Controller-to-Pump Connection
A ten-meter long cable is to connect the controller to
the pump. The following figures show the controller
output connector configuration where pins:
•
B-G-E = 100 Vac 3-phase output to pump motor
stator
•
D = ground
Controller-to-pump connector
(applicable to model 969-9491 and 969-9591)
Connection P31 Turbo-V Pump Signals
A cable is provided to connect the controller to the
pump. If this cable is not connected on both sides, the
pump does not start. The signal cable is shown in the
following figure and has the following pin configuration:
P31 connector
Connection J21 Accessories and Options
Interconnections
The controller is provided with a power connector plug
J21. Ensure that the main circuit breaker is off, then
remove the plug and wire the pins (maximum wire size
18 AWG) as indicated below, to obtain the desired
capability as shown in the following figure.
Power socket output signals
Pin 1a - Ground
Pin 1b-3a, 3b-3a, 2b-2a -Output of 120 Vac
(independent of line voltage), 1 A total for vent device
and forepump relay coil.
Voltage is present after START push button is pressed
and remains present until an overload condition occurs
or power is removed from the turbo-pump.
Pin 4b-4a -Output mains voltage 3 A max. for heater
band. Voltage is present when the turbopump is
running and the heater band enable is selected YES.
