5. Activating the system: A momentary connection between activation inputs and ground
(GND) is how the system is activated. At the upper left and bottom right of the board are
terminals marked INP or INPUT. These terminals - when momentarily shorted to ground
(GND) - will open, stop and close the gate with each activation. The button on the side of
the box (swing gates ONLY) is connected to these terminals and may be used to activate
the gate when the key is in the horizontal position. On our newest boards there is an
"OPERATE" button at the upper left area of the board that may be used in the same
manner.
6. HARD SHUTDOWN: If the system has encountered an obstruction two times before fully
opening or closing – the HARD SHUTDOWN LED (upper right of board) will begin
flashing – indicating a Hard Shutdown situation. Check to see that any obstructions are
removed from the gates path and then press the "HARD SHUTDOWN RESET" button to
restart the system.
7. Operator Orientation and Wiring: To verify the system is wired properly, position the gate
mid-way open and then connect the MASTER plug to the EMERGENCY BYPASS
receptacle. The gate should immediately begin opening. If the gate closes – reverse the
RED and BLACK motor leads coming from the board. Then, with the main harness
connected to the MASTER receptacle and the LEDs enable... Position the gate fully
OPEN – the OPEN LED should be lit. If it is not, adjust the rotating collars until the
OPEN LED is lit. (Note that the other collar is for the CLOSED position) Then – position
the gate fully closed and do the same process with the other rotating limit collar.
8. Dual Gate Systems: Test dual gate systems individually. Turn program switch #3 ON
(disables SLAVE side of board) and test actuators one at a time using MASTER side of
board only. Confirm proper operation of each actuator. If both test 100% - then test
together by connecting both actuators and turning program switch #3 to the OFF position.
9. EMERGENCY BYPASS: At the bottom left of the board is the EMERGENCY BYPASS
receptacle. Plugging the operator harness into this receptacle will OPEN the gate ONLY!
It is intended to open the gate(s) should other methods fail. Note that if the motor draws
more than 15 amps of current the fuse above the receptacle will blow. Also, the gate
operator will not stop by its self at the open position. The plug must be removed to stop
the gate. (This is also a handy way to test that the current consumption of the motor is
within the normal limits)
10. Manual Opening: Should it be necessary – the 3500/3600 systems may be opened
manually by flipping the toggle switch beneath the motor drive to the OFF position and
then pulling the articulating arms away from the gate where they connect mid-way
between the gate and the operator. Once the arms have been pulled open partially – the
gate may be pushed open and closed at will. The toggle may be turned back ON and the
system activated at any position without mis-adjustment to the limits.
11. FIRMWARE: In the upper right area of the board there is a micro-processor that has a
white label on it. This is the "FIRMWARE" of the system. Currently (May 2005) we are
using firmware version V31.00.02. For troubleshooting versions of the firmware earlier
then V31.00.00 consult your original instructions that were included with your system.
Systems that are out of warranty may be upgraded to newer version firmware for a
nominal fee.
