in parallel.
Triggering of a Start command leads to Start or to Stop (while
the door is moving).
4.3 STOP / WICKET DOOR CONTACT
The jumper installed at the works should be removed
when using the connection!
Voltage-free opener contacts (NC) and any number of Emer-
gency-Stop elements or safety equipment can be connected to
the „NOT“ terminals.
Connect up a number of control elements in parallel.
Triggering of a Stop command leads to Stop or prevents start of
the garage door drive.
4.4 CONTACT SAFETY EDGE
Recognition of the contact safety edge must be activa-
ted in the menu b-5 to „1“!
Ohmic contact safety edges (8.2 kΩ) can be connected to the
terminals „L-“ and „LS“.
When using a number of safety edges, up to 3 through switch
strips can be attached with an end safety edge in series.
Use of a safety edge together with photocells, see 4.5 or 4.6.
