You may not be getting enough exhaust pull, so the cooling modules over temp. Try swapping blower motors to isolate that before buying one. STANDARD AIR OPERATION: - Load-end: 150 cfm (255 m3/hr) at the 4� (102 mm) stack (minimum requirement) - Unlo

Thanks This error only occurred with one oven profile with the reflow zone temperature set at 270�C. Perhaps it really has to do with the exhaust pull as the oven is operating very near its temperature limit with this profile. I will check that. Tha

Hello all, I am having difficulty with an OmniExcel 10 oven. Zone 5 upper will not hold setpoint = 165C (it typically runs ~10C higher). Here is what I know: 1. The machine is not turning on zone 5 heat when temp is too high. 2. Zone 5 lower is

The main problem I am having is getting the Rising slope 1-3 degrees. If I slow the conveyor down then I have too long of a reflow and if I speed it up then my ramp rate is too high. I was not sure if I need my first zones at a low temp or higher t

I have seen a lot of discussion recently regarding reverse spike and double spikes in the reflow profiles of ovens. This is where a zone other then the last zone is the peak temperature, or where the last 2 zones have the same setpoint. Anyone have

During production the temperatures on the last 3 zones are approx. 20F higher than the setpoint. The other zones are operating within spec. We checked power, I/O, SSR's, thermocouples, and exhaust, but the issue remains. We did not check resista

The "marketing geniuses" of the world are now touting lead free ovens, lead free irons, and even lead free smocks, heel straps, and even G-Strings! Bottom line is - ya just gotta get it hotter, stupid! There's nothing "RoHS" about equipment besides

According to Quad data sheet, the max process temp on a ZCR oven is 310C. I am taking a guess that the "Critical Temperature" message may be Quad's way of saying that you have entered to high of a setting. Try bringing the setpoints to something belo

Ah, I have 3 of these ovens. Not bad ovens at all. You mentioned a PLCC 64. Is this part having the delta T problem? If so, that seems odd. Without knowing your exact set-points, you could pump in more heat up front. Change blower speeds to hig
