Author Topic: Xetron XH-2000 lamphouse wont strike?!?!?!?!? John Westlund Expert Film Handler Posts: 204 From: Burney, CA, USA Registered: Jun 2001 posted 01-13-2002 01:07 AM                     I posted a question some time back about a problem with the autostrike on our Xetron XH-2000 lamphouse. I have changed the circuit breaker and the autostrike relay and it still wont strike. The bulb is a 2000 Watt Osram with about 200 hours on it now. It was just changed not long ago but was not the problem. It needed to be changed anyway. Thanks for all your help.

Almost to the end of the volt meter to 150v.  |  IP: Logged Rick Long Jr Expert Film Handler Posts: 211 From: Toronto, Canada Registered: Jul 2000 posted 01-13-2002 08:04 AM                     Some lamps have a potentiometer in the autostrike circuit to control the voltage going to the relay. It's usually right next to it. You could try adjusting it. Just be careful that if it does strike, the ignitor stops igniting once the bulb is lit. If it doesn't turn the pot back a bit until it does. This is assuming that the ignitor works properly with the emergency strike button.  |  IP: Logged Don Sneed Master Film Handler Posts: 451 From: Texas City, TX, USA Registered: Aug 2001 posted 01-13-2002 10:48 AM                        John, when you say will not strike, do you mean in auto and manual or just in autostrike, if only in autostrike, that changes things to diagnose...  |  IP: Logged Bob Maar (Maar stands for Maartini) Posts: 28608 From: New York City & Newport, RI Registered: Feb 2001 posted 01-13-2002 11:48 AM                        John, If you are having problems call our engineering department at 1 800 526 0722 and speak to them about the problem.

The bulb ignites as soon as the manual strike button is pushed.  |  IP: Logged John Walsh Film God Posts: 2490 From: Connecticut, USA, Earth, Milky Way Registered: Oct 1999 posted 01-13-2002 03:37 PM                     Rick's suggestion about the potentiometer is a good possiblity. After you replace the autostrike circuit breaker and relay, there's not much left in the circuit! (Considering it lights with the manual button.) Check for loose wires, or poorly crimped lugs where the wire looks like it's in, but is loose.  |  IP: Logged
