LSI-Robway RCI-1550 LM, Инструкция по эксплуатации, Страница: 44 / 97

Activate the viewing function for the transducer you want to check (if using two transducers they
must be checked in turn). Slowly luff the boom up and down through the entire working angle range
and observe the numbers shown in the display window.
The numbers displayed will be between 0 and 1023.
For correct operation the numbers must be
between 33 and 999.
If the transducers are working correctly you should see the numbers increase as the boom is being
luffed down and decrease luffing up. The value for an unladen boom will probably vary between
100 and 600, depending on the weight of the boom and attachments.
If the numbers go below 33 you should check for short circuits in the wiring from the transducer to
the ROBWAY indicator.
If the numbers are higher than 999 you should check for open circuit from the transducer to the
ROBWAY indicator.
If the numbers displayed stay within the 100 - 900 range then press the CANCEL button to exit
view mode and calibrate the transducers as described below. If the numbers do not change or fall
outside the valid range then check the wiring from the transducers to the ROBWAY display.
If the transducer signals check out then you need to calibrate them to force. This is done using a
ROBWAY transducer simulator and functions. Alternatively, you can just activate function code,
“ALTER CAL DATA”, and edit the “Cal Lo” and “Cal Hi” values of the Amplifiers.
 "CALIBRATE LOW END OF TRANSDUCER 1"
 "CALIBRATE HIGH END OF TRANSDUCER 1"

"CALIBRATE LOW END OF TRANSDUCER 2",
( only if using two transducers )
 "CALIBRATE HIGH END OF TRANSDUCER 2",
( only if using two transducers )
Please note that the ROBWAY simu lator has been designed t o
produce 2mv/V sign al w hen the switch is set to position 10
which is suitable for the majority of force sensing devices.
Some force transd ucers, ho wever, have a 3m v/V full scale
output.
The simulators can still be used for calibrating these devices,
however, w hen calibrating the full scale ( high ) end of th e
transducers you mu st enter 2/3 of the full scale force into the
ROBWAY system when the simulator is in position 10.
