DAMAGE
Damage to the environment or property due to leaking hydraulic uid
If the screw is unscrewed too far, it may jump out due to the system pressure and hydraulic uid
may leak.
2. Closing the emergency manual valve: Tighten the screw with a torque of 3.0 + 0.5 Nm.
Protection against
overpressure
The congurable pressure-limiting valves are installed upstream of the check valves. Two additional
pressure-limiting valves with a higher opening pressure located downstream of the check valves protect
the system against excessive pressure. Hydraulic uid ows back to the tank.
3.3 Control
All of the necessary safety equipment, safety functions and the safety controller should be provided
by the machine manufacturer.
■
The motor’s duty cycle should be monitored by the device control. An increase in the duty cycle is an
indicator of abnormal internal leakage.
