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 250 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 250 PCB pump
series. The controller drives (within ten steps) the
Turbo-V 250 PCB 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:

STORAGE
When transporting and storing the controllers, the
following
environmental
satisfied:
•
temperature: from -20 °C to + 70 °C
•
relative humidity: 0 - 95%
(without condensation).
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.
Controller Packing
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.
