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
% (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
%.
