Error Display List
When either of the following errors occur, the RUN signal of an external output is turned off.
■
Torque display section
-LOAD
Below the signal input range
-5V
The input electric signal greatly exceeds the signal input
range. This also occurs when an excessive load is applied to
the sensor or the input terminal is opened due to a break in
the cabling, etc..
+LOAD
Beyond the signal input range
+5V
ALM HI Beyond the alarm HI limit This occurs when a larger load than expected is applied to
the sensor or calibration is performed below the
measurement range.
Check the calibration and measuring object.
ALM LO Below the alarm LO limit
OFL1 Below -99999 This occurs when a larger load than expected is applied to
the sensor or calibration is performed below the
measurement range.
Check the calibration and measuring object.
OFL2 Beyond 99999
cErr2
Beyond the zero calibration
range in the positive direction.
The signal input range is greatly exceeded when zero
calibration is performed. Check for an excessive load
applied to the sensor and for breaks.
cErr3
Below the zero calibration
range in the negative direction.
cErr4
Beyond the rated output value
in the positive direction/
negative direction.
Beyond the rated capacity
value.
The signal input range is greatly exceeded when calibration
is performed. In the case of equivalent input calibration,
check the rated output value, and in the case of actual load
calibration, check for an excessive load applied to the sensor
and for breaks.
Also, Check the setting of rated capacity value (display
value) sets it exceeding "± 99999".
cErr5 Rated capacity value = 0
Check the setting of rated capacity value (display value) for
being "0" when calibration is performed.
cErr6
Rated output value 0.000V at
the time of equivalent input
calibration.
Rated output value in the range
of -0.010 to +0.010V at the time
of actual load calibration.
Check the rated output value for being 0.000V when
equivalent input calibration is performed, and the load for
being too light in weight when actual load calibration is
performed.
DZ Err Digital zero limit error
When the range of zero point correction (deviation from the
zero calibration registered point) by digital zero or zero
tracking exceeds the setting value of digital zero limit,
digital zero limit error occurs. Perform digital zero, etc., in a
proper range.
LO BAT
Lithium battery backup voltage
drop
The voltage of the lithium battery for internal memory
backup has dropped. The battery needs to be replaced. Ask
us for replacement of the battery.
