All logic control inputs and outputs are accessible at
logic connector J22. Ensure that the mains circuit
breaker is off, then remove the provided mating
connector P22 and make the connections with 26 AWG
(or smaller) wire to the pins as indicated below to
obtain the desired capability.
NOTE
With the remote STARTA..OW SPEED connection, the
front panel switches are not operative and viceversa

the Turbo pump starts and stops when
the contact is open.

This signal can be used to delay the

NOTE
Pin 13-5 must be shorted to allow the Turbo-V pump to
start if a vacuum pressure switch or an external contact
is not connected.

CONTROLLER TO PUMP CONNECTION

Before connecting the Turbo-V pump to the controller,
ensure correct grounding between pump and controller.
A five-meter long cable is to connect the controller to
the pump. The following figures show the controller
output connector configuration where pins:
•
A-F = pump temperature sensor
•
B-G-E = 90 Vac 3-phase output to pump motor
stator
•
C-D = Spare provision
