<p class="MsoNormal"><span style="font-size:11.0pt;mso-fareast-language:EN-US">No schematics but we’ve had a few failures on these over the years and it is usually the thyristor modules which you should be able to replace with off the shelf units. Sometimes
they go bang with a good noise. They are not that complicatedly internally with regards to power electronics as I recall.. The PLC drives the thyristor modules on 3 phases, one per bank of lamps either via manually set power or as part of a sensed feedback
loop. On the power side I do not think there is much else to check. Make sure your banks of lamps meter out correctly when disconnected from the supply also I guess.

the vendor and they have been helpful with suggestions for troubleshooting but have not been able or willing to provide electrical schematics. I am popping a couple of breakers when I try to heat the system and really need these schematics to do any significant
diagnostic work. Does anyone have these drawings that they would be willing to share? We bought this system used and only have an operations manual.<o:p></o:p></span></p>
