CYCLE COUNT
* First, note the current Aux Relay switch positions. To determine the
actual cycles that the gate operator has run (in thousands), set all three
Aux Relay switches to the ON setting for Aux Relay 1. The Expansion
Board’s 1, 2, and 3 LEDs will blink out the cycle count, with 1 LED
blinking 1000’s, 2 LED blinking 10,000’s, 3 LED blinking 100,000’s, and
simultaneously all three LED’s blink 1,000,000’s (e.g. 1 LED blinks 3
times, 2 LED blinks 6 times, and 3 LED blinks once. Cycle count is
163,000.). Cycle count displayed is between 1,000 and 9,999,000
cycles. After servicing, set Aux Relay switches back to their appropriate
positions. Cycle count cannot be reset or changed. If under 1,000
cycles the 1, 2, and 3 LEDs will turn on for 10 seconds, then turn off.
NOTE:
The expansion board will flash the cycle count 3 times then all the
LEDs will turn on solid for 10 seconds then turn off.
