Safe Esd Reaction To "Forced Torque Seating In End Position; Safe Esd Reaction To "No Seating - AUMA SQ 05.2-SQ 14.2 Manual

Checklists
Table 27: Proof test checklist
Configuration
Safe CLOSING (Safe ESD in direction CLOSE)
1. Is actuator in mid-position or at sufficient distance
from the end positions?
Safe ESDa Safe ESDb
2. and
set to 0 V (low)?
➥ Check actuator reaction:
Safety operation initiated?
3. Wait until actuator limit switch trips.
➥ Check actuator reaction:
Safety operation stopped when reaching limit switch
CLOSED?
4. Safe ESDa and Safe ESDb
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.
11.2.7. Safe ESD reaction to "Forced torque seating in end position" (torque after limit evaluation)
Table 28: Proof test checklist
Configuration
Safe CLOSING (Safe ESD in direction CLOSE)
1. Actuator operated to end position CLOSED via
standard controls (until limit switch in end position
trips)?
2. Switch compartment opened?
3. + 4. Torque switch CLOSE operated and safety
operation initiated for operated switch?
(Test button [1] turned in direction of the TSC arrow?)
Safe ESDa Safe ESDb
and
to 0 V (low)?
➥ Check actuator reaction:
Safety operation not initiated?
➥ Check SIL module signal behaviour:
No SIL fault signal?
SIL failure
output (NC contact) = open)
5. Safe ESDa and Safe ESDb
set to +24 V DC (high)?
6. Switch compartment closed?
☒ ✓ = 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.
