The Boards for the ES4408.1 Load Chassis
This section contains an overview of the boards which can be used in the
ES4408.1 Load Chassis for controlling and load simulation.
3.1.1
ES4408CON.1 Communication Interface
The ES4408CON.1 Communication Interface is used in the ES4408.1 Load Chas-
sis to communicate with the boards in the chassis.
Features
Via the 100-MBit Ethernet interface, the ES4408.1 Load Chassis can be inte-
grated into the HIL system with the LABCAR-OPERATOR software, the simulation
target with LABCAR-RTPC and the relevant hardware. The Ethernet interface can
also be used to control a standalone ES4408.1 Load Chassis with SCPI com-
mands.
The status signals of the battery nodes can be supplied (from the ES1391.1
Power Supply Controller Board) and led through again (to the ES1392.2 High
Current Switch Board) at the ES4408CON.1 Communication Interface. These sig-
nals are routed to the backplane of the ES4408.1 Load Chassis and used there
for the ES4434.1 Configurable Load Board to switch battery nodes or on the
ES4435.1 Current Source Load Board to activate current sources.
Place of Installation and Connections
The slot for the ES4408CON.1 Communication Interface is on the rear of the
housing, on the left (see Fig. 3-1 on page 22).
The Ethernet cable and the cables for the status signals of the battery nodes must
be connected.
Configuration
The configuration is taken care of in the software (in LABCAR-RTC) and primarily
concerns communication settings such as the Ethernet address, the Ethernet
adapter used on the Real-Time PC etc.
3.1.2
ES4434.1 Configurable Load Board
The ES4434.1 Configurable Load Board is used to simulate low current loads in
the ES4408.1 Load Chassis. It is equipped with 24 configurable loads: Each one
can be configured to a specific battery node.
A total of seven boards of the type ES4434.1 Configurable Load Board or
ES4435.1 Current Source Load Board can be used in an ES4408.1 Load Chassis.
Place of Installation and Connections
The ES4434.1 Configurable Load Boards are installed (mixed with ES4435.1 Cur-
rent Source Load Boards – see section 3.1.3 on page 21) in slot 5 - slot 11 of the
ES4408.1 Load Chassis (see "The Slots of the ES4408.1 Load Chassis (View from
the Front)" on page 22).
The channels of the boards can be accessed at connectors “Load 9” ...
“Load 15” on the rear of the ES4408.1 Load Chassis.
