SYSTEM TROUBLESHOOTING
Problem
Possible Solution
Gate opens a short
distance, then stops and
reverses.
•
Check the UL/Edge input on the gate controller.
•
Ensure limit LEDs are functioning properly.
•
Check for obstructions.
•
Adjust Force Settings.
Gate opens but will not
close.
•
Check the input LEDs. Any ON will hold the gate open and indicates a problem
with a keying device. Exception is “STOP”.
•
Check the external safety devices. Any activated safety devices will hold the gate
open and indicates a problem with the safety device.
•
Check limit LEDs. Orange LED indicates both open/close at same times. Check
limits for failures. Replace as necessary.
•
Check the loop detectors. Any activated safety devices can hold the gate open
and indicates a problem with the loop detector or ground loop.
Battery backup system
will not open gate upon
AC power outage.
•
Check if backup system is set to open gate automatically or requires an input to
open (Functions>Advanced).
•
Check batteries for proper voltage. Replace if necessary (Display>Battery Volt).
•
Check incoming Main DC Power (Display>Main Volt.).
Hard Shutdown (two
back to back obstruc-
tions) LED blinking, Buzz-
er sounds for 5 minutes.
Clear any obstructions from the path of the gate. Press RESET to clear (or hard
reset button).
Gate opens by itself.

Event programming has not been set to open the gate at a particular time.
1050 display shows
repeated “Nice Apollo
1050” when a button is
pressed.
Check battery voltage and replace if necessary
(Display>Battery Volt)
.
Gate moves in direction
opposite expected.
Reverse the actuators Red and Black motor wires connected to the 1050 control
board.
Limit LED glows green
when gate is closed, and
red when open.
Reverse the actuators Orange and White encoder wires connected to the 1050
control board.
