Activating The Power Supply; Bleeding The Entire Hydraulic System Of The Machine; Commissioning - Bosch Rexroth CytroPac Operating Instructions Manual

8.1.3 Activating the power supply

For activation, proceed in the following order:
1. Establish 24 VDC supply via enable interface.
2. Switch on feed-in/voltage supply.
3. Activate 24 VDC enable interface.
The plug-in connection of the feed-in/voltage supply (12X1) must never be
operated under load.
The power unit must be activated and deactivated by means of a respective
switching device of the superior machine control system (mains contactor, circuit
breaker).
For further information, refer to chapter 7.5 "Electrical interface assignment",
chapter 7.6 "Electrical interface connection" and the operating instructions of the
machine/system manufacturer.

8.1.4 Bleeding the entire hydraulic system of the machine

For further information, refer to the operating instructions of the machine/system
manufacturer.
▶ Bleed the hydraulic system at the highest point of the hydraulic components.

8.1.5 Commissioning

Activation of machine functions by means of commissioning!
Danger to life, risk of injury!
▶ Before commissioning of the hydraulic power unit, make sure that all electrical,
mechanical and hydraulic connections are properly installed and connected as
described in the superior instructions of the machine/system manufacturer.
▶ Make sure that the safeguards are activated.
Proceed as follows unless superior commissioning instructions must be observed on
machine level.
For commissioning of the hydraulic power unit, proceed as follows:
▶ Flush the hydraulic system as described in chapter 8.1.6.
▶ Operate the directional valves and extend and retract the actuators several times.
▶ Repeat the bleeding process.
Bleeding is ensured if no foaming of hydraulic fluid in the oil tank, no jerky
motions at the actuator and no irregular noise occur.
