USE
This paragraph describes the fundamental operating
procedures. Detailed information and operating
procedures that involve optional connections or options
are supplied in the paragraph "USE" of the appendix
"Technical Information". Some procedures can be
executed with controller only when the accessory
"Hand held terminal" is available. Make all vacuum
manifold and electrical connections and refer to Turbo-
V pump instruction manual prior to operating the Turbo-
V controller.
!
To avoid injury to personnel and damage to the
equipment, if the pump is laying on a table make sure it
is steady. Never operate the Turbo-V pump if the pump
inlet is not connected to the system or blanked off.
The following figure shows the hand held terminal
control panel.
1.
Keyboard push-button for LOW SPEED mode
selection. It is active only when the front panel
operation has been selected. Pressed once, the pump
runs at about 2/3 of the nominal speed. To unselect
the mode, press the push-button again.
2.
Keyboard push-button for START, STOP, RESET
mode selection. It is active only when the front panel
operation has been selected. By pressing once the
starting phase begins; if pressed again it stops the
pump. If the pump has been stopped automatically by
a fault, this push-button must be pressed once to reset
the controller and a second time to restart the pump.
3.
Keyboard push-button to recall on the display the
cycle number, cycle time and pumplife.
4.
Keyboard push-button to recall on the display the
pump current, pump temperature, pump power and
rotational speed. It is always active regardless of the
