lating detection faults, it is important to have a manual count adjustment facility that can be used
from time to time whenever required� In the Dupline carpark count system this manual adjustment is
performed though the built-in web server, which can be accessed from a smart phone or a laptop� By
using a standard browser, the number of available spaces from each zone can be read and adjusted if
needed� The web server is also used for the configuration of the MZC�
The minimum requirements for this simple stand-alone system are:
- MZC module
- 2 power supplies
- 2 sensors to detect passing cars at the entrance
- 2 sensors to detect passing cars at the exit
- Configuration unit GP7380 0080
- PC to program the MZC
- Carpark monitor module GP3482 9091 724 programmed as “Master”
- 2 automatic fuses on each 2Amp DC to protect “pow out” on the L1 and L2 bus
- Displays (optional)
The power supplies used must be selected with the correct ampere size� Each of the Carpark Mas-
ter Channel Generators GP3290 0003 700 can supply the third wire with 3 Amp and the output of
the GP3290 0003 700 is pulsating� This means that the power supply must be minimum double size
(6Amp)� The power consumption depends on the number of sensors connected to the L1 bus and the
number of monitor modules connected to the L2 bus� We recommend to install a DC automatic fuse
on “pow out” for GP3290 0003 700� This is to avoid damaging the module if “pow out” by accident is
short-circuited to gnd� See diagram next page�
Note
: Do not short circuit “pow out” and D+ on the master module GP3290 0003 700� This will cause
an irreversible damage on the module� Be sure that wiring is correct prior to connecting power to the
system�
