OPERATION
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 controller operates completely automatically after
the remote start command is given.
Switching on/off the Pump
To switch on the pump it is necessary to short circuit pin
1 and pins 5-6 (ground) of the 9 pin “D” type connector.
To switch off the pump it is necessary to remove the
short circuit between pins 1 and 5-6.
Analog output: 0 to 10 Vdc proportional to speed (0
to 10 V
≡
0 to 100% speed).
This output is active also during the
pump “slow down” phase after a Stop
command.
Low Speed Activation/Deactivation
To activate the Low Speed status it is necessary to
connect pin 9 of the 9-pin connector to pin 5-6 (ground)
of the 9-pin “D” type connector.
To deactivate the Low Speed status it is necessary to
disconnect pin 9 from pin 15 (ground) of the same
connector.
The low speed frequency is equal to 622 Hz.
