ENTRANCE GATE INSTALLATION AND SETUP
a. Manually (no power to the mechanism):
i. With the gate arm in the horizontal position, install the lock bar onto the ½" hex
ii. Open the test links on Battery Terminals 4 and 5 to remove power to the
iii. Using the lock bar, hand crank the mechanism to the vertical position per
iv. Once the gate is in the vertical position, engage the slot in the lock bar with the
b. Automatically (power is applied to the mechanism):
i. Apply 12 VDC to the battery input to terminals 4 and 5.
ii. Apply 12 VDC to the Gate Control terminals. The gate arm will raise to a
iii. Install the lock bar onto the ½" hex of the gearmotor output shaft, ensuring that
iv. Open the test links on Battery Terminals 4 and 5 to remove power to the
2. Apply a 5/16" wrench to the brake end of the gearmotor to relieve pressure from the lock bar.
3. Remove the lock bar and use the 5/16" wrench to keep the gearmotor stationary.
4. Install the torque wrench onto the ½" hex of the gearmotor output shaft (Figure 4.4).
5. Gradually release pressure from the 5/16" wrench until full gate arm torque is held by the
torque wrench.
6. Hold the torque wrench stationary and ensure the gate arm is not bouncing. Read the torque
value indicated on the torque wrench.
7. Use the 5/16" wrench to hold the gearmotor stationary and release pressure on the torque
wrench.
8. Repeat Steps 5 – 7 a total of three times to obtain an accurate, average reading for the vertical
torque.
9. Install the lock bar onto the ½" hex of the gearmotor output shaft and engage the slot in the
lock bar with the reaction pin (Figure 4.4).
10. Use the 5/16" wrench to release drive train pressure until full gate arm torque is held by the
lock bar.
11. Compare the value from Step 8 to Table 4-2:
a. If the vertical torque measured is lower than indicated in the table, move the
counterweights closer to the mast.
b. If the vertical torque measured is higher than indicated in the table, move the
counterweights further from the mast.
c. If the vertical torque measured is within the range indicated in the table, tighten the
adjustment nuts on the counterweights.
12. To safely lower the gate arm:
a. Ensure the motor plug is connected to the main board.
b. With the main board still powered off, apply the 5/16" wrench to the gearmotor to keep
it stationary.
