been having problems on a heidelberg press M#538909 installed in 96. Unit has a technotrans controler FKT-C-20000L-H-, tre31 controller and more cards that run 24v DC. Has 2 parts that get cooling from same cct. one that cools rolers(tempering), the other cools a batch tank with a water/alcohol solution(dampening). Before I got there 2 other companys had already been there and told them controler card hooped! They ended up changing card and still no luck. Each evap. cools water then circulates it to rollers and dampening parts on press. solinods that pump down the refrigeration were not getting signal, found flow switch fried on water circ. going to rollers. Jumped out switch reset, 1 solinoid now working. Problem is other not opening for the dampening portion of press. I have checked coil, it's good but machine seems to lock out because dampenig portion is out of set point range. When I get the solinoid open my pressures seem to be OK 60&235psig so i'm thinkin that somthings not set right in controller. Any help greatly apreciated.
