Installation Instructions
Powering-Up the PDU

1.
Install the CD-ROM.

2.
Press the PDU power on switch (Fig 1-2). An
audible tone will be hears and the green PDU
power on indicator (Fig 1-6) will illuminate. The
touch sensitive screen will also be activated. If this
does not happen, see the problem solving section.
3. Adjust the contrast control (Fig
1
-4).

4.
When the PDU is switched on, it will perform an
automaticself-checktotesttheinternal components.
On successful completion of the self-check, a PDU
symbol will appear with a 'tick' next to it (Fig 10).
The PDU will then display the language selection
screen (Fig 11).
5. Select the required language and confirm the
selection (Fig 11).
Hole: PDU text is available in
English,
French,
Italian,
German and Japanese.
6. The PDU will then load its software from the CD-
ROM and display the 'main menu' (Fig 12).
7. New users may select 'Training' and press the 'tick'
icon to enter the on-screen PDU training
programme.

Installation Instructions
Step 16
Observe the display screen. Is the screen displaying
either of the symbols shown in Fig 19?
YES - Remove the CD caddy and check the CD-ROM.
Re-install the CD-ROM. Go to step 13.
NO - Co to step 19
Figure 19. Reload the CD and retry
Step 17
Connect the PDU to the base station top left connector using the second PDU to base station cable (0064) (Fig 34).
Is the screen displaying the symbol shown in Fig 15?
YES - Go to step 18
NO - The first PDU to base station cable is faulty, renew the cable (0064)
Step 18
Connect the PDU to the VIA using cable (0030) and connect the VIA to the VBA using cable (0028). Connect the
VBA to a charged battery. Does the VIA panel indicator flash for more than 5 seconds after pressing the 'tick'
icon.

YES - Renew the electronic module (0019)
NO - Renew the PDU (001 7)
Step 19
Observe the screen display. Is the screen displaying the
symbol shown in Fig 20?
YES - During the data transfer, the connection was lost.
Check to see if the cable connections are intact, if not,
reconnect and go back to step 13.
NO - Go to step 20
Figure 20. Data transfer connection lost
Step 20
Observe the screen display, is the language selection
screen displayed (Fig 21)?
YES - Try to select a language, go to step 21
NO-Call your local GenRad Service Centre for advice.

Users Guide
Parameter Name
Parameters can be fault codes, inputs to, or specific
outputs from, a vehicle control module.
The number of parameters selectable is limited to 32.
If the number of parameters available for customization
exceeds the d isplay
area,
the arrow buttons wi
11
be present,
allowing display area scrolling.
The parameters declared to Datalogger are initially
presented in alphabetical order.
Record Enabled
Record enabled is used to select which signals are to be

recorded.

To select a signal for recording, touch the rectangle next
to the signal name.
The record button will then be displayed.

Nofe:
Additional rectangles may appear in other columns
beside a selected signal name, indicating that the signal
units may be changed or that the signal may be used
as
a

trigger.

It should be noted that the more parameters you select to
record the slower the PDU's sample rate will be for each
parameter e.g. The PDU may be able to monitor six
parameters sampling each parameter twice a second. If
the number of parameters is increased to twelve then the
PDU would only be able to sample each parameter once
per second, thus reducing its ability to capture fast faults;
therefore it
is
recommended that the number of parameters
is kept to a minimum.
Display Order
Parameters may be displayed on the waveform/ bargraph
screen in any order.
To set the parameter display order, press the required
rectangle to create a numbered list.
Note: It
is
not
necessary to
display all of the parameters
required to be recorded.
This has particular benefits if a parameter is to be used as
a trigger but is not required to be displayed.
Trigger Action
For a detailed description of trigger action, refer to the
Trigger Customisation description on the following page.

S.I.
Units
Certain parameters can be measured / displayed in a
number of different units eg temperature in °C or °F. If a
rectangle appears around the displayed units in the
'S.I.'

column then the units are selectable. Each time the
rectangle is pressed, the selectable units scroll one step
through the available options.
Other Features
To make parameter customization easier two icons have
been introduced on to the bottom of the screen, these are:
This icon simply puts all ofthesignals selected for
recording in alphabetical order irrespective of
the language.
A B C
This icon will put all of the signals selected for
recording at the top of the parameter list in
numerical order.

^T/^

After the parameter customization process is completed,
return to the Datalogger main menu.
Default Customisation
To cancel all customisations, press the
Customisation Reset
icon.
This will reset the
customisation on all parameters to the default

setting.

Trigger Customisation
Datalogger operates using a 'rolling memory'.
When the Record icon is selected on the waveform
display, PDU will start to record data, it will then continue
to record data until its memory is
full.

At this point it will continue recording by overriding the
oldest
data.
This process will continue indefinitely or until
the trigger is activated.
When the trigger is activated it performs a number of
functions.
a) The first function istoplaceazerotimepointwithin
the stored data, this enables the trigger point to be
easily accessible in later stages.
b) The second function is to set a timer, ensuring that
the PDU wil
I
only continue recording for the time
selected in 'test-duration'.

Fault Overide
If fault overide is OFF, the trace recording will stop
when
a
fault
occurs.
With fault overide
set
to
ON,
trace
recording will continue after fault occurence
and
show
vehicle performance after the fault.
Language
Permits selection of one of the following languages:

selected.
If
you
accidentaly select
