Commissioning 63/78
RE 66170-B/2019-05-15, Control block SB24/34, Bosch Rexroth AG
▶
Only use hydraulic fluid in compliance with the data sheet:
– Permissible hydraulic fluid
– Hydraulic fluid temperature range
– Viscosity range
– Maximum admissible degree of contamination of hydraulic fluid
The control block/control block segments must be within a temperature range of
20 to 80 °C.
The temperature of the hydraulic fluid must be in a temperature range of
20 to 80 °C. The temperature difference between the control block/control block
segment and the hydraulic fluid must not exceed 20 °C.
8.2 Initial commissioning
For initial commissioning of the control block/control block segment, proceed
as follows:
1.
Reduce the first flow to a minimum to prevent a pressure surge.
2.
Slowly increase the flow.
3.
Maintain a flow of
q
Pump
≤ 20 l/min to the control block/control block segment.
4.
Apply air bleeding at the control block/control block segment, see chapter 8.3 on
page 64.
– Bosch Rexroth recommends separate air bleeding at the individual directional
valves.
– Also observe the information on air bleeding in the instruction manual of the
machine.
5.
Carry out a leak test.
Make sure that there is no hydraulic fluid leakage at the control block/control
block segment during operation. In case of hydraulic fluid leakage,
refer to Table 37 "Malfunction table" on page 74.
6.
Carry out a functional test.
The functional test must be carried out according to machine/system
manufacturer specifications.
7.
Check the pressure setting
Check the maximum pressure at the PRV of the connecting plate or central
connecting plate and at the EHR control valve. In case of malfunctions, refer
to chapter 14 "Troubleshooting" on page 73.
