Installation

Thissectionis designed to assistyouin getting a newpowersupply into operation asquicklyand

easilyas possible. Please read the followingvery thoroughly beforeattemptingto install the

instrument.

2.1 ReceivingInspection:

Carefully

unpackthe Hastings PowerSupplyandanyaccessories that arrivewithit. Inspectit for

any obvious signs of damage due to shipment. Immediately advise the carrier if any damage is

suspected.

Compareeachcomponentshippedagainst the packing list. Ensurethatallpartsare present (i.e.

powersupply,cables,etc.).Optional equipment or accessories willbelistedseparatelyonthe

packing list (see Section 1.4 -Accessories). There may also be one or more OPT- options on the

packing list. These normally refer tospecial ranges orspecial gas calibrations. They may also refer

tospecialheliumleaktests or high pressuretestsorspecialmodifications such as hightemperature

orspecial O-ring materials. Inmost cases theseare not separateparts, butrather special optionsor

modificationsbuilt into the powersupply.

2.2 Power Requirements:

TheModel200PowerSupplynormally

operates on either 115 or 230VAC. It

canbeswitchedbetweenthesetwo

Each controller connected to the Hastings Power Supply has a valve override switch. For normal

operationthiswill remain intheAUTOposition. TheCLOSEpositionwillremovepowerfromthe

valve,thusshuttingoff the flowregardlessof the commandsignal. TheOPEN position willsend

themaximumavailable voltage to thevalveensuring that itwillbewide open, independentofthe

commandsignal. The OPENpositionisusefulfor purgingthesystem. Whenthe softstartmethod

ofvalve override hasbeeninstalled as describedin Section 3.2.1,the switch operates byoverriding

thecommandsignal. Thereforewhen monitoringthecommandsignal,thedisplaywilloverrange

high when the valve is opened and over range negative (i.e. -1. - - - ) when the valve is closed.

2.6.2 Display2.6.2 Display

2.6.2 Display

TheDISPLAYswitch,locatedintheupperright handcornerofthe front panel,controlsthe digital

display(refertoFigure2.3). When theDISPLAYswitchisin the FLOW position,thedisplayis

monitoring the mass flowrate. IftheDISPLAYswitchisintheCOMMANDposition the display

ismonitoringthe desired flow rate,alsoreferredto as thecommandsignal,for flow controllers

only. Ifthepowersupply waspurchasedwiththeflowinstruments,thepowersupplywillbe

alreadyset upso that the display reads directly in the unitsof flowto bemonitored.

EXAMPLE: A 5 SLPM unit is connected to channel 1. When the CHANNEL SELECTOR

switch is turned to channel 1,the display will read 5.00 at 5 SLPM flow rate. A 50 SCCM unit will

have the display for its channel read 50.0 at full flow. Note that the display has 3-1/2 digits,but

onlytwo decimal points are active, therefore a 1 SLPM unit willread 1000SCCM.

2.6.3 Channel Selection2.6.3 Channel Selection

2.6.3 Channel Selection

TheCHANNEL SELECTOR switchin thelower right-hand cornerof the front panel isused to

switchthedisplaybetweenthe differentflowinstruments to bemonitored. Notethat the OFF

positionremovesallpowerfromthe flow instruments andfrom most of the powersupply. Ifthe

CHANNELSELECTORswitchis inadvertently turned totheOFFposition,the flow controller

valves willclose. After turningthe instrument back on,there will bea short period of timebefore

controlof the gasflow will resume.

2.6.4 Internal Command2.6.4 Internal Command

2.6.4 Internal Command

Whenanexternal commandsignalis not providedtotheHastingsPowerSupply,it isgenerated

internally by applying a 5 voltreference to thecommand potentiometer on thefront panel. To set

mandpotentiometerofthechannel to be changed clockwisetoincreaseflowrateand counterclock-

wisetodecrease flow rate.

2.6.5 External Command2.6.5 External Command

2.6.5 External Command

TheHastingsPowerSupplycan be setupto accept anexternalcommand signal suchasthe output

from a D/A converter. When operating in this mode,the signal from the D/A converter is con-

nectedtothe external command inputterminalson the back ofthepower supply (see Figure2.4).

There is a plus (+) and a minus (-) terminal for each channel. NOTE: All four negative terminals

are tied together and to the flow common terminal inside the power supply. If this mode of

operationwasnotspecifiedon the original order, therewillbeaninternal dipswitch that must be

set. See Section 3.3 to set this. When operating with a 0-5 volt external command signal the

commandpotentiometer onthe frontpanelmustbe setfully clockwise. Thiswillresultin the

external command signalbeingsentdirectlytothe controller. Thecommandsignalcan be moni-

toredbyturningthe Flow/Command switch toCommand. Ifanexternal command signalgreater

2.6.6 Slave Controllers2.6.6 Slave Controllers

2.6.6 Slave Controllers

The Model 200 Power Supply can be configured to slave one flow controller to another controller or flowme-

ter. This is commonly used to generate gas mixtures when varying flowrates are desired. Either channel can

be set up as the master or the slave. Normally, the master will be a flow controller and will be controlled by the

command potentiometer on the front panel for its channel. Occasionally the master will be a flowmeter which

is controlled by an external throttle valve. The slave will be a flow controller that has its command input tied to the

master’s flow output. The slave controller will follow the master’s lead.

When the master increases, the slave will increase. When the master decreases, the slave will decrease. This

results in a constant ratio of the two gases regardless of the flowrate through the master. The command potentiom-

eter on the front panel for the slaved controller adjusts this ratio between 0 and 100% of full scale. Turning the ratio

control clockwise increases the ratio of the slaved gas to the master. Counterclockwise decreases the ratio.

The output of the slave controller cannot exceed the command input voltage. EXAMPLE: If two 10 SLPM

full-scale flow controllers are used and the primary controller is set to 50% of full scale, the slave controller cannot

be adjusted using the front panel potentiometer for more than 50% of full scale. If the slave controller must have

more flow than the primary controller, the slaved controller requires a higher full-scale range than the primary

controller or the controller which is primary may be changed to the slave controller and vice-versa. Ajumper wire

must be installed on the rear terminal board from the master’s Flow out terminal to the + External command input

channel for the slave. The negative terminals are internally connected.

If this mode of operation was not specified on the original order, there is an internal command source selector

dipswitch which must be set to the external position. See Section 3.1.3 to do this.

2.6.7 Fuse2.6.7 Fuse

2.6.7 Fuse

The fuseholder is mounted on the lower right-hand corner of the back panel. To remove the fuse, unplug the

unit from the power supply, insert a screwdriver into the slot, and turn counterclockwise 1/4 turn. Replace the fuse

with a 250 volt 1/2 amp Slo-Blo fuse, 1/4" x 1-1/4". Insert fuse into fuseholder. Place into fuse base and turn

clockwise 1/4 turn. Attempting to turn past the stop may damage the fuseholder.

3.2 Switch Change:

The valve override switches on the front panel of the Hastings Power Supply are normally set up

for an OPEN -AUTO - SHUT configuration. This method results in the voltage on pin 8 of the

connectortotheindividual flowinstrumentbeing forced todifferentvalues. +15VDCdrives the

valve open,-15VDC closes the valve,and if pin 8 is left floating,the valve will be in the flow

controlmode. The valveis fast-responding and has rapid recovery when returningto theAUTO

mode.

Thisoptionbypassesmostof the electronics in thecontrolcircuitofthe flow controller, including

thesoftstart circuit.The soft startwill be activewhenchangingthe command signal iftheswitchis

intheAUTOmode,butthe controller will haveovershoot or undershootwhen switching to the

AUTOposition from theOPENor SHUT positions. Thereare jumpers in thepowersupply

thatcan be changedtoput soft start intotheswitch. Thisisaccomplishedbyoverriding the

command signal to the HFC unit. See Section 3.2.1 to set up this option. When using this option,

there will be no overshoot or undershoot when switching from SHUT or OPEN to theAUTO

position,butthe valve will besloweracting.

3.2.1 Soft Star3.2.1 Soft Star

3.2.1 Soft Startt

For this change to be effective, there is a jumper inside the HFC cover which must also be moved.

See the HFC manual for instructions. To change to the soft start method of valve override,

remove the two screws on thetop ofthe back paneland slidethe aluminumperforatedtopcover

from the unit. When looking from the frontof the unit, there are two jumpers on the rear of the pc

boardin front ofthe“D”connectorsand under theflex cable (seeFigure 3.2). Each jumperwill be

onaseries of threesquarepins. Ifthe power supplywaspurchased with astandardsetup, both

jumpers should be on the left two pins as shown in Figure 3.3. To change to the soft start mode,

remove the jumper for the channel to be changed and reinstall it on the other two pins as shown in

Figure3.4. Reinstall the top cover. With this method of valve control,there will be an approxi-

mate fifteen second delay when switching from override CLOSED or override OPEN to the

AUTOposition.
