GENERAL CAUTIONS AND WARNINGS

THE CAUTIONS AND WARNINGS, SYSTEM SPECIFICATIONS AND USER INSTRUCTION SHEETS SHOULD
BE READ CAREFULLY BEFORE ATTEMPTING TO USE THIS 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. Cooper Instruments 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 therefore is
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.

Cooper Instruments 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
unauthorized personnel (without written authorization) 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. Cooper Instruments or other qualified engineering personnel should be
consulted before using the system to measure dynamic loads.

Avoid bending, side loading and off-axis loading.

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. Doing so might be dangerous.

CF 65 1 07.04.09 n.g.

Take particular care not to expose the system to nuclear radiation. Local environmental conditions such as extreme
temperatures (which exceed the temperature range stated in the system's specification), chemical materials, 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 explosion­proof and should not be used in hazardous areas.

System calibration should be performed annually, in an authorized laboratory, unless laws, regulations, or other
policies dictate alternative 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.

Unless otherwise specified, Cooper Instruments products are not legal for trade.

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

The Ron systems are prohibited by the manufacturer and/or seller to be used in any nuclear or similar site where
nuclear and/or radioactivity and/or ionizing radiation (henceforth radiation) exists. The Ron systems may not
function well in any space where radiation exists. If in spite of this warning the user will use the system in radiation,
he/she are 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 the user assumes
full responsibility and liability to waive any subrogation claim rights by the insurer to such claim against the
manufacturer and/or seller.

If you own several systems, make sure that

1.0 GENERAL DESCRIPTION

RON 2150 is available either as a Shackle or Hook Type. RON 2150 Shackle Type is a dynamometer with remote
display. RON 2150 Hook Type is a Crane Scale with remote display.

The system consists of a Load Cell and an indicator. These two items are designed to work together, providing the
versatility of two systems in one:

The system's indicator can be attached directly to the load cell, thus eliminating the need for an extension cable.
The indicator is securely attached to the load cell using a special latch that ensures the unit will maintain a safe and
reliable connection.

The system's indicator can also be detached from the load cell and held by the user. An extension cable designed
to connect the two devices is supplied with the unit.

It is recommended that the user either holds the remote indicator in his hand or view the large display from a
distance, so that under no circumstances will he have to approach the load in order to read the result. By this
means, the user’s personal safety is ensured.

The Indicator consists of a front panel with a 5 digit, 1” = 25mm liquid crystal display. The front panel also includes
a keyboard with five keys + a hidden (ESC) key: ON/OFF, TARE, ZERO, ENTER, MAX.. The hidden (ESC), the
ENTER key and the three arrow keys are only used during the calibration procedure, in the standard system.
Systems that have options like RS-232, totalizer and / or data logger include a keyboard of 10 keys.

CF 65 2 07.04.09 n.g.

The standard system is powered by internal, disposable 3xAA (finger) 1.5V Alkaline batteries. When using 3AH
rated batteries in continuous working, they will last for at least 2000 hours (more than two months). Occasional use
will extend the life of the batteries, up to several years.

Options:
The system options include:

1) Rechargeable batteries (instead of disposable), with a charger for charging the batteries inside the system.

2) A load cell with underwater capability.

3) A specially fitted carrying case.

5) Digital RS-232 output for communication with computers, printers or data acquisition devices.

6) Additional 2" (50mm) remote display with cable.

7) Analog output: 4/20mA, loop.

8) Analog output: 0/1V.

9) User-adjustable set points.

10) User-selectable baud rate.

11) User-selectable units.

12) Totalizer, for totaling-up accumulated loads.

13) Data logger: Stores time and data, up to 600 load measurements, with print capability.

14) Data logger with extended memory capacity, for storing, up to 3000 load measurements, with print capability.

15) Clock – real time clock.

2.0 OPERATION

Refer to the specification table regarding mating shackles. Attach the Load Cell taking care that the connector and
socket are lined up and exert gentle pressure until locked. When disconnecting, pull gently on the larger diameter of
the connector and this will free the locking device and allow the connector to be removed. Check that the cable is
free, without kinks, and cannot be trapped during operation. Connect the Load Cell, switch on the Indicator by
pressing the ON/OFF key until you hear the bleep and the display will then indicate the units in use. After pressing
the ON/OFF key, it will not accept an additional command for about 5 seconds.

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 measured value will then be displayed.

Before any loading, press the “ZERO” key until the word “zero” is displayed. The zero value will be displayed soon
after.

Please check that the indicator is in the “off” position after use.

When not in use, the system should be kept in its protective carrying case (if applicable).

When closing the carrying case, please ensure that the cable is not trapped. This could damage the cable.
*General remarks on operating the keyboard:

When pressing a key, the system responds with a short audio signal (beep) followed by a displayed sign. For
example, if one presses the MAX. key – the MAX. sign will be displayed. The key should be pressed continuously
until the visual sign appears. There is one exception: If several keys are pressed in sequence as part of a password
(code), during calibration, the visual signal will appear after completing the code, but the beep will follow each valid
key operation. If the code is not accepted, the “FAIL” sign will appear. In this case, a new attempt should be made.

CF 65 3 07.04.09 n.g.

3.0 TARE

The system features a Tare function that enables the user to ensure the display reads zero (0) even though there
may be a weight on the system such as slings or shackles or a receptacle. This capability makes the system easy
to use as it eliminates the need for the operator to subtract the weight of slings or shackles or a receptacle when
only the net amount of the load is required. Pressing the Tare button causes the display to blink twice “NET” and
then indicates 0000. To cancel the “NET” mode, press the “TARE” key until “GROSS” is displayed and then the
GROSS value will follow. The system blinks “NET” once every minute as a reminder that the mode in use is “NET”.
If one presses the TARE key when zero is displayed (0), the “NET” sign will appear on the display followed by the
“GROSS” sign. This happens because “NET and “GROSS” in this case are identical.

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

the

4.0 MAX. (=PEAK HOLD)

The system features a MAX. (=PEAK HOLD) function. MAX. is very useful when the maximum weight that the
system has detected must be known.

Press the MAX. key until the display shows “MAX.” and then the maximum load the system has encountered from
the last time the system was turned on, will be displayed for approximately 2 seconds. When active, 2 pairs of
flashing vertical points on the display will show the maximum weight detected and that the system is in MAX. mode.
MAX. can be manually reset at any time by turning the system off and on.

5.0 OVERLOAD WARNINGS

As a special safety feature, the system is designed so that the display will flash when the maximum permitted load
of the system has been reached. Should this occur, the lift should be terminated immediately by setting the load
down.

Should the system be drastically overloaded (133% of the system's capacity), “DANG.R”, which means “DANGER”
will appear on the display. Only when the system is completely unloaded will the “DANG.R” message disappear. In
this case, it is essential that the RON system, together with all loading / lifting devices, including rigging
accessories, be checked by an authorized inspector before it is used again.

Both of these situations are dangerous to personnel and should be avoided at all costs.
can also result in costly damage to the system. Even if the tare option is functioning, the circuitry is designed to
successfully detect an overload.

The overload value is always the Gross weight even if the system is in “NET” mode. This is the reason for having
an overload warning below the capacity value displayed when in “NET” mode.

Overloading the system

6.0 SLEEP MODE

After the display shows the value zero for a period of 60 seconds, the system enters sleep mode to save battery
energy. It checks if the value is still zero every 5 seconds. When it detects a non-zero value, it awakes.

7.0 BATTERY CARE

The standard system is powered by three AA (finger) size 1.5V disposable Alkaline batteries. They are fixed in a
battery rack inside a box in the lower part of the indicator.
