First-Time Operation - Advanced Energy MDX II User Manual

FIRST-TIME OPERATION

This procedure assumes that a control panel has operational control (local control mode).
1. Ensure that the necessary external inputs are supplied (refer to signal descriptions
beginning on page 9-7) or that the "cheater plug" is installed on the User port connector
on the rear of the MDXII unit (see Figure 9-6 on page 9-5).
2. Connect the output connector (see details on page 4-10).
3. Turn on the circuit breaker at the rear of the unit. The output display screen will appear on
the display and the following LEDs will light:
– STOP
– One of the control modes (host, local, or analog)
– One of the methods of regulation (power, voltage, or current).
4. If the control panel does not have control, select the local control mode by pressing the
LOCAL switch.
5. Select a method of output regulation by pressing the POWER, VOLTAGE, or
CURRENT switch.
6. Set an output level (see page 5-3): At the output display screen, turn the MODIFY knob
to select an output setpoint.
DANGER:
Step 7 on page 5-27 will result in high voltage levels at the output connector. Take
appropriate steps to prevent electrical shock.
7. Press the START switch. The START LED flashes for about 3 s as the internal circuitry
is being initialized, then the main contactor closes. The output should reach the
programmed setpoint level in about 600 ms (50ms in units with fast ramp/run).
8. Press the STOP switch any time to turn off output.
WARNING:
You must give the power supply the OFF command before turning off the input line
power or the rear circuit breaker.
