5. GENERAL OPERATION PRINCIPLE There are four operation methods for this unit: Manual Operation Presets Timed Program PC Interface Mode. The large Liquid Crystal Display will guide you through the various operations/procedures interactively once you understand the operation principle. There are four Dual Function Control Keys for various operation modes and input states of the unit. To change/set operation mode (output on /off, key lock & etc.
6. OPERATING INSTRUCTIONS 6.1 Setting of Operation Modes Output On/Off Mode 1. 2. Press SHIFT key. The display will show Sh:Ft. Press (O/P On/Off) key within 3 seconds. Watch for the appearing On/Off symbol in the display to confirm your setting, otherwise repeat the above procedure. Lock/Unlock the Keypad and Jog Dial 1. 2. Press SHIFT key. The display will show Sh:Ft. Press (Lock/Unlock) key within 3 seconds.
OPERATING INSTRUCTIONS Precaution Reset back to the maximum rated voltage of the unit is recommended to avoid false fault report of the unit 1. Press SHIFT and follow by 0 key. 2. The display will show 3. Input your desired voltage followed by ENTER to confirm. 4. Recheck setting by repeating step 1. and the present upper voltage limit.
OPERATING INSTRUCTIONS Showing output terminals in ON/OFF state. Showing keypad & Jog dial are in Locked (de-activated) or Unlock (activated) state. Unit is ready for or has already been linked up with computer. OUTPUT ENABLE/DISABLE AT POWER UP Press the SHIFT then the UP key. This will enable the output at power up. i.e. When you switch on the power supply, the output is also on automatically with last set voltage value. Press the SHIFT then the DN key. This will disable the output at power up.
STANDARD OPERATION SYMBOLS V- const Constant Voltage mode showing set voltage. V- set This only appears voltage level is ready for setting. I-set This only appears current level is ready for setting. I-const This only appears when unit is in (CC) constant current mode. They show the actual Volts, Amperes and Watts at the output terminals.
6.2 Manual Operation Mode In the Manual Operation Mode, once the voltage and current levels have been set, the unit wi11 keep these settings even after unit has been switched off until further reset. There are 3 ways to input a setting: 1. By the Jog Dial. 2. By the UP or DOWN key. 3. By the Key Pad. For any wrong input, e.g. out of specification values, display will show "OUT OF RANGE" FOR ABOUT 3 SECONDS, then returns to it's previous settings and ready for correct new input.
7. USING THE PRESET FEATURES PRESET PROGRAM SYMBOLS Program Unit is ready for inputting of a Preset Program Number (19). Recall Unit is ready for recalling a Preset Program Number. The unit can store nine preset voltage and current settings. Once programmed, these settings will be retained even when the unit is switched off. Preset Programming 1. Press PROG key The display will show Program_ Key in Program Number (1-9) at the keypad 2. The display will show :a) The newly keyed in Program Number.
Selecting Presets 1. Press the RECALL key The display will show Recall_ 2. Press the number key (1-9). The display will show the chosen Preset Number, its voltage and current level. 3. Press ENTER to activate .The unit will resume the chosen reset values. If during any of the above procedures, you fail to input a setting within 10 seconds, the unit will cancel the procedure and resume the previous settings.
Note: A. B. C. D. Once the subprograms are filled, the unit will return to manual operation mode. Any subprogram with zero time period will become the Terminating Subprogram. For example, if you set the subprogram 7 with zero time period, all the subprograms after 7 (i.e. 8, 9, 10-19) become non-existent. The timed program will only cycle from subprogram 0 (STEP) to subprogram 6. You can use this feature to cut off the subprograms that are not required for the sequence.
TIMED PROGRAM SYMBOLS 1.
2. Symbols Running in a Timed Program Cycle Unit is ready for the recheck of all subprogram settings.
8. MAINTENANCE 8.1 RECALIBRATION Introduction This in-case recalibration is to reduce the difference between the Set values and the displayed values on the LCD Display. You only use the recalibration when the difference is greater than 0.1V for voltage or -0.01A / +0.02A for current. The whole recalibration for voltages and current takes less than 15 minutes. It is performed by a proprietary software using regression algorithm. The recalibration software is compatible to Window XP, Me, 2000, 98SE, 98.
8.2 TROUBLE SHOOTING 1. Keypad and Dial do not work. Check key lock symbol for lock state, unlock unit by pressing SHIFT then Lock/Unlock key, otherwise switch the unit off and then back on to see if the problem persists. 2. No output power. Check the output for on/off symbol on the display. Press SHIFT O/P ON/OFF key. 3. Cannot get a high voltage setting within the rated maximum. Check the upper voltage limit setting by pressing SHIFT then the 0 key. Reset to the rated maximum voltage. 4.
9. PC INTERFACE CONTROL USER MANUAL 9.1 Introduction We integrate the micro-controller technology and our proprietary software with switching mode power technology to make this unit user friendly, time saving and reliable power supply. In PC interface mode: 1. With our proprietary software one PC can perform remote access/control and output data logging for one programmable power supply with RS-232 or up to 31 programmable power supplies using RS-485 interface. 2.
9.3 Operation Instruction for RS-232 Interface 1. Ensure that the PC is off; connect RS-232 to serial COM port of your PC and the power supply. 2. On your power supply, press the [SHIFT] key, and then quickly press [RS-232/485] key and select RS-232 (pressing the [RS-232/485] will toggle between RS-232 and RS-485) followed by the [ENTER] key. 3. Switch your PC and run the program. 4. Click on Setup, and select the desired COM port. The default is set at COM port 1. 5.
1. Setting Once you bring up the software you can your desired sample time from 1 second up from the drop menu. Data log Sampling Time You can set your output voltage upper limit value to further safeguard your low voltage applications. Voltage Upper Limit Setting 2. Data Log window A). You can use the Data Log window to view present output data or stored data. B).
3. Log Name Click cursor on "Untitle", type in a name for your log. Note how the ###(5) icon changes to solid color. 4. Log Description You can type in a detailed description of your log. 5. ##### Save Log a) b) c) 6. This function (and the icon) becomes effective when a Log Name is entered to replace the "Untitle". By clicking on it will save the current data onto the PC. To retrieve the data, go to the drop menu at (3) Log Description.
THE DATA LOG WINDOW DISPLAY 25
THE TIME FRAME CONCEPT OF DATA LOG The data logging function starts when the software begins to run. When T Min is set to zero seconds, it means the unit is on real time and the length of time lapsed is on the left hand side of the Time Minimum. T Len is the length of time lapsed strafing from the Time Minimum. Both parameters are adjustable so that any time period of the log can be displayed for analysis.
GENERAL INFORMATION Please refer to (Fig. 3) for the following description. 10. Power Supply Description: serial no S2405000 You may click on and assign an identification number for your power supply in use. Actually this feature is used mainly when you have multiple power supplies in use via the RS-485. 11. Address: This function is for multiple power supply applications. Each power supply has a unique address. Ignore this function when using RS-232. 12. Voltage: ##.
Internal Timed Program The PC interface remote mode really eliminates the tedious process in keying in groups of entries on the power supply. Because all the data are displayed together in the monitor, the possibility of wrong entry is greatly reduced. Data of different groups can be classified, store, exported and retrieved for use at any time. Retrieved data will be in red color if they exceed the present pre-set limits of voltage in upper voltage level or current limiting value.
Internal Preset Memory The operation principle is the same as Internal Timed Program To activate the selected preset, click on the box of the [Select] column then click Run. If retrieved or entered data exceed present Upper or Lower limit setting of voltage/current/time, the data becomes red in color. 9.4 Operation Instruction for RS-485 Interface This interface operation is provided for remote access/control up to 31 power supplies.
