AM486 - Appliance module
The information on how to use a resistor to drop the voltage for the coil comes from Leonard Simms in New Zeeland (lgs@midland.co.nz) so if your house catch fire because of a modified appliance module, ask him why. The other modifications seem to be quite safe. Please don't try to sue him. I don't think it will work! Anyway, he said that the coil modification works, and the other modifications also corresponds to my general modification principles.
Change C1 from 0.68uF/250V to 0.33uF/400V. Change R1 from 100Ohm/0.5W to 220Ohm/1W. Change R2 from 330K/0.25W to 330k/0.5W. Change R5 from 330k/0.25W to 330k/0.5W. Change also C11 from 10nF/250V to 10nF/400V. This is the capacitor connected in parallel with a 2.2k resistor. Change the 130V MOV to a 250V MOV. If you use 240V use a 270V MOV. Add a resistor of 100Ohm/2W in series with one of the wires for the coil of the cam relay. Fix this resistor good and be sure is does not touch anything, it can become very hot. Use adaptors for the connectors on the input and on the output or just change plugs on your appliance to US (grounded) style. Compont number comes from my (Hans) drawings.
Comments from Hans:
I think that anobody who tries this should read my general modification principles and also print out the drawing to understand this better. Also don't start up a 10 minute X10 signal test from e.g. a TimeCommander on an address used by a module modified in this way. The Timecommander (Plus) will send an "on" every other second and an "off" every other. Beleive it or not, you can almost kill an original 220V module (110V?) in this way! At least they start to work badly and they smell bad after 5-10 minutes! And as a reference on how the components are marked and what color they have, look at the other modification files. For component numbers, print out my drawings. They seem to always use the same big, blue, capacitors and randomly use 1/4W and 1/2W for the 330k resistors. On 220V, use only 1/2W 330k resistor for the ones that go to the 220V.
