The ITS Team will be performing maintenance on Confluence beginning at 6:00 pm Tuesday, May 6. During this time the service may go offline. It should be available again by 8:00 pm. Please refrain from editing pages during this time to avoid losing your work.
SAFETY PRECAUTIONS
Caution; EIKs produce millimeter wave radiation, which can be dangerous to personnel. Before operating an EIK CW system, ensure that appropriate waveguide connections are in place.
Caution; never apply prime power to the CW power supply with any of the connections open; irreparable damage may result and an operator hazard may exist.
Follow all instructions presented in Installation Instructions (EIK) prior to applying prime power.
The CW power supply incorporates protection to the EIK through the use of trips and limits preset at the factory. The user is responsible for incorporating prime power fusing, personnel safety and cooling interlocks.
OPERATION
Stand-By Mode
Apply AC power by turning on "MAIN POWER" switch/breaker. The internal cooling fan should be heard running. After several identification messages on the front panel display, MENU 1 will appear.
The fourth line will display [HTR TD: **] which indicates the remaining number of seconds of heater (filament) warm-up high voltage delay. When the heater warm-up delay has expired, the message [Stdy / rdy] will be displayed. No high voltage operation is possible until "STAND-BY / READY" is displayed.
If the external cooling interlock is not satisfied, the lower display will indicate "EIK OVER TEMP".
*Ea in the lower display is only displayed when in calibrate / adjust mode.
While in STAND-BY mode, a small square next to Ea and Ek indicates that the preselected operating value is displayed.
Caution; do not leave the EIK operating in STAND-BY mode for extended periods of time. Operation of the heater without high voltage for periods greater than 1 hour may create poor high voltage application conditions and potentially producing cathode damage.
OPERATE Mode
Pressing the "OPERATE" button will turn on the cathode and collector voltages to their preselected values. The display will now indicate the measured values of Eb (collector voltage) and Ek (cathode voltage). If utilizing the DIVIDED ANODE voltage terminal, the EIK will now be conducting nominal cathode current and be RF capable. However, if utilizing the REGULATED ANODE terminal, with only cathode voltage applied, no significant Ik or Iw will be conducted by the EIK.
RF ON Mode
Pressing the "RF ON" button will turn on the (REGULATED) anode voltage to the preselected value. The EIK will now be operating at preselected voltages and current.
Shut Down Sequence
Press the "RF OFF" button to turn off the (REGULATED) anode voltage. Press the "STAND-BY" button to turn off the cathode voltage.
Alternatively, pressing the "STAND-BY" button only will properly sequence off both voltages.
Caution; do not leave the EIK at voltages other than those found on the EIK Final Test sheet (Specifications) may result in permanent EIK
