Connection J10
Controller-to-Pump Connection
A five-meter long cable is provided to connect the
controller to the pump. The following figures show the
controller output connector configuration where pins:
•
A-F = upper bearing sensor
•
B-C-D = 120 Vac 3-phase output to pump motor
stator
•
E = ground
•
A-G =lower bearing sensor
•
J-H =speed sensor
Controller-to-pump connector
(applicable to model 969-9448 and 969-9449)
Connection J11
Purge Flow Meter Connector
J11 connectors
PIN
DESCRIPTION
1-3
Flow meter power supply: 12 Vdc, 10 mA,
(pin 1 negative - pin 3 positive).
5-6
Analog signal with a voltage value
proportional to the flow.
Between 0 and 3 V it is linearly proportional
to between 0 and 100 sccm (pin 6
negative, pin 5 positive).
Connection J12
Heater Jacket Connector
J12 connectors
•
A-B
heater jacket temperature sensor
•
C-D
Main voltage output
(500 W maximum power)
•
E
Ground
(Earth)
!
The output voltage available at pins C and D for the
“Heater Jacket” supply has the same value as the
Mains Voltage applied to the controller.
OPTIONAL SERIAL PORT
NOTE
The Controller can be read when set in the
Front/Remote mode, (read window only enabled), while
it can be written to and read when set in the Serial
mode (write window enabled).
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 and disconnect the power
cord.
•
Unscrew the cover screws and remove the cover.
•
On rear panel, remove the connector cover, and
then secure connector
J13
to the frame using the
turrets provided.
•
On rear panel, remove the fixing turrets of
connectors
B
and
C
and then remove the controller.
•
Attach the interface board connector to connector
P6 on the controller and then secure it in place
using screw
A
(3x6), which is not provided.
•
Insert the flat cable through the rear panel and plug
it into the socket
P1
located on the Interface board.
•
Restore the main board into its original position.
•
Install and tighten the connector screws and turrets.
