Connection E - Controller to Power Connection

The power supply must be connected to L, N and E
faston connectors of the PCB.
The following figure shows the interconnection details.
Power Supply Interconnection

Connection F (P5) - Additional Fan Connection

An unswitched +24 Vdc fan connection is provided in
addition to that above mentioned. It is accessible via
P5 connector.

Connection G (P4) - Forepump Connection

A forepump connector output is available for controlling
a forepump.
The output line voltage is present when the controller is
in start condition.
Forepump Connector
!
The voltage available is the same as that used to
supply the controller, so keep attention to the voltage
required by the used forepump.
CAUTION!

OPTIONAL SERIAL PORT

Serial Port Installation

An optional RS 232/422/485 kit is available for both
models. To install it, proceed as follows:
Switch off the power
•
Attach the interface board connector to connector
•
P6 on thecontroller and then secure it in place using
screew A (3x6), which is not provvided..
Insert the flat cable and plug it into the socket P1
•
located on the Interface board.
Serial port connector installation

Serial Communication Port

Communication serial port connections and mini- mum
connection configuration are shown in the following
figures. The communication port mating connector is
supplied with the RS 232 PCB (AMP/Cannon or
equivalent 9-pin "D" type male connector). The external
cable (not supplied) between the host computer and
the controller doesn't require any crossed wires so that
signals are connected correctly.
For example, the Transmit data signal from controller
(pin 2) must be connected to the host computer's
Receive data line (pin 2) and vice versa. Consult the
host computer's instruction manual for its serial port
connections.
Varian cannot guarantee
regulations for radiated emissions unless all external
wiring is shielded, with the shield being terminated to
the metal shroud on the O-subconnector. The cable
should be secured to the connector with screws.
RS 232-422 Communication Descriptions
Communication format:
8 data bit
•
no parity
•
1 stop bit
•
The baud rate is programmable via front panel from
•
600 to 9600 baud. The controller is factory-set for
9600 baud operation.
