2.3 Power

Press

to turn on the Dyna-Clamp. The startup sequence displays all LCD segments, followed briefly by the software

version number and the battery volt level. After the startup sequence is complete, the primary display area of the Dyna-Clamp enters tension mode.

2.4 Wire Rope Selection
Press F1 ( by default) with the current wire rope value displaying in the secondary display area to toggle through the available wire rope options. The wire rope selection needs to be made before Zeroing the Dyna-Clamp.
The F1-key is setup as Active Function () by default. See Section 3.3 on page 7 to program the function keys.
Note
The F2-key is setup as Scroll () by default and scrolls through the secondary (top) display area options.
The Dyna-Clamp is factory calibrated for up to eight (8) wire rope diameters. Calibrations may only be performed by Rice Lake Weighing Systems. Please contact Rice Lake Weighing Systems for calibration assistance or if additional wire rope calibrations are required.

2.5 Zero

Press

when the Dyna-Clamp is not under tension to remove small deviations of the zero reading. Zero on location, just

prior to positioning the Dyna-Clamp on the wire rope. Re-zero the Dyna-Clamp each time the wire rope selection is changed.

Note The Dyna-Clamp must be held horizontally by the carrying handle. The load cell mount assembly must be fully

suspended and not in contact with any surrounding surfaces or objects before pressing

. The unloaded

indication on the display will vary slightly depending on orientation. This variation is negated once under tension.

2.6 Tension Measurement

The following procedure describes how to connect the Dyna-Clamp to a wire rope to take a tension reading. The Dyna-Clamp can be used to monitor the tension of a wire rope for maintenance and installation applications.

IMPORTANT

Always ensure that the wire rope is centered on both bobbins and never use the Dyna-Clamp on a wire rope diameter over 1”. Regularly apply moly grease to the drive rod threads to maintain proper lubrication.

1. Loosen the drive rod. 2. Zero the Dyna-Clamp (Section 2.5).

Wire Rope Bobbin

Mount Assembly Top

Drive Rod End Drive Rod

Figure 2-2. Dyna-Clamp On Wire Rope
3. Position the Dyna-Clamp on the wire rope (Figure 2-2).
Note Position Dyna-Clamp directly to the wire rope, at least two feet from any attachments or the termination points.
4. Roll the Dyna-Clamp 6-8” back and forth along the wire rope to align the unit to the center of the wire rope. 5. Tighten the drive rod assembly firmly, torquing the drive rod to approximately 60-100 in-lb. Drive rod assembly should
be tightened until the rope contacts the stop block and the handle becomes hand tight; be careful not to “crush” the rope by over-tightening. The optimal torque rating varies depending on the wire rope diameter and construction.
IMPORTANT Do not over tighten the drive rod. Over tightening could cause damage to the wire rope or the Dyna-Clamp.
6. Take the tension reading from display. See Section 2.7 on page 5 for how to use the Average Function. 7. Loosen the drive rod assembly and remove the Dyna-Clamp from the wire rope. 8. Repeat Steps 3-7 to take additional tension measurements as needed. For the best accuracy take at least three
tension readings at slightly different locations along the wire rope using the Average Function (Section 2.7 on page 5).

Operation

2.7 Average Function
The average function allows the operator to combine multiple tension measurements and displays the average in the secondary (top) display area.
Note The following procedures assume that the F-Keys are still programmed to the default settings with F1 set to
and F2 set to . See Section 3.3 on page 7 to program the F-Keys.

2.7.1 Average Procedure Follow this procedure to utilize the average function:
1. Press F2 until Avg displays to the right side of the secondary display area.
2. Position the Dyna-Clamp on the wire rope and allow a few seconds for a stable reading.
3. Press F1 . This takes the current display value to be included into the running average.
4. Remove the Dyna-Clamp from the wire rope. Additional values can not be added to the running average until the Dyna-Clamp has been removed from the wire rope and the live tension reading passes below a low % of capacity. This is by design to prevent averaging the same load more than once.
5. Repeat Steps 2-4 as needed.

2.7.2 Clearing Average Follow this procedure when the running average needs to be cleared:
1. Position the Dyna-Clamp on the wire rope and tighten slightly, so a little positive tension is measured by the device.

2. Press F1 , followed quickly with pressing

to clear the current average register.

3. Remove the Dyna-Clamp from the wire rope and re-zero (Section 2.5 on page 4).

2.8 Peak Function
The purpose of the peak function is to take and record the greatest tension that is applied. Press the F-Key until Peak displays to the right side of the secondary display area. As long as Peak is displayed, the secondary display area continuously displays the greatest tension that has been measured.
2.8.1 Clearing Peak Press F1 ( by default) with the peak value displaying in the secondary display area to reset the peak function.
Note Changing from one wire rope setting to another will automatically clear both the average and peak values.

2.9 Safety Strap
The Dyna-Clamp has a slot and hole on either side of the display to accommodate the attachment of a safety strap.
2.10 Carry Case Option
A hard-sided carry case (PN 198418) is available as an option to provide more protection and security when transporting the Dyna-Clamp tension meter.

3.8 Battery Life
The battery life parameter () offers a standard mode () and a long battery life mode (). When in the long battery life mode, the system is placed into a sleep state if there is no change in tension after a period of time. This disables the display in order to reduce power consumption and increase the battery life. The unit does not enter the sleep state if it is in the setup menu. The auto-off parameter (Section 3.4 on page 8) also conserves battery life by turning the unit off if no activity is sensed for a set time.

Note

The standard mode ( ) is recommended for best performance. Long battery life mode ( ) does not affect accuracy, but may impact performance and usability.

4.2.1 Disposable Batteries
Low Battery displays when the battery is getting low. When Low Battery starts to blink, the batteries are close to being drained. For maximum life, use the batteries until the system shuts off.

4.2.2 Rechargeable Batteries When using Nickel-Metal-Hydride (NiMH) cells, it is recommended that the cells are recharged immediately after Low Battery starts to blink. Do not allow the batteries to discharge completely, it may compromise the recharge life of the battery.
NiMH Cells have a lower capacity than Alkaline. Having two sets of NiMH batteries is recommended, so one set can be charging while the other is in use.

IMPORTANT

The use of NiCad batteries is not recommended.
Remove the batteries prior to storing to prevent possible battery corrosion if the Dyna-Clamp is not going to be used for an extended period of time.
