Motor (M) Valve (QM)
Releasing pressure:
The electric drive is not energized. The hydraulic uid is not
conveyed from the tank. If the 2/2-directional seated valve SP3
(QM) is open simultaneously, the hydraulic uid ows back into
the tank.
OFF OPEN
Maintaining pressure:
The electric drive is not energized. Closed seated valve (QM)
ensures that the pressure is maintained.
OFF CLOSED
3.4 Control
The product is preassembled and tested for installation in the higher-level machine. Hydraulic uid
is not included in the scope of delivery.
All of the necessary safety equipment, safety functions and the safety controller should be provided
by the machine manufacturer.
Ensure the following at the
machine.
■
Faults on the hydraulic power pack cannot trigger any hazard and can be safely rectied.
■
There is no hazard from failure of the electric power supply to the hydraulic power pack.
■
People cannot reach into the hazard zone of the hydraulic power pack.
■
People cannot burn themselves on the hot surfaces. After installing the hydraulic power pack in the
machine, label any hot surfaces that could pose a danger to people.
■
Choose a suitable hydraulic uid (mineral oil according to DIN 51524) and document this on the type
plate.
Operating modes and
vibration measurement
■
Operating modes & vibration measurement
■
The machine manufacturer must determine the operating modes for safe operation of the hydraulic
locking unit in the system.
Central control system and
software
■
A main switch and emergency stop function are integrated in the machine/higher-level control.
■
The pressure-limiting valve (P3B) is factory-set and safeguards the hydraulic system against excessive
pressure.
■
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.
