The following operating manuals are available when using the IRDH575 in
combination with EDS systems for other applications:
 
Manual for EDS470 application:
power supply systems, extended systems, systems with frequency con-
verters, response sensitivity of at least 5 mA
 
Manual for EDS473 application:
control systems, small systems, systems with PLC, response sensitivity
at least 0.5 mA
 
Manual about project planning for EDS470 and EDS473 systems
 
Manual for EDS460 /EDS490, Application:
power supply systems, extended systems, systems with frequency con-
verters, response sensitivity of at least 2 mA
for EDS461 /EDS491, Application:
control systems, small systems, systems with PLC, response sensitivity
at least 0.2 mA
7.3.5 Commissioning of an RS-485 network with BMS protocol
 
Connect the terminals A and B of all bus nodes in one line
 
Switch the terminating resistors on at the beginning and end of the
RS-485 network or in case of devices without a terminating switch, at
the end of the bus, connect a 120 Ω resistor to the terminals A and B.
 
Switch the supply voltage
U
S
on.
 
Determine one IRDH575 as the Master and assign address 1.
 
Assign the addresses (2…150) successively without gaps to all other
IRDH575 devices and other bus nodes (see table below).
 
Check whether a flashing point appears on all devices with a display
(BMS commands are being received). Other devices use an RS-485 LED
to signal the bus traffic.
 
The sub menu "ISO-Monitor" in the COM SETUP menu allows insulation
values of the ISOMETER®s to be queried. Before starting the query, the
address of the ISOMETER® has to be entered.
 
In the "EDS Test“ menu all preset Slave addresses can be checked
