3.3.6 Pressure Monitor

The total number of times of the double speed section error is
indicated.
The double-speed section error indicates that the pressure fails
to return to the reference level (previous pressure) even after
double-speed control (an increase of pump motor speed) was
effected to compensate for decreased pressure. Air bubbles in
the flow path may cause the error.
