    What to do if 3M Detection System 3500 has no alarm, counter, or power indicator?

      If the 3M Industrial Equipment shows no alarm, no mechanical counter, and the red power indicator is off, first check if the power cord is properly plugged into the receptacle. If not, plug it in. Next, ensure that the facility circuit breaker hasn't tripped and reset it if necessary. Also, verify that the key switch on the Electronics Enclosure is turned to the 'ON' position. If the issue persists, replace the fuse in the power entry connector. If none of these steps resolve the problem, it may indicate a system failure, and you should place a service call.
