In case of a fault, e.g. insufficient fill level, a fault
message is generated and the operational sequence
is stopped. The cause of the malfunction can be
shown on the control unit's screen. In addition, the
fault hours figure is stored and can also be
displayed.
3.5.5. Progressive distributor monitoring
The progressive distributor monitoring capabilities
differ on the KFAS and KFAS1-B series as follows:
KFAS
o Progressive distributor monitoring using one
cycle switch
o Number of edges for cycle switch is not
adjustable
With each piston stroke of the corresponding
progressive distributor, the cycle switches generate
a switching edge, which is registered by the control
unit and used to control the contact time. The
number of switching edges (stroke number)
required to limit the contact time can be set on the
control unit. Two switching edges are required for
one revolution of the progressive distributor.
3.5.6. Block mode
When progressive distributor monitoring is active,
the duration of the lubrication procedure
corresponds at least to the set contact time, though
the programmed number of switching edges for the
cycle switch(es) must also be attained. If the
required number of switching edges for the cycle
switch(es) is not attained during the contact time, an
additional contact time is started after a defined
delay. This process can be repeated up to three
times. This process is also referred to as block
operation, as the piston pump starts and stops
quickly several times.
Block operation is interrupted as soon as the set
number of piston detector signals has been received.
The length of an interval time following a successful
block operation is not changed. Operation continues
as normal. If the required number of switching
edges for the cycle switch(es) is not attained during
block operation, a fault message is issued.
3.5.7. Fill level monitoring
On units with fill level switch, the fill level is
monitored by the control unit. As soon as the fill
level of the lubricant reservoir falls below the
minimum, the control unit stops the operational
sequence of the centralized lubrication system and
issues a fault message.
If fill level monitoring is installed, it is always active.
3.5.8. Parameter memory
All essential system parameters are stored in the
control unit's non-volatile memory, ensuring that no
data is lost even in case of power failure or a
completely.
3.6. Piston pump units with
progressive distributor installed
Piston pump units of the KFA(S) series can
optionally be equipped with a progressive
distributor. The progressive distributor is mounted
at the base of the pump housing. The number of
lubricant connections on the mounted progressive
distributor is variable and must be specified when
ordering.
