Maintenance and Troubleshooting SR-100i User’s Manual
Logic-Regulator Status LED’s
If a problem occurs with the SR-100i system, check all of the primary disconnect
fuses before proceeding. Also, check fuses F1, F2, and F3 in the power supply.
Be sure to check all fuses with an ohmmeter and replace any bad fuses.
The logic-regulator p.c. board controls all of the functions of the SR-100i system.
It has 13 LED’s which aid in troubleshooting the system. The LED’s illuminate
when a particular event occurs. Illuminated LED’s indicate the following:
