Fuse Holder And Voltage Changer Assembly; Input/Output Interconnections; Input Signals; Output Signals - Varian MicroVac 929-0200 Notice De Mode D'emploi

FUSE HOLDER AND VOLTAGE CHANGER
ASSEMBLY
If a change in line voltage operation is desired, proceed
as follows:
•
Unplug the power cord from the controller rear
panel socket.
•
On the power entry module (rear panel), check back
door for voltage selector set.
•
Using a small screwdriver, pull out the voltage
selector and fuses by levering in position A.
•
Replace the fuse.
Use only T-type fuses of the following
characteristics:
- 100/120 Vac 1 A
- 220/240 Vac 1 A

•
Check voltage selector window for correct set and
connect the power cord.

Input/Output Interconnections

All input/output signals are accessible at J001
accessory connector.
With the provided P001 mating connector make the
connections with AWG 24 (0.24 mm 2 ) - or smaller wire
- to the pins indicated in following figure, to obtain the
desired capability.

Input Signals

Pin 3-7 Remote high voltage ON/OFF or high voltage
Pin 3-7 must be shorted to allow the high voltage
output if no remote interlock contact is connected.

Output Signals

The front panel REC.OUT connector is a duplicate of
this signal on a BNC connector.

TECHNICAL INFORMATION
interlock; requires a permanent closed pin
contact.
NOTE
DESCRIPTION
Current recorder output (pin 2 signal out, pin
6 ground). The output voltage
+10 Vdc is proportional to the pump current 0
to 1 mA (e.g. 10 Vdc correspond to 1 mA).
The resolution is 10 mV minimum.
Voltage recorder output (pin 4 signal out, pin
8 ground). The output voltage 0 to 3 V is
proportional to the controller high voltage
output 0 to 3 kV (e.g. 1 V corresponds to 1
kV in linear mode).
High voltage indication contact. This pure
contact (which carries 1 A at 250 Vac and 0.2
A at 30 Vdc) is open when the high voltage is
off and closes when the high voltage in on.
