Before Initial Commissioning - Bosch rexroth M1-16 Series Instruction Manual

Commissioning | Control blocks for mobile applications
8�1 Before initial commissioning
▶ Ensure that the machine interfaces as well as the installation conditions
guarantee safe operation of the Rexroth control block. If in doubt, please
contact Bosch Rexroth.
▶ Using the instruction manual for the machine in which the Rexroth control
block is to be installed, visually check whether commissioning of the hydraulic
system can cause uncontrolled hazardous movements. Also observe the hazard
analysis/risk assessment of the machine.
▶ Take appropriate precautions for anticipated hazards e.g. make sure that the
cylinder piston rod can extend without any danger.
▶ Secure a load that is to be lifted with a lifting device / load handling
attachment.
▶ Check whether it is possible to use the machine's electric control to switch the
control block solenoids manually during commissioning. If it is only possible
to carry out manual switching under difficult conditions or if it is completely
impossible, you should prepare an external control to carry out the internal
functional test of the hydraulic system.
▶ Work out a sequence program for the commissioning and archive this in the
technical documentation as an annex to the instruction manual.
▶ Divide the functional circuit diagram into partial circuits which can be
commissioned in stages.
▶ Read the functional circuit diagram and clarify any ambiguous statements or
representations.
▶ Specify the switching position in which the directional valves are to be switched
or how the directional valves are to be set.
▶ Attach the necessary mandatory, prohibition and information signs and check
whether the meaning of these signs is explained in the instruction manual.
▶ Proceed with commissioning in the following order:
– Pump circuit
– Parts of the control: For example, pressure cut-off and switching,
free circulation, pressure reduction, etc.
▶ Make sure that all connection pipes and hoses are connected or that the
connections are plugged with threaded plugs.
▶ Make sure that the union nuts on the pipe fittings and flanges are tightened to
the correct standards.
▶ Set the pressure valves, flow control valves, pump controller, signal sensors,
pressure switches, position switches and thermostats to the switching positions
and setting values in the sequence program.
