Ventilation of the lubrication system
· Ventilate the whole lubrication system on first start-up and after each lubricant change!
· Ventilation is done by operating the system in pressureless condition and with open system outlets!
· Operate the device until lubricant escapes from the pressure connection without air inclusions.

Functional description
8.1
Lubrication systems
The device can be used for the lubrication in progressive lubrication systems, multi-line lubrication systems or in mixed
lubrication systems. The lubrication systems are also controlled by the integrated control unit PICO-troniX1 or PICO-
tronic.
Up to two lubrication circuits, which are independent from each other, can be connected the device at installation into a
progressive lubrication system.
Up to 8 lube points can be supplied with lubricant when the device is used in a multi-line lubrication system.
Both systems can also be combined with the device (mixed lubrication system).
8.1.1 Progressive lubrication systems
Progressive lubrication systems are lubrication systems which can process lubricants up to NLGI cl. 2.
A progressive lubrication system mainly consist of a lubrication pump and one or several progressive distributors. The
lubrication pump supplies the lubricant into a main distributor. This distributor distributes the lubricant in the correct
relation to the secondary distributors, which redistribute the lubricant to the lube points.
If one lube point does not take any lubricant from the distributor, it blocks. Pressure builds up in the system by this. The
system pressure is limited to 290 bar by a pressure limiting valve at the pump element (see fig. 19, pos. 11 and pos. 12).
The system is thereby protected from being damaged by too high pressure.
8.1.2 Multi-line lubrication systems
Multi-line lubrication systems are lubrication system which can process lubricants up to NLGI cl. 2.
A multi-line lubrication system mainly consists of a lubrication pump and several lubrication lines which are connected
directly to the lube points. Each lube point requires its own pump element at the lubrication pump (see fig. 19, pos. 3 up to
pos. 10).
8.1.3 Mixed lubrication systems
A progressive lubrication system and a multi-line lubrication system can be connected the device at the same time; this
is called a mixed lubrication system.
One lubrication circuit with progressive distributors can each be connected the pump elements pos. 1 and pos. 2 (see
fig. 19). One lube point can each be connected the pump elements pos. 3 to pos. 10 (see fig. 19).
