User manual
6.4. Error and information messages on the display
The integrated microelectronic in the FP 250/400 OLED permanently monitors the status. In case of
abnormalities, an addressed message is issued and shown on the display. If the FP 250/400 OLED 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 FP 250/400 OLED
in the operating modes lubrication cycle duration or emptying time, errors must be acknowledged on the
display. If the FP 250/400 OLED is operated in pulse control mode, the errors can only be acknowledged
by the PLC by sending a specific signal, see Chap. 8.2.

Check the lubrication point and
eliminate the cause.
Then trigger a Quick-Check for self-
testing of the FP 250/400 OLED or
disconnect the power supply.
Error E3

Error E4
Decive error
Disassemble the FP 250/400 OLED
and return it to the manufacturer together
with the lubricant cartridge and a
description of the fault.
A serious fault is usually in the
electronics of the FP 250/400 OLED and
cannot be repaired by you on site.
If the cause of an error message on the FP 250/400 OLED has been searched for, found and eliminated
and the error has been acknowledged on site or by the PLC, the FP 250/400 OLED automatically
returns to automatic mode. If the error message persists despite the elimination of the cause, or if it
occurs repeatedly, the FP 250/400 OLED must be sent to the manufacturer. To do this, disassemble
the FP 250/400 OLED and return it to the manufacturer together with the lubricant cartridge and a
description of the error.
