  • Page 60: Standard (Local) Operation

    Local Operation Standard (Local) Operation The power supply can be controlled by two methods, either from the front panel or from any of the remote interfaces. Front panel control is referred to as local operation (default setting) while control via any of the remote interfaces is called remote operation.
  • Page 61 Local Operation The mode of operation is not determined until the output is enabled. The Output disabled CV and CC mode LEDs will not indicate the mode while the output is disabled. Constant Voltage (CV) Mode Operation If the output is enabled and the configured current set point is much higher than the requirements for the attached load, then the voltage will rise until it reaches the voltage set point.
  • Page 62 Local Operation Automatic Mode Crossover Mode crossover occurs when the unit makes the switch between operating modes. Crossover can occur from CV to CC or vice versa, depending on how the attached load resistance changes. Figure 3-3 shows the relationships between the variables. For example, if the unit was initially operating in CV mode with the output voltage at the voltage set point and the load current below the and the attached load resistance began to decrease, the current...

  • Page 63: Figure 3-3 Operating Modes

    Local Operation The reverse operating mode change can also occur if the load resistance is increased to the point that the required load current drops below the value. At that point the power supply would crossover to CV mode and the load current would be free to vary as the load resistance changed.
  • Page 64 Local Operation Once the desired value has been set, press the rotary Adjust/Enter control to commit the setting. Important: The control circuits have been designed to allow you to set the output voltage up to 105% over the model-rated maximum value. The power supply will operate within these extended ranges, but full performance to specification is not guaranteed.

  • Page 69: Alarms And Errors

    Local Operation Alarms and Errors Several conditions can cause alarms in the XG/XTR. Some conditions are: From user configurable features. Controlled in hardware and will trigger regardless of configuration. All alarms, with the exception of the Fan alarm, will result in the output of the power supply being disabled.

  • Page 70: Clearing Alarms

    Local Operation Clearing Alarms Clearing Triggered and Manual Alarms To clear a triggered alarm, use one of the following methods: Turn the power supply Off and then On. Press and hold the rotary Adjust/Enter control for 3 seconds. To clear a manual alarm: Press and hold the rotary Adjust/Enter control for 3 seconds.

  • Page 71: Front Panel Alarm Led

    Local Operation Clearing Automatic Alarms Some alarms will clear automatically when the condition that caused the alarm is no longer present. When an alarm automatically clears, the output voltage and current displays will return to normal, but the ALARM LED will remain illuminated to indicate that an alarm has occurred.

  • Page 72: Alarm Masking

    Local Operation The alarm LED will remain illuminated until the alarm is manually cleared (see “Clearing Triggered and Manual Alarms” on page 3-22) or by turning the main output on if the alarm has automatically been cleared. Alarm Masking It is possible to completely disable some alarms through the use of the alarm mask.

  • Page 73: Alarm Output Latching

    Local Operation Alarm Output Latching When an alarm is triggered, the output will be disabled with the exception of the Fan alarm. When an alarm is cleared, the alarm output latch determines if the output should be re-enabled to the state before the alarm occurred or if the output should remain in the off state.

  • Page 74: Setting Foldback Mode

    Local Operation Setting Foldback Mode Foldback mode is used to disable the output when a transition is made between the operating modes. The power supply will turn off/disable the output and lock in foldback mode after a specified delay if the power supply transitions into CV mode or into CC mode, depending on the foldback mode settings.

  • Page 75: Resetting Activated Foldback Protection

    Local Operation Press the rotary Adjust/Enter control to commit the setting once the desired value has been set. The green FLD LED will turn off and the display will return to the normal display mode.

  • Page 76: Using Over Voltage Protection (Ovp)

    Local Operation Using Over Voltage Protection (OVP) The OVP circuit protects the load in the event of an analog programming error, an incorrect voltage control adjustment, or a power supply failure. The OVP circuit monitors the output voltage at the output of the power supply and will disable the output whenever a preset voltage set point is exceeded.

  • Page 77: Defining The Ovp Set Point

    Local Operation Defining the OVP Set Point To define the OVP set point: Turn the power supply On. Ensure the voltage is lower than the desired set point. Set the output to the desired voltage. OVP can be set without setting desired output voltage first. Turn the 9-position mode control to the PRT position.

  • Page 78: Using Under Voltage Protection (Uvp)

    Local Operation Using Under Voltage Protection (UVP) Important: UVP will not be active for voltage set points that are less than 1% of model voltage. The UVP prevents voltage settings below a set value. The UVP lets you create a voltage window of operation when used in conjunction with the OVP setting.

  • Page 79: Defining The Uvp Set Point

    Local Operation Defining the UVP Set Point To define the UVP set point: Turn the power supply On. Set the output to the desired voltage. Turn the 9-position mode control to the PRT position. is displayed. Turn the rotary Adjust/Enter control until displayed.

  • Page 80: Using Over Temperature Protection Lock (Otp)

    Local Operation Using Over Temperature Protection Lock (OTP) The OTP lock protects the power supply in the event of an over temperature alarm. This alarm could be caused by ventilation restriction or overheating due to fan failure. Two modes are available: Auto recovery (OTP OFF) where the power supply turns on again after cooling down.

  • Page 81: Using The External Shutdown Function

    Local Operation Using the External Shutdown Function Use the external shutdown function to enable or disable the output of the power supply via a logic level signal. When the external shutdown is triggered, the power supply will display SD POL on the output voltage and current displays.

    Local Operation Defining the Polarity of the External Shutdown Signal Turn the 9-position mode control to the PRT position or press the rotary Adjust/Enter control if the control knob is already at the PRT position. is displayed on the output voltage display. Turn the rotary Adjust/Enter control until displayed.

  • Page 83: Setting Up Loop Protection

    Local Operation Setting up Loop Protection To set up Loop Protection: With the AC powered OFF, connect the first unit’s pin J13.13 to the next unit’s J 13.12 on the AUX Output and Isolated Analog Programming Connector. Do this for up to four units. An example of a 3-unit loop protection is illustrated as follows: To enable or disable Loop Protection: Turn the 9-position mode control to the PRT position.

    Error Messages Appendix B, Error Messages, provides information on the error messages which may appear. Errors are placed in a queue as they are detected.

  • Page 342: Error Messages

    Error Messages Error Messages Errors are placed in a queue as they are detected. The queue works on a first in, first out (FIFO) basis. If the queue overflows, the last error in the queue is replaced with error -350, “Queue Overflow”. When all errors have been read from the queue, further error queries return 0, “No error”.
