Typical High Power Relay:
-DCI1 used to trigger another Higher Power relay.
A few other important notes:
It is recommended that all external connections be fused for safety, especially
if you are connecting to 120VAC line voltage. Please choose the correct fuse
size for your individual application. Proper fusing is critical to the safe opera-
tion of your kit, please take the time to properly insulate any high voltage or
current contacts made externally to your unit.
TROUBLESHOOTING GUIDE
If your ICI does not work at all, recheck the following:
•
correct orientation of VR1 and U1 (see PC board layout diagram).
•
You should be able to measure the voltage on the input and output termi-
nals of voltage regulator VR1. The input should be whatever the supply
voltage is specified at, while the output should be 5 VDC +/- 5%.
•
correct polarity of all electrolytic capacitors.
•
correct orientation of diodes D1 – D6
•
all solder connections
