Pump Connection; Interlock - Varian 929-0200 Bedienungshandbuch

12 Vdc

Pump Connection

The pump is connected to the controller rear panel via
the high voltage connector by a coaxial high voltage
cable assembly.
!
High voltage can cause severe injury or death. Before
installing or removing the connector:
•
Turn the power off.
•
When connecting the cable to 2 l/s pumps, or
larger, be sure that the ground spring is in place on
the high voltage connection of the pump.
•
Install the pump connector and secure it with
screws.
•
Plug the controller connector.

Interlock

The interlock is a safety device designed by Varian to
prevent serious damages to the operator due to high
voltage on the pump power connector.
Therefore, two serial electrically connected interlocks
are planned; both of them should be closed, so that the
pump can activate.
•
H.V. Cable Interlock consists of a Jack (A)
grounded through a cable connected to the metal
frame.
•
Remote ON/OFF Interlock consists of a P001
connector (included) whose 3 and 7 pins are short-
circuited (please refer to the previous figure).
In order to activate the pump, you should:
1. Plug Jack (A) into plug (B).
2. Plug P001 connector into J001 connector.
3. Place the main switch to ON.
