1 SAFETY
1.1 DESIGNATED USE
The Weatherford Load Cell M/B & Pancake is a measuring
cell for tension and compression force measurements, i. e.
to measure the Make-up or Break-out torque. It is designed
intrinsically safe and thus only for use in combination withintrinsically safe certified interfaces.
The mechanical interface (i. e. the pad eyes’ distance and
diameter) of the M/B type is designed to fit into most
Weatherford tongs, while the Riser type is designed
exclusively for the Weatherford Riser Tong. The Pancake
type can be used for general purposes, i.e. to adapt custom
type tongs to Weatherford JAM systems.
Using the Load Cell M/B & Pancake for purposes other than
mentioned above is considered contrary to its designated
use and is therefore prohibited. The manufacturer cannot be
held liable for any damage resulting from such use. The risk
of such misuse lies entirely with the user.
Never make any modifications, additions or conversions
without the manufacturer’s approval in writing.

2 TRANSPORTATION2.1 INSTALLATION
CAUTION
Never use a load cell with a measuring range
not corresponding to the torque of the tong.
If the range is too small, the load cell will be damaged due to
overload.
If the range is too wide, measurements will be incorrect and
tong handling problems such as overtorque may occur.
Best results are obtained if the maximum torque of the tong
is approx.15% less than the range of the load cell. Use the
following formula to determine the max. torque of the tongsuitable to the load cell:
max. Torque = LC range * Arm length
Example:
max. Torque [ftlbs] = 10 000 [lbs] * 3 [ft] = 30 000 ftlbs
max. Torque [ftlbs] = 10 [klbs] * 36 [in]/12 [in/ft]
= 30 000 ftlbs (inch converted to foot)

Use this version of the formula to determine the load cell
range suitable for a tong max. torque:
LC range = max. Torque /Arm length
Example:
LC range = 30 000 ftlbs/3 [ft] = 10 000 [lbs]
LC range = 30 000 ftlbs * 12 [in/ft]/36 [in]
= 10 [klbs] (inch converted to foot)

2.1.1 Tong type M/B – FF (free-floating Backup)
Install load cell according to the instructions in the tong
operating manual.
For make-up mode, it is usually installed on the left side
(tension measurement).
If at the same time a Martin Decker hydraulic load cell
is used, the Load Cell M/B can also be installed on theright side (compression measurement).
Install the electrical amplifier in such a way that the
connector and cable do not interfere with tong
operation, i. e. the cable usually leads to the rear.
Make sure to use the correct bushings (i. e. thebushings shipped with the Load Cell M/B) for the tong
in use. The type of bushings to use depends on the
size of the tong’s bolts.
Fasten the fixing nuts not too tightly. The pad eyes
must just allow a little movement.
WARNING
Make sure there is no bending moment at all on
the load cell.
This is to prevent damage that may cause
serious injuries.
When the load cell works in compression mode during break-
out, it may be subjected to a bending moment. If a load cell isbent, the measured values are incorrect. To prevent this; a pair

of special centering bushings is shipped together with all new
load cells. These must be in compression mode to prevent
incorrect measurements and possible damage to the load cell.
If your load cell was delivered without centering bushings,
contact Weatherford Germany for reworking.
2.1.2 Tong type with fixed Backup
Install load cell between the mounting bolt at the rear of
the tong.
Also read the instructions in the tong operating manual.
Install the electrical amplifier in such a way that the
connector and cable do not interfere with tong
operation, i. e. the cable usually leads to the rear.
Make sure to use the correct bushings (i. e. the
bushings shipped with the Load Cell M/B) for the tong
in use. The type of bushings to use depends on the
size of the tong’s bolts.
Fasten the fixing nuts not too tightly. The pad eyes
must just allow a little movement.

When the load cell works in compression mode during break-
out, it may be subjected to a bending moment. If a load cell is
bent, the measured values are incorrect. To prevent this; a pair
of special centering bushings is shipped together with all new
load cells. These must be used in compression mode to
prevent incorrect measurements and possible damage to the
load cell.
If your load cell was delivered without centering bushings,
contact Weatherford Germany for reworking.
2.1.3 Tong type without Backup
For this type install the load cell on the tong and fix it to
rig tie-off using a backup line and shackle.
Make sure that the angle between tong working
direction and the backup line is near to 90°, otherwise
there would be an increase of failure in measurement.
WARNING
Make sure the load cell does not touch the tongbody in order to prevent bending forces
affecting the load cell. If necessary, use asecond shackle at the tong.
Also, a twisting steel cable may cause a torsionmoment damaging the load cell. To avoid that,
use a swivel or install an additional hydraulic
load cell.
Incorrect measurement values may lead todamage and serious injuries.

2.1.4 Electrical Connection
After mechanical installation connect the load cell to the
torque measuring system using an Ex-proof load cell cable.
For JAMPro and ExTG, this cable is available as part no.
561 0901. For all others contact Weatherford Germany for
assistance.
2.1.5 Final Check
After installation and establishing the electrical connection,
check the load cell functions on the torque measuring
system (e. g. JAMPro, ExTG, HiPer). See the systemoperating manual for information on load cell indicator
settings, pipe data and torque values.

2.2 CALIBRATIONWe recommend to have the load cell always recalibrated by
Weatherford, Langenhagen, Germany. The ISO 9000-
certified service provides the best results.
However, if it is necessary to calibrate the load cell by
yourself, proceed as follows:
Make sure the following tools and accessories are on
hand:
• A programming tool, e. g. an USPI-H
(part no. 5614722).
• A certified weight corresponding to the max. torque of
the tong.
• A lifting device able to carry the full weight of the
entire system times 2.3 (safety factor).
• An ex-proof multimeter suitable for 4..20 mA.
Or:
• An LC Field Calibrator (part no. 561 5560 or
part no. 5615565).
Install the load cell in line with the certified weight or the
reference load of the LC Field Calibrator.
Connect the programming tool or the calibration
computer of the Field Calibrator to the load cell.
Check the communication between programming toolor calibration computer and load cell.

P a n c a k e
If you use a programming tool:
Check the zero point with no load. The multimeter must
indicate 4 mA. If it doesn’t, readjust the zero point.
For this purpose follow the instructions in the operating
manual of the programming tool.
Check the maximum value of the measurement range
by lifting the certified weight. The programming tool
must indicate 20 mA. If it doesn’t, readjust it.
For this purpose follow the instructions in the operating
manual of the programming tool.
If the measurement range was readjusted (see
previous step), repeat the zero point adjustment andthe maximum measurement range adjustment as
described in the previous two steps above.
If the software version of your load cell is older than
2.00, repeat the two adjustment steps as often as
required (usually once or twice) to obtain the setpoint
values within 0.5% tolerance of maximum torque.
If the software version of your load cell is 1.10 or higher
you have to carry out the above mentioned procedure
for tension and for pressure. For more details see the
operating manual of the USPI-H.

3 GENERAL DESCRIPTION3.1 LOAD CELL
The Weatherford Load Cell M/B is a general purpose
electrical measuring cell for tension and compression force
measurements. Based on the well-known strain gauge
method, it offers typically very good accuracy and
temperature behavior. The pad eyes are designed to fit into
most Weatherford tongs. Bushings for several bolt diameters
are included as accessories with the load cell. In such an
application the Load Cell M/B may be used to measure the
applied torque i.e. for JAM functionality.
The Load Cell M/B is available with the following electrical
interfaces:
• passive resistor bridge with 4- or 6-wire connection, to be
used with an external bridge amplifier (only on request)
• 4..20 mA interface with integrated amplifier with automatic
tension/compression switch
(normal interface, available by part no.)
The Load Cell M/B passive is designed for an operating
temperature range of -30° C to +70° C. The Load Cell M/B
active is designed for an operating temperature range of -
25° C to +70° C. The device is ATEX certified for gas
explosion protection type Ex ia IIC T4 for use inside
hazardous areas zone 1. The ambient protection class is at
least IP65 for use in rough environments. If connectors are

& P a n c a k e
not connected properly, protection caps must be used to
retain the protection class.
3.2 PASSIVE LOAD CELL
(available on request)
3.3 ACTIVE LOAD CELL
The integrated amplifier converts the sensitive strain gauge
bridge signal into a robust 4-20 mA current loop, which can
be utilized in the typical way using an intrinsically safe
current loop front end transmitter. A second circuit is
provided for communication with the integrated
microcontroller, i.e. to calibrate the load cell or to set the
mode (make/break). That control loop uses a special
Weatherford interface and can be used only in conjunction
with any Weatherford programming tool or field calibrator.
A typical disadvantage of all currently available loop load
cells is that they can measure only one direction of the
applied force, tension or compression. If the signal reachesvalues below zero (negative force) the resulting output
current falls below 4 mA and can not be recorded by typical
transmitters. Some cells are available with shifted zero point
to be able to measure also a force change, but this is not
compatible with industry standards and may therefore be a
source of problems.

The Weatherford Load Cell M/B Amplifier eliminates this
problem. In auto mode it detects the zero point and switches
its amplification direction accordingly. The result is always a
recordable 4-20 mA signal, which eliminates the need for
any further action if the usage is changed from tension to
compression and backwards.
This automatic mode is factory-preset. It is possible toswitch off the automatic mode and choose a dedicated make
or break mode. For that you need a Weatherford
programming tool or field calibrator. Once the automatic
mode is switched on or off, the load cell stays in this mode
until you decide otherwise, even after power up. The
programming tool or field calibrator also allows zero pointsetting and (in case of field calibrator) calibration factor
adjustment.
3.3.1 Software Version 1.04 or earlier
In automatic mode, if the current of the load cell drops below
3.7 mA for more than 1 s, the direction is changed. Then the
program waits for 1 s. Afterwards the check starts again.
If the automatic mode is switched off, the load cell switches
to make direction after power-up.
If your load cell is not equipped with a colored tag, you
probably have this software release. We strongly
recommend to contact Weatherford Germany for a

recalibration and software update at your earliest
convenience.
3.3.2 Software Version 1.05 or later
In automatic mode, if the current of the load cell drops below
3.95 mA for more than 20 ms, the direction is changed.
Then the program waits for 10 ms. Afterwards the check
starts again.
3.3.3 Software Version 1.08 or later
If the automatic mode is switched off, after power-up the
load cell switches to the last setting before power-down.
3.3.4 Software Version 1.10 or laterThese load cells have two different parameter sets, one for
tension and one for pressure.
3.3.5 Software Version 2.00 or later
These load cells have a new type of amplifier. One of the
advantages is that, if you calibrate the zero point or the finalvalue, these values do not influence one another. Therefore
the calibration cycle need not be repeated.

4 OPERATIONBefore operating the tong and the measurement system, the
measurement system must be calibrated and a functional
test of the tong must be carried out, preferably at the
workshop.
The functional test of the tong comprises of operating all
tong functions at least once. See the tong operating manual
for details.
Make sure all connections between tong and JAMPro are
established and the electrical power supply is switched on.
To operate the measurement system, also make sure to
follow the instructions in the JAMPro operating manuals.
5 PLACING OUT OF OPERATION
Disconnect all cables and uninstall the load cell. Mount the
protection cap of the socket.
Check the equipment for damage. Replace damaged
components immediately.
Keep all equipment clean and store it properly so that it is
ready for the next job.

6 SERVICE AND MAINTENANCEMost important is to keep the calibration of the load cell up
to date. We recommend to check and re-calibrate the load
cell at least annually. For this purpose we offer a calibration
service including a manufacturer’s calibration accuracy
certificate. If required we can also apply a state-controlled
certification to your load cell.
You can also calibrate the load cell by yourself using the
Weatherford load cell field calibrator, which includes the
mechanical setup with a reference load cell for the force
application and also a calibration computer to set up your
load cell and to document the measurement or calibration on
a PC.
Prevent trouble with the pad eyes of the load cell and grease
both pad eyes if dismounted.
Note that pad eyes not moving easily cause bending forces
and thus possibly incorrect measurements.

7 TROUBLESHOOTING In case of malfunction check the cable connections
first. If there is any damage, replace the cable with a
new one.
Then check for a mechanical problem.
Is the load cell mounted in the specified way? Look into
the corresponding tong operating manual. Use the
appropriate bushings to prevent damage.
Check if the electronics is working i. e. by connecting
another load cell to it.
If none of the above steps solves the problem, the load cell
itself may be damaged. Send it to Weatherford Germany for
repair.
The electrical measuring cell of the load cell contains no
parts which can be replaced by the user in case of
malfunction. It may only be repaired by the manufacturer.
Prevent trouble with the pad eyes of the load cell on next job. Keep load cell always clean if dismounted and grease
both pad eyes after each job.
