7 TROUBLE SHOOTING
RCS ‐ 110
Problem Cause To check How
Power Batteries Full or not? Replace
Accuracy User error Check if customer is
working the right
way. Is user doing zero check and zero correction
Is the mast vertical when weighing
Does the user weigh by lowering to reference
point at a speed that should be the same as
when the calibration was done. Best results are
obtained when lowering slowly to reference point.
Is the client weighing with the point of gravity in
the middle of the forks.
Side shift should be in the middle and not to the
extreme right or left.
.
No
repeatabilit
y over a
longer
period of
time
Check the zero point
by doing a weighing
action without weight
on the forks to see if
there is a zero
change. If this is the case, instead of zero the display
shows a positive or negative weight, it might be
necessary to correct the zero more regularly
New systems With new lift trucks, the friction in the mast may
change over the first few weeks and recalibration
may be needed.
A new sensor will become more stable after a
period of use.
Check if it may be
caused by change of
oil temperature.
Maybe rolls have too
much friction due
wear of rollers or dirt
in mast If accuracy changes after the truck is used for a
longer period of time the sensor maybe
temperature sensitive.
Check by lifting a weight that has been weighed
earlier that day.
Installation
error
Sensor
mounted
upwards See if connector /
cable is pointed
downwards Correct and turn sensor around.
Unstable Peak-hold

function
See if display
freezes and stable
weight is shown by: Lowering more briskly to reference point.
