KEY FEATURES

STANDARD APPLICATION

Recommended for most commercial door types including rolling slatted/grille steel doors, rolling sheet doors, sectional doors (standard lift, high lift, vertical lift) and bi-fold doors

SINGLE OPERATOR SKU

The DAVE operator simplifies inventory with a single operator SKU. It seamlessly integrates with a modular power cartridge that will suite the sites available mains power.

MODULAR POWER CARTRIDGE

The modular power cartridges can be swapped and can provide 1000W of power to drive the operator drive assembly.

WIRELESS/WIRED WALL CONSOLE

All programming, setup and editing are done from the floor level wall controller using the LCD screen and panel buttons. Added security with removable key switch for disabling access to menus.

POWERFUL DRIVE MOTOR

The use of a Permanent Magnet Synchronous Motors (PMSM) offers exceptional features and advantages. The key benefits and characteristics are high efficiency, high power density, high power factor, excellent torque characteristics (high torque at low speeds, smooth torque production, high overload capacity, good dynamic performance, low maintenance, high reliability, low heat generation, quiet operation, and precise control.

OPERATOR DRIVE BRAKING SUITE WITH ENERGY HARVESTING

The use of new “braking” technologies delivers on more precise door behaviors control:

•Regenerative Braking: When the main controller senses a closing door "free-falling," the motor generates kinetic energy. The operator intelligently harvests and converts this kinetic energy into electrical energy, using it to apply precise braking. This ensures smooth, controlled door travel and prevents "doors from racing."

•Zero Vector Braking: This system provides precise stopping by employing a Zero Vector brake that acts on the motor's stator windings via the motor driver. It guarantees the motor and door stop instantly and exactly at the commanded end position.

AUTOMATIC TECHNOLOGY TOOLBOX

A Smartphone APP tool can be used to connect wirelessly via Bluetooth to the wall console/operator for OTA (over the air) upgrades and diagnostics.

OPERATOR SPEED CONTROL

The DAVE operator allows you to adjust the open and close travel speed directly from the wall console menu, ranging from 2.5” to 18” per second This wide, adjustable speed range significantly reduces the need to match door and operator sprockets, as the motor delivers consistent torque regardless of the selected speed.

DOOR TYPE SELECTOR

The door type can be selected in the Wall Controller Console Menu, and the operator will load the default opening and closing travel speeds which can be adjusted to suit your speed requirements.

DUTY CYCLE

The Operator duty cycle depends on the door type and door curtain weight; the door needs to be well balanced. Duty cycle is 60% for well balanced 1200lb sectional or rolling steel door.

LIMITS SETTING

The operator uses an Electronic 12 Bit magnetic absolute position encoder to control the door travel limits, with the door travel limits set electronically using the LCD menus and control buttons in the wall console

MANUAL OPERATION - CHAIN HOIST

The manual chain hoist automatically engages with the operator drive mechanism when the hauling chain is pulled. The manual chain hoist has an electromechanical safety interlock switch which will disable the operator from working during manual operation.

SAFETY DEVICES - PRIMARY ENTRAPMENT PROTECTION DEVICES

There are several types of safety devices we offer which are listed below. Up to five safety beams can be installed – two by wireless and three wired.

DOOR BOTTOM RAIL EDGE SENSOR

The main control board has input terminals for the wiring of bottom rail edge sensors.

EXPANSION BOARD (OPTIONAL)

The expansion board is an optional accessory that has four programmable relays with dry contacts to drive external accessories like traffic lights, flashing lights, sirens, docking stations, etc. Each relay has a common, normally open and normally closed terminals and are programmable via the Wall Console Menu. An external power supply of 24V is required to drive the accessories.

UNINTERRUPTED POWER SUPPLY (UPS)

The operators with a single-phase power cartridge can be powered from a UPS.
