Author Topic: CP2215 Light Off State Caused by Emergency Stop Ronn Mesias Film Handler Posts: 9 From: Kuwait Kuwait City Registered: May 2014 posted 04-18-2017 12:32 PM                     Hi Film-Tech Team, a week till now we are experiencing a explainable lamp off at random time in one of our cp2215 projector. Hope a guide or hint where we can start to find the root cause of this issue.Thanks appreciate in advance. below is the message error: 0530 Light Off State Caused by Emergency Stop.

If that's actually used in your installation I would suspect teh fire alarm relay or wiring. If not, the link is pretty solid but check the screws? A dodgy connection to wherever it connects to is a possibility, I expect that's the PIB but I'm not willing to check schematics. Reseating all the boards would be worthwhile. I don't know of any other emergency stop, but there could be a serial/network command to force one. I'm equally unwilling to search the command list to see.  |  IP: Logged Peter Bua-ay Film Handler Posts: 7 From: Deira Dubai, UAE Registered: Oct 2016 posted 04-19-2017 12:27 AM                     Hi Ron, If fire alarm is shorted in the unit and you've done enough troubleshooting and still didn't find anything, replaced the PIB. This issue happened to me before and been doing a lot of troubleshooting and found nothing up until replacing the PIB. Try to run the PIB FIT if you have and see if PIB is ok.  |  IP: Logged
