hello,
I have the following problem with a kit K8028.
Switch on: self-test is successful; green LED4 illuminates
programming is successfully: lights program number 3 - LED1 and LED2 illuminates
Start (press SW1): lamp flickers, LED5 illuminates, LED2 illuminates
After about ca 1 second
lamp illuminating not, LED1 blinks 7 times
Check when selftest is running, LED 4 -> 3 -> 2 -> 1 is illuminates.
7x flash -> TRIAC can not conduct, maybe load not correct (connected) or K8028 hardware problem.
Check TRIAC,R10,circuits with and arround T1 and T3.
test the kit with a normal 60W lamp first, if still.
If still fail -> return the kit via your dealer for repair.
