Starting The Pump - Varian Turbo-V 1000 ICE Manual De Instrucciones

Starting the Pump

If the forepump and vent device are not operated by the
controller, close the vent valve and switch on the
forepump.
Before starting the pump the cooling mode must be
selected.
With the FRONT panel operation selected, the
REMOTE and RS 232/422/485
inoperative; conversely, the CYCLE NUMBER and
PUMP CURRENT push-buttons are always active,
even when the operating mode selected is REMOTE or
RS 232/422/485.

Where the sign minus (-) become a square ( ) when the
pump finish the ramp-up step. The active step is indicated
by a flashing square ( ).
As the ten steps are fully covered, the pump will reach the
Normal operation. If during the Soft Start mode the power
drawn by the pump exceed 200 W the speed of the pump
is decreased to maintain the maximum power allowable
(200 W).

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

2 is displayed when relay S2 is energized and the
related output is 24V.
XX KRPM = indicates the actual theoretical rotational
speed of the pump as a function of the controller output
frequency (range 3 to 38 KRPM).
HJ = displayed only when the heater jacket is
active.
HS/HL = indicates that the pump is
working in the High speed or
Low speed mode.
After START command, frequency

value proportional to the pump rotational speed (about 3
KRPM if the pump is completely stopped).
The pump will accelerate to its normal rotational speed.
•
During acceleration of the pump or during any
operating condition, it is always possible to select the
other parameters to be displayed pressing the PUMP
CURRENT or the CYCLE NUMBER pushbuttons.
•
After the run up time and when the normal rotational
speed is reached, the display will be as follows, even
if any previous display selection was made, and the
normal condition has been reached.
