Alarms
DeviceNet Error (DeviceNet Models Only): A problem in the DeviceNet communication is marked by a lack of
flashing or a slow flashing (duration about 0.5 s) of the DeviceNet status LED.
Profibus Error (Profibus Models Only): A problem in the Profibus communication is marked by a lack of
flashing or a slow flashing (duration about 0.5 s) of the Profibus status LED.
Ethernet Error (Ethernet Models Only): A problem in the Ethernet communication is marked by a slow
flashing (duration about 0.5 s) of the Ethernet status LED.
Modbus/TCP Error (Modbus/TCP Models Only): A problem in the Modbus/TCP communication is marked by
a slow flashing (duration about 0.5 s) of the Modbus/TCP status LED.
* For RIP remote displays, if the message exceeds 5 digits the display reads
------
.
In case of alarm the relays, not managed by Modbus, Modbus/TCP or DeviceNet, open.
In Analog Models only, if an alarm becomes active the relays open and the analog outputs go to the lowest
possible value according to the following table:
Display
Description
ErCEL
Load cell is not connected or is incorrectly connected; the load cell signal exceeds 39 mV; the conversion electronics
(A/D converter) is malfunctioning; the load cell is a 4-wire and there are no jumpers between EX- and REF- and
between EX+ and REF+.
Er OL
Weight display exceeds 110% of the full scale.
Er Ad
Internal instrument converter failure; check load cell connections, if necessary contact Technical Assistance.
---------
The weight exceeds the maximum weight by 9 divisions.
Er OF
Maximum displayable value exceeded (value higher than 999999 or lower than -999999).
t
------
Weight too high: zero setting not possible.
NAH-PU
This message appears in the test weight setting, in Weight (Span) Calibration, after the fifth test weight value has
been entered.
Err0r
The value set for the parameter is beyond the permitted values; press
to quit the setting mode leaving the
previous value unchanged.
Example: a number of decimals is selected for full scale which exceeds the instrument's display potential;
value above the maximum setting value; the weight value set in test weight verification does not match the
detected mV increase.
bLOC
Lock is active on menu item, keypad or display.
nOdl SP
It’s not possible to display the number properly because it is greater than 999999 or less than -999999.
