CONTROL BOARD PROGRAMMING AND FEATURES
MOTOR LEARN FUNCTION (FORCE PROFILE)
This function is preprogrammed at factory. If either board or
motor is replaced, the controller will need to be programmed to
“LEARN” the specific motor RPM profile of your operator. Switch
“S3” is provided for this. This is important for accurate force
control. Failure to do so may result in improper and unsafe
operation.
To learn the motor:
NOTE: Motor Learn must be performed in stand alone mode.
1. The operator must remain attached to the gate throughout the
entire process.
2. Press the motor learn button. The yellow LED should start to
flash rapidly.
3. Install a jumper on either the hard open or the hard close input
terminals. The motor will run for a few seconds and then stop.
If the LED goes out the motor is learned. If the unit activates a
limit before completing the learn or some other error occurs,
the LED will go back to on continuously. If this happens, try
learning while running in the opposite direction.
NOTE: It is important that the jumper is in constant contact
while the gate is moving in learn mode.
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.
