6.2 Selection of the parameters t and C.
NOTE
The emptying time t can only be set on the lubricator when it is not controlled by an
external controller (Pu0).
Emptying time t for 125 cm³ cartridge (U12)
t (months) 1 3 6 10 12 15 20 24 30 36
Lubricating quantity per month [cm³] 125 41.6 20.8 12.5 10.4 8.3 6.3 5.2 4.2 3.5
Emptying time t for 250 cm³ cartridge (U25)
t (months) 1 3 6 10 12 15 20 24 30 36
Lubricating quantity per month [cm³] 250 83.3 41.6 25 20.8 16.7 12.5 10.4 8.3 6.9
Values for t are examples; values from 1 to 36 (24 V version) / 1- 24 (battery version) can be set.
Number of cycles C, strokes per cycle
C 1 2 3 4 5 6 7 8 9 10
Lubricating quantity per cycle [cm³] 0.15 0.30 0.45 0.60 0.75 0.90 1.05 1.20 1.35 1.50
The emptying time t specifies the period over which the entire quantity of lubricant is supplied per car-
tridge. Correspondingly, it also defines how much lubricant is supplied per month.
The number of cycles C indicates how many strokes take place per lubrication and thus how much
lubricant is supplied per lubrication.
The time between two lubrications (dwell time) can be determined with the following equation:
T
dwell
= t x 720 h x C / H
With t in hours and H as the total number of strokes per cartridge (830 with a 125 cm³ cartridge), the
dwell time for a lubricating quantity of 0.60 cm³ (C4) over six months is calculated below:
T
dwell
= 6 x 720 h x 4 / 830 = 20.9 h
The result of the calculation is a lubrication cycle of 21 hours. 0.60 cm³ of lubricant are supplied every
21 hours over a period of six months.
