Servo-hydraulic actuator
General
Bosch Rexroth AG RE62270-B, 01.21
8 Commissioning
8.1 General
WARNING
Working in the danger zone! Serious injury due to
improper working.
−
Pay attention to potential sources of danger and
remove them before starting up the servo-hydraulic
actuator.
−
Nobody may stay in the danger zone of the servo-
hydraulic actuator.
−
Do not reach into the range of the cylinder unit.
−
Electrical commissioning must be carried out or
attended by a skilled electrician.
WARNING
Uncontrolled system behavior! Electrical connections
which are not connected may cause malfunctions that
could lead to injuries.
−
Commission the servo-hydraulic actuator only when it
is completely installed.
NOTICE
Condensed water in electrical components! Risk of
short-circuit!
−
Let the electrical components acclimatize themselves
for several hours, since otherwise, condensed water
may cause problems.
Filling the "Split" variant with hydraulic fluid
The “Split” variant is shipped without hydraulic fluid fill. Bosch Rexroth has to
fill the servo-hydraulic actuator with hydraulic fluid. In this respect, contact
Bosch Rexroth Service, see

Chapter 16.1 “Service and support” on page 77.
The individual partial steps for commissioning are:
1.
Inspection of the mechanical and electrical installation and cabling work.
🡆
Visually inspect the servo-hydraulic actuator as well as the connected
operating equipment in the control cabinet for obvious visible defects.
🡆
Eliminate any defects found.
🡆
Check whether guards against direct touching of active parts are avail-
able, and that the protective guards are not faulty in the case of indi-
rect touching. Check the cross-section, routing, connection and the
marking of protective, earthing and equipotential bonding conductors.
🡆
Inspect the interface activation on the servo-hydraulic actuator side
and on the side of the customer system.
🡆
Testing and measuring of electrical components is to ensure that all
limit values or requirements (as given in the currently valid regulations)
are complied with. Measurements may only be taken using suitable test
equipment.
🡆
Measuring and test devices have to meet the requirements of stand-
ards, e.g. VDE 0411, 0413, 0403, 0404, and have to be listed in the test
report. Only calibrated measuring and test devices may be used.
2. Measurement / quality control of the supply voltages
3. Inspection of emergency stop equipment, insulation monitoring, protec-
tive guards as well as signaling and display devices.
4. Controlled commissioning of the servo-hydraulic actuator by progressively
switching on or activating switching circuits in the control cabinet.
