•Designed for use with U.S. made Crosby shackles (optional).
•Shackle holes reinforced with steel sleeves (25000 lb/12500 kg capacities and above) to reduce wear.
•Shackle stops ensure ease of mounting. The stops prevent the shackles from falling to the side of the unit and
are held in position for easy rigging.
•ScaleCore technology provides precision, high resolution (2500 division standard, up to 10,000 possible) 24
bit A/D conversion coupled with an advanced RISC micro-controller. ScaleCore technology provides quick
and easy firmware updates, setup, calibration and backup.
•Five, 1.22'' (31 mm) LCD digits for clear tension readings from a distance. Six digits, 1'' (26 mm) on units
100,000 lb and over.
•Easy to maintain. Full digital calibration ensures reliable, repeatable measurements. Can be calibrated without
test weights using C-Cal technology.
•Selectable kg/lb/tons (U.S. Short)/metric tons/kilonewtons.
•Automatic or manual weight totalization for loading operations.
•Easily customized for special applications.
•Hi speed peak mode for stress and drop test analysis.
•Two setpoints can be set for any in-range tension/weight value for operator alerts or process control. Optional
audible alarm output.
•Two service counters ensure load train safety by warning the user to perform safety checks when the lift count
gets high or the Dyna-Link 2 has been overloaded repeatedly. Counter 1 (Lift Count) records the number of
lifts above 25% of capacity. Counter 2 (Overload Count) records the number of times the unit was
overloaded.

2.0 Operation
This section includes the basic operation of the Dyna-Link 2.
2.1 Power
Turn on the Dyna-Link 2 by pressing POWER . The LCD displays all segments for a display test and the software
version number will briefly display. When is displayed, the unit is ready for use.
2.2 Zero
Press
ZERO
to remove small deviations in zero when the Dyna-Link 2 is unloaded. See Section 2.3 on page 6 for
zeroing (taring) package or pallet weights.
Note
•Zero works in GROSS or NET modes.
•Zeroing while in NET mode will zero the gross tension causing the display to show the negative tare value.
•TheDyna-Link 2 must be stable within the motion window. The unit will not zero until is displayed.
The unit holds a zero request for two seconds. If the motion clears in that time, the unit will zero.
•The unit will accept a zero setting over the full range of the Dyna-Link 2. Zero settings above 4% of full
capacity will be subtracted from the overall capacity.
Example:
If 100 lb is zeroed on a 1000 lb Dyna-Link 2, the overall capacity will reduce to 900 lb plus the allowed

over-range amount.
The tension reading must be stable within the motion window for the zero function to work.
The backup memory stores the zero reading in the event of power failure.
2.3 Tare
2.3.1 Tare and Display the Net Tension
1. Program an F-key to TARE. See Section 4.2.5 on page 10.
2. Press the Ta re F-key. is displayed and the tension mode changes to NET.
The tension reading must be stable within the motion window for the tare function to work. The backup memory
stores the tare reading in the event of a power failure.
2.3.2 Clear the Tare and Revert to Gross Tension
Press the Tare F-key. The NET annunciator turns off. The absence of the NET annunciator is the only indication the
Dyna-Link 2 is in the GROSS tension mode.
Note
To view the GROSS tension without clearing the tare value, program the remaining F-Key to the function
NET/GROSS.
• Only positive gross tension readings can be tared.
• The tension/force reading must be stable and must be on.
• Setting or changing the tare has no effect on the gross zero setting.
•TheDyna-Link 2 stores the tare value in non-volatile memory and is restored when power is cycled.
• Taring will reduce the apparent over range of the Dyna-Link 2.
Example:
When taring 100 pounds of rigging on a 1000 lb Dyna-Link 2, the unit will overload at a net tension of 900
lb (1000-100) plus any additional allowed overload (usually about 4% or 9d).

Installation 7
3.0 Installation
3.1 Unpacking
When unpacking the Dyna-Link 2 from the shipping container, ensure that all assembly parts are accounted for.
Check for any visible damage and immediately report any damage to Rice Lake Weighing Systems and the shipper.
Retain the original shipping container for future shipping or transporting of the unit.
3.2 Assembly
Two cotter pins and two batteries are included with the Dyna-Link 2, also required for installation are shackles and
pins, they can be supplied by the customer or they can be ordered from Rice Lake Weighing Systems. See Table 1-
3 on page 5.
Note
1. Slide top shackle over load cell and insert the pin.
2. Screw the shackle nut onto the pin.
It is not necessary to tighten the nut too tight. Ensure the nut is down far enough to expose the cotter pin hole.
3. Lock the shackle pin in place with the supplied cotter pin and bend the cotter pin.
4. Repeat steps 2-3 for the bottom shackle.
5. Remove the battery access port cover.
6. Insert the two batteries, positive end first, into the battery shaft.
7. Reinstall the battery access port cover.
The Dyna-Link 2 is now ready for use.
WARNING
Note
The unit will automatically start when the batteries are installed.
The Dyna-Link 2 load train is unsafe for use if the shackle pins are not properly secured with cotter pins.
3.3 Battery Replacement
Disposable Batteries
The BT annunciator will display when the battery is getting low. When the BT annunciator starts to blink, the
batteries are close to being completely drained. For maximum life, use the batteries until the system shuts off.
Rechargeable Batteries
When using Nickel-Metal-Hydride (NiMH) cells, it is recommended that the cells are recharged immediately after
the BT annunciator starts to blink. Do not allow the batteries to discharge completely as this may compromise the
recharge life of the battery.
NiMH Cells in C and D sizes have a lower capacity then the Alkaline C and D sizes. Rice Lake Weighing Systems
recommends having two sets of NiMH batteries, so one set can be charging while the other is in use.
Important
NiMH D cells are often repackaged C cells. Therefore there is no increase in battery life for Dyna-Links
large enough for D cells.
The use of NiCad batteries is not recommended.
If the Dyna-Link 2 will not be used for an extended period, the batteries should be removed.A small current is used
when powered off which will discharge the batteries in about six months.

4.2.3 Total
Note
1. Ensure the total mode has been programmed in the setup menu. If this has not been setup the F-Key assigned to
TOTAL will not work.
2. Program an F-key to Tota l. See Section 4.2 on page 9.
3. Press Total F-key to perform the total function that was set in Section 4.5 on page 13.
This feature should not be confused with the ttl.rd (Total Remote Devices) function, which will add weight
from two or more load sensors.
4.2.4 Net / Gross
Press the NET/GROSS F-key to switch between gross and net mode. The NET/GROSS F-key only functions if a tare
value has been established. The operator can switch back to gross from net without clearing the tare value. Only
clearing the tare, or setting a new tare, will change the tare value held in memory.
4.2.5 Tare
Press the Ta re F- key to tare out a known force, only positive and negative deviations from the tared force display.
In force measurement applications, tare is useful as a way to display differential force. It also increases accuracy as
any initial error is removed leaving only slope error.
In scale applications, tare is typically used to zero out a known weight such as rigging, a packing container or
pallet. Once zeroed, the load displays in NET tension/weight. To use tare, set an F-key to the TARE function.
• A tare value is entered by pressing the TARE F-key.
•The
TARE function in the Dyna-Link 2 is defined as a tare-in/tare-out operation.
• The first press of the TARE F-key stores the current tension/weight as a tare value. The Dyna-Link 2
subtracts the tare value from the gross tension and changes the display to NET mode.
• The next press of the TARE F-key will clear the tare value and revert the display to GROSS mode.
• The optional RF remote display has a TAR E key permanently available.
4.2.6 Peak Hold
The Peak Hold function uses a high speed mode of the A/D converter allowing it to capture transient tensions at a
far higher rate than typical dynamometers.
Note
• Peak hold is cleared and enabled with the PeakHold F-key.
• When a new peak is detected, the F-key LED will flash three times.
• The accuracy of the system in peak hold mode is slightly reduced to 0.2% of capacity ± 5d.
• The filter setting is turned off while in peak hold mode to ensure the fastest acquisition rate.
Example:
The Peak Hold function is useful in materials and fall tests. Common tests include Overall Breaking Strain
(OB€), Breaking Force, and Cycled Breaking Strain.
Capture Peak Force
1. Program an F-key to PeakHold. See Section 4.2 on page 9.
2. Prepare the test stand and test a sample.
3. Press to zero out any residual strain on the link.
4. Press the PeakHold F-key. The Pk annunciator displays.
A small jump in the reading may occur depending on the stability of the test stand.
5. Apply the test force. The PeakHold F-key LED will blink tree times for each peak it detects.
6. Remove the test force and record the peak value.
7. Press the PeakHold F-key to clear the peak value.
8. To run a new test, confirm Pk is not displayed. Repeat steps 1 through 6.

Setup 11
4.2.7 2-Units/ 5-Units
Program an F-key to either 2-UNIT or 5-UNIT. See Section 4.2 on page 9.
Press the 2-UNIT F-key to switch the force units between lb and kg.
Press the 5-UNIT F-key to scroll through all available units: lb, kg, tons (U.S. short), metric tons, and kilonewtons.
4.2.8 Hi-Res
Program an F-key to Hi-Res. See Section 4.2 on page 9.
Press the HiRes F-key to display the high resolution mode. The display will stay in high resolution mode until the
HiRes F-key is pressed again, or the power is cycled. While in the hi-res mode, the appropriate HiRes F-key LED will
blink continuously at a slow rate.
Hi-res mode does not increase the accuracy, but allows for smaller weight increments to be displayed.
Use Tare or to zero out any initial error. Hi-Res mode will make the Dyna-Link 2 more sensitive to motion
and movement resulting in a less stable display. When Hi-Res is on, the filter is automatically set to the Hi-1 setting
(if Hi-2 is already set, then the filter is not changed). This will have a small effect on settling time. When Hi-Res is
turned off, the filter setting resets to the previous filter setting.
4.2.9 Print
Program an F-key to Print. See Section 4.2 on page 9.
Press the Print F-key to output a configured text string to the RS-232 port on the base of the unit.
If a Print F-key is programmed and the print setup is configured as continuous, then the Print F-key is used for Start
Print/Stop Print. See Section 6.3 on page 24 for more details on data output.
The print function is always available on the optional RF remote display, so it is not necessary to program a 
Print F-key if print outputs will be triggered from the remote.
If the RF remote display option is installed, the Dyna-Link 2 built in comm port is used only for hard-wire
connections to the RF remote display or firmware updates.
4.3 Auto Off
The Auto Off feature prolongs the life of the battery by turning the power off when the Dyna-Link 2 is not in use.
Any key press or detected tension in motion exceeding 10d, resets the time limit and the unit remains on.

4.5 Total
For the accumulation of multiple weighments, the Total function uses the displayed load, so gross and net readings
can be added into the same total.
There are four modes of totalizing, a manual and three auto modes.
All modes require that the weight on the scale return below 0.5% (relative to full scale) of Gross Zero or Net Zero
before the next weighment can be added. Applied weight must be ≥1% of full scale above Gross Zero or Net Zero
before it can be totaled.
Manual Total
Manual Total () adds a current weight to a previously accumulated value manually. To add weight to the total
it must be greater than 1% of capacity and not yet totaled. This assures that a weight on the scale is only added to
the total once.
Note
1. Program a F-key to . See Section 4.2 on page 9.
2. With the weight to be added on the scale, press F-Total. The acknowledge LED blinks to indicate the weight
was accepted and the TOTAL annunciator lights. Then the total weight is displayed for five seconds and the
number of samples is displayed for two seconds.
3. Repeat steps 1 & 2 until all weight samples have been added.
Total Mode will not function while the scale is in motion, ensure is on. If the system fails to achieve
stable readings, increase the filter setting or increase the size of the scale division (d) in the Init Cal procedure.
The F-Total functions as View Total only until the 1% threshold is exceeded to allow the addition to the total
value.
Auto Total
This mode has three variations which are programmed in the Setup menu.
Program an F-key to AUTO TOTAL, it functions as Auto Total On / Auto Total Off. See Section 4.2 on page 9.
Table 4-3. Auto Load Selections
 Auto Load – ensures any settled load above the Rise Above threshold will be automatically totaled. The scale must fall
below the Drop Below threshold before the next total is allowed.
 Auto Last – takes the last settled weight to auto total with. The total occurs only once the scale goes below the
threshold. This allows the load to be adjusted without a total occurring. Once the load is removed, the scale uses the
last settled reading for total.

Auto High – uses the highest settled reading. This is useful for loads that can’t be removed all at once.

4.6 Filter
Changing the filter settings allows the Dyna-Link 2 to adjust to situations where there is a lot of movement in the
lift or the crane structure. If the reading is not stable, it can often be improved by increasing the filter setting.
Settling time will be longer as the filter setting is increased. The Dyna-Link 2 employs algorithms that speed up
large tension changes while still controlling vibration even with higher filter settings.

5.0 Calibration
The Dyna-Link 2 is calibrated using standard precision test weights. It is required that the weight used is at least
10% of full capacity in order to achieve rated accuracy.
Example: Use at least a 500kg test weight to calibrate a 5000kg capacity unit.
The Dyna-Link 2 supports load cell linearization with up to four span points that can be calibrated in any order.
Usually only one cal span point is necessary and is sufficient to reach rated accuracy.
When adequate test weights are not available, the Dyna-Link 2 can be calibrated using a Constant Calibration 
(C-Cal). To use C-Cal, the factory generated C-Cal number must be known. MSI supplies original and replacement
load cells for the Dyna-Link 2 with the C-Cal value stamped on the serial number label.
There are three types of calibration:
• Standard calibration is used for maintenance and routine calibration. See Section 5.1 on page 16.
• Initial calibration is used to setup both the capacity and resolution (d) of the Dyna-Link 2. It differs from
standard calibration only in the initial steps. Initial calibration is performed after a calibration reset which
completely erases the calibration and parameter settings.
• C-Cal can be used if C-Cal values are known, the Dyna-Link 2 can be calibrated without weights.
The calibration menu contains three items: Cal, C-Cal, and Setup. The following procedures start with entering into
the Cal menu, or for an initial calibration, resetting the Dyna-Link 2 and then going to the Cal menu.
Table 5-1. Calibration Menu
Standard and initial calibration parameter. See Section 5.1 on page 16 and Section 5.2 on page 17.
C-Cal parameter. See Section 5.3 on page 19.
See Section 5.4.1 on page 20 and Section 5.4.2 on page 20.
Industrial Standard Settings
The common setting for the MSI-7300. With the Industrial standard, the unit has full range
zero, access to units switching, filters, and peak hold.
Sets the scale to enable only approved features per the NTEP HB-44 rules and regulations.
Access is denied to Peak Hold, and the zero range may be limited. The Filter menu is moved to
the Cal Setup Menu, so filters are only accessible through the Cal Seal.
Sets the scale to enable only approved features per OIML R-76. Only kg weight units are
available. The zero range is limited to 5% (-2 +3% relative to Calibrate zero). Net/Gross function
is temporary. Once Net weight is established, pushing an F-key set for Net/Gross will cause a
maximum 5 second display of the Gross weight. The Tare must be cleared to display Gross
weight constantly. Other meteorological aspects are changed to meet R-76 requirements.
The one unit standard is exactly the same as Industrial, except unit switching is inhibited. This
is useful for Metric only countries. Another use of the One Unit standard is to allow the scale to
be calibrated in units other than lb or kg, since conversions are eliminated.
