DIAGNOSTICS (LEDS AND CODES)
There are three diagnostic LEDs. Two red LEDs (OL, CL) are indicators for the open and close limits. The LEDs are illuminated when the limit switch contacts are closed.
The third amber LED (DIA) is used to blink out diagnostic codes. The number is the count of the number of times the LED is on in an 8 second period. The LED is on for approximately 1/2 second and repeats every second until the number is reached. There will be a pause following each pulse cycle
