Author Topic: CNA-100 Automation problem Mike Lauber Film Handler Posts: 19 From: Fond du Lac, WI, USA Registered: Nov 2002 posted 07-28-2003 11:24 PM                     When I start the movie on one of our projectors using a CNA-100 automation system, the bulb will light and changeover will open, but the motor does not start. I know I should swap or replace the relay, but where do I find this relay in a wall-mounted CNA-100?

Does the motor start via the manual switches on the front panel? The relay in question is K1 found on pg 21 in the manaul. THe manual can be downloaded in the manuals section of the website. Just under that relay is a 10 amp slo blow fuse that I would check first.  |  IP: Logged Mike Lauber Film Handler Posts: 19 From: Fond du Lac, WI, USA Registered: Nov 2002 posted 07-31-2003 02:02 AM                     The motor does start fine using the switch on the front panel. I found the proper relay and tried swapping it with a different one on the board, and also tried swapping it completly with a different relay from another projector. Everything worked fine every time but that motor, so it's not a relay problem. I will check the fuse tomorrow, but the lamp and motor are on the same relay, so if the fuse was blown, how would the lamp automation be working correctly?
