4. Start teach-in operation
- Switch on operating voltage
- Wait for self-test (STATE LED ashes for approx. 10 seconds at 15Hz)
- Teach-in operation starts (STATE LED ashes at approx. 1Hz)
- Wait for acknowledgment of the teach-in operation (STATE LED goes out after approx. 10 seconds)
5. End teach-in operation
- Remove jumper between J1 and J2
- For Manual start operating mode: start button must be connected
- For With feedback operating mode: feedback loop must be connected
- Interrupt operating voltage for at least 10 seconds
- Wait for self-test (STATE LED ashes for approx. 10 seconds at 15Hz)
6. Check all safety guards for effectiveness
9.2.1. Changing the conguration/new actuators
The evaluation unit can be re-congured as often as required. For this purpose you must proceed as per the rst teach-in
operation according to the section 9.2. Teach‑in operation on page 15. Faulty actuators can be replaced. Then again a
complete teach-in operation must be performed.
9.3. Functional check
After installation and any fault, the safety function must be fully checked. Proceed as follows:
WARNING
Danger of fatal injury as a result of faults in installation and functional check.
Ì Before carrying out the functional check, make sure that there are no persons in the danger area.
Ì Observe the valid accident prevention regulations.
1. Switch on operating voltage.
- The safety switch carries out a self-test.
The green STATE LED ashes for approx. 10 seconds at 15Hz.
The STATE LED then illuminates continuously.
The OUT and DIA LEDs do not illuminate.
2. Close all safety guards.
- The machine must not start automatically.
- The green STATE LED and the yellow OUT LED light up continuously.
3. Enable operation in the control system.
4. Open the safety guard.
- The machine must switch off and it must not be possible to start it as long as the safety guard is open.
- The green STATE LED illuminates continuously; the OUT and DIA LEDs do not illuminate.
Repeat steps 2…4 separately for each safety guard.
9.3.1. Self-test with test input TST
On electromechanical safety switches or magnetic switches, the function test can be performed by cyclically opening the
safety guard.
From category 2 according to ENISO13849-1 and in accordance with EN 60204-1 : 1997 (chapter 9.4.2.4), a function
test must be performed on the entire safety system on start-up or after dened intervals.
Testing of the internal function of the unit is not necessary because the device monitors itself in real time. Welding of an
output contact (relay output) is detected by the device at the latest the next time the safety guard is opened. A short circuit
in the output cable is not detected by the device.
In addition, the entire safety circuit can be tested without opening the safety guard. For this purpose, opening of the safety
guard can be simulated by applying 24 V DC to the test input TST.
