24.3 Calibration Errors
These messages warn of incorrect calibration technique, or of attempts to calibrate the indicator beyond its
specification.
Error message Description
ZERO BAND The loadcell output is beyond allowable zero calibration range. Check for incorrect scale
connection. Change the dead load, or shunt the loadcells.
SPAN BAND The loadcell signal range (span) is too small or too large for these settings. Incorrect span
weight entered. Scale wiring incorrect. Incorrect loadcell capacity. Wrong or no calibration
weight added to scale.
This error is generated if:
There are less than 100 graduations
More than 5mV/V applied
Less than -5mV/V applied
Graduation of less than 0.005uV/V per div
24.4 System Errors
The condition of the internal circuits are continuously monitored. Faults or out-of-tolerance conditions are
shown on the display as an E type error message.
Errors are added together in hexadecimal:
Example 1: If the power supply voltage is low which causes a low excitation voltage, the error message
will be E00005 (00001
H
+ 00004
H
).
Example 2: The loadcell is not connected (i.e. both sense lines are disconnected). This will cause error
E000CO (00080
H
+ 00040
H
).
The numbers add in hexadecimal as follows:
1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 9 - A - B - C - D - E - F
For example:
2
H
+ 4
H
= 6
H
4
H
+ 8
H
= C
H
A
H
+ 2
H
= C

Error Description Action
E00001 The power supply voltage is too low Check power supply and cables
E00002 The power supply voltage is too high Check power supply and cables
E00004 The positive sense line is not connected Check the loadcell connection. This error
can be deactivated for EX-I applications with
OPTION:SENS.CH.
E00008 The negative sense line is not connected Check the loadcell connection. This error
can be deactivated for EX-I applications with
OPTION:SENS.CH.
E00010 The temperature is too hot or cold Check the location
E00020 Accessory module failure Restart. Replace faulty module
E00080 Resolution error Recalibrate indicator with valid resolution
E00100 The real time clock has failed Return for service
E00200 The setup and calibration information has been
lost
Recalibrate and reconfigure the unit
E00400 The factory information has been lost Return for service
