The 120 Vac, 1 A maximum (independent of line
Voltage) output Voltage is present when the main
power switch is set to 1 position and after START push-
button is pressed and will remain present until a fault
condition is displayed on the front panel display or the
turbopump is stopped.
The connector J21 is a power output for vent device,
forepump relay coils.
To make connections, remove the plug and wire the
pins (maximum wire size 18 AWG, 1 mm²) as indicated
in the figure to obtain the desired capability.
NOTE
Forepump relay coil is an independent user supplied
item.

Serial port connector installation

Serial Communication Port J13

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 does not require 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.
