MODEL SG1420 SECURITY GATE

General

The Delta Scientific Corporation Model SG1420 Security Gate is a heavy-duty unit designed to

meet the many needs of restricted traffic control. A large array of control modes are permitted,

including auto/manual operation in conjunction with local or remote pushbutton stations, timers,

radio controls, vehicle loop detectors, infra red detectors, ticket spitters, card readers, coin or

token devices, and computerized electronic tag systems. These devices may be used

independently or in combination. In short, any device which can provide a contact closure may

be used to vend or reset the Gate.

Safety

The Model SG1420Security Gate is equipped with an electric motor driving the gate arm

through a vee-belt/gear box system. Keep hands and fingers away from the unit interior when

power is on. Shut power off before adjusting limit switches or belt tension. Wiring to the terminal

strip should be made by a competent electrician according to the NEC (NFPA 70) and

applicable local codes.

Installation

The Model SG1420 is packed in a reinforced cardboard carton with an inner poly bog to guard

against moisture. Do not stack cartons or leave out in the elements until ready to set. Gate

model number and accessories are marked on carton top.

The SG1420 is to be located on a solid, non-combustible surface, such as concrete. Mark the

Gate location from the architect’s drawings. Conduit for the Gate motor and controls must be

brought to the stub-up area within the Gate'’ bottom opening (shown above). Foundation bolt

location can be marked from the Gate itself or from a template (Delta P/N D03180)

1) Use a masonry drill to provide the holes for the mounting bolts (4 – 3/8” X 4” long). If

appropriate for your application use lag shields (not provided).

2) Relocate the Gate and install the lag bolts using a flat and lock washer on each.

3) Locate gear box breather vent and remove plug. Vent hole faces upwards when the box

is in operation.

4) Install Gate Arm.

Wiring

As indicated above, the Gate will function using a wide variety of control inputs. Consult the

architectural plans for the required control functions, then refer to the specific Delta Scientific

Application Guide that covers that function. Common to all hookups:

1) Standard Power input is 120/1/60 VAC for Gate Motor and control power. The SG1420

may be ordered from the factory equipped to operate at 240/1/50 also. Conduit should

be run from below grade to the center stub-up area as shown in the installation drawing.

Field wiring connections are terminated at terminals L1 (hot) and L2 (neutral). Other

input voltages are available, and must be selected at time of order. The unit should be

grounded at the provided terminal (green).

2) Switch function:

a) Gate Auto-Manual: With the Power ‘On’, switching the Auto-Manual switch to

‘Manual’ will vend (raise) the Gate. To reset the Gate, switch Auto-Manual to

‘Reset’ position momentarily.

b) Heater On-Off –Auto: Gate may be optionally supplied with a 60 watt heater to

guard against condensation on the gate interior surfaces and to provide some

heating to reduce gear box lube oil viscosity in extreme cold. We suggest that the

heater switch be placed in the ‘Auto’ position at all times.

Limit Switch Adjustment

The Limit Switches are preset at the factory for standard operation across a level lane. The limit

switches are adjustable to allow gate arm travel adjustments, where necessary.

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. The

directions indicated below are made when viewing the Gate from the gate arm

side, Gate raise direction is clockwise (CW), Gate lower direction is counter-

clockwise (CCW).

1) To adjust the gate arm for more downward travel, loosen the thumbscrew on the down

limit switch cam and rotate slightly CW. Tighten screw, turn Power switch ‘On’ and check

by operating the Auto-Manual switch. Turn Gate ‘Off’ and re-adjust as necessary.

2) To adjust the gate arm for less downward travel, loosen the thumbscrew on the down

limit switch cam and rotate slightly CCW. Confirm as above.

3) To adjust the gate arm for more upward travel, loosen the thumbscrew on the up limit

switch cam and rotate slightly CCW, Confirm as above.

4) To adjust the gate arm for less upward travel, loosen the thumbscrew on the up limit

switch cam and rotate slightly CW. Confirm as above.

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.

Troubleshooting

If Gate fails to move:

1) Check Gate ‘Power’ switch. Switch must be in the ‘On’ position.

2) Check thermal overload on motor. If overload is tripped, reset by pushing trip button. If

motor is hot, let it cool before trying to reset.

CAUTION: Power switch should be in the ‘Off’ position when resetting the

thermal trip to prevent hands from being caught in the drive belt pulleys if

motor should happen to start on reset.

3) Check circuit breaker/disconnect switch feeding the Gate. Reset as necessary.

4) If there is power to the Gate (120/1/60 at terminal 1 and terminal 2):

a) Try switching the ‘Auto-Manual’ switch to ‘Manual’. The gate arm should go up. If

not, turn Power switch ‘Off’ and disconnect Gate at the Main. Check all electrical

connections (terminals and screws) for tightness. If Gate still will not function

when power is restored, call factory for assistance.

i) If Gate functions on ‘Manual’ but does not respond to vend or reset

signals; check control devices and detectors. When possible, exchange

known good components for suspected ones.

ii) If control devices and detectors are proved OK, the field wiring or

harnesses are to be suspected. Call factory for help.

b) If Gate runs but cycles up and down without stopping:

i) Check limit switch adjustment per the above instructions.

ii) If the limit switches are in their proper location, at least one switch is likely

failed. If the Gate runs on with the Auto-Manual switch in the ‘Manual’

position the UP limit switch has failed. If the Gate runs on in the ‘Auto’

position the DOWN limit switch is failed.

If gate moves erratically:

Erratic gate motion requires the drive belt tension to be checked. Open the SG1420’S’s door

and inspect the drive belt for looseness or excessive wear. If the belt appears worn or frayed, or

if the belt appears loose, first: remove Electrical Power to the gate and second, tighten or

replace the belt with a new one. To remove or tighten the belt, first loosen the Electrical Motor

mounting nuts slightly and pull the motor away from the Gear Reducer, then tighten the

Electrical, motor mounting nuts, thus tightening the drive belt.

Power Loss

The Delta SG1420 can be opened or closed in the event of a power outage by the following:

CAUTION: Power switch should be in the ‘Off’ position when manually operating

the gate to prevent hands from being caught in the drive belt pulleys if motor should

happen to start if power is restored.

1) Manually pull the drive belt around until the gate is in the desired position. Use Care!

Drive belt-pulley is a pinch point!

2) Turn Auto-Manual switch to ‘Auto’ and the Power switch to ‘On’. On power resumption,

the Gate will automatically resume powered operation.
