    NOTE: Before installing equipment, carefully read and familiarize yourself with the entire operations manual. Observe and obey all WARNING and CAUTION notes provided. I. Safety Information Warning Label and Safety Marking Explanations: The following symbols and terms may be found on an instrument or used in this manual. The CE mark indicates compliance with all currently applicable directives and standards.
  • Page 4 The WARNING heading used in this manual explains dangers that might result in personal injury or death. Always read the associated information very carefully before performing the indicated procedure. The CAUTION heading used in this manual explains hazards that could damage the unit. Such damage may invalidate the warranty.
  • Page 5 CE Mark Specific Safety Requirements • This equipment meets all applicable safety directives (as specified in prEN50178) required to qualify for the application of the CE marking. • This equipment must be installed in accordance with the applicable requirements, or prEN50178 and EN60204-1 / IEC-204-1.

    50 ohm output and a digital drive level of 0-5 V. The CX600 series amplifier is constructed with two main sections. The dc power section is contained in the center of the unit. This section includes the filter capacitor, rectifier and regulators as well as the single-phase 208 Vac power transformer.

    Pin 8: DO, Indicates status of heat sink temperature, LO = HOT, FLOAT = OK Pin 9: Digital I/O return for Pins 4, 7, & 8 (chassis ground). Pins 11 & 12: AC Interlock loop, Jump to enable AC power to unit. B.

  • Page 9: Testing Specifications

    If there is shipping damage or the unit fails to operate properly upon receipt, report damage to the carrier and Comdel immediately. CAUTION: Breaking the seal or removing the warranty decal from this unit will void the warranty. If internal damage is suspected, contact factory for assistance.

  • Page 10: Preparation For Use

    V. Preparation For Use A. Line Requirements The CX600 is designed to operate from a 208 Vac single phase line. The system will still function within specifications when the line voltage fluctuates between 190 volts and 225 volts. Voltages over the recommended 208 Vac, however, reduce the safety margins designed into the system and should be avoided.

  • Page 11: Remote Operation

    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.

  • Page 12: Serial Operation (Optional)

    C. Serial Operation (Optional) The following is a description of the RS-232 ASCII instruction set to operate the CX series of RF generators. The baud rate is selectable via a DIP switch on the uP control PCB behind the front panel and is factory set to 9600 baud, N, 8, 1, with echo. 1.
  • Page 13 If the external RF interlock connection is interrupted (15 pin rear panel analog remote interface connector), the RF output will not be enabled, and the CX600 will respond with the message: "CHECK RF INTERLOCK". If RF output is already turned on when the RF interlock is interrupted, the CX600 will respond with the same message and disable RF output.

  • Page 14: Theory Of Operation

    Upon receipt of this ASCII character the CX will disable RF power, set the power setpoint to zero, issue a "<CR><LF>BYE" response, then redirect control of the CX to the mode the unit was previously in when the attention command (!) was given. Local control can now be commanded from the front panel mode select button.

    The high current required by the RF power amplifier (PA) is monitored by the HALL EFFECT CURRENT MONITOR PCB (Figure FA0502RX) mounted on the 40V DC filter capacitor. This PCB uses a Hall effect device to monitor the DC current feeding the PA600 RF power amplifier. C.

    circuitry to limit forward power in cases of high PA current or high PA RF voltage. This protection function is handled by U1. 2. CX MICROCONTROLLER PCB This PCB (Figure FA0604RX), mounted under the CX INTERFACE PCB, contains a 16 bit microprocessor, memory, digital I/O, and analog I/O to control and monitor all activities of the CX600.
