2. General description
The D5-Evo is a domestic and light-industrial operator designed to open and close sliding
gates weighing up to 500kg. A custom designed gearbox moulded from robust
engineering polymers, coupled to a powerful 12V DC motor, provides fast and reliable
automation for entrances to homes and small housing estates.
The system operates off a 12V battery housed inside the operator using a switch mode
charger to maintain the battery in a fully charged state. The battery provides critical
power failure protection. A solar supply can be used as an alternative energy source to
charge the battery.
Gate travel limits are managed by an opto-electronic system, comprising a gate mounted
origin magnet and an internal rotary encoder. This system yields precise and repeatable
control over gate position.
Advanced features of the D5-Evo logic controller include:
Interactive graphical user interface via a backlit LCD display
Automated setup of gate endpoints (limits)
Fail-safe collision detection and auto reverse (adjustable sensitivity)
Smooth, adjustable start/stop (ramp up/ramp down)
Multiple operational modes
Selectable, adjustable autoclosing
Pedestrian (partial) opening
Positive close mode
Independent safety inputs for opening and closing beams
Automatic beam test for both open and closing beams
Advanced beam alarm functions
Advanced lightning/surge protection
Timed courtesy light output
Multiple pre-flashing modes
Independently adjustable motor speed in both opening and closing directions
Onboard CENTSYS code-hopping radio receiver with full channel mapping capability
(limited to 500 buttons)
Onboard ChronoGuard timer (patent pending) for autoactivation of various physical
input and outputs and time-barring of the same inputs and output including remote
controls
Lightning Protection
The electronic controller utilizes the same proven surge protection philosophy that is
used in all CENTSYS products. While this does not guarantee that the unit will not be
damaged in the event of a lightning strike or power surge, it greatly reduces the
likelihood of such damage occurring. The earth return for the surge protection is provided
via the mains power supply earth and/or earth spike located next to the operator.
In order to ensure that the surge protection is effective, it is essential that the
unit is properly earthed.
Theft Protection
While care has been taken in the design of the D5-Evo to prevent unauthorized removal
(theft) of the unit, an optional steel theft-resistant cage is also available for added peace
of mind.
