When any part of an electronic device fails, the main goal is to troubleshoot and repair the failure so that the device can resume work as soon as possible. If this equipment belongs to a link in the machinery monitoring system, this goal will become even more important.
The composition of the 3500 monitoring system is mainly composed of two parts: the 3500 frames and the eddy current sensor system. If any part fails, the normal operation of the 3500 monitoring system cannot be guaranteed, so that the equipment vibration data cannot be measured reliably, and the stable operation of the equipment cannot be protected, resulting in major risks to the safe production and operation of key equipment.
The first indication of failure of the 3500 monitoring system is the OK Relay (I/O module of the frame interface 3500/22M) that is normally energized. However, OK Relay is a warning of hardware, software, or power failure of the entire framework, and cannot prompt specific fault diagnosis information. It just means that there is a problem with the 3500 monitoring system.

However, the status of the lights on the front panel of the frame module can provide some useful information about the status of the 3500 monitoring system.
