Summary of change:
First Let's start with the pinout of the VEMS unit [http://www.vems.hu/wiki/index.php?page=MembersPage%2FMikeLough Pinout] image Bench level Tester -------------------- Done, * TPS * 16 LED tester installed * 4 aux LEDs installed ** FP relay ** others not hooked up * WBO2 pump(+) - 100ohm - nernst - 100ohm - pump(-) * primary trigger in (60-2 wheel setup +/- 2Vpp (0vdc offset -1Vmin,+1Vmax) * secondary trigger hooked up but not in test setup. ---------------------- ''Current problem'' WBO2 setup Board is 3.2 returned unit WBO2 output readings hooked up to 100ohm test gnd -- pump(+) 4.83V gnd -- Nernst 4.38V gnd -- pump(-) 3.95V pump(-) --> pump(+) 0.886V Voltage between nernst and pump- is 0.43V instead of 0.45V. Acceptable. Might be caused by too low * main supply voltage (if < 10.5V) * wbo2_nernstdc_target * wbo2_pump_pid_ki (unlikely) I am reading about the setup in the manual, but I'll gladly take any suggestions. config setup has been tested from mt-027 supplied \mt-027\config (wintools upload) and from marcell's zipfile that uses a normal nernst ckt. excepts included here. ----------------------------- # Supplied w/ mt-027 wbo2_warmup_ramp=FA wbo2_warmup_target=FF wbo2_abs_limit=E4 wbo2_limit_maxt=A0 wbo2_fallback=60 wbo2_retry_t=06 wbo2_edgetime_corr=BA wbo2_edgetime_min=50 wbo2_ri_target=96 wbo2_nernstdc_target=8D # slightly increase this wbo2_pump_pw_zero=64 wbo2_calibration=AE wbo2_heater_pid_kp=46 wbo2_heater_pid_ki=10 wbo2_heater_pid_kd=1A wbo2_heater_pid_ilimit=80 wbo2_pump_pid_kp=40 wbo2_pump_pid_ki=2E wbo2_pump_pid_kd=08 wbo2_pump_pid_ilimit=84 wbo2_ri_confidence_scale=80 ----------------------------------- # from marcell;s zipped config file. wbo2_warmup_ramp=9C wbo2_warmup_target=FF wbo2_abs_limit=E4 wbo2_limit_maxt=A0 wbo2_fallback=60 wbo2_retry_t=06 wbo2_edgetime_corr=BA wbo2_edgetime_min=50 wbo2_ri_target=96 wbo2_nernstdc_target=9C wbo2_pump_pw_zero=65 wbo2_calibration=B8 wbo2_heater_pid_kp=45 wbo2_heater_pid_ki=11 wbo2_heater_pid_kd=1A wbo2_heater_pid_ilimit=81 wbo2_pump_pid_kp=15 wbo2_pump_pid_ki=4E wbo2_pump_pid_kd=00 wbo2_pump_pid_ilimit=FF wbo2_ri_confidence_scale=80 -------------------------------- Current setup as downloaded from mcd wbo2_warmup_ramp=A0 wbo2_warmup_target=FF wbo2_abs_limit=E4 wbo2_limit_maxt=A0 wbo2_fallback=60 wbo2_retry_t=06 wbo2_edgetime_corr=BA wbo2_edgetime_min=50 wbo2_ri_target=A1 wbo2_nernstdc_target=8F wbo2_pump_pw_zero=E7 wbo2_calibration=64 wbo2_heater_pid_kp=46 wbo2_heater_pid_ki=10 wbo2_heater_pid_kd=1A wbo2_heater_pid_ilimit=A0 wbo2_pump_pid_kp=30 wbo2_pump_pid_ki=01 wbo2_pump_pid_kd=00 wbo2_pump_pid_ilimit=E0 wbo2_ri_confidence_scale=80
