(each with two channels) for simulating high-current loads (to 90 V and to
20 A), such as injection loads.
In the ES4408.1 Load Chassis there are three 14 HP slots for accommodating
ES4455.1 Load Boards or pre-assembled variants (see "“Pre-Assembled
Solutions” with Integrated Load Modules" on page 8).
When fully assembled, the injection loads of a 12-cylinder engine can be
simulated.
1.2 Features
The ES4455.1 Load Board has the following features:
• 3 U plug-in board (14 HP, 3400 mm x 100 mm)
• Four channels for load simulations to 20 A
• Four galvanically isolated analog or digital channels for current
measuring
• Four galvanically isolated analog channels for voltage measuring
• To date, modules for the Bosch Common Rail System (two modules
each with two loads) and Bosch GDI (two modules each with two
loads) are available

Introduction 9
1.4 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 25).

2.2 Current Transducers
The load current is measured in galvanic isolation by the current transducers.
Internally, the entire current range is mapped to a voltage range of 0..10 V.
2.2.1 Configuring the Current Transducers
The range of currents to be measured is configured using solder straps (on the
solder side of the ES4455.1 Load Board) at the current transducers (see Fig. 2-1
on page 11).
Fig. 2-2 Current Transducer Pins seen from the Solder Side (Front Panel,
Right)
Note
Use only the two inner rows for the solder straps as the voltage converter is
soldered to the outer ones.
Note
Please note that changing the current ranges makes recalibration necessary
(see "Calibration" on page 15)!

2.2.2 Calibration
ETAS provides a calibration service for correcting any current converter and
threshold offsets for the front panel LEDs.
The order data is as follows:
2.2.3 Overcurrent Protection of the Measure Outputs
The outputs (Ianalog, Idigital and Uanalog) of theES4455.1 Load Board are
protected against shorts to +UBatt and against ±60 V.
2.3 Digital Current Signals
The current signal over a load can also be output digitally – the upper and
lower thresholds are set via the potentiometers “Threshold high Load_n” and
“Threshold low Load_n”.
Once the upper threshold has been reached, the digital signal assumes the
value “High” and retains this until the lower threshold is crossed.
The settable ranges are:
• 0...2.5 V for the lower threshold in accordance with 0 A...Imax
• 0...2.5 V for the upper threshold in accordance with 0 A...Imax
Fig. 2-3 Digitizing an Injection Signal
The thresholds set are verified at the front-facing connector (see "“Threshold
Calibration Connection” Connector" on page 19).

2.3.1 Configuring Current Measuring
Current measuring (for all loads installed on the carrier board) is configured
using the “JP200” jumper strip.
Fig. 2-1 on page 11 shows the position of the jumper strip on the board – this
is only accessible when the rear load is removed.
The possible settings are shown in Fig. 2-4 on page 16.
Fig. 2-4 Current Measuring Configurations: Digital (Top) and Analog
(Bottom)
The configuration can also be queried in LABCAR-RTC. Select the ES4455-
Load-Carrier Device there, and then the “Data” tab. When an experiment is
running, the “JumperSetting” signal contains the configuration: 0 = digital,
1 = analog.
2.3.2 LED Display
The LED display on the front panel (see "LEDs for Status Display" on page 20)
shows when a specific current value has been reached – if the current over a
load is over this value, the relevant LED lights up.
The thresholds are set in the software; this is described in the section "To set
thresholds for LEDs" on page 17.
2.3.3 Acoustic Signals
An acoustic signal can be emitted when the above-mentioned thresholds have
been attained. The section "To set the beeper" on page 17 describes how to
enable/disable this function.
