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:
ˆ
There are less than 100 graduations
ˆ
More than 5mV/V applied
ˆ
Less than -5mV/V applied
ˆ
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:
ˆ
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
).
ˆ
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
