Bench Mounting
The base station may also be mounted on a bench, which
must be in a safe position, stable and protected form
hazards and impacts. The base station must be mounted
at the back of the bench. 'Z' clips are provided for
permanent mounting. The bench surface must be kept free
from dust at all times.
CAUTION:
A gap under the base station must be
maintained free from obstructions to allow a flow of air
under the unit for cooling.
Electronic Module installation
WARNING: The base station electronic module must be
disconnected from the mains supply prior to installation/
removal from the base station assembly. DO NOT
reconnect to the mains supply until the module is safely
fitted into the base station. This unit must be earthed.
Note:
Users in North America are advised to replace the
ceramic mains fuse in the electronic module with theglass
fuse supplied.
Procedure
1.
Unlock the base station door
2.
Pull the right spring-loaded hinge (Fig 4-1) and
remove the door.
3. Removetheelectronicsmodulefrom the packaging
and place it on a firm surface.
4.
Remove the two screws and washers from the front
of the module (Fig 4-3).
5. Insert the mains power lead into the socket at the
rear of the module Fig 4-4), DO NOT CONNECT
TO THE MAINS SUPPLY.
6. Insert the two guide pins on the sides of the module
(Fig 4-5) into the base station slots.
7. Slide the module into the base station until fully
home,
raise the front so that it is level and draw it
slightly forward.
8. The two connectors on the front of the module will
appear through the matching holes in the base
station.
Support the module whilst refitting the two
retaining screws and washers (Fig 4-6).
9. Secure the mains lead to the underside of the base
station using the two cable ties provided (Fig 4-7).
10.
If bench mounting, the base station will need to be
turned on its back to install and secure the mains
lead.
11.
Refit the base station door.
CAUTION: Take care to avoid the sharp edges of the
module whilst installing. Take care to support the
module from the underside until the mounting
screws are secured.

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
charging the battery, loading software and storing
the PDU. Note that it is retained by raised retaining
blocks which fit inside the recesses under the
carrying cases (Fig 5).
7. Remove the protective coverfromthe PDU interface
panel socket (Fig
1
-7.6)
8. Usingthe PDU to base station cable (0064) connect
panel socket 6 to the base station left socket (Fig
1
-
19).
The indicator lamp will glow orange during
fast charge and yellow during trickle charging.
9. A second PDU can be fitted on the central position
on the base station and may be connected to the
right charging socket using a second cable (0064).
Note that both units may be charged simultaneously
but software may only be loaded from CD-ROM
using the left base station socket.
