6.4 Power supply and switch-on
Important! Be careful to compare the data of the local voltage supply with
that given under "Technical data".
Important! Lay the power supply cable such that it cannot be torn off inadver-
tently.
Important! Work on electric facilities may only be performed by skilled electri-
cians in conformity with DIN VDE 1000-10.
Connect the unit to the voltage supply and control.
Check the electric connections for correct installation prior to commissioning.
Caution!
Work on electric facilities implies danger to life!
The swash plate needs about 10 seconds for one rota-
tion. The resulting electrical signal follows the pattern
t
on
= 1 sec - t
off
= 9 sec.
This means that an external control can also use this
signal for an emergency shutdown in case one or more
lubricant lines are blocked.
WOERNER recommends programming the external
control as follows: If, with the unit switched on, no new
signal is transmitted at the latest 12 ... 14 seconds af-
ter the last signal of the function control, the unit
should be disconnected from the power supply.
This helps to prevent damage to the unit as a result of
an overload caused by a closed lubricant line.
6.5 Commissioning
The unit‘s functionality has been checked in the factory. Hence, it is ready for operation and
can be connected to a local voltage supply.
Important!
Note the safety instructions contained in the "Power supply and
switch-on" section.
First fill lubricant and then start the pump unit, in every case
(Minimum filling level, see chapter 7.2).
If the installation position is unfavourable, lubricant must escape from all open outlets
after a maximum of 30 minutes of continuous operation.
