Re: LTSpice Model for Photo Triac - VOM160

Hi Andy, Sorry for the incomplete upload. Learning woes I guess. Actually the one modified from the original circuit ran. I think because I didn't delete any text that was on the original schematic.
While the fresh? made one? wouldn't and has the error. So I got puzzled again what was going on. I actually did step 2 before but still it wouldn't run. I did not do step 3. So now I do both and wallah it runs!
Please would like to request one more help. How do I now permanently save the part that has already MOC3083 on it instead of? LED_TRIAC_ZCS, and what needs to be done so I don't have to add the directive? ?.lib MOC308x.lib? everytime I use this part?
Thanks and best regards, Eric

What you uploaded didn't include the symbol and library files.? We like to have all uploads be complete, so that they don't depend on other files elsewhere.
So I copied over the two files (LED_TRIAC_ZCS.asy and?MOC308x.lib) that I said you needed.
When I run "Heater-circuit-MOC3083_modified.asc", it won't run because that schematic tries to load "st_standard_snubberless_triacs_LTspice.lib" which isn't there either.? I don't think it's needed in that schematic, is it?? So then I copied that file over too, anyway.? Now when I run it, it runs without any errors.? Is this the one you said had an "Unknown subcircuit" error?
When I run "Heater-circuit-MOC3083-fresh drawn.asc" (after having added the symbol and library files), I get the error about "Unknown subcircuit".? The reason is because you forgot to do steps (2) and (3) that I described earlier.? The text immediately under the symbol needs to be changed to "MOC3083", and there must be the line to include the library file that has its subcircuit definition:
? ? .lib MOC308x.lib
Fix those two, then it should work.
Regards, Andy
