Safe Esd Reaction To "Motor Protection (Thermal Fault)" Signals - AUMA SQ 05.2-SQ 14.2 Manual

Part-turn actuators
SQ 05.2 SQ 14.2/SQR 05.2
Table 23: 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?
2. Motor operation locked?
3. Safe ESDa and Safe ESDb
set to 0 V (low)?
➥ Check SIL module signal behaviour:
SIL fault signal within 4 seconds?
SIL failure
output (NC contact) = closed)
Safe ESDa Safe ESDb
4. and
set to +24 V DC (high)?
5. Motor operation lock removed?
☒ ✓ = 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.

Safe ESD reaction to "Motor protection (thermal fault)" signals

Table 24: Proof test checklist
Configuration
SIL motor protection active
1. Is actuator in mid-position or at sufficient distance
from the end positions?
2. Selector switch in position 0 (OFF)?
3. Simulation value Thermal test selected under Proof
test (motor prot.) parameter M1021 (required user
level: Specialist (4))?
Display indicates: CMD0078 Thermal test ○
(white dot)
Safe ESDa Safe ESDb
4. and
set to 0 V (low)?
➥ Check actuator reaction:
Safety operation initiated?
5. Motor simulation activated via push button Ok?
Display indicates: CMD0079 Thermal test ●
(black dot)
➥ Check actuator reaction:
Safety operation stopped?
➥ Check SIL module signal behaviour:
SIL fault signal?
SIL failure
output (NC contact) = closed)
Safe ESDa Safe ESDb
6. and
set to +24 V DC (high)?
7. Simulation reset or simulation menu exit and select-
or switch reset to initial position?
☒ ✓ = 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.
