General Description; Connections And Installation - Western WRD Manuel De L'utilisateur

General Description:

In WESTERN WRD SYSTEM, WRD is the coordinator and can work in two modes: Viewer or Controller.
:
Viewer
By setting in the setup menu 8.4 WRD -> Oper.Mode: 'MONITOR': you get the View mode.
In this mode, the WRD does not control the charging and discharging of the system, but takes care only of displaying the
parameters of the connected devices, can change the setup settings of the slaves, collects data and remotely displays
them in the cloud. The various devices autonomously perform their main functions independently from the WRD.
:
Controller
By setting in the setup menu 8.4 WRD -> Oper.Mode: 'CONTROLLER': you get the Controller mode
In this mode, the WRD adds a control over the devices, dynamically modifying some parameters in order to optimize the
energy management of the entire system and ensure compliance with the battery parameters.
The operating mode of the WRD in menu 2.0 can be recognized from the indication in the battery graphics (§ Main
screens).

Connections and installation

In the appendix (Pic. A1, An) the system connections are shown for the various possible configurations.
For its functioning the WRD uses the 12/24 / 48V system power supply and the connection WBUS which is physically an
RS485 bus, while the RJ45 Ethernet connection to the Internet cloud is optional.
The WESTERN WRD SYSTEM must be configured by setting to each WRMxx controller a unique address: from 1 to 32,
while the WBM already has a fixed address (33).
Installation procedure:
1) To install the WRD in a dry place, there are two fixing options: from the panel and with frame (Pic.4)
2) At the back you can access the electrical connections (Pic.4). Both the power connection and that of the WBUS are
a removable clamp type, easy to wire. Connect the cables correctly, if the power supply comes from the battery, it is
recommended that it is under the use of a fuse (0.5A) for cable protection. Finally, if it is used, also connect the
Ethernet cable.
3) Once all the connections have been made, power up the system. The WRD turns on and starts to function.
4) Now run the system configuration settings that will be required.
• At the menu: 8.0 WBUS CONFIG. you can use the 'AutoConf.' command for simplicity, or you can make address
settings manually.
• At the menu: 7.1 DATE / TIME you set the clock and time zone (Timezone).
• At the menu: 7.0 SYSTEM you make system settings. The correct profile must be selected, corresponding to the
battery features (an incorrect choice could lead over time to damage the battery itself).
5) Check the entire functioning by scrolling the screens.

It is recognizable if a WRM30+ is remotely controlled (by WRD) if, on the WRM30+ display, the battery contour flashes every ~3sec.
2
The WBUS has the RS485 as its physical bus, so the two poles A and B must be connected correctly, while the GND pole should be left disconnected.
