2.6.3. First run of the power pack
Before the first run check:
•
The direction of the Pump, while run the power pack for max. 2seconds.
•
The cooling fan of the motor has to rotate in the same direction as the arrow on
the top of the motor cowling indicates.
•
In case of wrong rotational direction, the electrical phase in the connection box is
to be changed. This check is required after every disconnection from the power
source
•
Wiring matches with electrical and hydraulic diagrams
•
the electric motors (pump and cooler) are properly connected and have the
prescribed rotation
•
the hydraulic accumulator with nitrogen gas to the specified value
•
aux. elements work right (thermometer, level gauge, heater)
First run (Attention – working pressure on securing valve is set by producer in
accoring the hydraulic diagram):
•
In the short intervals activate an electric pump
•
check for leaks and noise
•
Bleed the hydraulic circuit
•
if possible, test the circuit function with minimum load
•
test the electrical equipment
•
during operation monitor measuring equipment, noise, height and temperature of
oil in the tank
•
During this time a careful bleeding off for the whole hydraulic system is necessary.
In case there is no bleeder port, the power pack will bleed itself after a while via
the air breather on the tank or the return line filter.
•
After multiple start-up.
2.6.4. Filling the reservoir with hydraulic oil
Oil regulations and recommendations of the manufacturer in the technical
documentation (appendix) are to be carefully observed. For standard power packs we
recommend the oiltype OH-HM32 (DIN 51524) of all known oil manufacturers.
Power packs have to be filled up with clean, pre-filtered oil! The purity of the hydraulic
fluid must correspond to the class 10 NAS 1638 (reachable with filter ß =75)!
Filling from container, such as barrels, backets, etc. is not recommended or permitted!
The maximum oil level will be shown on the upper marking at the dipstick or the sight
level glass. Overfilling has to be prevent. The maximum filling rate of 15 l/min shouldn´t
be exceed.
