5. OVERLOAD INDICATOR

"DANGER"

6. OPERATION

The LLX1 system has 16 separate radio channels. The LLX1 sensor and the LLX1 display unit must use
the same channel in order to communicate. The LLX1 display unit only allows reading a single LLX1
sensor at a time. Up to 16 LLX1 systems, each using a specific radio channel, can be operated
simultaneously on a single site.
See details in § 7.1: Synchronisation of an LLX1 system.

6.1 Commissioning

6.1.1 Enabling the sensor batteries

The 3 x 1.5 V "AA" batteries are installed in the factory.
Remove the insulating tab protruding from the battery compartment to enable them.
For future replacement of the batteries, refer to the LLX1 operation and maintenance manual.

6.1.2 Charging the display unit

The display unit is delivered with the power pack charged.
Afterwards, use the charger provided to charge the power pack.
Charging time: 3 h.
The display unit can be used during charging.

6.1.3 Turning on the sensor

"DANGER"
To start up the sensor, refer to the LLX1 operation and maintenance manual.
When the load applied to the sensor exceeds the maximum capacity
of the appliance of 10 % (e.g.: a 25 t loaded at 27.5 t) the display unit
indicates an overload message "HI" as shown opposite, and emits an
intermittent beep.
If several sensors are connected to the display unit, the overloaded
sensor will be immediately identified.
In the example display opposite, relating to a two-sensor set up, the
sensor on the second line is overloaded.
In the event of overload, all stress on the sensor must be
completely relieved and a check made that the appliance
returns to zero.
If the appliance shows a stress value, even though tension
is not applied, then it has suffered a permanent distortion.
In this case, you must have the appliance serviced by the
manufacturer before continuing to use it.
Always switch on the sensor and wait for the end of the initialisation
sequence before you switch on the display unit; otherwise, the display
unit will not be able to set up the radio link.
We recommend that you check, and if necessary, modify the
measurement units so that the same units are used on the two devices.
