Powering-Up the Base Station
When first operating the System or when first using
a PDU fitted with substitute batteries, it will take up
to36 hourstoachievefull charge. Inthemeantime,
the PDU can be used whilst connected to the base
station or to the vehicle battery.
Vi/\RNmGS:
When using the system equipment, basic safety
precautions should always be followed, including:
Carefully read and follow all instructions.
Care should be taken as burns can occur from
touching hot parts.
Do not operate the appliance with a damaged
mains lead or if the appliance has been dropped or
damaged. Call your local GenRad Service Centre
immediately for a substitute
part.

Do not let the mains lead hang over the
edge
of the
table, bench or counter or come into contact with
hot manifolds or moving fan blades.
The Aston Martin Portable Diagnostic Unit
is
fitted with an
auto switching power supply suitable for voltage supplies
of 100 - 240 VAC 50 - 60 Hz. You need only check that
the power cord connector is of the correct type for your
power outlets.

1.
Connect the mains lead to the mains outlet.

2.
Check that the green indicator lamp above the base
station door is illuminated. If the green lamp does
not come on, see the problem solving section for
advice.
3. After a few seconds, during which the electronics
module completes its self-test, the red OK indicator
lamp should illuminate. If the red lamp does not
come on, see the problem solving section for
advice.

4.
Allow the base station electronics module to reach
working temperature. This will take approximately
BOminutes, after which time the base station will be
ready to accept the software on CD-ROM.
5. Slide the PDU into its carrying case and place the
associated cables and probes in the carrying case
compartments.
6. Place the carrying case onto the base station at the
far left side (Fig 5). This is the normal place for

Battery Charging
The PDU is fitted with internal NICAD batteries
which allow the PDU to be transported whilst
retaining programs. The batteries are not designed
to be used as a general power source. A special
circuit monitorstheamountofcharge in the batteries
so that they cannot be overcharged.
From the time when first operating the system or a
PDU fitted with substitute batteries, it will take up
to 36 hours to achieve full charge. In the meantime,
the PDU can be used whilst connected to the base
station or to the vehicle battery. Keep transit times
to and from the vehicle as short as reasonably
possible to preserve battery charge.
Subsequent battery charges
shou Id
take six to seven
hours from fully discharged. The PDU must always
be left connected to the base station when not in
use in order to keep the batteries fully charged.
CAUTION: The rechargeable NICAD batteries
fitted to the PDU are of a special type and must
only be replaced with GenRad approved parts. Do
not substitute the batteries with any other type.
Always
dispose
of old batteries in compliance with
local recycling regulations. The procedure for
changing the battery pack
is
described later in this
installation guide.

may also be made using the module pin selection function on the Teves Mk
II
braking system and on the Air Conditioning

system.

Training
An on-screen programme is provided to train new users in the use of screen icons and in the use of the digital multi­
meter and datalogger functions.
User Self Test
In order to prove that the equpment is functioning correctly, a complete user self test is incorporated. The user is directed
to test the PDU and then to progressively connect each part of the PDU system which will be tested by the software.
Any fault identified during the test is notified to the user. If no faults are identified, the user is advised on the correct
functioning of the system.
PDU Power
Power for the PDU is supplied via an internal rechargeable battery pack which can keep the PDU operational for
approximately one hour when disconnected from the base station and the vehicle. In order to preserve PDU battery
charge, power to the screen backlight is automatically cut after five minutes of inactivity. The power ON indicator
remains lit, indicating that the PDU is in 'stand-by' mode. One touch of the screen will restore backlight power.
When connected to the base station, power is supplied to the PDU from the Electronic Module to recharge the PDU
battery pack as necessary.
On 95 MY vehicles, the Vehicle Battery Adaptor (VBA) is used to maintain PDU power.
On 97 MY vehicles, when connected via the MPA to either diagnostic socket on the vehicle, power is supplied via pin
4 (chassis ground) and pin 16 (battery power) to maintain PDU power at all times even when the vehicle ignition is
switched off.
On all model years, when connected to the air conditioning system using the VIA, the vehicle battery adaptor (VBA)
must also be used to maintain PDU power.
