When Setting DSW-B No.1 to ON before Powering On

1) Set dip switch 1 of DSW-B to the ON position.
2) Switch "ON" the breaker on the rear panel.
After the STP pump completes the self test, the LCD displays the current rated speed in
"RATING: ***00rpm". The rated speed displayed here is the previously set rated speed
(or initial rated speed 48,000 rpm).
3) Press the "SELECT" switch three times to display "SET= ***00rpm", which indicates the
rated speed setting mode.
4) Turning the VR1 volume on the top panel changes the value "***00rpm" on the rated
speed setting display "SET= ***00rpm".
Turn the VR1 volume clockwise to increase the rated speed, or counterclockwise to
decrease the rated speed, until the required rated speed is displayed.
Note that the rated speed is not yet determined in this state.
5) To determine the rated speed displayed in "SET= ***00rpm", press the "START" switch.
Note that the rated speed is not determined if the "START" switch is pressed when the
LCD message is other than "SET= ***00rpm".
6) Press the "SELECT" switch once, and the LCD displays the set value of rated speed in
"RATING: ***00rpm". Make sure the required rated speed is displayed.
If the required rated speed is not displayed or the rated speed is to be changed again,
press the "SELECT" switch to display "SET= ***00rpm" again. Then, perform steps 4)
and 5) again to set the rated speed.
7) Perform STP pump rotation operation to start the STP pump. The STP pump accelerates
up to the rated speed.
