m EXPLANATION OF VISUAL FEEDBACK LED's
The AGS 2000 Full Systems Capability circuit board has been equipped with Visual Feedback LED's to simplify
installation and troubleshooting. These are small lights which are located directly beside the input terminals. These LED's
give visual information to the installer or service technician indicating what commands are going into the circuit board from
devices such as limit switches or from peripheral devices such as radio receivers or safety loops. There are also two LED's
which show output to the motor for both the opening and closing directions.
INPUT:
Limit Switch 1: This LED indicates that one of the normally open limit switches is pressed in and the gate is in the
open position.
Limit Switch 2: This LED indicates that one of the normally open limit switches is pressed in and the gate is in the
closed position.
Safety: This LED indicates that there is a closed contact between safety input terminal 4 and common.
Open: This LED indicates that there is a closed contact between open input terminal 5 and common.
Pulse Open: This LED indicates that there is a closed contact between Pulse Open input terminal 7 and common.
Stop: This LED indicates that there is a closed contact between stop input terminal 9 and common. Under normal
operating conditions this LED must be in the on condition in order for the system to function.
Close: This LED indicates that there is a closed contact between close input terminal 10 and common.
OUTPUT:
Motor A: For RIGHT SIDE OPERATION this LED indicates that the circuit board is delivering power to the motor
for the opening direction of travel. For LEFT SIDE OPERATION this LED indicates that the circuit board is delivering power
to the motor for the closing direction of travel.
Motor B: For RIGHT SIDE OPERATION this LED indicates that the circuit board is delivering power to the motor
for the closing direction of travel. For LEFT SIDE OPERATION this LED indicates that the circuit board is delivering power
to motor for the opening direction of travel.

m TRANSMITTER DOES NOT WORK
Check the battery inside of the transmitter and/or try another transmitter.
Make sure that the DIP switches
inside of the transmitter are set exactly like the DIP switches inside of the receiver.
Check to see which LED’s are
illuminated on the circuit board. For normal operating conditions the only LED’s that should be illuminated are the stop
input at terminal 9 and Limit Switch 1 input if the gate is in the fully open position or Limit Switch 2 input if the gate is in the
fully closed position.
If any of the input LED’s are illuminated on terminals 4, 5, 7 or 10, disconnect wires from that input
terminal that is illuminated until the LED is extinguished to determine which input device may be stuck in an on condition.
If it is the radio receiver that appears to be stuck in an on condition, check all transmitters to see if any of them are stuck
on.
Make sure that there is power (10 to 16 VDC) to the receiver on terminals 8 and 12 and make sure that the circuit
breaker button is pressed in.
If a click is heard while the transmitter is being pressed and there is no response from the
operator, check all receiver connections. (See page 15.)
If there is still no response, see GATE WILL NOT OPEN OR
CLOSE on next page.

m GATE TRAVELS TOO FAR OR NOT FAR ENOUGH
Adjust the gate sensitivity (See page 17). If the gate sensitivity adjustment is too sensitive, the gate may stop in
mid-travel.
It may be necessary to lubricate any mechanical parts on the gate including wheels and rollers and clean the
track of any debris.
Check the limit switch input LED’s on terminals 1 and 3 to see if either one is illuminated. If one of
the limit switch input LED’s is illuminated and the gate has traveled too far or not far enough, this indicates that the limits of
travel may need adjustment. Adjust the limits of travel (See page 11). This adjustment may change slightly as the chain
stretches due to normal wear and it may change dramatically if the chain has been re-tightened or the limit plate is
accidentally left unengaged with the limit nuts.
If the limit nut has traveled past a limit switch, check the limit switch and
all limit switch connections. (See page 19 or 20).
Watch the stop input LED on terminal 9 while the gate operator is
running and see if the LED flickers or extinguishes. This may indicate a faulty stop input device or a poor connection
between the stop input terminal 9 and common.
If the stop input LED on terminal 9 flickers or extinguishes check all
connections to the stop input device and/or replace faulty device.
