Emergency Stop
In accordance DIN EN 418 the emergency Stop
button has to meet category 0.
Slack-wire Switch
For doors with a cable or chain drive, in
accordance DIN EN 12453 slackness must
be monitored. The control can be done with a
slack-wire switch which can be connected
directly on TS 980 terminals SL+/SL the
reaction is just STOP.

EMERGENCY STOP wiring
This is an additional safety system ( e.g. self-testing light barrier) which shall prevent trapping a
person or obstacle in the door. In accordance with EN 12453 monitoring is required of each
door or shutter where lifting of people or obstacles cannot be prevented (e.g. Grilles).
A separate control system within an end-
of-line resistor of 1K2 should be
connected. TS 980 recognises various
faults - short circuit, contact or supply
interruption.
This safety system is only in effect in the
upwards direction.
When recognising a contact the door
movement upwards Stops and returns
downwards for only 2 sec.. Then the door
Stops until a new command is received.
At the same time the control-display
displays Emergency Stop Entrapment.
Important note
In accordance with EN 954 -1 the safety edge control of the
entrapment device has to meet category 2.
