Installation: Factory-Assembled MC-6000 Systems
INSTALLATION INSTRUCTIONS: PRE-ASSEMBLED DOUGLAS MC-6000 SYSTEMS
In most cases, a Douglas BACnet-accessible MC-6000 system
is assembled panel-by-panel and initially configured at
the factory.
For each panel in a pre-assembled system, it is necessary to
install the panel, check the basic network settings, connect
the switch inputs to the appropriate group inputs and connect
the outputs to the appropriate relays.
After this is done for all the panels in the network, the panels
are interconnected following the one-line diagram supplied
with the system. If not previously done at the factory,
outputs can be assigned to the group inputs of each relay
scanner once the panels are interconnected.
1. Install the pre-assembled relay panels. Be sure that the panels are
located closely enough together so that the network line length
required to interconnect them does not exceed the specification
called out in the
One-Line Diagram
page of the drawings supplied
with the system.
2. Make sure the Douglas network select setting and connnections
on the WNG-2133 BACnet Node are correct for a
MC-6000 System.
3. In each panel, connect the lighting loads to the output relays of
the output card. You should make note of which load is
connected to each relay in the relay schedule for each panel.
4. In each panel, connect the group switching devices (switch or
timer) to the input cards. If you are connecting 24V switching
devices other than a default Douglas switch or time clock, you will
have to first configure their inputs. Refer to the MC-6000
Programming Module Manual for details.
5. A maximum of 4 switching devices can be connected in parallel
to the same master input, with a maximum wire length of
2000'/600m if using 18 AWG wire.
6. Interconnect the MC-6210N-CPU cards with the data signal
wire. Be sure to connect them in the exact order shown in the
One-Line Diagram
in the drawings supplied with the system.
7. Power the system up. LEDs will flash briefly on the WNG-2133
device and then begin blinking to indicate OK status.
8. Determine which output relays are to be switched together as
groups. Different output relays from any panels in the network
can be grouped together to be switched by the same group
input or network device. An output relay can also be in more
than one group.
9. All programming and configuration of the system is implemented
via the RS-485 dataline through a front-end PC.
To configure the MC-6000 software:
1. Change the shortcut by adding
-w1
after the executable file
in the
Target
.
2. Open the software with the BT files for the project.
3. Go to:
Config/Remotes
.
4. Create remote number
252
, name
252 Gateway
5. 0 for all components.
6. Set all the address DIP switches to the down postion on the
MC-6210N device.
7. Go to:
Groups\Supergroups.
8. Create a supergroup
SNVTScene001
and add groups as
required.
9. Go to:
Misc\Online
.
10.
Click
Interface
, then select
252 Gateway
.
11. Download, plus download to all panels afterwards.
