GL BOARD FEATURES
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 (1-6 pulses) to differentiate
between the different diagnostic codes.
