GENERAL CAUTIONS AND WARNINGS

THE 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 the
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 practice, and when using the systems for weighing during lifting, the user
must also comply with safe operating practice during lifting.

The load limit rating (or “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 annual safety testing of the system, to be performed
by qualified personnel, when overload of up to 25% of rated capacity is permitted.

Eilon Engineering will accept no liability for damage caused by the product being
used in excess of the working load limit (capacity of the system) or from abuse.

Opening or attempting to open the systems and, needless to say, any attempt to
repair the systems by unauthorised personnel (without written authorisation) will
nullify the warranty as well as the manufacturer's liability, and could be dangerous.

When measuring loads using shifted zero or tare, the actual loading is the indicated
value (the readout) plus the value of the shifted zero or tare.

The system is designed for occasional, not continuous, use. If the system is to be
integrated with equipment that performs continuous loading over extensive periods
of time, then use of a system with at least 30% higher rated capacity (load limit) is
necessary. For example: a 3t crane should be used with a 5t load system.

The system is designed for static loading. Eilon Engineering or other qualified
engineering personnel should be consulted before using the system to measure
dynamic loads.

Avoid bending, side loading and off-axis loading.

Eilon Engineering Ltd. RON 2501 NG Operating Manual 4

When connecting the load cell in order to measure forces or loads, special care
should be taken to choose the right connecting accessories that will permit free
movement and prevent bending moments in the load cell.

Use shackles with S.W.L. (Safe Working Load) equal to, or greater than the
system's maximum capacity.

Check the system thoroughly before use, including the lifting accessories which are
included in some of the RON systems. Do not use a damaged system.

We recommend that the systems be checked occasionally by lifting a known
weight.

We recommend that the systems be sent back to the manufacturer for general
examination once every year.

Do not use the system with an unknown load if there is any doubt as to the
reliability of the load indication. To check its reliability, use only a known load
with a value of more than 50% and less than 100% of the system’s rated capacity
(load limit).

The permitted temperature range appears in the RON systems specification.
Do not allow the systems to overheat. This could be dangerous.

Take particular care not to expose the system to nuclear radiation.
Local environmental conditions such as extreme temperatures, radio transmissions
or other magnetic radiation may interfere with reliable system operation and may
cause a false (low) 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.

System calibration should be performed annually, in an authorized laboratory,
unless laws, regulations, or other policies specify other intervals for calibration.

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 since
a wrong calibration adjustment will result in false readings, which could be
dangerous.

Eilon Engineering Ltd. RON 2501 NG Operating Manual 5

Unless otherwise specified, Eilon Engineering products are not legal for trade.

Each system consists of a load cell with its own indicator.
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.

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.

1. GENERAL DESCRIPTION:

RON 2501 is available either as a Shackle or Hook Type.

RON 2501 Shackle Type is a Dynamometer with remote wireless display.

RON 2501 Hook Type is a Crane Scale with remote wireless display.

The RON 2501 consists of a Load Cell and an Indicator. These two items are

designed to work together.

The indicator is held by the user, so that under no circumstances will he have to
approach the load in order to read the result. By this means, his personal safety is
ensured.

Communication between the load cell and the indicator is wireless. The effective
transmission range is 50m under normal working conditions. This feature enables
the system to be used in hot industries and in circumstances where using a cable is
not possible, or is inconvenient.

The load cell panel includes an ON/OFF button. When the load cell is

functioning correctly the red light on the panel flashes briefly at approximately 5

sec. intervals.

The indicator includes a control panel and a display.
The standard control panel has six push-buttons to operate and program the system.
It also includes the hidden key “ESC”.

Each standard system offers these push-button features:
On/Off
Zero
Tare (100% of capacity)
MAX (=Peak hold)
User calibration

The 5-digit display provides the following information:

* The measured load
* Two level overload warning
* Max. value (= Peak hold)
* Low battery warning for both load cell and indicator
* The following modes: SLEEP, TARE, NET
* The units in use (Lbs, Kgs, etc.)
* Instructions during programming procedure etc.

2. BATTERY CARE AND MAINTENANCE

The standard system is equipped with disposable 1.5V (“finger”) type Alkaline
batteries fixed in special battery racks. The load cell contains 4 and the indicator 3.
The battery rack is located in the lower part of the indicator.

To replace batteries, press the two small latches on both sides of the lower part of
the indicator. The battery rack is just behind the lower indicator box cover that is
released by the two latches.
The load cell batteries can be replaced by opening the four Philips screws securing
the body cover – the one without the antenna.

Use high quality, high energy Alkaline 1.5V AA size batteries.
