Return Codes
Name/Code #
Definition
Action
Command Success
command Status 0
Command passed
None
Command fail
Command Status 1
Command Failed. Applies to
pass/fail commands like C2 Search
Command specific. Reevaluate the
command and conditions.
ADC Convert error
Command status error 2
Statusword bit 0
Load Cell input out of range (i.e.,
voltage not 0-15 mV and flashing
red LED will display).
Can result from overloaded or
mismounted load cell. In this state
weight readings do not respond to
changes.
Check the voltage levels to the
module from each load cell. +5 V
for excitation and sense lines and 0-
15 mV on signal lines. If voltage is
bad, to find a problem load cell,
disconnect each one at the summing
box.
Statusword, bit 1 AC Convert
Failure
Output from the A/D converter to
processor is bad. The module shows
a solid red LED.
Contact Customer Support to return
module for repair.
Statusword bit 2 Status Motion
Command status error 4
The rate of scale weight change over
1 second exceeds the motion
tolerance setting. If the setting is
too low, motion may be indicated
when no changes are occurring.
If the weight is actually changing,
stabilize it. If not, increase
themotion tolerance setting until
the motion bit goes off with static
weight.
Statusword bit 3 EEPROM write
error
Module cannot write (save settings)
to non-volatile memory. EEPROM is
probably bad.
Contact Customer support to return
module for repair.
Statusword bit 4 Status Center Zero
Indicates the gross weight is reading
at the calibration zero point.
None
Statusword bit 6 In Progress
Command Status 0xFF
Command is in progress.
None
Statusword bit 7 not found
Command Status 0x80
The parameter ID is invalid
Correct the parameter ID
Command Status 5 No C2
When trying to do a C2 calibration,
the module cannot read the data
from the load cells.
Check the wiring to ensure proper
connections and orientation. Find
the problem load cell by
disconnecting them at the summing
box.
Command Status 6 C2 Capacities
not equal
C2 load cells have unequal
capacities due to either the use of
mismatched load cells or faulty C2
programming.
Verify each load cell is correct per
the spec sheet delivered with the
cell.
Command Status 7 C2 clones
C2 load cell has a non Hardy C2 load
Verify the use of Hardy load cells.
