4. Push AC ON green pushbutton marked '|'. The AC ON LED should be illuminated after the mains contactor
closes.
5. The front panel display should show the model/frequency of the unit and the software version number for
the first two seconds. The front panel display should show 'REM' for remote control. Push the mode select
key (>>) on the front panel to select LOCAL control.
6. Enable RF by pushing the blue RF button on the left side of the front panel. The RF button should
illuminate, the display flash 'RF ON', and readings of forward and reflected power should appear. If the
display shows 'CHECK RF INTERLOCK', this means that the RF enable Pins 4 and 9 of rear panel
connector are not jumpered.
7. RF is disabled by pushing the RF button again, by removing RF interlock by disconnecting Pin 4 and 9 of
rear panel connector, or by interrupting the AC mains via the AC interlock loop, the stop softkey, or the
circuit breaker located on the rear panel.
8. The CX600 regulates forward power based upon the setpoint selected by the large data encoder knob on
the front panel.
9. The CX600 can be programmed to linearly ramp up and down the RF output power when RF is enabled or
disabled. This is done by pushing the function select softkey (>) once to adjust the upramp time, and
once more (>) to adjust the down ramp time. The times are programmable from .1 to 10 seconds, in .1
second incre ments through turning the data encoder knob on the front panel. Pushing the function select
softkey a third time (>) brings the data encoder knob adjustment back to forward power setpoint.
10. An overtemp condition due to improper clearance around the u nit or high ambient temperature will
automatically disable RF the CX600. The front panel display will show 'OVERTEMP' for about 2 seconds if
the RF ENABLE softkey is pushed. RF will not be able to be turned on until proper coolant
flow/temperature is established.
B. Remote Control Operation
1-4. Refer to Figure CPS REMOTE INTERFACE DEFINITION for the electrical interface specification. For
remote control operation follow the first four procedures for local control as listed above.
5.
Remote operation is the power-up default mode. If the current mode of operation is LOCAL, then push
the mode select key (>>) until the display shows 'REM' in the upper left corner OR restart the unit by
turning AC off then back on.
6.
Enable RF by jumping the RF ENABLE pins 4 and 9 of the rear panel connector. The RF button should
illuminate, the display flash 'RF ON', and readings of forward and reflected power should appear.
7.
The voltage on Pin 5(+) and 6(-) of the J1 connector will determine the output power level. A voltage of 0
to 10 volts DC across Pins 5 and 6 (chassis ground) will linearly correspond to an RF output of 0 to 600
watts.
8.
Reflected and forward power can be monitored remotely through Pins 2(+), 6(-) and 3(+), 6(-) respectively.
Both of these balanced analog outputs are 0 to 10 VDC linearly corresponding to 0 to 200 watts of
reflected power and 600 watts of forward power respectively.
9.
An overtemp condition as stated in #10 above in LOCAL will also result in the 'closure' of the
OVERTEMP DIGITAL OUTPUT, Pins 8 and 9 (chassis ground) of the rear panel connector. The digital
output opto-isolator will be turned on.
11. When RF is present at the RF output connector, the POWER ON DIGITAL OUTPUT, Pin 7 will be at
approximately 5V.
