Safe stop in direction OPEN
Safe STOP OPEN
1. Is actuator in mid-position or at sufficient distance
from the end positions?
2. Operation command via standard controls in direc-
tion OPEN executed?

➥ Check actuator reaction:
Does actuator continue its operation in direction
OPEN?
➥ Check SIL module signal behaviour:
No SIL fault signal?
SIL failure
output (NC contact) = open)
4. Safe STOP OPEN input signal set to 0 V (low)?
➥ Check actuator reaction:
Does actuator stop?
➥ Check SIL module signal behaviour:
No SIL fault signal?
SIL failure
output (NC contact) = open)
Safe STOP OPEN
5.
CLOSE
input signals set to +24 V DC (high)?
☒ ✓ = Executed
☒ Yes = Condition met
☒ No = Condition not met
If the answer to one of the questions is no, the safety instrumented system must be checked.
