Inspect the controller for any shipping damage.
The Turbo-V 301 controller model 969-9437 is factory-
set for 220 Vac operation and model
969-9537 is factory-set for 120 Vac operation.
!
The Turbo-V controller is equipped with a 3-wire power
cord and plug (internationally approved) for user's
safety. Use this power cord and plug in conjunction with
a properly grounded power socket to avoid electrical
shock.
High voltage developed in the controller can cause
severe injury or death. Before servicing the unit,
disconnect the input power cable.
NOTE
The Turbo-V controller can be used as a bench unit or
as a rack module, but it must be positioned so that free
air can flow through the holes.
Line Voltage Change Over
If a change in line voltage operation is desired, proceed
as follows:
−
Disconnect the power cord from the controller
socket.
−
On power entry module, check back door for
voltage selector set.
−
Using a small screw driver, pull out the voltage
selector and fuses.
−
Select the operating voltage, then firmly insert the
voltage selector and fuses in place.
−
Check voltage selector window for correct set and
connect the power cord.
POWER INTERCONNECTIONS
Connection J7 - 120 Vac Connector
The 120 Vac, 1A maximum (independent of line
voltage) output voltage is present after START
pushbutton is pressed and will remain present until a
fault condition is displayed on the front panel display or
the turbopump is stopped.
To make connections, remove the plug and wire the
pins (maximum wire size 18 AWG, 1 mm
2
) as indicated
in the following figure to obtain the desired capability.
J7 Connector Output Power
CAUTION!
On the J7 outlet the output voltage is 120 Vac with the
maximum current of 1 A.
If more than one device is connected, be sure to draw
not more than 120 VA to avoid controller damage. Use
a relay coil with a maximum surge power of 65 VA.
NOTE
Forepump relay coil is an independent, user supplied
item.
