l
No objects should completely occlude the target.
Starting conditions
l
Machinery switched off (Safe condition)
l
Inxpect SRE 200 Series configured to fulfill the access detection safety function
l
Detection signals monitored via digital outputs or safety Fieldbus (i.e., PROFIsafe or FSoE)
Test setup
The following tests aim to validate the sensor’s performance for the access detection safety function.
In stationary applications, all the tests share these parameters:
Target type Human
Target speed In the range [0.1, 1.6] m/s ([0.33, 5.25] ft/s), with particular attention to the minimum and the
maximum speeds.
Acceptance
criteria
The system reaches the safe state via digital outputs or Fieldbus when the target accesses
the area during the test.
In mobile applications, all the tests share these parameters:
Target type Human
Machinery/Vehicle
speed
l
For detection distance less than or equal to 4 m (13.12 ft):in the range [0.1, 3] m/s
([0.33, 9.84] ft/s), with particular attention to the minimum and the maximum
speeds.
l
For detection distance greater than 4 m (13.12 ft): in the range [0.1, 2] m/s ([0.33,
6.56] ft/s), with particular attention to the minimum and the maximum speeds.
Target movement Stationary
Acceptance criteria The system reaches the safe state via digital outputs or Fieldbus when, during the
movement of the machinery/vehicle, the sensor’s field of view reaches the target.
Validation test
The validation procedure of Inxpect SRE 200 Series is reported below:
1. Identify the test positions, including those locations where the operator could access during the
production cycle:
a. boundaries of the dangerous area
b. intermediate points between sensors
c. positions that are partially hidden by existing or presumed obstacles during the operating
cycle
d. positions indicated by the risk assessor
2. Check that the corresponding detection signal is active or wait for its activation.
3. Perform the test according to the test setup previously defined, moving toward one of the test positions.
4. Check that the test acceptance criteria previously defined are fulfilled. If the test acceptance criteria are
not fulfilled, see "Troubleshooting validation" on page81.
5. Repeat steps 2, 3, and 4 for each test position.
8.5.3 Validation procedure for the restart prevention function
The restart prevention safety function must be operative, and the following requirements must be fulfilled:
l
The person must breathe normally.
l
No objects should completely occlude the person.
Starting conditions
l
Machinery switched off (safe condition)
l
Inxpect SRE 200 Series configured to fulfill the restart prevention safety function
l
Detection signals monitored via digital outputs or safety Fieldbus (i.e., PROFIsafe or FSoE)
Test setup
The following tests aim to validate the performance of the sensor restart prevention safety function.
