14.2 Malfunctions on KFGS pump unit
All fault notifications are displayed by the
LED
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 di-
agnostics, though it requires system
monitoring.
