General Description

The A10 is a heavy duty sliding gate operator designed to open and close sliding gates.

In cases where chain, (as opposed to toothed rack) drive is required, an optional chain drive kit is

available.

The key to the A10's outstanding torque and duty cycle lies in the 3-phase induction motor and electronic

inverter that form the heart of the system. Single-phase 220-240VAC power is converted into variable

frequency 3-phase power, allowing electronically controlled soft starting and stopping of the motor.

An optional DC converter is available, containing back up batteries and UPS type backup circuits. This

enables the A10 to continue operating for a limited period in the event of a power failure.

In order to cater for high duty cycle installations, the A10 Endurance model is offered. This model utilizes a

continuously powered cooling fan, whilst the basic model utilizes the motor's standard shaft driven

cooling fan. The A10 heavyweight model is similar to the Endurance model with the exception of the 17

tooth output pinion. It is suitable for sites with a gate mass up to 2000kg

Gate travel limits are managed by an opto-electronic system, comprising a gate mounted origin marker

and an internal rotary encoder. This system yields precise and repeatable control over gate position.

Advanced features of the CP201 logic controller include:-

Automated setup of gate endpoints (limits).

Fail safe collision detection and auto reverse (adjustable sensitivity).

Smoothed start/stop (ramp up/down).

Multiple operational modes.

Selectable, adjustable autoclosing.

Pedestrian (partial) opening.

Positive Close Mode.

Safety input for sensitive edge/safety beam/inductive loop.

Advanced lightning/surge protection.

Timed courtesy light output.

Multiple preflashing modes.

SPRINT gate mode (high speed operation).

The A10 inverter and 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. In order to ensure that

the surge protection is effective, it is essential that the unit is properly earthed.
