1 Introduction
This User’s Guide describes the ES4434.1 Configurable Load Board.
It consists of the following chapters:
• Introduction
This chapter – here you will find general information on the ES4434.1
Configurable Load Board.
• "Hardware" on page 11
This chapter describes the features of the ES4434.1 Configurable Load
Board in more detail.
• "Technical Data" on page 19
This section contains the technical data of the ES4434.1 Configurable
Load Board.
CAUTION!
Some components of the ES4434.1 Configurable Load Board may
be damaged or even destroyed by static discharge. Leave the
board in its transport package until you want to install it.
The ES4434.1 Configurable Load Board should only be taken from
its package, configured and installed at a working place that is
protected against static discharge.
WARNING!
The components, connectors and conductors of the ES4434.1
Configurable Load Board may carry dangerous voltages. These
voltages may even exist if the ES4434.1 is not installed in the
ES4408.1 Load Chassis or the ES4408.1 Load Chassis is powered
off.
Make sure the ES4434.1 is protected against contact during
operation.

Introduction6
1.1 Features
The ES4434.1 Configurable Load Board is a 3 U plug-in board for the
ES4408.1 Load Chassis and is used to simulate low current loads in a LABCAR.
A total of seven boards of the type ES4434.1 Configurable Load Board or
ES4435.1 Current Source Load Board can be used in the ES4408.1 Load
Chassis.
The ES4434.1 Configurable Load Board has the following features:
• 24 configurable loads which are attached to the board with clips
• Assembled with 24 resistors of 510 Ω/3 W on delivery
• Each individual load can be configured to a specific battery node (via a
jumper)
• Battery nodes are activated via a relay (with the corresponding status
signal)
This makes the ES4434.1 Configurable Load Board suitable for projects in
which rare reconfigurations are necessary – for frequent changes, we would
recommend the ES4435.1 Current Source Load Board that has 24 current
sources configurable via software.

Introduction 9
1.2 Taking the Product Back and Recycling
The European Union has passed a directive called Waste Electrical and
Electronic Equipment, or WEEE for short, to ensure that systems are setup
throughout the EU for the collection, treating and recycling of electronic
waste.
This ensures that the devices are recycled in a resource-saving way representing
no danger to health or the environment.
Fig. 1-3 WEEE Symbol
The WEEE symbol on the product or its packaging shows that the product
must not be disposed of as residual garbage.
The user is obliged to collect the old devices separately and return them to the
WEEE take-back system for recycling.
The WEEE directive concerns all ETAS devices but not external cables or
batteries.
For more information on the ETAS GmbH Recycling Program, contact the ETAS
sales and service locations (see "ETAS Contact Addresses" on page 21).

in more detail.

Hardware12
Connecting the Loads
The loads are connected at connectors Load 9...Load 15 – the relationship
between the slot and the connector is described in the section "Assigning
“Load in Slot x” to Connector “Load n”" on page 16.
Backplane
The signals are routed from these connectors to the backplane and then on to
the relevant card slot (see "The Load Signals at the Backplane Connectors"
on page 17.)
Battery Node Relay
The battery node status signals applied at the ES4408CON.1 Communication
Interface (and also routed to the backplane) switch the relays for the battery
nodes against which the loads can be configured.
Pull-Up/Pull-Down Configuration
Jumpers are used to configure a load against a specific battery node (see
"Configuring Loads on Battery Nodes" on page 14).
Configuring Grounds
Use another jumper to select whether the AGND of the ES4434.1 is connected
to -UBatt or not (see "Configuring Grounds" on page 15).
LEDs
The LEDs on the front panel indicate the potential of the ECU connector (see
"LEDs" on page 15).

Hardware 13
2.2 Configuration
This section describes possible configurations of the ES4434.1 Configurable
Load Board.
These are:
• "Exchanging Load Resistors" on page 13
• "Configuring Loads on Battery Nodes" on page 14
• "Configuring Grounds" on page 15
Exchanging Load Resistors
The ES4434.1 Configurable Load Board is fully equipped with 24 510 Ω
resistors on delivery. They can be replaced at any time with other resistors –
please note that the maximum permissible power per load is 3 W.
To exchange resistors on the ES4434.1 Configurable Load Board, proceed as
follows:
• If the board is installed in the ES4408.1 Load
Chassis, switch off the power supply voltage
to the housing.
• Remove the screws with which the ES4434.1
is attached in the housing and pull out the
board.
• Remove the relevant resistors by pressing
down the white clips.
• Insert the new resistors.

Hardware14
Configuring Loads on Battery Nodes
Every load can be switched against one of the six battery nodes or -UBatt –
there are 24 jumpers “X1” to “X24” for loads 1 to 24 under the row of
resistors.
Fig. 2-2 Position of the Jumpers for the Battery Nodes and Possible
Configurations
You can see which jumper position configures to which battery nodes thanks
to the labeling next to the first jumper “X1” (on the right).

Hardware 15
Configuring Grounds
To avoid unwanted interferences to the supply voltages of the ES4408.1 Load
Chassis, the load side is isolated from the supply voltages via a DC/DC
converter.
The actual load reference potential is the output ground of the DC/DC
converter which can then be referred to battery ground -UBatt via jumper
“X29”.
Fig. 2-3 Position of Jumper X29
LEDs
There is an LED on the front panel of the ES4434.1 Configurable Load Board
for every load – it is addressed by comparators and always lights up when the
voltage at the ECU pin is greater than 6 V.
