What to do if my SICK STR1 Switch has no voltage supply?
If your SICK Switch has no voltage supply, you should: * Check the voltage supply. * If the light emitting diodes do not light up even if a voltage supply is present, replace the safety switch. * Check OSSD 1 and OSSD 2 for short-circuit downstream of 0 V or 24 V DC, or between one another. * Check cabling for damage. Remember, there must be a dual-channel configuration.
What to do if my SICK Switch has an external fault?
If your SICK Switch indicates an external fault, take these steps: 1. Isolate the faulty sensor and check it separately. 2. Check the wiring for cross-circuits and short-circuits. 3. Switch the voltage supply off and on. If the fault persists, the sensor is likely defective and should be replaced.
What to do if my SICK STR1 has an internal fault?
In case of an internal fault with your SICK Switch: 1. Isolate the faulty sensor and check it separately. 2. Check the wiring for cross-circuits and short-circuits. 3. Switch the voltage supply off and on. If the fault continues, the sensor is defective and needs replacement.
Why did the teach-in sequence fail on my SICK STR1 Switch?
The teach-in sequence for your SICK Switch might have failed because: * The actuator was removed from the response range too early. * The voltage supply was not isolated in a timely manner. To resolve this, try teaching in the actuator again.
What to do if the maximum number of actuators has been taught in on my SICK Switch?
If the maximum number of actuators has already been taught in on your SICK Switch, it is not possible to carry out another teach-in process.
What to do if an actuator that has already been taught in needs to be taught in again on my SICK STR1 Switch?
It is not possible to teach in an actuator again if it has already been taught in on your SICK Switch.
