INSTALLATION AND SOLVING OPERATIONAL PROBLEMS
MASTER AND SLAVE SETTING
The selection if the unit is the Master or the Slave is done by the first switch on the DIP switch on the motherboard. The
DIP switch can be accessed after the upper cover of the terminal block is removed. This setting should be done only by a
trained installation technician.
Address setting
The setting of the address makes sense only with the Slave unit. The setting is done by the last 4 switches on the DIP
switch. In case the node is switched to the Slave mode, the setting console does not work.
Example:
Master, setting console:
01 00 00
Slave, communication, address 0: 10 00 00
DIN rail installation
The unit is mounted vertically onto the DIN rail in the switchboard. The device can be installed within the array of
modular devices on the DIN rail like breakers and contactors. It is advisable to install the Master unit right next to the
HomeGuard module and connect both units with a communication cable. The cables with a suitable cross-section are
connected according to the diagram in the chapter “
Connection diagram and LED indication
”.
Connection of RS485 line with HomeGuard (Master) and PortGuard (Slave)
The ShiftGuard communication modules in the
VoltGuard
system are used for transmitting information on residual
capacity, or for transmitting the status signals, typically information on the tariff. The connection is done through the
RS485 line. The line is connected using a usual twisted pair; a suitable cable is, for example, Lam Flexo Twin communi-
cation cable or Lam Flexo FTP. With a cable length of hundreds of meters, it is advisable to consider terminating the bus
by a termination resistor, usually up to 1000 ohms. However, it is not necessary in most cases as the bus communica-
tion speed is very low.
Switching on and checking LED status indication
Switching on the device does not require any special procedure. It is enough to connect the device to the power supply.
Once the device is switched on, it is advisory to check the LED status indication, see the chapter “
Connection diagram
and LED indication
”. In case the device does not work, check if PLC_IN and PLC_OUT are on the same phase. The con-
nection to a different phase may work thanks to inductive coupling between the supply conductors. However, such a
connection is unreliable. In case you cannot connect both nodes to the same phase, use the interfacial couplers (con-
tact the manufacturer) to establish the communication connection between the particular phases.
