Revision 2
Power is fed into unit through circuit breaker CB1 in Figure 2 below. A common Live
bus is fed through RCBO 1, 2, 3 and 4. The neutrals are monitored by the power
monitoring circuitry on PCB000378 (WEX300-MTR) through shunts PM1, PM2, PM3
and PM4 on the neutral lines of the RCBOs.

7 System Description
7.1 Digital Inputs, Outputs and LEDs
The WEX300 has 20 digital inputs which can be setup in the configuration on
the WDC 100\200 NX. These inputs are 3.5mm stereo jack plugs to connect
to push buttons, optional remote controls and lighting switches and are
located on the bottom of the WEX300 housing. Below is a layout of the
connections on the bottom of the WEX300 unit.
Figure 4 Input Connections
From Figure 4 above SKT1 denotes Jack 1 and the numbering follows this
down to SKT20 which denotes Jack 20 in the configuration software. The Tip
of the 3.5mm jack is reserved for these input signals and the screen is
grounded. The Ring of the jack is reserved for the LED\Digital outputs and
are denoted as “LED” in the Configuration software, these are for input status
feedback. The behaviour of the LEDs is displayed below in Table 1.

7.2 Relay Outputs
The WEX300 has relay outputs which are used to switch the Socket and
Lighting circuits. The relay board is divided into two sections often referred to
as Room1 and Room2 or Cell 1 and Cell 2. Each room is allocated two relays
for sockets and four relays for lights this is displayed below in Figure 5.
Neutral to all circuits is common and the Live is switched.
Figure 5 Relay Outputs Sections
7.3 Communications
The WEX300 is a slave device and is controlled by a WDC100\200 via CANbus.
The CAN is connected via a 4way RJ11 connector. Within the WEX300 there are
three boards which also need to communicate, the control board, the metering
board, and the relay board, this is done via RS-232. The three boards are
connected via IDC connectors and ribbon cable.

Revision 2
7.4 Mains Voltage Devices
The WEX300 is a mains connected device and therefore caution must be taken
when wiring. Below in FIGURE is the section of the relay board which is Live,
elsewhere below the indicated zone is a maximum voltage of 12V DC.
Figure 6 Live Area of Relay Board
Majority of the Metering board is Live and is covered by a transparent plate to avoid
contact. Take care to isolate the devices correctly when connections are being
made.
8 Data Logging
Data logging records the events of all functionality. The data logs are stored locally
on the WDC 200-NX and can be exported to a PC or laptop. The download data is in
the form of a csv file and can be viewed via WDCMS or exported to an external
database.

10 Operation
Use the main isolation switch provided by the installer to switch the unit on or off.
The main isolation switch is located near to the electronic control box. If unit is faulty,
switch off the control unit until the fault is repaired by a qualified engineer.
WARNING! Risk of electric shock, serious injury and death. Only trained and
qualified personnel should remove the cover of the electronic control box.
11 Maintenance
We offer a comprehensive service package, details of which can be obtained from
our customer service department. A spare parts service is also available.
The electronic control unit does not have any user serviceable parts. In the event of
a fault, switch off the electrical supply and contact an authorised electrician to
replace the unit.
Any service or repair work must be carried out by a qualified engineer. During the
warranty period, the service or repair must only be done by a qualified engineer or
appointed service agent.
