User Manual ENTRY ALC STATE 2253i / 2253iX DESCRIPTION STAN Power up in INT (internal) clock mode for standalone operation. This is the only mode for models without the –LKS option. For units with the –LKM option installed, this field is fixed to CLK/LOCK. For units with the –LKS option installed, this field can be changed to CLK/LOCK for use as an auxiliary unit in a clock and lock system or to STAND for use as a stand alone unit.
PAGE 63
User Manual 2253i / 2253iX ENTRY DESCRIPTION # OUTPUTS Selects SINGLE or THREE phase mode of operation. If the –MODE option is installed, this field can be toggled on the 2253i / 2253iX. If no –MODE option is installed, this phase will always be set to THR for three phase mode. ST PHASE Selects the start phase angle for output changes made to either voltage or frequency. This allows changing the output at a specific phase angle.
PAGE 64
User Manual 2253i / 2253iX 4.2.6 MEASUREMENTS Screens The i/iX Series uses a DSP based data acquisition system to provide extensive information regarding the output of the Source. This data acquisition system digitizes the voltage and current waveforms and calculates several parameters from this digitized data. The results of these calculations are displayed in a series of measurement data screens. A total of three measurement screens are used to display all this information.

User Manual 2253i / 2253iX 4.4 Waveform Management The iX Series employs independent arbitrary waveform generators for each phase. This allows the user to create custom waveforms. In addition, three standard waveforms are always available. This chapter covers issues that relate to defining, downloading and managing custom waveforms. Note: i Series models do not support arbitrary waveform generation. 4.4.1 Standard Waveforms For most AC applications, a sinusoidal wave shape is used.
PAGE 81
User Manual 2253i / 2253iX 4.4.3 RMS Amplitude Restrictions The output of a sine wave may be programmed to the full rms value of the voltage range selected. If the AC source is in the 300 V range, the maximum programmable rms voltage is 300 Volt. If a custom waveform is used however, the maximum programmable rms voltage may be less than the maximum range value. The voltage range limit is based on the use of a sine wave with a 1.414 crest factor. A 300 V rms sine wave has a 424 Volt peak voltage.

User Manual 2253i / 2253iX 6. Calibration The Routine Calibration should be performed every 12 months. Non-routine Calibration is only required if a related assembly is replaced or if the periodic calibration is unsuccessful. Calibration of the i/iX system can be performed from the front panel or over the bus. This section covers calibration from the front panel. 6.1 Recommended Calibration Equipment Digital Multimeter: 10 mOhm Current Shunt: Load Bank: Fluke 8506A, 8508 or equivalent.

User Manual 2253i / 2253iX The shunt must be connected in series with the load. Connect the load to the output. Use a 10 mOhm current shunt of sufficient power rating in series with the load to measure the AC load current. To calibrate all measurement functions, the desired value for the measurement value of current or voltage must be entered for the corresponding calibration value. Make the indicated adjustments by typing in the desired display value.

User Manual 2253i / 2253iX 6.4 Non-Routine Output Calibration The output calibration will not affect the accuracy of the output voltage when the ALC mode is either ON or in REG mode. In these modes of operation, the output voltage accuracy is determined by the voltage measurement accuracy. The calibration shown in this paragraph will be influenced by the gain of the power amplifier for each phase.
