PLC
unit
Programmable Logic Controller composed of analog input chan
-
nels,
digital output channels and computing capabilities to control the
advance and retract operation of hydraulic cylinders within specific
parameters of accuracy and repeatability.
Pressure mode
Operational mode in which the PLC unit controls the pressure ap
-
plied to each hydraulic circuit against a maximum pressure value.
There is NO control of the actual movement of the
load in this mode.
Pressure sensor
Device to measure the oil-pressure within the hydraulic circuit, one
per hydraulic circuit (motion point).
Pump
unit
Assembly of a hydraulic pump mounted on a reservoir with valves
and pressure sensors.
Sensor cable
Shielded cable between the Displacement sensor and the PLC unit
as
carrier for the analog signal generated by the Displacement sensor.
Target
Total movement of the load that shall be achieved simultaneously at
all
lifting points under the control of the PLC unit.
