Force Control; Troubleshooting Leds - Chamberlain LiftMaster Professional SL585 Installation Manual

CONTROL BOARD PROGRAMMING AND FEATURES
(CONTINUED)

FORCE CONTROL

Set the force control pot such that the unit will complete a full
cycle of gate travel but can be reversed off an obstruction without
applying an unreasonable amount of force. On most operators
this will be around the middle of the range.
NOTE: For LED location refer to illustration on previous page.
DIAGNOSTICS (LEDS AND CODES)
There are three diagnostic LEDs. Two red LEDs (OLS, CLS) are
indicators for the open and close limits. The LEDs are illuminated
when the limit switch contacts are closed.
The third amber LED (DIAG) 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.
RELAY DRIVE TROUBLESHOOTING LEDS
There are 5 troubleshooting LEDs on relay drives K1 through K5. These LEDs will be illuminated when the microcontroller relay drive
is activated.
