Manual Gate Arm Operation (Standard Feature)
NOTE:
DO NOT MANUALLY OPERATE GATE UNLESS POWER HAS FIRST
BEEN TURNED OFF! THERE IS POTENTIAL FOR SEVER INJUTY IF POWER
IS RESTORED WHILE MANUALLY OPERATING GATE.
All SG1420 Gates have the capability to be manually raised or lowered. The normal method to
manually raise or lower the gate arm’s position is to:
1)
Unlock the access cover.
2)
Set the ‘POWER’ Toggle Switch to ‘OFF’.
3)
Move the drive belt around by hand, thereby moving the gate arm either up or down as
desired.
Use care!
Having the hand caught between the pulley and belt is painful!
Manual Gate Arm Operation (Optional)
The SG1420 can be ordered with a manual crank to perform manual operation. The Gate’s top
cover is fitted with a plastic plug, which when removed will allow the crank assembly to be used
to rotate the special sheave on the motor shaft.
Drive Belt Tension
The drive belt requires periodic tension checking. Improper tension of the drive belt can result in
erratic gate arm motion. See Troubleshooting Section.
Maintenance
Good maintenance is essential to the long life of your Delta SG1420 Security Gate. Long,
trouble free operation is obtained by adhering to the following suggestions:
1)
Check belt tension every 60 days to control Gate over travel. Consistent tension will
allow the gate to stop in the same position every time.
2)
Adjust limit switches (See section above) for proper gate arm travel if extremes in
temperature are encountered. In cold weather, gear box lubrication will stop arm travel in
a shorter time. Lengthening the travel may be necessary. Conversely, in summer, hot
temperatures may cause the gate arm to over travel the desired position. Shortening the
travel can compensate.
CAUTION:
Do NOT attempt to adjust the limit switches with the power
on. Power switch must be placed in the ‘Off’ position before adjustments
are made.
3)
Service the gear box annually by draining old oil and refilling with clean Texaco
Vanguard oil or equivalent.
4)
Tighten all nuts, bolts, and screws on the Gate assembly every 60 days or as necessary.
5)
Wash and wax the Gate cabinet exterior, once a quarter, or as necessary to maintain the
bright gloss finish of your Delta Gate.
