Saturday was 3 days ago. Did you go? What did you find?

Deju vu, all over again. Ran into this several years ago, when the canopy lights came on, all probes went off line. They were printing tank monitor info on the Ruby shift report,(about 9 p.m.) as the TLS printer had crapped out some time back. Everyone that went to the store found no problem. cool

Sorry for not getting back to you guys sooner. Last trip to site revealed that what the owner referred to as "canopy lights" were really a circuit of about 12 8" fluorescent fixtures under the eaves of the building. When you turn on the switch for these lights, the tank monitor shows "probe ouy" and remains so until the lights are turned off. I verified that they were not on the same circuit as the tank monitor. All of the bulbs are working but I told him to unwire one ballast at a time and try the lights again. I told him not to reconnect any ballast until he goes through them all to rule out the possibility of more than one ballast emitting inteference. he is a handyman and wanted to do this himself to save a few bucks. I have not heard back from him yet. will soon drop in and check on him.

8" lamps? That's small. :)
This is my signature. There are others like it but this one is mine.
