difficulities with JLD633 controller
Posted: Mon Mar 01, 2010 5:32 am
After i have struggled getting through the manual for the XMT63X manual (closest one available) i have yet to get this controller to operate correctly. i have programmed the 16 step profile for firing my ceramic and seem to be having incorrect temperature readings going into the controll unit. i am using a type K thermocouple that i have checked with my fluke/thermocouple module as well as tried other thermocouples and still get wrong temps. when i should be reading room temperature (70F) i am reading (88F) on my controller input. i even tried braided shielding on my thermocouple wire which the signal looks clean on my oscilloscope.
i ran my program on my kiln and thought at first that things were going well until the input stayed around the 350F mark and wouldn't continue to rise. the unit stayed on trying to meet the demands of a higher SV point. i checked with another thermocouple device (with the same thermocouple itself) and my kiln was indeed increasing in temp (it was 2000F). so i for sure have input problems with this unit.
can anyone provide any help or tell me what is either wired wrong or missing in the setup of this controller? i am extremely frustrated. thanks.
