POWER SUPPLY CONNECTION
When the load cell and the scoreboard display have been fitted and wired correctly,
switch on the power supply.
Once the power supply is switched on, the scoreboard displays the model reference
(e.g.HF 87/1) for 2 seconds, during which time the alarms are triggered and the
safety relays reversed.
Then, it displays a value in weight units. This value will only be correct after the
system has been calibrated). ( See page 14 )
Carry the test function out.

TEST FUNCTIONS
- The scoreboard display is supplied within 4 touch programming keyboard.
E
S
- Connect the keyboard to the RS 232 socket on the display.
This keyboard allows the following tests to be carried out :
- Display the signal from the load cell
Press the button to view the frequency signal from the load cell at that moment. Press the
button again to return the display of the load in kg. By default, the display returns to normal
after 4 minutes.
- Overload simulation
Press the button and hold it depressed, to simulate the overload condition. The two relays
are reversed and the alarms triggered.
- Display the parameters held in memory
Press the buttons and simultaneously. The scoreboard display will display the messages
in sequence :

SET.L
Set-up for Linearity Optimisation
Essential conditions :
x The load cell and display should be correctly mounted and wired.
x The hook of the lifting system should be free of any load.
Equipment required :
x A well-known load close to the maximum capacity of the lifting system. (Our example 9.975 Kg ).

The calibration has been successfully achieved.
REMARK : This calibration is recommended for weight estimation applications.
Basic calibration set the "zero point" corresponding to no load and a "maximum point" corresponding
to the well-known load.
Between those two points a « theoretical » straight line fixes the intermediary points, friction and
mechanical efficiency may lead to some linearity faults.
When high accuracy is required, complete the basic set up with : high accuracy calibration SET L.
