3 Basic instructions
3.1 Proper use
The balance you purchased is intended to determine the weighing value of material
to be weighed. It is intended to be used as a “non-automatic balance”, i.e. the
material to be weighed is manually and carefully placed in the centre of the weighing
pan. As soon as a stable weighing value is reached the weighing value can be read.
3.2 Improper Use
Do not use balance for dynamic add-on weighing procedures, if small amounts of
goods to be weighed are removed or added. The “stability compensation“ installed in
the balance may result in displaying an incorrect measuring value! (Example: Slowly
draining fluids from a container on the balance.)
Do not leave permanent load on the weighing pan. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of the balance,
minus a possibly existing tare load, must be strictly avoided. Balance may be
damage by this.
Never operate balance in explosive environment. The serial version is not explosion
protected.
The structure of the balance may not be modified. This may lead to incorrect
weighing results, safety-relat ed faul ts and destruction of the balanc e.
The balance may only be used according to the described conditions. Other areas of
use must be released by KERN in writing.
3.3 Warranty
Warranty claims shall be voided in case
• Our conditions in the operation manual are ignored
• The appliance is used outside the described uses
• The appliance is modified or opened
• Mechanical damage or damage by media, liquids, natural wear and tear
• The appliance is improperly set up or incorrectly electrically connected
• The measuring system is overloaded
AEJ-C/AES-C/PLJ-C-BA-e-1514 17
3.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the
balance and, if applicable, the testing weight, must be checked regularly. The
responsible user must define a suitable interval as well as type and scope of this test.
Information is available on KERN’s home page (www.kern-sohn.com with regard to
the monitoring of balance test substances and the test weights required for this. In
KERN's accredited DKD calibration laboratory test weights and balances may be
calibrated (return to the national standard) fast and at moderate cost.
4 Basic Safety Precautions
4.1 Pay attention to the instruc t ions in the Operation Manual
Carefully read this operation manual before setup and
commissioning, even if you are already familiar with KERN balances.
All language versions contain a non-binding translation.
The original German is binding.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
5 Transport and storage
5.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
5.2 Packaging / return transport
Keep all parts of the original packaging for a possibly required return.
Only use original packaging for returning.
18 AEJ-C/ AEJ-C/AES-C/PLJ-C-BA-e-1514
Prior to dispatch disconnect all cables and remove loose/mobile
parts.
Figure example KERN AEJ/AES-C
Reattach possibly supplied transport securing devices.
Secure all parts such as the glass wind screen, the weighing
platform, power unit etc. against shifting and damage.

20 AEJ-C/ AEJ-C/AES-C/PLJ-C-BA-e-1514
6 Unpacking, Setup and Commissioning
6.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing results are achieved in
common conditions of use.
You will work accurately and fast, if you select the right location for your balance.
Therefore, observe the following for the installation site:
• Place the balance on a firm, level surface;
• Avoid extreme heat as well as temperature fluctuation caused by installing
next to a radiator or in the direct sunlight;
• Protect the balance against direct draughts due to open windows and doors;
• Avoid jarring during weighing;
• Protect the balance against high humidity, vapours and dust;
• Do not expose the device to extreme dampness for longer periods of time.
Non-permitted condensation (co nd ens a ti on o f air humidi ty on the appliance)
may occur if a cold appliance is taken to a considerably warmer environment.
In this case, acclimatize the disconnected appliance for ca. 2 hours at room
temperature.
• Avoid static charge of goods to be weighed or weighing container.
If electro-magnetic fields or static charge occur, or if the power supply is unstable
major deviations on the display (incorrect weighing results) are possible. In that case,
the location must be changed.
6.2 Unpacking and checking
Remove device and accessories carefully from packaging, remove packaging
material and place device at the planned work place. Verify that there has been no
damage and that all packing items are present.
Scope of delivery / serial accessories:
• Balance, see chap. 2
• Mains adapter
• Operating manual
• Protective cover
• Flush-mounted hook
• Transport locking device (models AEJ-C and PLJ-C)
AEJ-C/AES-C/PLJ-C-BA-e-1514 21
6.3 Placing
Remove transportation lock (only models AEJ-C and PLJ-C)
To detach transport locking device, unscrew locking screw.
For transportation screw in locking screw carefully right up to the limit stop.
• Level balance with foot screws until the air bubble of the water balance is in the
prescribed circle
• Check levelling regularly
22 AEJ-C/ AEJ-C/AES-C/PLJ-C-BA-e-1514
Models AEJ/AES-C
• Open glass wind screen on all sides
• Place protection sheet (1) into the weighing chamber

• Place wind shield (3)
24 AEJ-C/ AEJ-C/AES-C/PLJ-C-BA-e-1514
6.4 Mains connection
Power is supplied via the external mains adapter. The stated voltage value must be
the same as the local voltage.
Only use original KERN mains adapters. Using other makes requires consent by
KERN.
6.4.1 Turning On the Pow er
• Supply balance with power via the mains adapter. The display unit lights up and
shown the software version. The weighing scale carries out a self-test and
automatically moves into weighing mode.
When „CAL“ appears on the display, an automatic adjustment will take place
(only models AEJ-C and PLJ-C).
6.5 Connection of periphera l devi c e s
Before connecting or disconnecting of additional devices (printer, PC) to the data
interface, always disconnect the balance from the power supply.
With your balance, only use accessories and peripheral devices by KERN, as they
are ideally tuned to your balance.
6.6 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have
reached the operating temperature (see warming up time chap. 1).
During this warming up time the balance must be connected to the power supply
(mains, accumulator or battery).
To adapt the balance to ambient conditions, open wind screen doors.
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Adjustment.
AEJ-C/AES-C/PLJ-C-BA-e-1514 25
7 Adjustment
As the acceleration value due to gravity is not the same at every location on earth,
each balance must be coordina ted - in compliance with the underlying physical
weighing principle - to the existing acceleration due to gravity at its place of location
(only if the balance has not already been adjusted to the location in the factory). This
adjustment process must be carried out for the first commissioning, after each
change of location as well as in case of fluctuating environment temperature. To
receive accurate measuring values it is also recommended to adjust the balance
periodically in weighing operation.
Possible adjustments include:
• Automatic adjustment by internal weight (models ILJ only)
Chap. 7.2.1
• Manual adjustment by internal weight is triggered by pressing CAL
• Adjustment with external weight, see chap. 7.2.2
• Adjustment can only be carried out when the weighing pan is free of objects.
Any loads remaining on the weighing pan will be indicated by error message
Er1Hi.
• You can cancel the adjustment by pressing the UNIT-key.
26 AEJ-C/ AEJ-C/AES-C/PLJ-C-BA-e-1514
7.1 Automatic adjustment with internal weight (only AEJ-C and
PLJ-C)
With the internal adjustment weight, the weighing accuracy can be checked and readjusted at any time.
The automatic adjustment function is always enabled. You can start adjustment at
any time by pressing the CAL-key manually.
If a load is present on the weighing plate, the message LIMIT EXCEEDED will
appear on the display. If the weight on the weighing plate is below 10% of max, the
weighing scale nevertheless will be adjusted.
Automatic adjustment is carried out:
• When balance was disconnected from the mains.
• When the temperature is changing
The moment a change in temperature of 3°C is detected by the temperature
sensor, the weighing scale will carry out a fully automatic adjustment. The °C
symbol indicates the pending adjustment.
• at the end of a time interval
After the time interval (selectable 1-12 h) specified in the menu has passed.
In weighing scales with type approval certificate
• Adjustment takes place every 3 hours
In the following operating modes the automatic internal adjustment is disabled:
• Parts counting
• Tolerance weighing
• Dosing
• Percent determination
