Chapter 29 Troubleshooting
This section of the Technical Reference Manual provides
information on error messages, trouble-shooting and
servicing the Model 574.
29.1 Error Messages (overview)
The following is a summary of all of the error messages
within the unit. They are listed below in numerical
order. The leading two digits will appear on the
numerical portion of the display, and the message will
appear on the two lines of dot matrix display. Following
each message is a summation of possible causes and
probable remedy.
29.2 Operational Mode Error Messages
02 UnderLoad! Input signal less than negative full
scale. If this is due to excessive
loading, reduce the load. Otherwise
check the load cell connections. If a 4
wire load cell cable is being used,
check that the sense jumpers are in
place. Verify that the capacity
selection P110 is correct. Use the
information parameters, especially
P61100, to check the setup and input
signal.
03 Over-Load! Input signal is greater than positive
full scale. Use same check as for
underload.
04 # > Dsply Number to be displayed will not fit
within 6 digits. This will not
normally occur for the Gross, Net or
Tare Weights but may result while
displaying the accumulated totals if
the amount exceeds 999,999. Either
clear the totals or settle for only being
able to transmit the totals.
05 Zero> Max.! An attempt was made to zero out more
than allowed per P118 selection. Use
the <TARE> key for subtracting off
container weights or if large dead-load
is always to be present, apply this
dead-load during the No Load?
prompt during calibration to
permanently eliminate the offset.
06 Tare>F.S.! Tare entry was greater than full scale.
Most likely the entered tare value was
incorrect.
07 Tare < 0 ! Negative tare attempted, but not
allowed per P162. For auto-tares, the
GROSS Weight must be greater than
zero unless P162 is changed to allow
negative tares.
08 CheckConn. This message is displayed if the signal
into the A/D is +/- 2 times the Full
Scale signal. This is effectively taken
into consideration when the
information sent to the micro
processor from the A/D is +/- twice
the allowable F.S. reading.
ie. P110 F.S. = 100
Error message will be displayed at +/-
208 taking into consideration the 4%
overload.
29.3 Setup Mode Error Messages
10 Entry>Max! An entry was made which
had more characters than
allowed. The most likely
cause in a model 574 would
be entering more than 242
characters into the input
interpreter table. Certain
parameter setups will also
display this message if the
entry exceeds the specifed
range of selections.
11 WRONGCODE! The incorrect access code
was entered, thus preventing
changes. In order to access
the Setup Mode, either the
proper code must be entered
or the <ENTER> key must
be pressed alone (to view
selections without making
changes).
12 No Mods! The Setup Mode is being
accessed, but changes are
prevented.
13 OutOfRange An entry made for a selection
