Power cord Instruction manual Calibration Report Communication cable Software installation disk 6 2Connect the power cord and turn on the power supply When you turn on the power supply, the front- panel display wil

16、l light up briefly while the power supply performs its power- on self- test. All the VFD annunciators will turn on at once. Check for any missing display segments. In the event that there is no response when you turn on the power supply, refer to section 5 of this chapter for additional information.

17、 3. System Checkout At power up, the instrument will automatically perform a self test routine. During this time, the following should be displayed: System Test, Please wait! followed by 0.000V 0.000V 0.000V Or: Note: The first row is the output voltage for channels 1 3. The second row will display

18、the on/off state or the output current of each channel. In case the self test routine is not successful, you may see one of the following: If the EEPROM is damaged, the VFD will display the following: EEPROM Error If the last operation data which should be stored in the EEPROM was lost you should se

If the calibration data in the EEPROM is corrupted or the factory calibration values are lost, the VFD will display the following: Lost Factory Calibration Note: You will see a “?” on the VFD, in case of any errors are encountered during the self test routine. 4Output Verifi

21、cation The following procedures verify that the power supply outputs the correct voltage and current levels and properly responds to entries from the front panel. ? Voltage Output Checkout The following steps verify basic voltage functions without load. 1) Turn on the power supply. 2) Turn on the ou

22、tputs using the On/Off key Note: Flashing voltage values indicates that the power supply is in “Set mode, Set mode means that the VFD display shows the set values for voltage and current. In “meter mode” the display will indicate the actual output voltage and current. 3) Check that the front- panel

23、voltmeter properly responds to number key entries Enter a different voltage value and wait a few seconds until the meter mode activates. Verify that the actual output value voltage is identical to the set value. Also verify that the displayed current value is close to zero. 4) Ensure that the voltag

24、e level can be adjusted from zero to the maximum rated value. 5) Verify channels 2 & 3 according to steps 1) 4) ? Current Output Current The following steps check basic current functions with a short across the power supplys output. 1) Turn on the power supply 2) Turn the output off Press On/Off key

25、 to ensure that the outputs are off. (bottom row indicates “OFF”) 3) Connect the (+) and (- ) output terminals of channel 1 with a short, insulated test lead. Use a wire size sufficient to handle the maximum current. 4) Set the voltage value with 1V 5) Turn on the output using the On/Off key. 6) Adj

26、ust the current value Enter a different current value, wait until the instrument is in meter mode, then make sure that the 8 displayed current value (actual output value) is the same as the set value. 7) Ensure that the current can be adjusted from zero to the maximum rated value. 8) Turn off the po

27、wer supply and remove the short wire from the output terminals. 9) Verify channels 2 & 3 according to steps 1) 8) 5If the Power Supply Does Not Turn On Use the following steps to help resolve problems you might encounter when turning on the instrument. 1). Verify that there is AC power applied to th

28、e power supply. Verify that the power cord is firmly plugged into the power receptacle on the rear panel of the power supply. Make sure the power outlet you are using is working properly and verify that the power supply is turned on. 2). Verify the power-line voltage setting. Make sure the voltage s

29、elector switch is set according to the present line voltage (110VAC or 220VAC). Change the voltage setting if its not correct. 3). Verify that the correct power-line fuse is installed.

31、ard 19- inch rack cabinet using the IT- E151 rack mount kit. Note: Remove the carrying handle and the two plastic ears before rack- mounting the instrument. To remove the handle, grasp the handle on the side, pull outwards and rotate it to a special position where the arrow on the handle and the arr

32、ow on the plastic ears are in opposite directions. Now you can pull the handle outwards. After removing the handle, you can remove the two plastic ears with a screw driver. 10 3.

39、tion So far we have covered the quick start chapter which briefly introduced the front panel operation and how to check basic voltage and current functionality. This chapter describes in detail how to operate the instrument manually via the front- panel keys. 4.1 Front-panel Operation Overview ? The

40、 power supply is shipped from the factory ready for front- panel operation mode. At power- on, the power supply will automatically enter the front- panel operation mode and the instrument can be controlled via the font panel keys and knob. The power supply enters remote mode as soon as a valid remot

41、e command is received via the communication connector in the rear. Switching to remote mode does not impact the supplys output parameters. In remote mode, front- panel operation is disabled. If the power supply is in remote mode, and the LOCAL key is not disabled, you can revert to manual mode by pr

42、essing the LOCAL key . ? The power supply is in Meter mode when it is powered on. In this mode, the VFD will display the actual voltage and current output value. If the user adjusts the knob while in this mode, the power supply will automatically enter Set mode then revert back to meter mode and dis

43、play the modified voltage and current values. ? The output of the power supply can be enabled/disabled from the front panel by pressing the On/Off key. ? The VFD also displays operation states or error information. “”means the power supply is in remote mode. If an error occurred, ”?” will be display

44、ed. ? If the power supply is in Set mode, you can modify parameters using the knob. If the power supply is in menu operation, the knob is used for menu selection. If the power supply is in the regular output mode you can use the knob to set the voltage value. ? If “?” is displayed on the VFD, please
