Protection against
overpressure
Comfort version
The congurable 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.
Basic version
The congurable pressure-limiting valves are installed downstream of the check valves. They protect the
system against excessive pressure. Hydraulic uid ows back to the tank.
DAMAGE
Malfunction of the check valves due to leaking pressure-limiting valves (Basic version)
If actuated frequently, congurable pressure-limiting valves are no longer 100% tight, and thereby
disrupt the function of the check valves.
►
Avoid bottoming out the cylinder.
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.
