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 controller is factory-set to operate via remote
signals with a Soft Start mode that allows the pump to
rump-up to Normal speed slowly. The minimum ramp-
up time is 75 seconds and the maximum is about 45
minutes. Differents default selection has been made as
per customer demans.
To modify the default values and to program the
controller, connect the hand-held terminal to the Turbo-
V controller.
NOTE
When the Turbo-V 70 pump is baked by a membrane
pump, the Soft Start mode should be deselected.

Startup

If the forepump and the vent device are not operated by
the controller, close the vent valve and switch on the
forepump.
Apply mains to the I/O connector. Voltage and
frequency output will be at the maximum level; then the
frequency will decrease to a value proportional to the
pump rotational (9 KRPM if the pump is completely
stopped) and then it will accelerate until the normal
condition has been reached.
The controller with the Soft Start mode allows the pump
to ramp-up to Normal speed slowly with a minimum
ramp-up time of 75 seconds and a maximum of about
45 minutes.If the Soft Start mode is deselected, the
ramp-up will be done within 75 seconds.

WARNING!

Monitor Mode

After the mains is applied to the I/O connector the
pump starts and the display shows in the following
figure.

square ( ).
•
As the ten steps are fully covered, the pump will
reach the Normal operation. If during the Soft Start
mode the current drawn by the pump exceed 1.4 A
the speed of the pump is decreased to maintain the
maximum power allowable (1.4 A).
If within each step of the Soft Start mode the
rotational speed of the pump do not rech the
planned value within 15 minutes the display shows:
F A U L T :
O V E R T I M E
where X = the step number from 0 to 9 indicating
the step number not passed.
When this message is displayed the pump is
stopped.

If the Soft Start mode has been deselected the display
will change and shows:

where:
1 2 = contrast inverted identifies the set point
condition:
− 1 is displayed when relay R1 is de-energized
and the related output is zero voltage.
− 2 is displayed when relay R2 is energized.
XX KRPM = indicates the actual theoretical
rotational speed of the pump as a function of the
controller output
75 KRPM).
After START command, frequency output will be at
the maximum level, then the frequency will
decrease to a value proportional to the pump
rotational speed (9 KRPM if the pump is completely
stopped).
The pump will accelerate to its normal rotational
speed and when this speed is reached, the display
will be as follows, even if any previous display
selection was made, and the normal condition has
been reached.
