USE

General

Make all vacuum manifold and electrical connections and
refer to Turbo-V pump instruction manual before 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 input signal P1 connector should be left in position
including the shipping links if no external connections are
made. The forepump and the Turbo-V pump can be
switched on at the same time.
When the Turbo-V550 pump is baked by a membrane
pump, the Soft Start mode should be deselected.
The following instructions are applicable to Turbo-V
550 PCB Controller only when the optional "hand held
terminal" is installed.

Startup

•
Apply the mains to the controller.
•
The display lights, and shows:
R E A D Y
S O F T
The controller with the Soft Start mode allows the
pump to ramp-up to Normal speed slowly with a
minimum ramp-up time of 80 minutes and a
maximum of about 105 minutes.
The Soft Start mode is always operative as default
mode. If it is necessary to deselect this mode refer
to the following paragraph.
If the Soft Start mode is deselected, the ramp-up
will be done within 360 seconds and the display
changes as follows:
P U M P R E A D Y
S T A R T
•
Press the CURRENT pushbutton and the display
shows (e.g.):
P = X X X W
X X
where:
•
P = is the DC power drawn by the pump (range 0 to
999 Watt)
•
KRPM = is the theoretical rotational speed of the
pump as a function of the controller output frequency
(range 3 to 42 KRPM)
•
°C = is the temperature of the outer ring of the
upper bearing (range 00 to 99°C)
•
X = during operation a selected set point condition
(1 or 2 contrast inverted) appears when the
programmed threshold speed value is not reached.
