TROUBLE SHOOTING
ERROR
DESCRIPTION
ACTION TO CARRY OUT
EFFECT
SOLUTION
Unstable weight: the
weight value shown
goes up and down
steadily
Weight drifts: the
weight shown either
increases or
decreases steadily
ErrorH: Scale out of
range for positive
values
ErrorL: Scale out of
range for negative
values
For Graphic models: keep the
key T/CLEAR pressed.
For HL models: press T/CLEAR
and then Enter.
The message
ERROR disappears
and the weight
becomes stable.
The scale was out o frange; by pressing
the key T/CLEAR the problem was solved
through the scale software.
Either the message
ERROR is still
shown on the
display, or the weight
is visualized in an
unstable way.
Check the integrity of the weighing system
and of the load cells. To better understand
what is broken, carry out the action
described in the next point.
Disconnect the 5-pin connector
(metal circular connector) of the
load cell cable from the scale.
Weight still fluctuates
/ drifts / shows
ERROR.
Check if the 5-pin female connector of the
scale has humid contacts. If so, use warm
air to dry off the connector (use for
instance a hairdryer). If after this operation
the weight still fluctuates, contact service.
Weight gets stable,
even though a wrong
value is shown.
Carry out the action described in the next
point:
Disconnect the junction cable
from all the load cells and
reconnect the 5-pin connector to
the scale, avoiding the contact
between the different connection
wires.
Weight still fluctuates
/ drifts / shows
ERROR.
Check if the cable is damaged; if so,
replace it. Check if the junction box
contains humidity; if so, dry the junction
box.
Weight gets stable.
The reason of the problemi s that one or
more load cells do not work properly. To
better understand the cause of the failure,
carry out the action described in the next
point.
Set the tare to zero on the
weighing computer (by pressing
the key T/CLEAR for Graphic
models, by pressing T/CLEAR
and then Enter for HL models).
Wait for some seconds. Connect
one single load cell to the
junction cable, by connecting
each single wire colour by colour,
and pay attention that the wires
do not touch each other.
Weight still fluctuates
/ drifts / shows
ERROR.
The connected load cell doesn't work
properly; contact service.
Weight gets stable.
The load cell doesn't work properly;
disconnect the load cell and connect
another one. This operation must be
repeated for all load cells.
Weight fluctuates, is
not stable while
working only.
Make sure that the cables of the
load cells are not torn or crushed.
The cables are
seriously damaged
or broken.
Replace the damaged cables.
The cables are
intact.
Carry out the action described in the next
point:
Check that the tank, or the device
receiving the weight, does not
touch the frame in any point.
The tank lays on the
frame.
Arrange for the tank not to touch the frame
in any point.
The tank does not
lay on the frame.
Contact service.
