BL105

BARRIER LOGIC WITH
RS485 COMMUNICATIONS

 

The BL105 consists of a barrier logic with an integral RS485 communications port. The unit has been developed to control barriers using magnetic motors with ease of installation. The communications allows access to internal setup parameters such as timers, as well as counters for auditing purposes. The BL105 can be connected to the serial port of the Point Of Sale device directly, multi-dropped on the RS485 network with other logic units, or linked to a PC running software for configuration and monitoring of the parking system. A built in real time clock is used to time stamp alarms and non volatile memory is used to store counters from all inputs as well as all configuration parameters. The barrier can be remotely raised and lowered by sending commands over the network.

Standard features of the logic on the unit are :

Seperate Memory/Non Memory input.

The Memory input feature will allow opening inputs to be memorized. This will then enable a number of vehicles to pass over the closing loop before the barrier lower output is enabled. The purpose of this feature is to enable vehicles to pass the barrier without opening and closing for each vehicle and hence allowing rapid entry or exit of vehicles.

Two protection inputs (barrier door open and barrier arm removed).

Inputs are provided to give feedback to the PC/POS on the status of the door giving access to the inside of the barrier housing and also indicating if the barrier arm has been removed.

Automatic/Manual mode.

This mode allows the barrier to be manually operated for maintenance purposes.

Barrier raise/lower relay output.

This output is used to control the motor which raises or lowers the barrier.

Ticket vend interlock relay output.

This output is used to prevent tickets from being issued when the barrier is in the raised position.

Time out if vehicle reverses out.

On some occasions a vehicle may raise the barrier and then reverse out. In this situation the logic will time-out and automatically lower the barrier.

Roll-back protection.

After a vehicle has passed the closing loop and the barrier is closing, it is possible for the vehicle to roll backwards under the closing barrier. In this situation the logic will raise the barrier again until the vehicle moves forward off the closing loop.

Automatic closing from external loop detector input.

The loop detector is connected to the logic and is used to close the barrier when the vehicle has passed over the loop.

Facility for extra loop detector for opening input interlock.

Another loop detector may be used to prevent the barrier from being raised when there is no vehicle present. This is done by placing this loop in front of the barrier and a vehicle must be present on this loop to allow opening of the barrier.

Facility for Free Exit loop detector.

Another loop detector may be placed after the barrier and used to raise the barrier as a free exit option. This feature is normally used in a bi-directional lane.
