7.4.9 Electrically connecting the axial piston unit
NOTICE
Short circuit in event of penetrating hydraulic fluid.
Fluid can penetrate the product and cause a short circuit.
▶
Do not install axial piston units with electric components (e.g. electric controls,
sensors) in a reservoir below the fluid level (inside-reservoir installation).
The machine/system manufacturer is responsible for the layout of the electric control.
Electrically controlled axial piston units must be connected in accordance with the
electrical circuit diagram for the machine/system.
For axial piston units with electrical control and/or mounted sensors, please comply
with the details given in data sheet 92003, e.g.:
•
Permissible voltage range
•
Permissible current
•
Correct pin assignment
•
Recommended electrical control units
Exact details on the connector, type of protection and matching mating connector
can also be found in data sheet 92003. The mating connector is not included in the
scope of delivery.
1.
Switch off power supply to the relevant system component.
2.
Electrically connect the axial piston unit (12 or 24 V). Before connecting, check
that the connector, including all seals, is intact.
If necessary, you can change the connector orientation by turning the solenoid. This
is dependent on the connector version.
To do this, proceed as follows:
1.
Loosen the mounting nut (
1
) of the solenoid. To do this, turn the mounting
nut (
1
) one turn counter-clockwise.
2.
Turn the solenoid body (
2
) to the desired position.
3.
Re-tighten the mounting nut. Tightening torque of the mounting nut: 5
+1
Nm.
7.5 Performing flushing cycle
In order to remove foreign particles from the system, Bosch Rexroth recommends a
flushing cycle for the entire system before the first commissioning. To avoid internal
contamination, the axial piston unit must not be included in the flushing cycle.
The flushing cycle must be performed with an additional flushing unit. Follow the
instructions of the flushing unit's manufacturer for the exact procedure during the
flushing cycle.
