requirements
1)
Using the limit value from EN ISO 13849-1:2008, section 4.5.2
(MTTF = max. 100 years), the BG certifies a PFH
d
2)
Values for a switching current of 50 mA without consideration of the cable length.
3)
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.
4)
The error detection time is the time of an internal device error. At least one of the two
semiconductor outputs is switched off safely.
5)
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.
6)
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).
