What to do if all LED off on Schaller Automation VN115/87plus EX Security Sensors?
If all LEDs are off on your Schaller Automation Security Sensors, begin by measuring the supply voltage. If that's not the issue, try activating the self-repair of the Polyfuse. If problems persist, replace the measuring head fuse. Also, check for any earth fault problems and as a last resort, exchange the measuring head.
What to do if supply voltage too high in Schaller Automation VN115/87plus EX?
If the supply voltage is too high on your Schaller Automation Security Sensors, first measure the supply voltage. If the issue persists, consider exchanging the measuring head.
How to fix defective reset button on Schaller Automation VN115/87plus EX Security Sensors?
If the reset button on your Schaller Automation Security Sensors is defective, first try to eliminate any blocking that might be preventing it from working. If that doesn't solve the problem, you may need to exchange the measuring head.
How to fix negative pressure out of range on Schaller Automation Security Sensors?
If your Schaller Automation Security Sensors are showing a 'Negative pressure out of range' error, you can try the following: 1. Adjust suction pressure. 2. Exchange the air filters. 3. Clean the fresh air bores. 4. Check the suction system. 5. Exchange the bellows. 6. Exchange the filter cartridge. 7. Exchange the measuring head.
What to do if electronics temperature too high on Schaller Automation Security Sensors?
If the electronics temperature is too high (over 75°C) in your Schaller Automation Security Sensors, remove or turn away any ambient heating components. You can also install metal heat shields to protect against radiation.
What to do if ambient temperature too high on Schaller Automation VN115/87plus EX?
If the ambient temperature is too high (over 70°C) for your Schaller Automation Security Sensors, you should remove or turn away any ambient heating components. Additionally, consider installing metal heat shields to protect against radiation.
How to clean dirty optical sensor on Schaller Automation VN115/87plus EX Security Sensors?
If the optical sensor on your Schaller Automation Security Sensors is dirty, you should clean the infrared filter.
What to do if electronics temperature too low on Schaller Automation Security Sensors?
If the electronics temperature is too low (below 0°C) in your Schaller Automation Security Sensors, remove any ambient cooling components that may be causing the issue.
What to do if ambient temperature too low on Schaller Automation VN115/87plus EX?
If the ambient temperature is too low (below 0°C) for your Schaller Automation Security Sensors, remove any ambient cooling components that might be causing the problem.
