Pump cycle time
The pump cycle time is the time during which
the pump delivers lubricant. When multiple
lubrication zones are used, one of the zone
valves is opened and then closed once the
pump cycle ends.
The duration of the pump cycle time is a time
value conigurable in hours, minutes and sec
-
onds. The pump cycle time for units with W1
ill level control can also be set in pulses, i.e.,
the number of agitator revolutions. The quan-
tity of lubricant to be delivered is thus largely
independent of ambient conditions.
It is also possible to limit the pump cycle time
based on the pulses (strokes) received from
the piston detector.
The pump unit switches off after the deined
number of pulses (strokes) is reached. The
pulses must be received within a deined pe
-
riod of time, otherwise the pump unit switches
to block operation.
Interval time
During an interval time, also called interval for
short, the pump is idle or, if multiple lubrica-
tion zones are used, the valve for the lubrica-
tion zone in question is closed.
The duration of the interval time can be
conigured.
In automatic mode, the interval time can be
determined in two different ways: by specify-
ing either a time value (interval timer) or a
number of pulses (interval counter) sent to the
control unit by the machine depending on how
long it has been running. This provides two
different means of control: timer mode and
counter mode.
In semi-automatic mode, the user sets the
interval between two lubrications.
When coniguring the lubrication scenario,
the interval time is a delay for consecutively
opening the valves of the individual lubrica-
tion zones after a lubrication cycle has been
started. This prevents all valves from opening
at the same time.
Block operation, pump delay time
and waiting time
On systems with piston detector monitoring,
there may be various non-critical reasons for
the set number of piston detector signals not
being received during the pump cycle time. In
this case, a second pump cycle time is started
after a certain delay.
This process can be repeated multiple times.
This process is also referred to as block opera-
tion, as the 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 set number of piston detector signals is
not reached during block operation, the control
unit switches off the affected lubrication zone
or the entire lubrication system and issues a
fault notiication.
The number of blocks to be cycled through can
be conigured.
