GENERAL INFORMATION
This equipment is destined for use by professionals. The
user should read this instruction manual and any other
additional information supplied by Varian before operating
the equipment. Varian will not be held responsible for any
events occurring due to non-compliance, even partial, with
these instructions, improper use by untrained persons,
non-authorised interference with the equipment or any
action contrary to that provided for by specific national
standards. The Turbo-V 550 PCB controller is a
microprocessor-controlled, solid-state, frequency converter
with self-diagnostic and self-protection features.
It incorporates all the facilities required for the automatic
operation of the Turbo-V 550 pump series. The controller
drives (within ten steps) the Turbo-V 550 pump during the
starting phase by controlling the voltage and current
respect to the speed reached by the pump.
Remote start/stop, pump status signals, forepump
start/stop, interlock control (for pressure switch, water flow
switch, etc.) capability, are provided via auxiliary
connectors. The controller needs to be powered by an
external transformer (not supplied with the PCB).
An hand held terminal is available as an option to control
and display the controller operation. The following
paragraphs contain all the information necessary to
guarantee the safety of the operator when using the
equipment. Detailed information is supplied in the
appendix "Technical Information".
This manual uses the following standard protocol:
!
The warning messages are for attracting the attention of
the operator to a particular procedure or practice which, if
not followed correctly, could lead to serious injury.
The caution messages are displayed before procedures
which, if not followed, could cause damage to the
equipment.
The notes contain important information taken from the
text.
STORAGE
When transporting and storing the controllers, the
following
environmental
satisfied:
•
temperature: from -20 °C to + 70 °C
•
relative humidity: 0 - 95%
(without conden-sation)

PREPARATION FOR INSTALLATION
The controller is supplied in a special protective packing. If
this shows signs of damage which may have occurred
during transport, contact your local sales office.
When unpacking the controller, ensure that it is not
dropped or subjected to any form of impact.
Do not dispose of the packing materials in an unauthorized
manner. The material is 100% recyclable and complies
with EEC Directive 85/399.
Before installing the controller you must prepare some
interconnection cables, i.e. the power interconnections, the
logic interconnections and the pump connections. The
following pictures show the interconnections between
pump and controller and between controller and power
transformer.
Detailed
information
transformer chatacteristics (available as an option) are
supplied in the appendix "Technical Information".
INSTALLATION
Voltages between controller and power transformer and
transformer and mains are dangerous in case of contact.
Protect adequately the controller and the transformer installed
into the customer system from accidental contacts.
High voltage developed in the controller can cause severe
injury or death. Before servicing the unit, disconnect the input
power cable.
High temperature developed in the controller can cause
severe injury.
Protect adequately the controller from accidental contacts.
