Installation; J3 Connector; J2 Connector; J4 Connector - Varian Turbo-V 81 PCB 24 Vdc Notice De Mode D'emploi

INSTALLATION

Inspect the controller for any shipping damage.
The controller is designed to be installed into a rack.
All the connections are fitted to J2, J3, J4 and J5
connectors.
Should the controller be connected to a host computer
via the-RS-232 interface, a suitable cable must be
prepared.
In the following paragraphs
input/output signals.
The PCB installed into the customer system must be
positioned so that cold air (forced or natural convection)
can flow through the PCB components.

J3 Connector

J3 – Power Connector
The signals of J3 connector are the following:
•
Pins 1/2 Power supply 24. Vdc (20 to 32 Vdc) (pin
2 positive).
•
Pins 4/3 Kl relay contacts. The relay switches
when the output frequency overrides the set
threshold (1117 Hz).
indicated also on pin 6 of J4 connector.

J2 Connector

J2 – Connector to pump
The signals of J2 connector are the following:
•
Pin 1 68 Vac 3-phase output to pump motor stator
(phase T).
•
Pin 2 68 Vac 3-phase output to. pump motor stator
(phase S).

NOTE
The threshold overriding is
•
Pin 3 68 Vac 3-phase output to pump motor stator
(phase R).
•
Pins 5/4 Pump temperature sensor.

J4 Connector

the
The signals of J4 connector are the following:
•
Pin 3 24V 60mA open collector Output failure.
When a fault condition is detected, the pump is
stopped and this output is ON.
•
Pin 5 24V 60mA open collector Output Low Speed
mode activated. When the Low Speed mode is
activated this output is ON.
•
Pin 6 24V 60mA open collector Output When the
output frequency is less than 1117 Hz, this output is
ON.
•
Pin 7 Analog output. A voltage from 0 to 10 Vdc
proportional to the supply current (from 0 to 2.5 A).
•
Pin 8 Analog output. A voltage from 0 to 10 Vdc
proportional to the output pump motor driving
frequency (from 0 to 1350 Hz).
•
Pin 11 Error reset command. Should an operation
fault be detected (Pin 3 of J4 is ON), the pump is
stopped. To reset the fault you must connect pin I I
to ground (pin 15 of J4) for at least I sec.
•
Pin 12 ON/OFF pump. To stop the pump you must
connect pin 12 to ground (pin 15 of J4); to start the
pump you must remove the contact between pin 12
and ground.
•
Pin 13 Low Speed mode activation.
contact between pin 13 and ground (pin 15 of J4)
closes, the turbo pump runs at low speed and when
the contact opens, the turbo pump reverts to high
speed mode.
When the Low Speed mode is activated pin 5 of J4
is ON.
The Low Speed frequency is 1100 Hz.
