The magnetic sensors are now offered by Maximum Controls as an option. Due to overwhelming request from our customers, all of our sliding gate operators are now shipped with programmable virtual limits as the standard and the sensor harness and chain magnets as an option. For new customers, the following bullet points explain how the magnetic limit sensors work.
• Hall Effect sensors identify precise rotational positions.
• DSP memory logs 30 samples per inch during every inch of gate travel and retains
limit positions in non-volatile RAM.
• The chain magnets are used to establish open and closed position during a learn
mode where the gate travels at half speed and the limits are stored.
• The limits are re-learned automatically after a complete power failure, AC and battery, on the first cycle after power restoration.

The magnetic sensor option can be ordered factory installed or can be retro-fitted onto any of our sliders in the field.

The Max Slide Gate Operator Series implements 3 various gear boxes depending on the model.

Max 1200 FS PRO: Size 50, 20 to 1, High
Efficiency, Heavy Duty Cast Iron Gearbox.

The Max 1200 FS PRO gate operator gearbox is highly efficient; producing maximum torque, maintaining a low amperage draw by reducing resistance, and providing super silent operation.

The rugged cast iron housing, bronze gears, and double sealed heat-treated solid shafts have been designed by a team with over 40 years of experience in the gearbox industry. High speed ball bearings and a synthetic oil bath keep the operator functioning flawlessly through extreme temperature ranges without need for belts, chains or pulleys—which are subject to wear—raising maintenance issues. We invite you to compare Maximum Controls’ gearboxes to any other gate operator manufacturers.

The brushless DC motor in the Max 1200 FS PRO Slide Gate Operator uses “Hall Effect” magnetic sensing to identify precise rotational positions during gate movement. That’s over 30 samples per inch of gate travel. Using this positional feedback, intelligent ramp-up and ramp-down of the gate speed is employed to minimize stress on all mechanical components.

Hall Effect Sensors are utilized to identify the position of the gate at any given moment, synchronizing the gates to open and close at the same speed. This technology is combined with a dynamic magnetic brake system which stops the gate instantly when colliding with an obstacle.

Our brushless DC motors can withstand and operate in extreme high temperatures up to 165F (+74C); this surpasses any other motor technology we know of in the market today. The Max brushless DC motor’s torque is equivalent to a 1 1/4 HP AC output torque motor and can operate approximately 35,000 hours, which is about 6 million cycles. This means the motor can last for decades to come. Maximum Controls stands behind our motors with a 5-year warranty.

Maximum Controls’ brushless DC motor control enables precision movement that traditional brushed motors can not replicate. For example, no overcoasting. This ability is crucial in bi-parting slide gates on the same track, as well as catch posts or columns that can’t be avoided.

Another advantage of precise gate control is the ability to stop instantly. In an emergency situation, this is critical. When a safety edge is struck, stopping on a dime to reduce risk of injury or damage to equipment is imperative. Our motor control technology is absolutely the most advanced on the market.

Max Slide Gate Operator’s power supply utilizes a 15 Amp torroid and power management board. The power supply is designed such that it is not overstressed under any extreme load or temperature conditions. The power supply input accepts 115 or 230 voltage via selection switch. During gate operation, the battery is not utilized while AC is present, thus preserving the life of the battery.

Input AC Power/Amps:
Switchable: 115VAC / 6 Amp, Single Phase or 230AVC / 2 Amp, Single Phase

The Max MAGIC BOX feature can save thousands of dollars in trenching and costly permit fees. Unforeseen complications like rock formations or utility lines that have to be trenched around can be avoided by using the Magic Box. This feature is a power management system that does not rely on battery power and as a result the battery life is not compromised.

Because the Magic Box does not rely on the batteries as a booster, the gate remains operational regardless of whether the batteries are malfunctioning or the batteries are removed. This technology is unique only to Maximum Controls.

One of the primary goals of the Max 1200 FS PRO is to provide the most secure, easiest to maintain gate operator with higher gate speed motion and advanced loop management.

Max 1200 FS PRO uses non-volatile memory to continuously log performance characteristics and input/ output events. A service technician can access this data via USB port to download the event history, quickly diagnosing complex or intermittent problems that traditionally have been very difficult to isolate and repair.

By plugging in a USB thumb drive into the USB port, all the diagnostic history will download, working as a “Black Box” to diagnose what occurred. The event history is stored as a .TXT document which can be emailed to the factory for, if necessary, on-site diagnosis. The .TXT file is a log of the most recent 8000 events reported by each module to the central logger.

Tamper Alert and Gate Disable

Maximum Controls’ patented Tamper Alert triggers a relay when an unauthorized entry attempt by chain-drop or gate movement has occurred. It’s simple, if someone cuts the chain the magnet falls off the sensor and the Tamper Alert relay activates. The relay command can trigger an audible alarm, a burglar alarm system or other devices with relay inputs such as a security cameras.

Unique to all Maximum Controls gate operators is the Gate Disable feature which disables normal open commands from devices like a keypad box or exit loop. Gate Disable prevents someone from breaking into a property by tampering with the inputs in a keypad box or triggering the exit loop with a piece of metal to open the gate. The Gate Disable feature is useful when a gated area needs to be secured from all BUT emergency vehicles and/or other authorized vehicles. When Gate Disable is turned ON it gives the occupants 3 minutes BEFORE arming, allowing enough time to leave the property. If there is an attempt to open the gate in an unauthorized manner, the gate will not open but will sound an alarm and trigger the Tamper Alert relay.

The Max Slide Gate Operator Series offers the most robust lightning protection available in the industry. The Max Slide Gate Operator Series protects all peripheral inputs, loop inputs, power inputs, relay outputs, and all communication lines (over 44 channels of protection) in 1/1,000,000,000 of a second. With special emphasis on power supply protection, the Max Slide Gate Operator Series is guaranteed to withstand any lighting hit more than 50 feet away. Truly protected like no other operator in the world.
