Operation
Figure 9 - User interface panel
4.2.1 Start and stop
Use the buttons (Figure 9, items 3 and 12) to start and stop the pump. Note that the stop command does not isolate
the pump from the electrical supply.
4.2.2 Standby
Operation at reduced speed will further improve tip seal and bearing service life. Vacuum performance will be
reduced when operating at standby speed.
Press the Standby button to select standby mode. The pump will initially run at factory default standby speed (70%
of full speed). The speed can be adjusted using the increase and decrease standby speed buttons. The maximum
standby speed is 100% of the default run speed and the minimum standby speed is 67% of the default run speed. A
single short push will change the speed by 1% of the default run speed, holding the button will change the speed by
1%/sec. Once adjusted, the pump will return to this new user-defined speed each time standby speed is selected.
The Standby button must be pressed to return to normal run speed.
