Operating Instructions
2.1EN-38016-C09
Return Line Connection
Fig. 6-1 Return Line Connection
T-P203Fp-020e08
The lubricant quantities which cannot be dispens ed by the
metering device must be returned to the pump via the re-
turn line connection.

Reservoir filled
The stirring paddle rotates
clockwise
during the lubricating
tim e.
The entry of the stirring paddle B (fig. 8-1) into the lubricant
presses the pivoted guiding plate with the round solenoid 1
inwards to orbit A.
The solenoid switch 2
cannot
be activated contact-free.
Control cam 3 guides the round solenoid with the pivoting
guiding plate automatically outwards, in the direction of the
reservoir wall. When leav ing the control cam, the lubricant
presses against the guiding plate and moves the solenoid
inwards again (B).

NOTE
The switch parts of the low-level control
(items 1 to 3) cannot be used with fluid
greases.

NOTE
The flashing signal * LL * starts as soon as
the solenoid has activated the solenoid
switch six times contact-free.
When passing the control cam 3 (fig. 8-2) the solenoid
remains in the outer orbit C and thereby passes the sole-
noid switch 2. The solenoid activ ates the solenoid switch
contact-free and so initiates a low-level indication.
When the stirring paddle rotates on the outer orbit C there
is no counterpressure by lubricant.
The guiding plate with the round solenoid 1 remains un-
entered (D).
