requirements
1)
Corresponds to the risk time in accordance with EN 60947-5-3. This is the
maximum switch-off delay of the safety outputs after withdrawal of the
actuator.
2)
The error detection time is the time of an internal device error. At least one
of the two semiconductor outputs is switched off safely.
3)
When the operating voltage is switched on, the semiconductor outputs are
switched off and the signal contacts set to LOW potential during the start-
up delay.
4)
The dwell time of an actuator inside and outside the operating range must
be at least 0.5 seconds to ensure a safe detection of internal errors in the
evaluation unit (self-detection).
