Table 26: 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. Switch compartment opened?
Safe ESDa Safe ESDb
3. and
set to 0 V (low)?
➥ Check actuator reaction:
Safety operation initiated?
4. Limit switch CLOSE operated until step 5.1 was
executed?
(Test button [1] turned in direction of the LSC arrow?)
➥ Check actuator reaction:
Safety operation stopped?
Safe ESDa Safe ESDb
5.1 and
set to +24 V DC (high)?
5.2 Actuator operated via local controls or from RE-
MOTE to end position OPEN and then to end position
CLOSED?
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.
11.2.6. Safe ESD reaction to "Forced limit seating in end position" (limit evaluation) – for actuators with
electronic control unit and limit switches
SQR 14.2
One of the following safety functions:
- Safe ESD function: "Safe CLOSING" (Safe ESD in direction CLOSE)
- Safe ESD function "Safe OPENING" (Safe ESD in direction OPEN)
"SIL seating" configuration
= Forced limit seating in end position"
Also valid for combination of SafeESD with Safe STOP.
