6.4 Error and information messages on the display
The integrated microelectronic in the LUB-V permanently monitors the status. In case of abnor-
malities, an addressed message is issued and shown on the display. If the LUB-V has detected
an error and issues an error message for better identification of the error, no more lubricant is
pumped. In addition, the screen saver changes and gives an indication of the type of error by
displaying the error number. The errors must be eliminated after they occur. If you operate the
LUB-V in the operating modes Hour mode or Empty time mode, errors must be acknowledged on
the display. If the LUB-V is operated in pulse mode, the errors can only be acknowledged by the
PLC by sending a specific signal, see Chap. 8.2.
