General Cautions and
Warnings
The following cautions and warnings, system
specifications, and user instruction sheets should be
read carefully before attempting to use this Eilon
Engineering product.
Products are supplied with the express understanding that the purchaser and/or user
are thoroughly familiar with their correct application and proper use. Eilon
Engineering will assume no responsibility for the misuse or misapplication of any of
its products.
In addition to these guidelines, the user must also comply with general safe operating
practices when using the system e.g. when weighing during lifting.
The load limit rating, a.k.a. capacity, indicates the maximum force or load a system can
carry under normal working conditions. Overloading or placing a load on the system
above its rated capacity is dangerous and is therefore STRICTLY PROHIBITED
except during the system's annual safety testing. This testing must be performed by
qualified personnel and allows the system to be overloaded up to 25% of its rated
capacity, no more than once per year.
Eilon Engineering will accept no liability for damage caused by the product being
used in excess of the working load limit or from abuse.
Opening, attempting to open, or any attempt to repair the system by unauthorized
personnel (without written authorization) will nullify the warranty as well as the
manufacturer's liability and could be dangerous. Refrain from doing so and contact an
Elion representative should any problem with the system arise.
When measuring loads using a shifted zero with the tare function, the actual load is
the value indicated on the readout plus that of the shifted zero or tare.
For best results, it is recommended to turn your system on 10 minutes prior to
measuring.
The system is designed for static loading. Eilon Engineering or other qualified
3
engineering personnel should be consulted before using the system to measure
dynamic loads.
Avoid bending, twisting, side loading and off-axis loading.
When connecting the load cell in order to measure forces or loads, special care should
be taken in choosing appropriate shackles or other connecting accessories that will
permit free movement and prevent bending moments and twisting in the load cell.
Always use shackles with a S.W.L. (Safe Working Load) equal to, or greater than the
system's rated capacity.
Check the system thoroughly before use, including the lifting accessories which are
included with some Ron systems. Do not use a damaged system.
We recommend that the system is checked occasionally by lifting a known weight.
Further, the system should be sent back to the manufacturer or to an authorized
service center for general examination once every year.
System calibration should at first be performed annually in an authorized laboratory
unless local laws, regulations, or other policies require alternative intervals. Once the
user becomes familiar with the particular needs of their system, the need for
calibration may vary.
Between calibrations, the user can verify whether the systems are still calibrated
correctly by using a known weight.
Calibration verification and adjustment must be performed with extreme care. An
erroneous calibration adjustment will result in false readings, which could be
dangerous.
If there is any doubt as to the reliability of the load indication, do not use the system
with an unknown load. To check its reliability, use a known load preferably with a
value of more than 50% and less than 100% of the system’s rated capacity. Never use
a weight that is more than the rated capacity.
The permitted temperature range appears in the Ron system specifications.
Do not allow the system to overheat or fall below the minimum permitted
temperature, as doing so may be dangerous and cause damage.
Take particular care not to expose the system to ionizing radiation.
4
Local environmental conditions such as extreme temperatures (those that exceed the
stated temperature range in the system specifications), chemical materials, radio
transmissions or other magnetic radiation may interfere with the system's reliability
causing a false reading which could prove dangerous. Avoid using the system under
such conditions.
The system is not explosion-proof and should not be used in hazardous areas.
Unless otherwise specified, Eilon Engineering products are not legal for trade.
Each system consists of a load cell with its own indicator (excluding 1000 & 4000
models).
Important: If you own several systems, make sure that each load cell is used with its
original indicator. Load cells and indicators are calibrated as matched pairs and are
non-interchangeable.
Important:
At all times, it is the responsibility of the user of this equipment to ensure that normal
safety precautions are observed. No amount of safety features and engineering can be
a substitute for common sense and a desire to work safely.
The Ron 2501 relies on wireless communication. Like all wireless devices it is
susceptible to interference and other reception issues.
The system will display TR.ERR during such communication problems. When
TR.ERR is displayed the system will be unable to detect overloads. We recommend
that a prolonged TR.ERR be handled as if an overload was occurring.
Take extra care when TR.ERR is displayed.
Ron systems are prohibited by the manufacturer and/or seller to be used in any
nuclear or similar site wherenuclear and/or radioactivity and/or ionizing radiation
(henceforth radiation) exists. Ron systems may not function well in any space
whereradiation exists. If despite this warning the user uses the system in radiation,
he/she is waiving any right of claim against the manufacturer and/or seller concerning
direct or consequential damages or loss resulting from the use of Ron systems in
violation of the above restrictions, and theuser assumes full responsibility and liability
to waive any subrogation claim rights by the insurer to such claim against the
manufacturer and/or seller. This restriction does not apply to areas that are deemed
safe for people to work in.

2. Basic Operation
Basic operation of Ron systems and helpful tips and tricks
Before operation, be sure the shackles you intend to use are appropriate for the
system (see shackle specification table). Press the key to turn the system on. The
display will read BATT, then the percentage of remaining battery life of the indicator
and then the load cell, followed by the unit of measurement.
M. TON (Metric Tons)
S. TON (Short Tons, American tons, 2000 Lbs)
LBS
K.NTON (Kilo Newton)
DECA.N (Deca Newton)
N.WTON (Newton)
KG
The current weight value will then be displayed.
Before loading the system, press until ZERO is displayed.
The system should then read GROSS then 0.
Once use of the system has been completed, press the key to power down.
Return both the load cell and indicator to their carrying case or another appropriate
safe place of storage.
2.1 - General operation of the keyboard:
When pressing a key, the system responds with a short audio signal (a beep) followed by
a change to the display. For example, if one presses the key, MAX will be displayed.
The key should be pressed continuously until the beep is heard. Exceptions are turning
the system on or off which does not require a long press. Also, when several keys are
pressed in sequence as part of a code during calibration, the visual signal will only appear
8
upon completion of the code, but the beep will still follow each valid key press. If the
passcode is not accepted, the display will read COD.E.R. In this case, a new attempt
should be made. (See Calibration for more.)
2.2 - Tare
Switching between Gross and Net modes
The system features a Tare function that enables the user to ensure the display reads 0
even though there may be weight on the system such as from a sling, shackles or a
container. This capability makes the system easy to use as it eliminates the need for
the operator to subtract the weight of the container, etc. when only the net amount of
the load is required.
To use the tare mode, load the system with the desired container and then press .
The screen will display NET, then the value of 0. The system is now in Net mode. To
exit out of Net mode, press again. GROSS will appear indicating that the
system is back in Gross mode. The system will show NET on the screen about once
every minute as a reminder that it is in Net mode. Note that switching between Gross
and Net modes will clear the MAX (see MAX section).
CAUTION:
When measuring loads using a shifted zero applied and/or with the tare function
applied, the real load is the value indicated on the readout plus that of the shifted zero
or tare. Take this into account to avoid accidental overloads.
2.3 - Max (a.k.a. Peak Hold)
Checking the maximum registered load value
The system features a MAX (aka PEAK HOLD) function. MAX will store the
maximum weight that the system has detected since it was last powered on or since
the Gross/Net mode was changed.
Press the key until the display shows :M:AX. It will then display the current
maximum load the system has registered since the last time the MAX was reset. The
weight will be displayed for approximately two seconds with colons in between the
digits. These simply serve as a visual indicator that the displayed value is the stored
9
max and not the current weight. The system will go back to the current value then a
beep will sound indicating that the system is ready for a new operation.
The MAX memory is cleared every time the system is powered down or the mode is
changed between Net and Gross or Zero is applied. The MAX will also be reset if the
unit of measurement is changed (see UNITS section).
2.4 - Overload Warnings
Two level visual overload warning
The system features a two level visual overload warning. When loaded to 100% of its
maximum capacity and up, the displayed weight will flash on and off continuously.
Should this occur, the lift should be terminated immediately and the current load set
down.
Should the system be drastically overloaded (130% of max capacity), DANGER
(short for danger) will appear on the display. Only when the system is completely
unloaded and the measured value reduced to zero will the DANGER message
disappear.
Should this occur, it is critical that the Ron system and all accompanying rigging
accessories are checked by an authorized inspector before being used again.
The system will display TR.ERR during communication problems. When TR.ERR is
displayed the system will be unable to detect overloads. We recommend that a
prolonged TR.ERR be handled as if an overload was occurring.
Take extra care when TR.ERR is displayed.
Please note that both overload warnings remain functional at the same levels (100% &
130% of full capacity) whether the system is in Gross or Net mode. This means that
when TARE is used, you may see an overload warning at a displayed value that is less
than 100% of capacity.
All overloads are dangerous to personnel and should be avoided at all costs.
Overloading the system can also result in costly damage to the system itself.
10
2.5 - Battery Care
Maintenance of Ron 2501 batteries for top performance
The standard system is powered by two AA 1.5V disposable alkaline batteries in bothe
the indicator and load cell.
Batteries rated 3AH will result in at least 2000 hours of battery life (more than two
months of continuous use). Occasional use will extend the battery life up to several
years. Optional extended battery life: 4000 hours.
The display will show LO:BAT when the batteries need to be replaced. Once
LO:BAT is displayed, you still have several hours of operation left. If the battery level
gets too low, the system will automatically power down in order to avoid damage from
low voltage.
When the system is turned on, the batteries' energy level is displayed as a percentage
e.g 100%. Battery level can also be checked from the menu.
Replacing the batteries
Indicator:
Use a screwdriver to remove the back cover of the indicator. Gently remove the
battery holder from the indicator being careful not to damage the wiring. Replace the
batteries with two fresh AA 1.5V disposable alkaline high quality high energy batteries.
Load Cell:
Use a screwdriver or your thumbs to loosen the screws of the panel on the back of the
load cell.
Accessing the battery compartments
11
2.5.1 - Rechargeable Batteries
Though we recommend standard alkaline AA batteries, rechargeable batteries are
offered. This option includes 2 AA NiMH 2700 mA rechargeable batteries. The
system is supplied with a external wall charger.
The batteries should be charged:
1. Prior to using the unit for the first time.
2. Before use, if more than two months have passed since the last charge.
3. When LO:BAT (low battery) is displayed on the screen.
A full charge will take 10-14 hours.
Store bought rechargeable batteries may be used. Choose NiMH AA size 1.2V
rechargeable batteries (minimum 1800mAH or higher) and a standard charger.
Due to the difference in battery voltage, rechargeable batteries will display a biased
energy level. For example, fully charged NiMH batteries will only show an energy
level of 80% rather than 100% and will normally show a value about 20% less than
the actual level.
WARNING
It is dangerous to charge disposable batteries and may result in the batteries
exploding. If you are using disposable batteries in a system sold with
rechargeable ones, please remove the charger from the system's carrying case
or place of storage in order to prevent potential accidents.

3. Calibration
Performing additional calibration and adjustment to the system
Note
It is recommended that calibration be performed by authorized and skilled
personnel only! It should be performed using an accurate known weight or in a
laboratory.
Unless otherwise required by local laws, it is recommended that the system be
calibrated annually. The weight used in the calibration must not exceed the system's
capacity.
3.1 Best Practice for Calibration
It is recommended that calibration and adjustment are performed using a known weight that
is 80% of the system's maximum capacity. This will give the best and most accurate results.
A known weight between 80% – 100% of capacity may be used but never a weight greater
than the capacity.
It is recommended that the system be turned on for at least 10 minutes prior to calibration.
If the system includes a dampened display/averaging, the dampening should be shut
off before calibrating (see Dampened Readings section). The system is protected by
two different codes to prevent calibration by unauthorized personnel.
