5.1. Installing the batteries

The three 1.5 V "AA" batteries are factory installed.
Remove the insulating tab protruding from the battery
compartment to activate the batteries. For subsequent
battery replacement, please refer to section 7.1. Battery
replacement.

5.2. Installation

During installation, it is absolutely necessary to:
1. Make sure that the load line anchor point or points
are sufficiently strong for the force that will be
applied.
2. Make sure that the lifting accessories at both ends
of the product are compatible and comply with
applicable local regulations.
3. Correctly lock the shackles by screwing their pin in
fully. Correctly lock the pear shackles by checking
the pins fit properly. Lock the clevis hook pin
correctly with its safety pin. Make sure that the hook
safety catch is present and in good working order.
4. Allow the product to line up freely in the line of force.
5. Check the presence and condition of the batteries
in the sensor.
6. Connect the product to the remote display unit or
to a smartphone via the Tractel app and to other
compatible display devices defined in paragraph 4.
Associated equipment.
7. Make sure there is a good radio link between the
sensor and the display box.
Use the product only with tensile force.
The product may be used in all directions, including
horizontally.
The product works satisfactorily in a temperature range
of -20°C to +50°C. For use beyond those temperatures,
the product must have thermal protection.

5.3. Starting up the sensor

Always switch on the sensor before switching on the
remote display unit, otherwise the remote display unit
will not be able to establish the radio link.
A light impulse on the start/stop button located in the
centre of the membrane activates the ON/OFF switch.
(See figure 5, item F.)
When the power is turned on, the two red LEDs start to
flash simultaneously.

5.4. Functions

5.4.1. Operation in basic configuration

Basic configuration consists in using a set made up of
a single sensor and a
single remote display unit, and/or a single sensor and a
smartphone equipped with the dynafor
measures and displays the force at the sensor.

5.4.2. Automatic zeroing

When the dynafor Expert is switched on, the associated
TM
display unit will show "0" providing the measured force is
less than 10% of the SWL of the product.

5.4.3. Information provided by the sensor LED

*The factory default setting is to switch automatically to economy mode if
there is no load variation (10% of SWL) for 5 minutes. This economy mode is
adjustable. See the dynafor HHD remote display unit manual.

5.4.4. Operation in multiple and extended
configuration
NB: For further details, please refer to the
associated equipment manuals defined in chapter 4.
Associated equipment.
The multiple configuration consists in connecting up
to four sensors and one or more display devices. The
sensors can have different capacities. (For more than
four sensors, the PC connection option is required.)
For some applications, it is useful to display the
measurements from several sensors on a single
dynafor HHD remote display unit.

Example: Lifting a load with a spreader bar suspended
from two winches, each equipped with a sensor. The
grouping together of the two force measurements on
a single dynafor HHD remote display unit allows the
TM
operator to view the two forces and their total value and
