In order to ensure that the lubricant output
setting will be as excat as possible, first
the actual dimensions “S” of the max.
lubricant output must be ascertained as
follows. The measured difference from
the nominal value 29 must be considered
for all other settings values (e.g. ± 0.1).
Unsrew the adjusting spindle (1, Fig 10) from the pump
element body (3) until “S” is approx. 30 mm.
Srew counter nut (2) onto stop collar of the adjusting

Adjusting of small lubricant outputs
Before the pump element can be adjusted to a small lu-
bricant output, the dimension “S” for max lubrcant output
must be ascertained, and the difference from the nominal
value 29 must be tranferred to any desired settings be-
tween 25.5 ... 28,.5.
Dimension “S” must be adjusted to the desired value in
accordance with the delivery diagramm (Fig. 11).

Fig. 14 Pressure relief valve
Pressure Relief Valve
6001a02
IMPORTANT
Each pump element must be secured with
a pressure limiting valve.
The pressure relief valve
- limits the pressure build-up in the system
- opens at an overpressure of 250 or 350 bar depending
on the safety valve design.
If lubricant is leaking at the pressure relief valve, this indi-
cates that the system is malfunctioning.
6001a02
NOTE
Between a malfunction (blockage) and
the following fault indication (lubricant
leakage; monitoring intermittent LED
display on the control p.c.b. M00-M15)
there may be a longer time delay
The duration of the delay depends on the
type and length of the lines, the type of
lubricant, the ambient temperature and
other influences.
Despite existing fault monitoring devices a regular visual
and function control must be carried out on the lubrication
system.

Pressure relief valve with grease return (optional)
If the system is blocked, grease will leak from the pressure
relief valve. This grease quantity is returned to the reser-
voir.

Low-Level Control (optional)

1 - Guiding plate with round
solenoid 2 - Electromagnetic switch (at stirring paddle)
3 - Control cam
6001a02
NOTE
The above mentioned switching parts
must not be used with fluid grease. In this
case, use a float magnetic switch, see
below low-level control for oil.
6001a02
NOTE
The flashing signal starts only after the
solenoid has activated the electromag-
netic switch 6 times contact-free.
When the reservoir is filled
The stirring paddle rotates clockwise during the operating
time.
Due to the rotating motion of the stirring paddle in the
lubricant the pivoting guiding plate with the round solenoid,
item 11), is pressed backwards. The solenoid moves toward
the center of rotation of the stirring paddle. The electro-
magnetic switch item 21) cannot be activated.
Control cam item 31) guides the round solenoid with the
pivoting guiding plate automatically outwards, in the direc-
tion of the reservoir wall. After the lubricant has left the
control cam, it flows against the guiding plate, thus dis-
placing the solenoid again onto the center of rotation of the
stirring paddle.
1) All indications of positions refer to Fig. 17
When the reservoir is empty
During the rotating motion of the stirring paddle there is no
backpressure from the lubricant. The guiding plate with the
round solenoid no longer moves towards the center of ro-
tation of the stirring paddle. After control cam 3 has been
overtravelled, the solenoid remains in the outer position
and overruns electromagnetic switch 2. The solenoid ac-
tivates the electroma- gnetic switch contact-free, thus
triggering a low-level signal.
The flashing frequency in the case of printed circuit boards
236-13856-1 (F) and 236-13862-1 (V00-V03) and in the
case of pumps without control units depends on the motor
speed.
The flashing frequency in the case of printed circuit board
236-13870-1 (only M 00 - M 15) is:
0.5 second ”ON” - 0.5 second ”OFF”
M16 - M 23
The external relay drops out and the LED is extinguished once
the operating time has expired. The pump stops operating and
no longer restarts automatically.
Magnetic switch
The electromagnetic switch is activated contact-free and
with-out wear by the magnetic field of the magnetic fitted to the
stirring paddle.

NOTE
The life of the magnetic circuit breaker
strongly depends on the conditions under
which it is loaded. Since the data relative
to the maximum switching capacity refer
to strictly resistive loads, which cannot be
always guaranteed in practice, it is nec-

protection measures in the case of devi-
ating loads.
