OPERATION
1. Input Voltage warning light green LED - Indicates
that the machine is on and input voltage is within
acceptable range.
2. Thermal Shutdown Light (yellow LED) - Indicates
thermal over load or output disabled for incorrect
supply voltage.
•With the "Yellow LED" on, and an alarm code blink-
ing on "Digital Display Item 6" (see Troubleshooting
