Start the pump with the turbo screen
When you push the START/STOP key, both the turbo and backing pumps start. The
display shows the turbo pump is accelerating by flashing the top left portion of the
percentage sign. When the turbo pump reaches normal speed (> 80% default) the
percentage sign stops flashing and remains steady.
If a turbo setpoint (TSP) has been set, only the backing pump starts when you push the
START/STOP key. The TSP LED flashes until the setpoint has been reached. Once the
setpoint has been reached the turbo pump starts and the TSP LED turns OFF. If no turbo
setpoint has been set, the TSP LED remains OFF.
Stop the pump with the turbo screen
1. To stop the pumps press the START/STOP key, the display will show "Stop" for three
seconds.
2. Press the ENTER key within that time to stop the pumps. If the ENTER key has not
been pressed, or the START/STOP or NEXT keys are pressed, the display shows the
turbo pump speed and the pumps remain running.
When the turbo pump is decelerating the bottom right portion of the percentage sign
flashes until the pump has completely stopped.
