The Expert in Lubrication Solutions
3.2.4 Function
Whenever external power is applied, the lubricator discharges a set amount of lubri-
cant in pre-determined intervals.
In the LC unit, a motor driven spindle pushes the lubricant out of the LC unit. The
piston will move and, depending on the counter pressure, will build up pressure in
the LC unit of up to
5 bar
(75 psi). The automatic pressure shut off will turn the
system OFF after several attempts when the pressure exceeds 5 bar.
With dip switch 3 and 4 of the 4-way code switch on the circuit board (marked “VOL”)
you can set the size of the LC unit. With dip switch 1 and 2 (marked “TIME”) you can
set the discharge amount for every 100 operating hours.
perma STAR CONTROL TIME divides the set discharge amount (= size of the LC
unit) into several small discharge cycles within the discharge period (please see the
following chart listing discharge amount per discharge cycle. Please also refer to
chapt. 7.3).
