15.2.6 Remedy faults
Always check cables irst when a fault
occurs. Most signal cables are moni-
tored for breakage, so a defective cable
or loose contact can cause a fault
notiication.
When a warning occurs, it is recom-
mended that the system be stopped
and the fault be remedied.
When a malfunction occurs, the fault
must be remedied immediately in order
to prevent damage to the machine and
the associated risk of accidents.
After the fault has been remedied and
before operation is resumed, the
key
must be pressed or the equivalent CAN
command sent to reset the system's
fault status and delete the fault notiica
-
tions.
15.2.3 Fault types
Depending on the severity of the fault, the
control unit issues either a warning or a mal-
function notiication (see following table).
15.2.4 Fault notiication
Warnings
are indicated by a constant
LED light. At the same time, the fault notiica
-
tion is stored in the FRAM.
Malfunctions
are indicated by a lashing
LED light. At the same time, the fault
notiication is stored in the FRAM.
15.2.5 Read faults
All fault notiications generated during op
-
eration are stored in the control unit's FRAM
together with further system parameters and
a timestamp. They can then be read from the
FRAM. This allows each failure to be uniquely
identiied by its code. Refer to the "LC-
CAN5000 - Coniguration and Control Inter
-
face Protocol" manual for more information.
15.2 Operational malfunctions on KFGC
(CAN bus)
15.2.1 Pump malfunctions
The possible causes of malfunctions listed in
Chapter 11.1.8, "Malfunctions on KFG/KFGC
pump units," also apply for the KFGC CAN bus
version.
15.2.2 Faults detected by control unit
The comprehensive monitoring functions of
the LC-CAN 5000 control unit allow faults in
the operational process to be detected, regis-
tered and displayed.
Several faults, e.g., due to insuficient
ill level or the absence of a signal from
the piston detector, are only displayed
when system monitoring is active (see
Chapter 6.3.3.1, page 61).
