Operation5; Switching On/Off The Pump; Low Speed Activation/Deactivation; Error Reset - Varian Turbo-V 81 PCB 24 Vdc Bedienungshandbuch

OPERATION
Make all vacuum manifold and electrical connections
and refer to Turbo-V pump instruction manual prior to
operating the Turbo-V controller.
WARNING
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 unless the pump inlet
is 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 is necessary to remove the
connection between pin 12 of J4 connector and pin 15
(ground) of the same connector.
To switch off the pump is necessary to connect pin 12
of J4 connector to pin I5 (ground) of the same
connector.

Low Speed Activation/Deactivation

To activate the Low Speed status it is necessary to
connect pin 13 of J4 connector to pin 15 (ground) of the
same connector.
To deactivate the Low Speed status it is necessary to
disconnect pin 13 of J4 connector from pin 15 (ground)
of the same connector.
The low speed status is available on pin 5 of the same
connector.
The low speed frequency is equal to 1100 Hz.

Error reset

If the controller identifies an error, the pump is switched
off. After the error cause has been removed, the pump
does not automatically run up. It is necessary to reset
the error status: this is performed connecting pin 11 of
J4 connector to pin 15 (ground) of the same connector
for at least I second.

MAINTENANCE

Replacement controllers are available on an advance
exchange basis
information is provided to aid the operator in
determining malfunctions and corrective steps to be
taken.
Voltages developed in the unit are dangerous and may
be fatal. Service must be performed by authorized

Error Messages

For a certain type of failure, the controller will self-
diagnose the error and the following messages will be
displayed.
The controller signals the error occurred by means of a
diagnostic LED located on the board, and on the RS
232 port.
The LED blinks in a coded mode:
it flashes a number of time equal to the error
code (see the following table) and then stays off,
and so on.
