The control p.c.b. controls the sequence of the pause and
operating times of the 223 and 233 centralized lubrication
pumps as a function of the vehicle or machine working
hours t
B
(see fig. 20).
The sequence of the pause and operating times is acti-
vated when the machine contact or driving switch is
switched on, i.e. the centralized lubrication pump is ready
for operation.
A lubrication cycle consists of one pause time and one
operating time. Once the pause time has elapsed, the op-
erating time starts to run. This lubrication cycle is re-
peated permanently after the machine or vehicle has been
put into operation.
During the operating time the pump element dispenses
the lubricant to the lubrication points via progressive me-
tering devices.
