4. Set the main switch to ON (rotate the shaft that engages the handle on the panel door clockwise
until it snaps into the ON position). Check for evidence of problems, such as the smell of over-
heating components or smoke. If such problems are indicated, set the main switch to OFF
immediately and call the factory before proceeding.
5. After the power is on, measure the voltage across the upper terminals on the contactor K1 (located
below the main circuit breaker). It should be the same as the measurements where the input
power connects to the main breaker. If there are any problems, check the wiring.
6. Apply power to the control by pressing the Power-On switch on the front panel. Check the high
voltage buss on the Vector Drive (pin 2 with respect to pin 3 on the terminal bus at the bottom of
the drive). It must be between 310 and 360 volts. 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. Next,
check the DC voltage displayed in the second page of the Diagnostic data on the CRT. It is labeled
DC BUS. Verify that the displayed voltage matches the voltage measured at pins 2 and 3 of the
Vector Drive +/- 7 VDC.
7. Turn off the power (rotate the shaft that engages the handle on the panel door counterclockwise
until it snaps into the OFF position). Also, set the main switch handle on the panel door to OFF.
(Both the handle and the switch must be set to OFF before the door can be closed). Close the
door, lock the latches, and turn the power back on.
8. Remove the key from the control cabinet and give it to the shop manager.
Transformer (t5) supplies 24 VAC to K1 contactor coil. this tansformer has a multi-tap wiring at the primary side
200/240V (360/400/480V version for high volt machines).
Note: Choose the correct tap according to the incoming power to the CNC machine.
