8 Commissioning
WARNING
Danger while working in the danger zone of a machine!
Danger tolife, risk ofinjury orserious injury!
 Pay attention to potential danger sources and eliminate them before
commissioning the control block.
 Make sure that no one is in the danger zone of the machine.
 The emergency stop button for the machine must be within the
operator’sreach.
 Always observe the instructions of the machine manufacturer during
commissioning.
CAUTION
Commissioning animproperly installed product!
Mixing up the ports or cable connectors will cause unexpected functions and/
or irreparable damage to the control block and could endanger people and
equipment!
 Make sure that all the electrical connections and hydraulic ports are
connected orplugged correctly.
 Before thefunctional test, check whether thepiping specified inthe hydraulic
circuit diagram has been installed.
 Make sure that the cable connectors are correctly assigned tothe respective
electrical components.
 Only commission a completely installed product.
Risk of injury due to entrapped air!
In operation, air that is entrapped in the control block can cause components to
oscillate, strike the end stops hard and suffer damage. Unexpected movement of
actuators may cause serious injury.
 Before commissioning, it must be ensured that any air that is entrapped in the
control block is completely removed. This cantake place in all the switching
positions because of throughflow with a low hydraulic fluid flowq≤20% q

,
for example. In the case of control blocks without self-air bleeding, it may be
necessary to air bleed the cover using the air bleed screw.
 Always observe the parameters forthe air bleed inthe instruction manual
ofthe machine.
