1. INTRODUCTION
1 INTRODUCTION
The safety of all personnel who come into contact with the tester essentially
depends on an adequate understanding of the device. For this reason:
Prior to the rst putting into operation read these operating
instruction!
Note on operating instructions!!
These operating instructions apply to devices with and without the
touchscreen display. The menus shown can be useful for illustrating
the functions on devices without a display and therefore contribute
to an improved understanding of the device.
1.1 GENERAL INFORMATION
These operating instructions will make it easier to become familiar with
tester and its possible uses prior to placing in operation, and to use it
correctly. They contain information that will ensure functionally correct,
cost-effective and safe operation and they must always be available in
the place where the device is used.
The operating instructions are not only an indispensable aid for new trainee
operators, they also contain useful tips, information and suggestions for
the experienced operator. They are a necessary reference work for all
users. By reading the operating instructions
•Hazards will be avoided
•Operating sequences will be optimised and accelerated
•Repair costs and downtimes will be minimised
•Reliability and service life will be increased
The operating instructions should also be read carefully by the device
owners and managerial staff. In particular in relation to transport and in-
stallation, as well warranty aspects.
In chapter 2 important safety instructions and information about hazards
is given that will prepare you for hazardous situations that may occur.
Reading up during operation is unfortunately too late. Also note the fol-
lowing basic principle:
Cautious and careful working is the best protection from
accidents!
The quality of the tests performed using the device is crucially depend-
ent on maintenance and care. Regular maintenance work and care are
described in these operating instructions. If repairs are necessary, we will
be pleased to provide you with support and supply you with the necessary
original spare parts.

1.3 SHORT DESCRIPTION OF THE TESTERS
The tester G7-1G are designed for operation by using the integrated
touchscreen display and also via interface.
As an alternative, the device G7-1T are intended to be controlled using
an external PC/PLC. For this reason there is no display.
The modular design of the tester permits optimal adaptation to the indi-
vidual needs of the user. Expansion modules, standard accessories and
individual accessories offer the right solution for every application.
The basic devices available are automated devices (without display) for
use in test systems and „stand-alone“ devices (with display).
By optional features the devices can be equipped with additional functions.
The uses for the device family range from an individual manually operated
test bench, through a PC-controlled test station (with control, evaluation,
statistics and test plan management via PC software) to a complex fully
automatic test station with conveyor belt, autom. contact, labeling etc..
ELABO offers a modern software package for controlling this device series
and the management of the data via a PC.
Devices with touchscreen display
The user can be operated entirely using the touchscreen panel. This
operation covers the control of the device during the test, the generation
and management of test steps and test plans.
The display informs the operator at all times about the parameters and
the status of the tests.
HV part:
The device serves for the insulation test and withstand voltage test at elec-
trical equipment, machines, construction elements and insulating material.
The test is carried out with AC up to 5000 V/ test current maximal 100 mA.

1. INTRODUCTION
Combi-tester G7-1G/-1H/-1T/-1U
The electronic voltage ramp up makes it possible to perform tests on
electronic devices that can only be tested non-destructively by slowly in-
creasing the test voltage or on test objects with high self-capacitance. Due
to the fully electronically regulated test voltage, the variable transformer
otherwise used is not necessary. The current and voltage measurements
are made on the high voltage side. An integrated residual voltage meas-
urement ensures safe discharge of test object capacitance.
ISO (insulation) part
Insulation resistance measurement with voltages from 50 V to 1200 V DC
/current limited to maximal 1 mA.
Attention high voltage mortal danger! The resistance measurement is
not current-limited, it is performed with the full HV current.
Attention discharge currents - Danger for Life !!
Particularly valid for test objects with internal capacitance (capacitors).
Particularly if HV tests with direct current (DC) are performed, test ob-
jects with internal capacitances are capable of storing high charges. After
disconnection, these charges may be compensated via the body of the
operator (when touching the contacts).
If the test object remains connected to the HV tester sufciently long after
switching OFF the high voltage, it will automatically be discharged via the
HV-tester. Prerequisite for this: If discharging is prevented (disconnection),
"extremely dangerous discharge currents“ may be generated.
PE part
Measurements of the PE conductor resistance or the voltage drop at the
PE conductor are possible with a test current of 10 ... 32 A at a voltage
of 6 V or 12 V AC.
Function section (option):
Switching unit and power supply of the test object. Measurement of the
voltage, current and power consumption. Depend of the variation of the
function part, up to 3x 400 V/25 A.
PC software (option)
By controlling the tester via a PC/PLC all the advantages of modern soft-
ware can be exploited. Graphic, colour user prompts enable the operator
to see the status of the tests at a glance. Test parameters can be saved
in test plans, access control using passwords is possible. The test data
can be evaluated using Accept/Fault statistics. Other advantages are
the acquisition of barcodes using scanners, data integration via in-house
networks, communication with conveyor belt controllers, etc..
Important note: To connect the test object to the device, a connection
box or a connection panel is required. Another possibility is installation in
a test system (rack) with suitable power supply and switch panel.

as knowledge of the application regulations is able to assess the work
allocated and recognise possible hazards.

2.13 Information on the high voltage
Attention high electrical voltage - mortal danger!
IN DEALING WITH HIGH VOLTAGE THERE IS DANGER TO LIFE!
When performing tests using the device you will be working with a high
voltage up to 5000 Volt AC. If the device is tted with options, signicantly
higher voltages can occur. There is mortal danger when working with
high voltage!
Follow DIN EN 50191 (DIN VDE 0104). The EN standard regulates the
operation of test systems and test benches.
In the case of test voltages over 1000V the HV device must be equipped
with a warning lamp set (red and green lamps). See chapter 7.2 warning
lights.
Attention high voltage: The contact elements used for the HV and IS
test (test probes etc.) must be designed for the maximum voltage supplied
by the device.
2.14 Discharging test objects with internal capacitance
Attention discharge currents - mortal danger!! particularly in the case
of test objects with internal capacitance (capacitors).
Particularly during tests with DC, test objects with internal capacitance
can store large amounts of charge. After disconnecting, this charge
may be dissipated via the operator‘s body (if the test object is touched in
the appropriate place).
If the test object is left connected to the tester after switching off the high
voltage, it will discharge automatically via the tester. If this discharging
is prevented (disconnection), potentially fatal discharge currents may be
produced.

After the end of the test (end of test time), the test object connected is automati-
cally discharged. For this purpose a discharge resistor is connected internally
and the voltage across the resistor read (residual voltage measurement).
The discharging is undertaken using an internal resistor until a voltage of
3000 V is reached, the device then connects a 1 MOhm resistor in parallel.
If the voltage doesn‘t underrun a residual voltage of 60 V within - 10 s at DC
the device indicates the fault message „Attention residual voltage“.
Note: The residual voltage measurement can not switched off on the
„Setup“ menu or using an interface command.
Automatic discharging is performed only on HV-DC or ISO test. At HV-AC
test the high voltage is switched off on zero-crossing.
Attention: Leave the test object connected until it is discharged. The
device indicates this state with the illumination of the green RUN button.
Additional discharging via an external resistor
The device has an output for the connection of an external discharge re-
sistor. At the end of the HV/ IS test this output is connected by the device.
On this topic see chapter 6.2.5.1 „Outputs/external discharge relay“.

3 PUTTING INTO OPERATION
3.1 TRANSPORT AND INSTALLATION
The tester is supplied fully packed and is only allowed to be removed from
the packaging in the immediate vicinity of the installation location.
The device can be installed in a suitable industrial rack or housing for 19“
plug-ins. The device must be secured against unintentional movement.
The surface on which the device is installed must be appropriate for the
weight of the tester (approx. 30 kg!) and always provide a secure mount-
ing for the device.
During installation it is to be ensured the labels with information and safety
labels on the device are not covered.
To avoid an electrical shock because of condense water, the device should
have room temperature before the rst use.
3.2 AMBIENT CONDITIONS
The tester is not allowed to be operated in a dusty, inammable, aggres-
sive or humid environment. The values permitted for temperature and
atmospheric humidity are given in chapter 1.4 „Main technical data“.
3.3 INSTALLATION IN HOUSING OR RACK
Note: Slide the device carefully to the rear to the stop. Do not jam the
device on insertion.
After the inserting the device in a housing, it must be secured at the front
using 4 screws.
Operation with a loosely inserted tester is not allowed!
Installation without a modular system or housing is not allowed.
