Xpu Error Code (Item Ep); Spu Error Code (Item Es) - Honeywell 854 ATG Series Instruction Manual

6.2 XPU error code (item EP)

The XPU error code is a three-digit number. When the XPU detects an error about a certain item, that item
follows the error code, separated by a space.
For instance: 067 LL :
Some XPU error codes of item EP are listed below, with suggestions for solving the problem. For a complete
overview, refer to "Item documentation for Honeywell Enraf series 854 ATG" and in the item help of the
service tool Engauge.

6.3 SPU error code (item ES)

The SPU error code is a four-digit number. Some SPU error codes of item ES are listed below, with
suggestions for solving the problem. For a complete overview, refer to "Item documentation for Honeywell

Instruction manual 854 ATG
invalid level format in item LL.
New software is installed; requires NOVRAM initialization
Set item 03 to '@'; check all settings, there may be an error
NOVRAM seize too small. Use XPU-1 board with larger NOVRAM seize
SPU board not well connected in backplane, or defective.
SPU board not well connected in backplane, or defective.
Jumper setting changed while power was on. Give reset (RS) command.
Missing SPU board or board not well connected in backplane, or defective.
Item not known to 854 ATG, check for correct item.
Wrong data field length, check for correct item setting.
First enter protection level 1 or 2.
Check item LD, then give the setting in the correct level format.
Check item DP, then give the setting with the correct decimal separator.
Give the setting in the correct floating point format (refer to section 3.3.3).
Command is currently disabled by the host command (HC)
Give the correct password for W1 and W2.
Password read access not allowed
The watchdog reset is a sign that there is a serious fault, caused by interference,
or a faulty XPU board.
Missing SPU board, or SPU board not well connected in backplane, or SPU
board defective.
Missing optional board, or optional board not well connected in backplane, or
optional board defective.
Serious internal XPU software error; check contents of item 00 and report to
Honeywell Enraf Delft.
Frequency constant 0 value is out of range (probably after NOVRAM init). Give
correct setting in item F0, or calibrate force transducer (refer to section 5.5).
The force transducer does not start-up correctly, or the motor unit has not been
unlocked.
A minimum correlation between the reference encoder table and the values read
from the actual reference encoder is not achieved. Either stepper motor or the
reference encoder is defective or filthy. Check motor and reference encoder
(excessive oil?).
Motor slack of more than ¼ revolution appeared. Recalibrate the gauge.
Frequency of the force transducer is too low
Frequency of the force transducer is too high
A wire rupture was detected or the motor unit has not been unlocked, or the
force transducer is defective.
Make sure that the mechanical moving parts of the gauge can move as
intended.
The wire tension has been too low for a while. Solve the problem or adjust item
ML.
The wire tension gas been too high for a while. Solve the problem; clean the
displacer.
