At switch-on, the gradient pump has recognized a new pump configuration.
The gradient pump is assigned its configuration at the factory. If the gradient
valve is disconnected, and the gradient pump is rebooted, the error message is
generated. However, the pump will function as an isocratic pump in this
configuration. The error message reappears after each switch-on.

When the pump restarts, the metering drive moves forward to the mechanical
end stop. Normally, the end stop is reached within 20 s, indicated by an
increase in motor current. If the end point is not found within 20 s, the error
