3. Overview/functional description
3.3.1 Functional description of a general progressive system
A general progressive metering device sys-
tem consists of the following components:
o Pump unit with pump element and pres-
sure regulating valve
o Possibly function monitoring (piston
detector)
o Main lubricant line
o Main and possible secondary metering
device
o Branch and lubricant lines
When the pump motor is turned on, the
lubricant pump delivers lubricant from its
lubricant reservoir to the lubricant outlet.
The pump element attached to the out-
let delivers the lubricant further, into the
downstream main line. The lubricant flows
through the main line to the progressive
metering device, where it is distributed ac-
cording to the metered quantity required by
the lubrication point being supplied.
In progressive systems with a main meter-
ing device and secondary metering device,
the lubricant coming from the pump unit
is delivered to the main metering device.
The main metering device distributes the
lubricant to the secondary metering devices
according to their individual volume require-
ments. From there, the lubricant flows to
the lubrication points.
Depending on the pump design with
control unit, the following configuration,
monitoring, and connections options are
available:
o Interval time and pump cycle time can
be adjusted independently, including on
monitored systems
o Recording of remaining intervals and re-
maining lubrication times
o Data backup in case of voltage failure
o Non-volatile memory with PIN code
protection
o Connectivity for piston detectors to moni-
tor the metering device function
o Connectivity for an external fault indica-
tor light
o Connectivity for external fault pump
operation monitoring
o Connectivity for an external
pushbutton to trigger an intermediate
lubrication
o Internal fill level monitoring; the lubrica-
tion cycle stops and fault notification is
displayed if the level falls below minimum
o Fault memory
