6.9 Connecting the EMERGENCY OFF switch
Caution
The EMERGENCY OFF switch must be mounted where it is easily
visible and accessible.
Only use the connection for floating button contacts. External voltage
can damage or destroy the control unit.
When pressed, the EMERGENCY OFF switch stops the operator
immediately and terminates all control unit functions (including dead
man operation).
Place a bridge between terminals 22 and 24 if an EMERGENCY OFF
switch is not connected.
6.10 Connecting the arrester
The arrester is installed in the door and can be connected to the con-
trol unit. Through this connection, the control unit detects when the
arrester kicks in and blocks all control unit functions.
Install a bridge between terminals 20 and 22 if no arrest er is
connected.
