Sure! Let’s start by checking a few things. Firstly, ensure that the power source to the HRL-LF is functioning properly. Sometimes, issues can arise due to power fluctuations or outages. Next, inspect the wiring connections to see if there are any loose or damaged wires. Additionally, verify that the device is properly programmed and configured according to the manufacturer’s guidelines. If these steps don’t resolve the issue, it might be a good idea to contact System Sensor’s technical support for further assistance.
