ETAS
Configuration
You define whether the current measure signals are output as analog or digital
values via a jumper strip on the carrier board; further settings such as the thresh-
olds for the LED display etc. are made in the software (in LABCAR-RTC).
3.2
Connecting the Battery Voltage
The battery voltage is connected at the “Battery_IN” connector (see
"“Battery IN” Connector" on page 35). The correct cable (“CBAV300.1-2”) can
be obtained from ETAS (see "“CBAV300.1-2” Cable" on page 38).
The battery node status signals from the ES1391.1 Power Supply Controller
Board (and possibly back to the ES1392.2 High Current Switch Board) are con-
nected at the ES4408CON.1 Communication Interface. (For more details, refer to
the User’s Guide of the ES4408CON.1 Communication Interface).
3.3
The Backplane of the ES4408.1 Load Chassis
This section describes the backplane of the ES4408.1 Load Chassis.
The backplane (see Fig. 3-1) is intended for
• Five slots (3 U) for high current loads
of which
– 3 x 14 HP for injector loads (slot 0..2)
– 1 x 6 HP (slot 3) and 1 x 4 HP (slot 4) for loads with position feedback
(throttle valve, EGAS. etc)
• Seven 4 HP slots (3 U) for low current loads (slot 5...slot 11).
Fig. 3-1 shows the arrangement of the above-mentioned slots in the ES4408.1
Load Chassis.

High Current Connectors
The connectors for the high current loads (slot 0…slot 4) are of the type “DIN
41612 - Type F” and have three rows of 16 pins each (see Fig. 3-2 on page 23).
The permanent rating per pin/backplane channel is 7.5 A/90 V – the high current
signals specified with a maximum continuous current of 20 A are therefore
always routed via three pins/backplane channels.
Low Current Connectors
The connectors for the low current loads (slot 5…slot 11) are of the type “DIN
41612 - Type C x” and have five rows of 32 pins each (see Fig. 3-2 on page 23).
