Error Messages with Ex Applications
In the event of load cell supply faults, the following error message is displayed:
E:Sense
(via VNC:
No sense voltage
)
Two different faults are possible, which are displayed by two LEDs on the weighing electronics board.
V120
V304
V120
lit:
Sense voltage is too low.
The cause can be a line break in the power supply and/or Sense lines.
V304
lit:
Current limiting for the load cell supply is active -> Sense voltage is too low.
The load cell supply current monitoring activates current limiting, if there is a short circuit in the
load cell supply lines, the load cell resistance is too low (e.g. too many load cells connected), see
also Chapter 3.2.8.2.
The current is limited to
96 mA.
After fault removal, current limiting must be de-activated. This can be achieved by switching off
the instrument and/or disconnecting the load cells.
