DRYAIRE HEATER

17400 TEMPERATURE CONTROL ASSEMBLY
OPERATION NOTES
This assembly incorporatesUDC 3000 digitaltemperature controllers. To keep controloutputsfrom
increasingduring the preburn routine, they take their power from the flame signal.
If the heateris
equippedwith
the 16910 ModulatingHighTemperature Limit to controltemperaturebeforethe mix
point,there
will be two digital controllers(one on the left and one on the right). If the 16910 isnot
used, there
will beasinglecontrollermountedon the left. The same assembly isusedon all heaters,
whether they have relayor microprocessorcombustioncontrols.
This assembly hastwoindicatorlights, STATUS and FLAME. Their operationisas follows:
STATUS LIGHT
-- When used with the HG-3-1110heater, this light will be ON duringpreburnroutine
and operation.
On all other heaters, which have microprocessorcombustioncontrols, this light will be
ON while in
operationand preburn and OFF during postburnroutine.
It will indicatealarm and error conditions
byblinkingas explainedbelow.
FLAME LIGHT
-- With allheaters, this lightwill be ON when flame isestablished.
ALARMSAND ERRORS
ALARMS -- Problems notseriousenough toshut downoperation.
ERRORS
-- Problems which requirethat operationscease.
ALARM PROCEDURE
-- Duringoperation, the STATUS light will blink at the rate of one pulse every
twosecondsfor
5 minutesthen revertto ON. Duringthe 5-minuteinterval, the ALARM light on the
local panel will be ON. The counter will display the code number corresponding to the alarm
problem,and
will resetto zero at theend of the interval.
ERROR PROCEDURE
-- The burner will shut downand cannotberestartedunlessthe RESET button
on the localpanelispushed. The counter
will displaythe appropriatecode number and the ALARM
lightwill
be ON until the RESET button is pushed. The STATUS light will blink at the rate of one
pulse per second for
5 minutes, then go OFF. If an attempt is made to start the burner before
RESET, theSTATUS lightwill blinkfor 10
seconds thengo OFF.

USING THE 17400 DIGITAL TIEMPEBATURl3 CONTROL
(WITHTHE 16910 MODULATING HIGH TEMPERATURELIMIT)
The 17400 Temperature Control Assembly for Samuel Jackson Dryaire Heaters can be used with the 16910
ModulatingHighTemperature Limitto preventhightemperatureswhich canharm cottonqualityand, inextreme
cases, cause fires. These instructionswill provideoperating guidelinesfor use of this control arrangementwith
allSamuelJacksonDryaireHeaters.
PRINCIPLE OF OPERATION
The 17400 control assemblyuses two HoneywellUDC-3000digitaltemperaturecontrollers. The controlleron
the
!& as you face the controlassembly is designatedthe "PRIMARY controller. The controller on the riaht is
designatedthe "HIGH LIMIT" controller. The PRIMARY controller has its thermocouple temperature sensor
mountedDOWNSTREAMof the mixpointinthe drying system. The MIGH LIMITcontroller has itsthermocouple
mountedupstream of the mixpoint. The PRIMARY controller watches the temperature after cotton has mixed
withthe air.
If wet cotton isfed intothe system, the air iscooled and the PRIMARY controllersignalsthe HIGH
LIMITcontroller that more heat is needed to compensatefor this cooling. The HIGH LIMIT controller operates
the burner's gas valve to supply this heat, but in no case will the temperature be permittedto exceedthe limit
whichthe ginner has previouslyspecified. If drycottonisfed intothe systemthe reverse occurs. Inthe case of
achoke
or large air leak, the HIGH LIMIT controller may not be able to contain the temperature within the
specifiedlimits and
it will then shut down the burner to prevent a fire (with an appropriate ERROR code on
burnerswith microprocessorcombustioncontrols).
NORM& OPERATIONPROCEDURE
There isaspring returnselector switchlocatedbelowthe PRIMARYcontrollerwith a "1" on the rightand a "0" on
the
left. These are symbolsfor START-STOPoperations. Turnthe switchto "1" andrelease itto start the burner.
Turnthe switchto
"0" to shut downthe burner. After turningthe switchto "l", pleasenotethat there isa preset
time delay to allowthe burner head and pipingto be purgedwith air. Followingthis delay, ignitionis triedand
shouldoccur immediately.
If ignition is not successful and your model has microprocessor combustion
controls, observe the STATUS lightto see
if it isflashing. If it is, go to the burner'scontrolcabinetand notethe
ERROR/AIARM code displayed on the localpanel. There is a decal at the controlcabinet and a page in each
servicemanual explainingthe numbers. It will be necessaryto pressthe RESET button on the burner's local
panelin orderto clearthe
ERROR andrestartthe burner. Inthe case of failure inignition or failure inoperation,
the burner will automatically attempt to restart itself for a maximum of three attempts. Neither digital
temperaturecontroller will come on untilflame has beenestablishedinthe burner. This isto preventthe highly
responsivecontrolsfrom "windingup"duringthe air purgedelaytime and causingthe burner to come on with a
roar. When they do energize, the controllers will take
12 seconds to perform self-check operationsand then
displaythetemperatures.
There are four temperatures displayed at all times during burner operation. The PRIMARY control on the
left
shows twoandthe HIGH LIMITcontrolon the rightshowstwoas well. The lowerdisplayonthe PRIMARYisthe
temperaturewhich the ginner sets and is the only one he will adjust under normal circumstances. It isthe
temperaturedesired after the mixpoint. It is raisedand loweredwith the orange buttons below it. The upper
displayshows the actual temperature being reported by the downstreamthermocouple. On the HIGH LIMIT
controller,the lower display is the temperature which the PRIMARY control is feeding it (See "Principle
of
Operation"Section). The upperdisplayon the rightisthe actualtemperaturebeforethe mixpoint. By observing
the upper display on both controllers,it is possibleto estimate the wetness of the incoming cotton as they
will
movefarther apart asthe cottongets wetter.

/90
17600 CONTROLINTERFACE OPTION
When the 17400 controlisusedwiththe 17600 Control InterfaceOption, it isnot necessaryfor the ginner to use
the arrow buttonson the PRIMARY controllerto adjust the desiredtemperaturedownstream. The PRIMARY
will
obtainthis value from the 17600 (whichiscoming from a GranberrySeries 800 Moisture Monitor). If the ginner
disagreeswith the suggested temperature coming from the 17600, he should use the arrow buttons on the
17600to adjust
it to his preference. Pressing the DOWN ARROW buttonon the 17600tells the control that he
desiresa lower cotton moisture content at the feeder apron and it will turn UP the temperature on the 17400
controlto achieveit. Pressingthe UP ARROW buttonworks inreversetothis.
If it isever desiredto bypassthe Series 800 andthe 17600 Control Interface,operatingthe burner with manual
setpointentry by the ginner can be done easily. Remove the button cover on the upper left button on the
PRIMARYcontrol. This isthe FUNC button. Pressingthis buttonwill tell the PRIMARY controller to ignorethe
incomingsignal from the 17600 (designated
"RSP on the lower display) and take its temperaturecommands
from the ginner. The new lower display will be designated "SP".
"RSP stands for Remote Set Point and "SP"
standsfor Set Point.
ADJUSTING THEMODULATING LIMIT
The modulating limit is the temperature before the mixpoint which the control is programed not to exceed.
Please note that the burner will not be killed,
it will simply not be allowedto go over this setting. This setting is
factorypreset at
350 F (176 C) as there is general agreement in the industrythat temperaturesinexcessof this
levelpermanentlydamage cottonfibers. The procedurefor changingthissettingfollows.
The programmingis done on the HIGH LIMIT controller. Remove the button covers on the lefthandtop and
bottombuttons. These are labelled FUNC and SETUP. First, unlock the controller by pressingSETUP 1time
and FUNC 4 times. LOCKOUT shouldbe displayed in the lower display. Press either ARROW button untilthe
upperdisplaysays NONE. Press LOWR DISP one timeto unlockthe control.
Now pressSETUP
5 times until INPUT2 isdisplayedinthe lowerdisplayarea. Press FUNC 2times untilIN2 HI
isinthe lowerdisplay. This isyour modulatinghighlimitvalue. Use the ARROW buttonsto set itat the desired
level. Please note that the controller will not operate correctlyif this value is set higher than 400 F (204 C)
or
lowerthan 200 F (93 C). PressLOWR DlSPto set the newvalue.
Relockthe control by repeatingthe above procedurebut pressingthe ARROW buttonsuntil MAX LOCKOUT is
displayed. Replacethe buttoncoverstodiscourageuse byunauthorizedpersonnel.
ADJUSTING THE CUTOFF SAFETY LIMIT
This limit is set on the HIGH LIMIT controller in a similar fashion to the modulating limit. Remove the button
coverson the lefthand top and bottom buttons. These are labelled FUNC and SETUP. First, unlock the
controllerby pressingSETUP one time and FUNC 4times. LOCKOUTshouldbedisplayedinthe lower display.
Presseither ARROW button until the upper display says NONE. Press
LOWR DlSP one time to unlockthe
control.
Now press SETUP
8 times untilALARMS is displayed in the lower displayarea. Press FUNC 1time untilAlSl
VAL is inthe lower display. This is your cutoff high limitvalue. Use the ARROW buttonsto set it at the desired
level. We recommend setting this value approximately 25-50 degrees
F above the modulating limit. Press
LOWR DlSPto set the newvalue.
Relock the control by repeatingthe above procedurebut pressingthe ARROW buttonsuntil LOCKOUT MAX is
displayed. Replacethe buttoncoversto discourageuse byunauthorizedpersonnel.

EXPLANATION OF ERROR AND ALARM CODES
H0-7-1114B/H0-4-1118
(FOR SOFIlwARE VERSIONS 2.2 AN.. LATER)
PRELIMINARIES -- As explained in the OperationNotesfor the 17400 Temperature Control, ERRORS will cause
theburner to shut down. ALARMS will permitthe burner to continueoperation, but will warn of conditionswhich
maybecome serious. In each case, a number
will be shown on the digital display inside the burner's control
cabinet. This numberwill refereitherto an ALARM or an E
R. The numberdisplayedwill bethe FIRSTalarm
or error to occur
in a five minutetime interval. This could that
an ALARM code isdisplayed, yet the burner
mayhaveshutdownduetoan ERROR.
* ERROR 20 -- AIR FLOWSWITCH NOT OFF IN 24 HOURS. The air flowswitchmustbeoperatedperiodicallyto
test itsproper operation. If the burnerandfans have runcontinuouslyfor over
24 hours,the burnerwill NOTshut
downdue to this ERROR However,
if the burner is turned off and an attempt isthen madeto restart it without
turning
off the fans, it will notstartandwilldisplay ERROR 20. The RESETbuttonwill NOTallowrestart. The fans
mustbeturned

ALARM 21 -- LOW AIR FLOW. This ALARM isan indicationthat a partialchoke of the air flow isoccurring. It is
displayedwhen the air flowswitchgoes
off andcomesbackon in lessthan 3 seconds.
ERROR 22 -- LOW AIR FLOW. The air flow was interruptedfor morethan 3 seconds. Verify proper air flowand
adjustswitch
if necessary.

when the fuel pumpwas off. Check the OLP tosee thatitscontactshave notbeenbridgedandthat it isadjusted
properly. Runthe test programtocheckitsadjustment.
ERROR 27 -- OIL PUMP RAN 20 MINUTES WITH OILVALVE SHUT. There is no oil return pipe on this burner.
Forthis reason, prolongedrunningof the fuel pumpwith the fuel valve shut can causeoverheatingof the fuel line
inthe lowercabinet.
ERROR 28 -- LOWATOMIZING AIR PRESSURE. The atomizingair pressurefell below 45 psi (3 bars). This may
becausedbyan inadequateair compressor,aclosedvalve inthe supplyline or an unusualusage of compressed
air elsewhere
in the plant. Dependableatomizingair pressureisessentialfor the proper operationof the burner.
The pressureshown on the air pressuregauge on the burner headshouldbe equalto the oil pressure, normally
about
60 psi(4.0 bars).
* ERROR 29 -- ATOMIZING AIR PRESSURE SWITCH NOT WORKING. In Step 5, the atomizing air pressure
switchAAP toldthe PLC that air pressurewas presentalthoughthe air valve had not beenopened. Check for a
leakingair valve or defectiveAAP.

ERROR AND ALARM CODE WLANATION
PG 2
ERROR 30 -- MODULATING MOTOR FAILS TO GO TO LOW FIRE. There is a limit switch indicatingwhen the
burneris
in the lowfire position. On dder units, this switch is insidethe motor. Now it isaseparatelimitswitch.
The PLC demandsthatthis switch
be ON in the lowfire positionand OFF asthe valve opens. If burnerthrottleis
inlow fire position, check lowfire switch adjustment.
If lowfire positionisnot attained, run the test programto
Step
5 and test the operationof the modulatingmotor MM. Check for proper voltage on terminalsL1 and L2 of
MM.
* ERROR 31 -- MODULATING MOTOR FAILS TO OPEN. This is similar to ERROR 30, and the same things
shouldbechecked.
ERROR 32 -- LOW COMBUSTION AIR PRESSURE. This error occurswhen the combustion air pressureswitch
CAP sees insufficientcombustion air pressureduring certain steps of the operating program. Check for proper
rotationof the combustionair fan motorM1, and makesure the overloadrelayMOLl for thismotorisnottripped.
Resetit with the white push button. After verifying good combustion air pressure (through the tubes goingto
CAP), checkfor properoperation
of CAP.
ERROR33 -- COMBUSTION AIR PRESSURE SWITCH NOT WORKING. In Step 13, the combustion air fan is
killedpriorto trialfor ignition. The pressuremust fall to 1" (25 mm) and turn
off combustionair pressureswitch
CAP within 15 seconds or this error
will be activated. Look for wrong adjustment of CAP or bridging of its
contacts.
ALARM 34 -- HIGH TEMPERATURE LIMIT TURNED BURNER DOWN. This alarm is valid only for combustion
controlsoftware versions prior to version
2.0. Its purpose is to give notice that the throttling valve is reducing
burneroutputinresponseto a hightemperaturecondition.

ERROR 36 -- EXCESSIVEFLAME FAILURES. The burnerwas shut down becausemorethanthree flame failures
(inignitionor operation) occurred after the burner was started. Normally,the burner will attemptto restartona
flame failure of any kind. If the lastflame failure occurredlessthan five minutesbeforethe shutdown, ALARM 37
or ALARM
38 maybedisplayedfor this ERROR.
ALARM 37 -- FLAMEWAS NOT ESTABLISHED. Step 15reachedthe endof itsmaximumtime, but flamewas not
established. Reset the PLC and startthe programagain. Lookfor a proper sparkthroughtheviewingport
in the
burnerbody oppositethe spark electrode. If you do not see a spark, look for oil on the spark igniter or wrong
adjustmentof the spark igniter. See drawing of proper clampingposition
of igniter. If you see a spark but no
flame, observethe oil flow meter for inadequateoilflow at low fire or air or water in the oil. If you see aflame in
theviewing window of the burner, but the flame light does not come on, we can suspect a defective UV Flame
DetectorMP or a defective Flame Relay FLR. Unscrew MP and test
it with a lightedmatch while watching input
light 15onthe PLC.
ALARM 38 -- FLAME FAILED DURING OPERATION. Flame was establishedthen failed. This can becausedby
air or water
in the oillineor atomizingair pressurehigherthan oil pressure.
ERROR 39 -- FLAME SIGNAL BEFORE FUEL BEFORE SPARK. This error is usually caused bytamperingwith
the FlameRelay FLR. Check to see thatthe contactsof FLR have notbeenbridgedorjammed.
ERROR 40 -- FLAME SIGNAL BEFORE FUEL DURING SPARK. This error is caused by the UV Flame Scanner
MP seeing the spark as a flame. Removethe scanner andverifythat the small orificedisk isinfront of the lens.
If
the diskisthere, the 3 mmholemayneedto be smaller.

PG 3
ERROR 41 -- FLAME STAYS TOO LONGAFTER SHUTDOWN. This error occurswhen flameisstillpresentatthe
endof Step
20, the toleratedafterburnperiod. Normally, one should stop the burneras described in Step 19 of
the operationsequence. Look at the flowmeter to see if the Fuel
Oil Valve FOV in the lower cabinet is closing
properly. See if

ERROR42 -- GAS LOW TEMPERATURE. This error is valid only for heaters equipped with the DUAL-FUEL
OPTIONto
burn bothoiland gas. It occurswhen a propanevaporizerfails and allowsliquidpropanetoreachthe
gas pipingof the burner. The lowtemperatureof the liquidpropanecauses the switchto open, killingthe burner,
andpreventinga fire.
ERROR 43 -- GAS LOW PRESSURE. This error isvalid only for heatersequippedwith the DUAL-FUELOPTION
to burn both
oil and gas. It occurs when gas pressure is too low for proper heater operation. Check all gas
supplyvalves toverify thatthey are openandcheckthe operationof the propanevaporizer.
ERROR 44 -- MISSING FAN INTERLOCK. This ERROR is caused when an attempt is madeto start the burner
when nofan interlock relayis present.
A fan interlockrelay issupplied with the 17400 remote controlto provide
instantshutdownof the burner when the fans are stopped. The installingelectricianisresponsiblefor wiring the
coilof thisrelayto thefan circuits.

The presence
of variousinputscanbeverifiedbyobservingthe numberedlightsatthe rightend of the heater's PLC.
INPUTSare atthe bottom. OUTPUTS are atthe top. The STEP NUMBERwill beshownon the LCD digitaldisplay
on the sequence panelSP.
STEP
0 -- After releasingRESETbutton,press it onceto proceed.
STEP
1 -- Observethe conditionof inputsoutlinedinTEST SEQUENCE. The operationof the remoteandlocalstart-
stopswitchesand other inputscanbetestedwhile observingthe inputLED'S. Turningthestart-stopswitchtothe
"1"
will test lights 1,2, andRemote Flame.
Press RESETto proceed.
STEP
2 -- Thisstepteststhe modulatingmotoronthe fuelvalve at the burnerhead. Inaddition, itteststhe electronic
drivefor the motor. Turningthe localstart-stopswitchtothe startpositionapplies20mA DC tothe drive, which
should openthe valve to thefull fire position. Releasingthe switchor turning
it tostopremovesthe DC currentfrom
the drive, whichshouldbringittothe lowfireposition. As the valve approachesthe lowfireposition,observeinput
light 11 (low fire switch)onthe PLCto makesure that itturnson onlyatthe lowfire position. The operationof the
lowfire switchLFSischecked bythe PLC duringthe preburnroutine.
As withthe combustionair switch,the PLC will
notpermitthe burnertostartunless
LFS operatesproperly. Adjustthe switchbyrotatingitscamonthe shaft.
PressRESETto proceedto Step
3.
STEP 3 -- The fuelpumpisstartedat thisstep. Verify thatthe motoristurning in the properdirection(indicatedby
thearrowonthe motor).
If not, killpowerandreversetwo of the leadsatthe motorstarter (assumingthatthe
combustionair fan motorisrunning
in the properdirection). Returnto thisstep inthetest program.
If thisisa new installation, it will benecessaryto purgethefuel line. Openthe cock atthe burnerheadandplacea

Observethe oilpressure, which normallyshouldbe
60 psi (4 bars)butmayberaisedas highas 80 psi (5.4 bars) if
youcannotget sufficient heatoutput in actualoperation. This pressuredeterminesthe maximumheatoutput of the
burner. If necessary, adjustthe pressurewith thefuel pressurereliefvalve FPR inthe lowercabinet. FPR has an
adjustingscrew underitscap.
The oillowpressureswitchOLP shouldturnOFFinputlight6onthe PLC when the pressure
falls below 45 psi (3
bars). Adjust OLP if necessary.
PressRESETtoproceedtoStep

STEP 4 -- Step 4 opensthe atomizingair valve. Adjustair pressureregulatorAPR so air pressureatthe gauge on
the burnerheadisequaltothe fuel pressure. Now, slowlyclosethe gate valve inthe air supplypipeto reducethe air
pressure. Atomizingair pressureswitchAAP shouldturnOFF inputlight8 onthe PLC when the pressurefalls below
45 psi (3 bars). AdjustAAP if necessary.
PressRESETto proceedto Step
5.
STEP 5 -- This stepwill startthe combustionair fan. Verify thatthe fan motoristurning in the properdirection(arrow
on fan motor).
If not, reverseanytwo leadsatthe maindisconnectswitchonthe sideof the controlcabinet. The
combustionair pressureswitchCAP has been adjustedto operateat a pressureof
1" (25 mm)pressure. Input 10 on
the PLC shouldbe
ON when thecombustionair fan is ON, andbeOFFwhen combustionair pressureisnot present.
Inthe operationsequence, the PLCteststhis switchfor Error
33. Ifthe switchisstuckclosed,the burnerwill not
start.
PressRESETto proceedtoStep

STEP 6 -- Startthe mainfan. Verify thatall pushand/or pullfans are runningintheproper directionandthatthereis
sufficientair flow. Ifthe heater isattachedto apushfan itmayneedto beisolated
or stabilizedto minimizevibration.
A flexibleconnectionto the pushfan ispreferred. Adjustthe air flowswitchAFS so PLC inputlight 5 showsitto be
ON withthe mainfans running.
Press RESETto proceedto step
7. (Input 5 and 3 mustbe ON.)
STEP 7 -- (Dual FuelOnly) Test gasvalves. Turnthe Start-Stopswitchtothe "1" (start)to openthe slow opening
gas safety shut-offvalve. Notethe readingonthe gas pressuregage locatedbetweenthe valves. Turn the Start-
Stopswitchtothe
"0 (stop)to closethe safety shut-offvalve and openthe pilotgasvalve. This exhauststhe gas
trappedinthe cavityandthe gage shouldnowread
0 PSI. If the gage showsa pressureincreasewhen neithervalve
isenergized, itisan indicationof a gas leak inthe safety shut-offvalve andshouldbecorrectedbeforeoperationof
the heater.
If the gage showsan pressuredecrease when neithervalve isenergized, it isan indicationof a gas leak
inthe maingasvalve or pilotvalve. Althoughthisisnotas serious
as aleakingsafetyshut-offvalve, the problem
doesrequirecorrection.
Adjustthe gas pressureat the regulatorto readapproximately
3.5 PSIusingthe methodjust described. The gas
pressureisadjustedbyunscrewingthe topcap of the gas pressureregulatorand, usinga
1 /2 driveon a socket
wrench, turningthe adjustmentclockwiseto increasethe pressureandcounterclockwisetodecrease
it.
