TROUBLE SHOOTING AND MAINTENANCE PROCEDURES
WARNING - DISCONNECT BATTERIES AND AC POWER BEFORE
SERVICING ANY MECHANICAL OR MOVING COMPONENTS!!!!
BATTERY CHECKOUT-
slower. (Note: Batteries should only be checked when you are sure they have had adequate time to
fully charge). Turn off the AC power and run gate for 5 to 10 cycles while observing low battery
indicator LED D12. If LED 12 comes ON, batteries are too weak to function properly. If LED 12 does
not light, then voltage should be checked as they still maybe near failure. Correct voltage is
approximately 24.5VDC. (Note: If LED D12 does light, gate will open to conserve batteries in this test
or in a real power loss, even if mode switch 8 on S2 is off). Return of AC power will clear low battery
indicator. Correct charge voltage is 27.5 VDC with batteries not connected (adjustment is at R63).
GATE WILL NOT CLOSE
1) Check for any active inputs, AC power loss, AC power switch is off or weak batteries.
2) Check that batteries are connected properly.
3) Is switch S-3 in on position (this is manual open switch).
4) Check for S-2 switch number 8 is in on position and if AC power is lost, see LED D14.
5) Check LED D12, if lit and AC power is off, then batteries needs to be charged or replaced.
GATE WILL NOT OPEN
1) Check for AC power loss at D14 (check AC power switch) and that batteries are fully charged.
2) Check fuses and if inputs are wired correctly, test S-3 manual open switch.
GATE DEAD, NO OPERATION
1) Check LED D14 for AC power indication and check AC power switch is on.
2) Check LED D11 for Heart Beat pulses, if none and D14 (AC) & D5 (Brake) are on, then gate
has repeatedly sensed obstructions. Clear obstruction then clear with next new input.
3) IRD (D2) LED is flashing, MRT has expired. H1, H2 (Hall sensors) and clearance to magnet
on cam MUST be check for intermittent activation, failure to rectify may result in malfunctions.
(MRT is M aximum R un T imer that disables the gate if the magnet does not reach H1or H2).
Reset the AC and battery power to clear this once you have rectified the problem.
FUSE(S) ARE BLOWN, F-3 (10 AMP AC) AND / OR F-4 (15 AMP DC)
1) Check for shorts in wiring. If F-3 AC fuse is blown then batteries may also be weak or dead.
GATE CLOSES THEN REVERSES
1) See page 6 for IRD adjustments also check for obstacles in gate travel, trees etc......
2) Charge voltage to batteries too low, adjust at R63 . With batteries disconnected set to 27.5.
IRD OBSTRUCTION SIGNAL TO OTHER GATE NOT WORKING CORRECTLY
1) Remove connector at J3, obstruct arm, LED D13 should go off for a few seconds. This indicates
signal was transmitted. Be sure gates share a common ground (See master slave pg. 4)
GENERAL SERVICE
1) Belt loose or needs replacement, adjust with 4 bolts that support motor to allow 1/4 inch play.
2) Charge voltage for batteries should be 27.5 VDC with batteries disconnected. (set at R63)
3) Replace batteries with Yuasa, pn# NP7-12 , 7 amp hour 12vdc sealed lead / acid type.
. When the batteries become weak the gate will begin to run noticeably
"Warning- For Continued Protection Against Fire,
Replace Only With The Same Type And Rating Of Fuse".
