Safety Relay FAQ

Q: If a safety relay disconnects the circuit during use, is it a device failure or a dangerous factor detected?

A: Circuit breakage can be caused by many factors. First, check whether there are any dangerous factors, such as potential circuit accidents. If it is confirmed that there are no hidden dangers, the safety relay may be faulty. At this point, you can try restarting the relay. If the problem persists, you need to troubleshoot or replace the relay.

Q: What should I do if the safety relay output contact fuse?

A: The output contact fuse of safety relay, it is usually caused by a short circuit fault or overcurrent. At this time, the new fuse should be replaced and the circuit should be checked for short circuit or overcurrent problems to avoid similar faults from happening again.

Q: What is the difference between automatic reset and manual reset?

A: Automatic reset means there is no reset switch in the feedback circuit and the device starts automatically when the input is turned on. Manual reset means there is a reset switch in the feedback circuit, and when the input is open, the device will not start unless the reset switch is pressed. Manual reset is basically safer and it must be performed after all hazards have been cleared. Therefore, manual reset is used for machines and emergency stop circuits that personnel can enter, and automatic reset is used for machines that personnel cannot enter.

Q: What is the reason why the safety relay contacts cannot separate?

A: Failure separation of the safety relay contacts can be caused by mechanical bonding, welding, or cold welding. In addition, low contact capacity, heavy load, or changes in load characteristics can also cause failure to connect or disconnect the circuit. At this time, check the contact status and replace or adjust if necessary.

Q: How to adjust the operating parameters of the safety relay?

A: When adjusting the operating parameters of a safety relay, its technical parameters, such as contact thickness, open gap, overtravel and terminal pressure, should be measured first to ensure that all parameters meet the requirements of relevant regulations and working documents. Then, adjust the set value of the action parameter according to actual requirements and fix it with stop paint.

Q: What precautions should be taken when using safety relays in combination with other components?

A: When using safety relays in combination with other components, ensure compatibility and coordination between the components. At the same time, relevant safety regulations and operating procedures should be followed to ensure the safety and stability of the entire circuit system.
