22/128 Product information
Bosch Rexroth AG, CytroBox, RE 51057-B/11.19
Usually, the following sensors, on which the basic functions of the CytroBox are
based, are built into the system:
• Pressure sensor for pressure control
• Filling level sensor in the tank
• Oil temperature sensor in the tank
• Pressure sensors for the identification of filter contamination
Optionally the system can be extended by the following sensors and thus also by
functions:
• Flow sensor in the drain line of the pump for leakage flow monitoring
• Temperature sensor in the drain line of the pump for leakage oil monitoring
• Sensor for the identification of the water content in the tank for the drainage
function
• Sensor for the identification of the dissolved air inclusion in the tank for the
degassing function
• Particle sensor for the identification of the contamination in the hydraulic fluid
• Leakage sensor in the drip pan
Current data and limit values can be read via the Multi-Ethernet interface, e.g.Sercos
or PROFINET, and forwarded to the superior machine control. This ensures reading of
all parameters required for condition monitoring / online diagnosis.
The operating condition of the hydraulic power unit is indicated on the integrated
LED status display as well as on the display of the drive controller.
Possible status messages are:
• Ab = drive is ready
• AF = drive in closed-loop control
• AU = drive in operation under control
A description of the operating unit integrated in the control section of the drive
controller and of possible operating states of the hydraulic power unit are
provided in chapter 5.3.1 "Drive controller".
Optionally, the following components are available:
• Hydraulic control, type IH20
• Accumulator station
• Customer-specific hydraulic control
