UNIT OVERVIEW
The LiftMaster model MEGA SLIDE UL slide gate operator is
unique in the industry. Setting the MEGA SLIDE UL apart are
many features that make it the front runner in its class. With
standard features like:
•
Built in battery run - inherent 24 VDC backup power with
regulated 24 VDC for accessories.
•
High torque 1/2 HP 24 volt Permanent Magnet DC motor.
•
Full service controller with eight inputs and LED indicators for
loops, card reader, radio, etc.
•
Continuous duty operation for most types of gates.
•
Reversible gate direction for right or left handed operation.
•
Instant Reverse Device
(IRD)
monitor senses obstructions
going open and close.
•
Automatic open of gate when power is lost if desired (with 15
second delay selection).
•
ANTI-TAIL GATE with QUICK CLOSE feature STOP gate in close
travel if tail-gating is sensed
•
Upon complete system failure (lightning, surges, etc.) gate can
be pushed open by hand.
•
All rust proof aluminum construction with baked on powder
coat enamel.
•
Molded Polyethylene UV stabilized cover never needs wax or paint.
•
Direct drive gear reducer eliminates many parts that might
otherwise fail.
• Microprocessor
(RISC) based electronics with watch dog reset
timer.
•
State of the art MOSFET motor drive technology, NO contactors
or relays.
•
Dynamic motor braking to preserve gate stopping points.
•
Soft start and stop in open and close travel motions.
•

PRE-INSTALLATION NOTES
NOTE:
Before attempting any part of the installation, you must
read the entire instruction manual first and agree to the
stipulations stated on the warranty page.
Proper design:
Is important in your system layout and
installation. Safety devices must be used at all available points
where injury or property damage may occur. For protection from
injury to persons, use photo electric eyes on both sides of gate
and pressure sensing edges at all pinch points and at the front
leading edge of the gate. Safety loops (vehicle detectors) should
be installed in front of and behind the gate to provide a reverse
signal or stop signal to the gate operator. On cantilever gates, all
wheels should be enclosed so that fingers cannot reach pinch
points between the gate and wheels. All safety devices should be
tested and inspected weekly. If a safety device is not operating
correctly, the unit should be disabled until repair can be made by
a properly trained/experienced service company.
As the system designer/installer, you must advise your
customer/end user on the correct usage of the gate operator and
the system. In providing the service of design/installation of the
operator and system, you are responsible for proper training of
the customer as well as for the proper SAFE OPERATION. All
precautions to eliminate ALL hazards MUST be taken before the
unit can be put into operation. You MUST advise and warn your
customer of any hazards that remain or if they choose to not use
any of the recommended safety devices in the installation.
You are strongly advised to get in writing from you customer
their acceptance of your system and acceptance of any hazards
that remain.
SAFETY TIPS:
1)
Install the warning signs provided so that they are CLEARLY
VISIBLE any one in the area of the gate. (should your customer
reject the usage of warning signs, you will need to have them
sign a disclaimer).
2)
Install any and all devices that will open or close the gate so
that the entire gate and operator will be in full view by the
person operating the gate.
3)
DO NOT ALLOW any control device to be located so that a
person can access them by reaching through the gate pickets.
Devices must be at least 10' from gate and gate operator.
4)
Installing a pressure sensing edge (safety edge) at front of
gate to reduce the possibility of entrapment (use J5 terminal
#5 and common).
UL-325 56.8.4 (B, D, C, D, F).
Only install this operator on gates
used for vehicles. Pedestrians must be supplied with separate access
opening. Install in a location so that enough clearance is supplied
between the gate and adjacent structures so that when opening and
closing to reduce the risk of entrapment. Gate must be properly
installed and work freely in both directions prior to the installation of
the gate operator. Do not turn down (IRD) primary entrapment current
sensor to compensate for a damaged gate. Controls must be far
enough from the gate so the user is prevented from coming in contact
with the gate while operating the controls. Controls used to reset an
operator after 2 sequential activations of the entrapment protection
device or devices must be located in the line-of-sight of the gate.
CAUTION:
For use on a gate with a max. weight of 1000 lbs. and a
max. length of 30'. No binding is allowed, gate must be free moving in
both directions. It is highly recommended that high quality wheels
with sealed bearings be used for all applications.
