8.1.6 Switching on the drive motor of the pump
To prevent undefined states, the power supply of the valve electronics should be
switched on first, then the drive motor of the pump (see chapter 5.11 “Activation
sequence of electronics/hydraulics” on page 36).
Following this, you should check the following points (motor is still switched off!):
1.
No error messages are present and the controller enable is set.
2
.
The actual swivel angle value (SWA
act
) of the pump is in the order of +100 % ±3
% (mechanical limit stop)
In this state, the warning E2282, “Control deviation pump controller” can be
output, because the drive motor is still at rest. Later, when the motor is
running, this warning should no longer be issued. To suppress the warning
while the motor is at rest, you can enter a swivel angle command value of >95
%.
Note:
Table 15: Errors and their remedy/cause
Error
Remedy/cause
No voltage supply
available
Check voltage supply at the central plug of the electronics
Field bus does not work Check cabling
Check IP address
Fault in the pressure
measurement branch
Read out the actual pressure value (p
act
); it must be 0 bar. The
output signal of the pressure transducer must be compatible
with the type of the control electronics (current, voltage, zero
point).
Error in the swivel angle
measurement branch
Read out the actual swivel angle value (SWA
act
). In the case of
deviations from value +100 % ±3 %, check the cable connection
of the swivel angle sensor.
Further explanations regarding fault analyses can be found in chapter 15
“Troubleshooting” on page 81.
1.
Close all directional valves upstream of consumers.
2.
Open directional valve to the oil tank for pressureless circulation.
