Troubleshooting
Operational Malfunctions
The operator/operating personnel must perform visual fill level
control of the lubricant reservoir at regular intervals. The control
intervals depend on the amount of lubricant required and the
pump's run time. The operator/operating personnel must
therefore determine the intervals on their own based on the
specific conditions of usage.
If the reservoir has been emptied, the entire system must be
ventilated after refilling (see assembly instructions).
All fault notifications are displayed by the LEDs
as a
centralized fault notification. When a fault notification 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 display. This greatly
simplifies failure diagnostics, though it requires system
monitoring.
Display Faults
•
Start the display mode with one of the two keys
•
Press the
key until you reach the fault notification (see
the following table)
Display
Explanation
Fault Cycle Switch: No signal from piston detector during pump cycle
(See "Pump Display Mode" on page 3-80.)
Fault Pressure Switch: No signal from pressure switch during pump cycle.
(Not applied to DOOSAN auto grease system)
Fault Low Level: The level in the reservoir has fallen below the minimum fill level.
The further operational sequence has been stopped.
