This chapter describes the individual function units of the ES4456.2 Load Board
for 8 RB CRI3-x Piezo Injectors in more detail.
These are:
• "Connecting Loads and Measuring the Signals" on page 19
• "Overcurrent Protection of the Measure Outputs" on page 19
• "LED Display" on page 19
• "Acoustic Signals" on page 20
• "Calibration" on page 20
• "Settings in LABCAR-RTC" on page 20
2.1 Connecting Loads and Measuring the Signals
The ES4456.2 Load Board for 8 RB CRI3-x Piezo Injectors can be used in slot 1, 2
or 3 in an ES4408.1 Load Chassis. The loads are connected at the front panel
connector “Load 0...7” of the ES4456.2 - the measure signals are available at
connectors on the back of the ES4408.1 Load Chassis.
For details of the pin assignment of the front panel connector “Load 0...7” refer
to section "“Load 0..7” Connector" on page 23 – the pin assignment of the
measure connectors is described in the ES4408.1 Load Chassis manual.
Special cables are available for connecting loads and measure signals with a PT-
LABCAR (see "“CBAV344.1-1” Cable" on page 24 and "“CBAV345.1-1”
Cable" on page 25).
2.2 Overcurrent Protection of the Measure Outputs
The outputs of the ES4456.2 Load Board for 8 RB CRI3-x Piezo Injectors are pro-
tected against shorts to +UBatt and against ±60 V.
2.3 LED Display
The LED display on the front panel (see "LEDs for Status Display" on page 27)
shows when a specific voltage value between 0 and 250 V has been reached – if
the voltage at 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 20.
