In order to be able to use these possibilities and to guarantee commu-
nication of your GT1 with the various participants in the network, e.g.
the diagnostic head, the OPPS or a network printer, it must be possible
to uniquely identify the devices in the network.

As expansions have meanwhile been introduced in several perfor-
mance levels for the use of the diagnosis and programming systems
DISPlus, GT1, SSS, OPPS/OPS and DH in a network, these functions
and services are summarized in a separate set of documentation.
Please read through this information provided on the documentation

Window

The graphic displays on the touch screen are referred to as

windows or also masks. They display all the information and

control functions.
Windows usually have the same structure: bars of buttons at the

top and bottom borders for control in the individual operating

modes; the middle (and largest) section is the workspace where

you can make selections or enter data. Smaller dialog boxes that

contain special messages or prompts can be superimposed on

the main window.

Title bar (1)

The title bar indicates which operating mode and in which win-

dow you are currently working.

Button (2)

In each window, different buttons appear, and you can use these

to select the various functions.
You can see from the color of the button whether it is enabled. If

it is dark and the screen surface appears concave (relief), it has

been pressed and/or enabled.

"Services"

button (3)

The "Services" bar contains a number of buttons which, when

pressed, each open up a pull-down menu containing other

buttons. On the right border of this line is the "Help" button (see

Section 4.7).

Switching Off

To terminate your work with the GT1, press the on/off switch.

Depending on how long the button is pressed, the GT1 is shut

down in one of two ways.

4.11.1 Shutting Down the System

Briefly (approx. 2 seconds) press the on/off switch until an

acoustic signal sounds. The shutdown procedure takes approx.

2 minutes and ends with the touch screen and LED 1 going out.

During this period, you can see an arrow pointing downwards

bearing the following text:
System is coming down.
Switching off the GT1 does not interrupt the battery charging

process. The LED "Battery" also lights up when the operating

unit is switched off, provided it is connected to an external power

supply. It goes out when the battery is fully charged.

Note
A window with the following message appears on the touch

screen: Confirm with OK of you want to switch off or Cancel if

not. This window disappears after a short period if you make no

entry.

Note

The information in the line with the battery indicator has changed as part of the
introduction of the network full functionality. Please read the documentation
"Full Network Functionality".

4.11.2 Forced Switch-off

If a fault occurs during operation, and this means that the oper-

ating modes can no longer be operated correctly, you can termi-

nate your work on the GT1 using the forced switch-off and then

restart.
To do so, press the on/off switch for longer than 5 seconds. The

current to the operating unit is cut off.

Caution
A forced switch-off is necessary after a new installation of the

Base CD in accordance with Section 2. Only use it in emergen-

cies when a proper shutdown is not possible, as otherwise there

could be a danger that the installed software becomes inconsis-

tent and has to be newly installed.

Note
In the case of forced switch-off as well, the prompt "Do you really

want to switch off the tester?" appears if the system can still out-

put this message despite the fault situation which has occurred.

Troubleshooting

The GT1 is a product of SIEMENS. It was inspected before it left the
factory. Carefully selected components and maintenance of numerous
quality controls guarantee high resistance of the GT1. Should a fault
occur in spite of this, please consult the instructions in this chapter be-
fore contacting the Customer Service responsible.
Faults that can occur on the GT1 can be divided into the following
groups:
•

Faults caused by environmental influences: ambient temperature,
(aggressive) moisture, dust, soot, grease, flying sparks, mains sup-
ply, transformers, large electric motors, radio-control systems, vi-
bration.

•

Faults on the GT1: control panel, docking station, diagnostic head,
cables and other accessories such as keyboard.

Please attempt to determine the fault and localize it as precisely as pos-
sible. Follow the suggested solutions provided and perform all the rec-
ommended measures if possible.

Note

If the fault which has occurred cannot be rectified with the measures
described, contact the SIEMENS Hotline by phone. The telephone
number of the Hotline responsible for you is contained in the documen-
tation "SERVICE ADDRESSES". In cases where practical, you can pre-
pare a Fault Report Fax. The fax number is also contained in the
documentation "SERVICE ADDRESSES".

Faults: Symptoms/Causes

5.1.1

Self-test

After switching on, the GT1 automatically runs a self-test. It is ready for
operation when the start window is displayed and operation via the
touch screen is possible.

Note

This self-test is not identical to the self-test that can be called up in the
"Administration" operating mode (see section 4.6).
If you receive error messages after this self-test, then send a Fault Re-
port Fax following clarification by phone with the SIEMENS Hotline.

Fault Codes

Faults can occur when you are working with the GT1, and these can
have a variety of causes. Most fault or error messages are supplement-
ed by a fault message text indicating possible incorrect operation.
Example: If the MFK 1 or the current clip are not connected when the
measurement system is switched on, measurement system faults are
displayed, e.g.:
Fault code 500.894 "Connect the measuring cable MFK1"
Fault code 500.871 "Connect the measuring cable current clip".
These fault codes are stored in so-called code volumes: the first three
positions indicate the type of fault; separated by a period, the last three
positions give a precise indication of the fault. In many cases, a plain
text describes the fault or how to remedy it.
