Description of product
4.1 Safety concept
4.1.1
Safety equipment independent of the processor
All safety-related parts are incorporated in the safety chain (sensors and actuators)
directly and independently of the microprocessor.
The integrated microprocessor registers and reports from the results of the safety
monitoring process, but is not able to influence the safety measures triggered with
the exception of reversing the closing edge.
The possibility of uncontrolled gate movement triggered by the microprocessor is
therefore ruled out and is prohibited by the hardware.
4.1.2
Monitored safety equipment
The evaluation of all safety equipment corresponds to the standard set by the me-
chanical engineering industry:
1. Before every gate movement, the gate’s function is checked automatically.
2. If this function check produces an error, the system is shifted into error status
(red light(s) flash(es), if fitted).
3. The gate system cannot be started if an error is present. Normal operations
can only be continued once the cause of the error has been rectified.
