Installation manual

2. Determine a suitable position for the pedestal or wall mount bracket using the swing angle and
dimensions A and B as found in the tables in Fig 7 to 11. (Values given in BOLD indicate the
recommended dimensions). Before finalising the position of the pedestal or wall bracket, see
points 5 & 6 below.
If it is not possible to find a suitable position within the given A and B dimensions, then contact your
local Centurion Systems sales office.
3. Determine the vertical height of the pedestal or wall bracket to be 37mm above the gate bracket as in
Fig. 12.
4. If installing a pedestal, prepare a square hole for the pedestal foundation according to Fig. 12 at the
predetermined position.
Mount Gate Bracket
5. Locate a suitable place for mounting the gate bracket according to dimension "C" as shown in Fig. 12
By positioning the gate bracket further from the hinge (increasing the "C" value), it would:
l
increase the time it takes to open the gate (make it slower),
l
improve the gates locking and security properties.
(The A dimension does not affect the opening time or other properties of the gate.)
6. Determine the height of the bracket above ground by taking into account drive arm clearance and
ground clearance for the padlock. (See Fig. 12). Once correctly located, weld or screw the gate
bracket to the gate using the two M4 screws provided.
Route Cables & Secure Motor Mounting
7. Route cables as determined in the cabling plan (Fig. 5), making sure that all cables protrude at least
400mm above the pedestal mounting plate or wall mount bracket as shown in Fig. 13.

8. Securely concrete the pedestal into position making sure that it is vertical, and at the correct
height relative to the gate bracket, as shown in Fig. 12. Allow concrete sufficient time to cure.
In the case of a wall mount installation, securely fix the wall mount bracket in the determined position
to the wall or pillar using four M12 Rawl bolts.
Fasten Gearbox in Position
9. Fasten the motor onto the pedestal adaptor plate or wall bracket, as shown in Fig. 14, using the M8
bolts and spring washers as supplied.
Determine Drive Arm Length
10. Depending on the particular installation type, determine the drive arm length as follows:
For Standard Pedestal & Outward Opening Gates:
Measure dimensions L (long) and S (short) as in Fig. 15 and calculate the drive arm length D as
shown in Fig. 15. DO NOT CUT THE DRIVE ARM TO THIS LENGTH. Cut the drive arm at least 50mm
longer than D. The cut length is therefore = D +50mm. (See Fig. 16)
For Pedestal Mounted Installations With Limited Space:
From the tables on Fig. 8, determine the drive arm length D, and select the boldface value if the motor
is mounted in the recommended. DO NOT CUT THE DRIVE ARM TO THIS LENGTH. Cut the drive
arm at least 50mm longer than D. The cut length is therefore = D + 50mm (see Fig. 16)
Assemble the drive arm and connecting arm as in steps 11 to 18 and check the gate operation
• If the drive arm interferes with the gate or,
• If the ball joint on the drive arm is more than 30mm from the obstructing wall, then,
Shorten the drive arm by 25mm and repeat the process until the gate operates smoothly.
