Operating Instructions 29 3 OPERATING INSTRUCTIO NS Introduction This section describes the operating controls and indicators, turn- o n checkout procedures, and operatin g procedures and considerations for the power supply .
Operating Instructions 30 Before the instrument is turned on, all protective earth terminals, extension cords, and devices connected to the pow er supply should be connected to a protective earth g round. Any interruption of the protective earth grounding w ill cause a potential shock hazard that coul d result in personal injury .
Operating Instructions 31 Load Resistance B equals th e crossover resistance for the particular com bination of voltag e and current settings sh own on the graph. Either the CV or CC LED will light. If the load resistance increases, the voltage setting decreases, or the current setting increases, the power supply w ill operate in CV mode.
Operating Instructions 32 Table 3-1. Controls and Indicators (continued) Number Controls/Indicators Description Page 2 GP-IB Status In dicators These four LEDs indicate the status of the power supply on th e GP-IB. RMT (green) indicates that pow er supply is under rem ote (GP-IB) control.
Operating Instructions 33 Table 3-1. Controls and Indicators (continued) Number Controls/Indicators Description Page 5 Num eric Disp lay Two 3-1/2 digit alphanumeric displays w ith auto matically positioned d ecimal point that or d inarily indicate output VOLTS and AM PS (see items 6 & 7).
Operating Instructions 34 Once the all-indicators-off period is over, the GP-IB ad dress switch setting is displayed on the m eter d isp lays for one second. For exam ple, if the address sw itches were set for address 5, the display would be: A dr 5 If the unit fails any of the self tests an error cod e is d isplayed on the m e ter d isplays.
Operating Instructions 35 d. Turn OUTP UT ADJUST knob clockw ise, press DISP LAY SETTINGS switch, and ch eck that AMPS setting has increased. C V indicator shou ld be on and CC i ndicator shou ld be off. e. P ress mom entary-con tact OUT PUT ADJUST pushbutton sw itch once; VOLTAGE indicator shou ld turn on and CURR ENT indicator s hould turn off.
Operating Instructions 36 per lead. T able 3-2 lists resistivity for various w ire sizes and the maximum lengths that may be used to limit voltage drop to 0.5 vo lts for va r ious curr ents. Lengths liste d are the sum of the le ngths o f the ( + ) a nd ( - ) lo ad wires.
Operating Instructions 37 If m ultiple load s are connected to one supply, each lo ad should be connected to the supply’ s ou tp ut term inals using separate pairs of connectin g wires. This mi nimizes m utual coupling eff ects and takes full advantag e of the supply’ s low output im pedance.
Operating Instructions 38 Figure 3-5. Connecting a Bypass Capacitor Overv oltage Protection (OVP) The overvoltage trip p o int is adjusted at the front panel. T he approximate trip voltage range is from zero volts to approxim ately 107% of maxi mum rated voltage of the pow er supply.
Operating Instructions 39 Foldback Protection In some applications either CV or CC mode may be regarded as an error condition. T he foldback pro tectio n feature pr o tects sensitive loads by disabling the po wer supply output if the unit sw itches to the pr o hibited mode.
Operating Instructions 40 Figure 3-6. Remote Voltage Sensing Because the sensing leads carry only a f e w milliam peres, the wires u sed for sensing can be mu ch lighter than th e lo ad leads. Each sense lead sh ould have no m o re than 0.2 ohms resistance.

Operating Instructions 42 1. The total n umber of devices is no m ore than 15. 2. The total length of all the cables used is no more than tw o meters times the num ber o f devices connected together, up to an absolute max imum o f 20 meters.
Operating Instructions 43 Foldback. If f oldback protection is enabled (FOLDBA CK ENABLED LE D on) and the pow er supply switc hes to the prohibited mode (CV or CC), the p ower supply output will be disabled and the FOLDBACK indicator turned o n.
Operating Instructions 44 Constant Current Operation To set up the p ower suppl y for constant c ur rent op eratio n: a. With power supply turned off, connect load to output terminals. b. Turn on pow er supply . Hold in DISPLA Y OVP pushbut ton sw itch and set OVP A DJUST potentiom eter for desired OVP trip voltage.
Operating Instructions 45 Multiline M essage Control Functions . The Acceptor Handshak e, Source Handshake, Listen er, and T alker functions are implem ented by th e interface circuits of the pow er supply an d the controller and require no action by the user.
Operating Instructions 46 Remote/Local . The remote/local function allows the pow er sup p ly to operate in either local (front panel) or remote (via GP-IB) control. The user can sen d Local Lockou t to the power supply via GP-IB to disable the front- panel LCL sw itch only.
Operating Instructions 47 Holding the LCL sw itch in for o ne second causes the power supply’ s GP -IB addr ess to be displayed on the front pa nel until the sw itch is released or two seconds elapse. The address switch es are also used during troublesh ooting to select wh ich self tests are run in test m ode.

Operating Instructions 58 DLY 0.500 Note that during the delay period CV and C C are masked f r om the foldback protection feature also. Delay does not af fect the setting of th e CV, CC, o r OR bits in the status register or accum ulated status register; delay aff ects o nly th e setting of those bits in the fault register.
Operating Instructions 59 Reset. Reset rest ores the pow er supply ou tput if it has been disabled by OVP, foldback, or rem ote inhi bit. The output retu rns to the present vo ltage and current settings; the values may be changed wh ile the o utput is disabled.
Operating Instructions 60 completed w ith the first. Therefore, sending device trigger after sending a command assu res that the second instrumen t cannot begin to receive comm ands until the first instru ment has processed its commands.
Operating Instructions 61 For exam ple, if bits for both ERR (128) an d CC (2) are set, the pow er supply wou ld send ASC II digits 1 3 0 (128 +2 = 130). Bits remain set in the status register as long as the corresponding co nditions are true. Table 3-9.
Operating Instructions 62 Note that bits can be set in th e fault register only when there is a ch ange in either the status reg ister or the mask register. Therefore, if a bit is set in the mask register (unm asked ) after the corresponding conditio n becomes true in the status register, the associated bit will also be set in the fault register.
