Page 69: Using Over Voltage Protection (Ovp)
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 70: Defining The Ovp Set Point
Local Operation Defining the OVP Set Point To define the OVP set point: 1. Turn the power supply On. Ensure the voltage is lower than the desired set point. 2. Set the output to the desired voltage. OVP can be set without setting desired output voltage first. 3.
Page 71: Using Under Voltage Protection (Uvp)
Using Under Voltage Protection (UVP) Important: 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. The UVP range is variable from 0 V to OVP The UVP is a protection that becomes active after the output is enabled and a period of time has passed to allow the output to reach its set point value before the UVP protection begins monitoring.
Page 72: Defining The Uvp Set Point
Local Operation Defining the UVP Set Point To define the UVP set point: 1. Turn the power supply On. 2. Set the output to the desired voltage. 3. Turn the 9-position mode control to the PRT position. PRo OUP is displayed. 4.
Page 73: Using Over Temperature Protection Lock (Otp)

When the switch is closed the power supply will operate normally. If the switch is opened, the power supply will trigger the interlock alarm.
Page 77: Power On Status Signal
Power On Status Signal Power On Status signal indicates a fault condition in the power supply. Power On Status signal is a TTL output signal at Pin J2.13 with reference to COM_ISOLATED (Pin J2.2 or Pin J2.6). During normal operation, the Power On Status signal will be high. If the output is disabled for any reason, the Power On Status signal will go low.
Page 78: Current Configuration Memory Settings
Local Operation Current Configuration Memory Settings The power supply will save the unit settings at the time of power down. These settings will be loaded when the power is restored to the unit or the power supply is powered up again. Table 3-7 lists the settings that are saved and recalled on a power cycle event.
Page 79: User Setting Memory Locations
User Setting Memory Locations There are three user setting memory locations available for storing frequently used configurations. These user setting memory locations help to facilitate multiple users of an XTR power supply who have different setups or when multiple loads are used that have different requirements. Table 3-8 lists the values that are stored in each user setting memory location.
Page 80: Recalling User Setting Memory Locations

Status Registers Model from IEEE 488.2 The IEEE 488.2 registers shown in the bottom rectangle of Figure 5-16 follow the IEEE 488.2 model for status registers. The IEEE 488.2 register only has enable registers for masking the summary bits. Figure 5-17 shows the details on the relationship between the mask/enable registers and the summary bits.
Page 154: Status Byte
Remote Operation Status Byte The Status byte register contains the STB and RQS (MSS) messages as defined in 488.1. You can read the status byte register using a 488.1 serial poll or the 488.2 *STB? common command. The *STB? query causes the device to send the contents of the Status Byte Register and the Master Summary Status (MSS) summary message.
Page 155: Message Available (Mav)
Message Available (MAV) This bit is TRUE whenever the power supply is ready to accept a request by the Digital Programming Interface to output data bytes. This message is FALSE when the output queue is empty. Standard Event Status Summary (ESB) This bit is TRUE when a bit is set in the Standard Event Status Register.

Page 237: Main Voltage And Current Calibration Principle
Main Voltage and Current Calibration Principle Understanding the Problem Figure B-1 illustrates two sources of analog programming error: gain error and offset error. Gain error is the departure from the ideal slope of the measured versus programmed line. Offset error is the magnitude of the measured value when the programmed value is zero.

Page 240: Calibrating The Output Voltage
Calibration and Troubleshooting Calibrating the Output Voltage Gain calibration of the power supply has the greatest affect on the accuracy in the high voltage range. Offset calibration has the greatest affect on accuracy of the power supply at low voltages. The same calibration command is used for the gain and offset calibrations.
Page 241: Calibrating The Output Current
After performing offset calibration, Xantrex recommends that you repeat gain calibration. Important: For best results, both calibrations may be repeated several times. The SCPI Command (s) for these instructions are: [:]CALibration[<channel>]:OUTPut{:VOLTage]{<voltmeter reading in volts>} Calibrating the Output Current Gain Calibration To perform gain calibration: 1.
