One-Floor System Example
The diagram below is a theoretical example of how to implement 477 sensors on a single floor. Additional
floors would be configured, installed and brought online exactly the same way. Refer to section ‘Example of
a PGS for Multiple Floors’.
In the planning process, displays are positioned at the entrance and at each line.
The entrance display (A) will show all available spaces on the entire floor. The first branch display (B) will
show available spaces on that particular lane and the displays C and D will also show available spaces from
their lanes.
Design of the lanes can be made in many ways. We will always suggest an easy structure with a good
overview, which holds an extra margin for voltage drop, power consumption and any future installation.
In this example we have 6 lanes. Lanes 1, 2, 3, 4 and 5 each have two lines with 45 spaces per line, totalling
90 sensors per lane. Lane 6 has one line with 27 spaces.
The cable length has been calculated to 135 m (435 feet), so there is a margin for both voltage drop and
power consumption calculations.
Placement of the cabinets is in close proximity to the B, C and D displays providing us with the shortest
practical distance between the lanes.
Car Park Displays
The displays are all connected to the 3-wire Dupline® bus through the display-interface module that
converts Dupline® to Modbus. The displays can be connected to any of the lanes and show the demanded
available spaces. The programming of the displays takes place by using the SBP2WEB24 configuration tool.
Each of the displays requires its own power supply.
