Summary of change:
I would like to know the specification for serial nr 6110. Simple tests (justified anyway, especially if ECU is old or paper lost). '''Steps:''' * make sure grounds are connected * '''Save config''' * disable output channels (good idea until the harness/app is known, and driven loads are verified, at least with simple Ohm measurement; eg between EC36/pin7 and EC36/23) What would be the target application ? '''How many IGBT ?''' * measure voltage between EC36/29 (or any other +5V potential above GND) and ignoutput after powerup (output not active) * 5 .. 5.5V measured => logiclevel output * 0V measured => power IGBT output ** (if uncertain, use a 1k..10k "pullup" resistor, parallel with the DVM; the DVM otherwise has a very high input resistance, 1M .. 10M usually). ** 1k Ohm resistor in series with LED (anode connected to +5V) makes a very good bench setup. ** If uncertain, that is very good time saving to see in action: PC soundcard => trigger, eg with "m231" aka 24-1 signal (disable sectrig first), and test all outputs in question (or those planned to be used) 1 by 1. ** IGBT outputs are off by default, only light up during dwell time (or if configured as other, eg. misc2 function, and turned on by parameters or by inverting). ** Logiclevel ignouts pull to GND by default, so appear ON if tested between output and +5V (appear OFF if tested between output and GND) ---- '''VR or HALL trigger ?''' Measure DC voltage, while '''connecting a 1k resistor between GND and ''' * '''EC36/27 primary trigger''' * EC36/13 sectrig DC voltage * 0.5 .. 2V means strong (eg. 2k7 .. 4k7) pullup (1.35V is usual) => HALL input * 0.1 .. 0.3V means weak (eg. 18k .. 27k) pullup (0.18 .. 0.25V is most usual) => VR input ** 0 .. 0.1V is also possible for sectrig VR ---- '''Injector type?''' '''must assume 30V voltage flyback, High-Z injector only''' * unless you know for sure that it has active flyback at this time. ** Even if it had active flyback 4 or 8 ch originally, perhaps it was removed if the history is untracked Will look more by orderID. What city and country is it currently in ?
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
