32/128 Product information
Bosch Rexroth AG, CytroBox, RE 51057-B/11.19
5.3.3 Monitoring systems
The following monitoring functions are provided:
The monitoring of the oil filter and of the optional return flow filter are active if the
drive controller is enabled and the minimum oil temperature (P-0-1389[29]) for the
debouncing time (P-0-1389[24]) has been reached.
This status is established with a cycle time of 200ms.
For the oil filter, the pressure differential between the filter pressure (P-0-1273) and
the system pressure (S-0-0813) is monitored. The monitoring is based on a cycle
time of 1ms.

In addition, the actual pressure value of the return flow filter (P-0-1283) is
monitored. The monitoring is based on a cycle time of 1ms.

The monitoring of the leakage flow is active if a measured value via an I/O link sensor
is present. The monitoring is based on a cycle time of 1ms.
