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

Display installation main steps :
1. Load cell installation and wiring.
2. Display installation and wiring.
3. Display calibration.
4. Safety trip points adjustment.
Definitions of the different calibration parameters :
nUL Set the Zero point of the measurement scale
SCAL Define the frequency ratio between zero point (
nUL ) and nominal
load value (
CALI ). Starting value: 7.000 Hz
CALI Define the nominal crane capacity e.g. : 20000 Lbs. Crane. Sheaved 4/1
CALI
= 20000
StEP Define the incremental steps of the display.
POId Calibration value regarding to a well-known load
SPEd2 Define the dynamic damper value
DBt
Double tare, return to the initial zero or the preceding zero
Complementary Advanced functions : high accuracy calibration
( Available from 4.2 software version only)
LIN
Linearity Optimisation
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.
