Electrical power must be phased properly to avoid damage to your equipment. The Power Supply
Assembly PC board incorporates a "Phase Detect" circuit with neon indicators. When the orange neon is lit
(NE5), the phasing is incorrect. If the green neon is lit (NE6), the phasing is correct. If both neon indicators
are lit, you have a loose wire; check the connections. Adjust phasing by setting the source power to off and
then swapping L1 and L2 of the incoming power lines at the main circuit breaker.
Danger: ALL POWER TO CNC MUST BE TURNED OFF LOCKOUT-TAGOUT AT THE SOURCE PRIOR TO
ADJUSTING PHASING. ALWAYS DOUBLE CHECK THE INCOMING LINES WITH AN AC VOLTAGE DETECTOR.
Turn off the power and set the main circuit breaker to OFF. Close the door, lock the latches, and turn the
power back on.
Remove the key from the control cabinet and give it to the shop manager.

Activation
When the machine is properly placed and connected to both air and electrical power, it is ready for final
installation (removing shipping blocks, leveling, spindle sweep, etc.) and software activation. The HFO
service technician does this. Contact the local HFO to schedule the work.

Apply power to the control by pressing the
Power-On switch on the front panel.
Check the DC Voltage and AC Line Voltage
gauges in Diagnostics. The DC Voltage gauge
must read between 310 - 360V. The AC Line
Voltage must be between 90 and 105
percent. If the voltage is outside these limits,
turn off the power and recheck steps 2 and
3. If the voltage is still outside these limits,
call the factory.
