15. Operational and pump faults
15.1 KFGS operational malfunctions
15.1.1 General
The operator/operating personnel must
perform visual ill level control of the lubricant
reservoir at regular intervals. The control in-
tervals depend on the amount of lubricant re-
quired and the pump's run time. The operator/
operating personnel must therefore determine
the intervals on their own based on the speciic
conditions of usage.
If the reservoir has been emptied, the entire
system must be ventilated after reilling (see
Chapter 6, Assembly).
KFGS
All fault notiications are displayed by the LEDs
as a centralized fault notiication. When
a fault notiication is issued, the control unit
stops the normal operational sequence and the
fault that has occurred is saved and displayed.
The cause of the fault can be read on the dis-
play. This greatly simpliies failure diagnostics,
though it requires system monitoring.
15.1.2 Display faults

Start the display mode with one of the
two keys

Press the
key until you reach the
fault notiication (see following table)
15.1.3 Delete fault notiication

All fault notiications can be acknowl
-
edged and deleted using the
key. In timer
operation, this can also be performed using an
external pushbutton, if installed.
Warning!
Determine and remedy the cause of
faults before deleting fault notiications.
The user is liable for damages resulting
from operating the machine without
lubrication.
The time during which the control unit
and pump unit have been operated
without lubrication is stored as fault
hours
Fh in the EEPROM and cannot be
deleted.
Fault notification
Display Meaning
Fault Cycle Switch :
No signal from piston detector
during pump cycle
(see Chapter 9, Block Operation)
Fault Pressure Switch :
No signal from pressure switch
during pump cycle.
Fault Low Level :
The level in the reservoir has
fallen below the minimum fill
level. The further operational
sequence has been stopped.
