Connection example
The following connection example shows a possible circuit structure with redundant design at the cable level as
well.
The signals of the emergency stop chain are evaluated by a safety relay (ESM from EUCHNER).
The overall control concept into which the pull rope switch RPS is integrated must be evaluated by the end
consumer/machine designer in accordance with EN ISO 13849-2.

Setup
Mechanical function test
It must be possible to actuate the pull rope easily at every point of the cabling rope pull system. As a check,
actuate the pull rope several times.
Electrical function test
Activate the rope pull system by means of the RESET actuating cylinder.
Start the installation/machine.
Actuate the pull rope / EMERGENCY STOP button: this results in the safety contacts opening immediately.
The safety contacts close only after renewed operation of the RESET actuating cylinder.
