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
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).

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

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.
