Grizzly H3473 Static Phase Converter Owner Manual

 INSTALLATION INSTRUCTIONS
AUTOGEN CD-SERIES PHASE CONVERTERS
| Electric shock can injure or kill you. This equipment should be installed in accordance with local and National Electric Codes.

If you connect this converter at the load side of a motor starter it may chatter. While this will not harm anything, it will defeat
the design of the unit, which is to close the starting contactor before power is applied to the motor. Any CD or CD-SD or XCD
Series should be connected at the line side of the machine to be operated.
Notice |
This Autogen CD Series Static Phase Converter is equipped with an electronic starting relay. When power is applied to the |
Autogen, you will hear a contactor close with a snap. Not to worry—it can sit that way indefinitely. Power consumption is less |
that that of a Christmas tree lamp (2 watts). The contactor will also snap closed when the motor is turned off. No problem—it is
merely getting ready for the next start.
Warning: Disconnect power before servicing or connecting any equipment!

Refer to the wire size chart (on reverse) for information pertaining to the motor you wish to operate. Choose one of the
diagrams following to connect your converter. Single-phase power connects through L1 and L2. T3 is the generated phase.
Be sure all equipment is grounded and do not ground T3.
When you connect your equipment be sure that magnetic controls are operated on the Single-Phase lines (L1 & L2). T3
(Generated phase) will not properly operate these controls. If your 3-phase machine has magnetic controls, these operate
from two of the three machine input terminals. Leave off T3 and connect single phase, switching leads and trying the
controls until you find correct combination that makes the magnets work and the motor buzz. Turn off power immediately
when you find the right pair. Connect T3 to the remaining machine input.
Turn the power on to the converter. You should hear an audible click in the Autogen as the start contactor engages.
Turn the machine on. The red/amber start light on the Autogen should come on during motor starting only, and the motor
should be up to speed in approximately 3 seconds. If the motor does not attain operating speed within 5 seconds, or if
the red light stays on after the motor starts, shut power off immediately and review your installation. (Troubleshooting
Guide follows.) - i
If the machine runs backward, turn off all power and swap leads L1 & L2 from the converter to the machine. This will
reverse the motor rotation. |

converter “on” and converter “on”
Ll to L2 — 208-250v L1 to L2 — 208-250v

L2 to T3 — 0 (Voltage only with motor on) L2 to T3 — 200-275v
Line-to-Neutral voltages mean nothing on a 3-phase system and should be ignored.
Line currents on this device will balance with motor operated at approximately 70% of full-load.

Wire sizes are for copper conductors. Use one size larger if using aluminum wire. Since you are producing 3-wire power from a
2-wire supply, these guidelines should be strictly followed or poor motor performance will result. Wire size should be
increased for distances greater than 50ft.

Wire sizes for 230 volt operation. For 460 volt use wire for a motor 1/2 the size you are operating.

IF YOU HAVE TROUBLE:
Remember that the Autogen you are using was tested on a motor before shipment. There is about a 98% chance that converter
malfunction is a result of a problem in the installation or motor rather than the converter. First, re-read the instructions and re-
check your installation.
I. The converter must “click” when power is applied. “No click” means power is not reaching the converter.
2. The red/amber light on the converter is a indication of operation. If you heard the “click” but the light does not come on
when you attempt to start the motor, the converter may be too powerful for your motor, or the motor may be wired for a
higher operating voltage. The same is true if the light flashes on-off when the motor starts. A bright light at full motor speed
may mean the start contactor has stuck.
3. Ifthe red/amber light is on bright but the motor does not come up to speed, your load may be too great for this device, or the
machine may have a defective bearing. Try the motor with the drive belt removed.
4, if the red/amber iight cycles off-on while the motor runs at speed, the load is too greai for an Auiogen, or your singie-phase
supply wire or transformer is too small for the load. Check the L1-L2 voltage at the converter while the motor is running. If
below 210 volts you have a supply problem. If voltage is good (230-250), you may: :
Install a larger motor and Autogen, or use the idle motor method (see below);
On some machines such as air compressors, you may replace the motor (drive) pulley with a pulley 10%- 15%

This will affect machine speed only slightly and usually solves the
5. If the motor runs but the thermal protection trips: Set (adjustable) trip higher, or replace “heaters” with | or 2 sizes larger.
This is a common problem on air compressors.
6. If the controls refuse to work on your machine, or “chattering” sometimes occurs on machine starting, you probably have T3
powering a magnetic starter coil or control transformer; or the coil or control transformer may be connected for a higher
voltage.

IDLE MOTOR METHOD: —
The Autogen works better when another motor is run idle with one
or more load motors. The idle motor acts as an “electrical flywheel”
carrying the load along and preferably will be 1 or 2 sizes larger
than the load motor you are having trouble with. Using an idle
motor will also enable you to operate 3-phase transformer loads, DC
drives, etc. Connect as shown. = L2 &

For 3-phase welders, battery chargers, etc., use an idle motor of |HP |
for every 3 amps of machine load. (Ex: A 200 amp welder that
draws 22 amps takes a 7 1/2HP idle motor, since 22 divided by 3
equals about 7.5)
