It is not necessary to remove the control chassis from
the housing for installation. If the control chassis is
removed from the housing, you must follow industry
standard practice for control and protection against
Electro-Static Discharge (ESD). Failure to exercise
good ESD practices may cause damage to the control.

Rev. 10/98 5 949-1239-3
INPUT SELECTION
Before removing the instrument from its housing, make sure you take
appropriate precautions to avoid electro-static discharge (ESD). See
caution on opposite page. To change the input type, remove the instru-
ment from its housing by grasping the front bezel sides and pulling
forward to release it from
the housing lock.
Locate the dip switch on
the right pcb. Determine
the input type desired and
change the dip switch
setting as shown at the
right.
Reinstall the instrument
into the housing.
After changing input selec-
tion with the DIP switches,
be sure to change the InP
menu item (page 11) in the
Secure Menu.

LOGIC JUMPER SELECTION
Instruments with SSR or RELAY type outputs can be changed to and from a
LOGIC output in the field.
CAUTION: Damage to the instrument may result from an
incorrectly installed jumper strip. Follow the instructions
carefully. Damage to the instrument may also result from
improper handling. Use appropriate precautions to avoid
Electro-Static Discharge (ESD).
1. Remove the instrument from its housing. Grasp the front bezel sides and
pull forward to release it from the housing lock.
2. Locate the desired logic jumper strip on the left printed circuit board. The
OUTPUT A jumper
strip is always lo-
cated near the top
edge
3. To remove the logic
jumper strip, carefully
insert a small flat
blade screwdriver be-
tween the retaining
clip and the jumper
at one end of the
jumper strip. Apply slight pressure to
move the clip away from the jumper end
until it is released, then lift it up and out of
the clip.
4. To re-install the jumper strip, hold it with the spring contacts in the desired
position. Face springs up for SSR or RELAY outputs, or face springs down
for LOGIC outputs. Insert one end of the jumper strip under the retaining
clip and press the other end down until the remaining clip engages the
jumper.
5. To avoid any damage, recheck the jumper installation and the housing rear
terminal panel output wiring.

NOTATION CONVENTIONS FOR THE MENUS
Because of the number of features available in this control, information is
includedthatmaynotapplytoyourspecificcontrol. All usablefeaturesare
included in this book, but may not be used in your process. To increase
clarity the following conventions are used:
1. Certainfeatures,MenuItems,andfunctionsshowninthis bookmayor
maynotappearonyourcontrol,depending onotherMenuItemselections.
At various places in the Menus there are notes identifying Menu Items that
"control" or "direct" other menu items. If you are looking for a particular
menu item and can't find it, check the menu item that is its "control" for
proper setting.
2. The "#" symbol is used in two ways. It is used inside a group of
characters to indicate which set point function (SP1 or SP2) is being
affected. It is also used before a group of characters of a menu item to
indicate that there may be more than one selection or value for that menu
item.
3. Features that apply only to Options will be printed in Italics.
THE HOME DISPLAY
The home display is the normal display while the control is operating. If no
errors or functions are active, the HOME display will indicate the Process
Variable(thetemperature,pressure,flow,RH,etc.,thatisbeingmeasured)
on the top display and the Set Variable (Set Point 1) on the bottom.
ItemsthatcanchangetheHOMEdisplayaretheAuto/Manualfunction,the
Prog function, the PctO function, and any error message. Description of
these special displays follow.
If Auto/Manual Menu Item is On, the home display is changed. The upper
displaycontinuestoshowtheProcessVariable (PV), but the lower display
changes to show the percentage of output in tenths of a percent to 99.9%
(0.0 to 99.9), or 100 if 100%. The display digit to the right of the number

OPERATION OF SELF TUNE®FUNCTION
Self Tune®allows automatic selection of the necessary parameters to
achieve best control operation from your 1600 Series control. If you are
using the control output as a simple on-off function (S#Ot set for OnOF),
none of the following will apply.
Theory of Operation
The Self Tune function calculates the Pb1, rES, and rtE parameters under
thePIDtunEselectionasshownintheSecondaryMenu. Thesevaluesare
determined by measuring the response of the process connected to the
control. When Self Tune is started, the control temporarily acts as an on-
off control. While in this mode the control measures the overshoot and
undershootoftheprocess,andtheperiodoftheprocess(thetimefrompeak
value to the next peak value). These measurements are collected over a
period that lasts three periods of overshoot and undershoot. The data
collected over this time is then compared and calculated into final PID
values. The calculations for the PID values are the same as used in the
standardZiegler-Nicholsequationsthathavebeenrecognizedasstandard
for decades.
The only modification to the application of the Ziegler - Nichols equations is
controlled by the dFAC menu item. This menu item controls the amount of
rate(derivative)that is applied. AdFAC settingof 3(factorydefault)orless
allows for less damping. A dFAC setting of 4allows for critical damping as

949-1239-3 12 Rev. 10/98
set forth in Ziegler - Nichols. A dFAC setting of 5or more allows over
damping of the process.
Program Setup and Operation
In the secondary menu set tunE to SELF. Skip LErn and check to make
surethatdFAC isset tothedesired value. BackuptoLErnandsettoYES.
The control will begin the Self Tune function. While the Self Tune function
is active, the right hand decimal point on the lower display will blink. When
Self Tune is complete, the blinking will stop.
After the initial Self Tune is complete, the instrument will look at the LErn
menu item to determine if you wish to have the process continually tuned.
Setting LErn to Cont will allow the control to periodically check the tuning
parameters. Ifyouwishtohavethetuningvalueslockedin,setLerntoEnd.
If you wish at any time to view the PID values, change the tunE setting to
PID. Thisallowsexaminationand/ormodificationofthevaluescalculated.
We recommend that you do not change the calculated values unless you
haveafirmunderstandingoftheparametersinvolvedandtheirfunction. For
more information on PID tuning, please contact your supplier.
METHOD FOR SET UP OF A HEAT / COOL CONTROL WITH SELF
TUNE
Determine if the process is predominantly heating or cooling. An extruder,
for example, is predominantly cooling when running product. An environ-
mental chamber can be either heating or cooling.
Iftheprocessispredominantlycooling,setS1St todirand S2SttorE. Ifthe
process is predominantly heating, set S1St to rE and S2St to dir. Redirect
SP1 to output A or B as required by the hardware (see SP1o). Set S2t to
dE. Set SP2 for zero (no overlap of bands, no deadband). Set Pb2 to a
desired value (default is 12°F). Set tunE to SELF, Strt to YES, and LErn
to End.
Starttheprocessandwaitforittocometostability. Occasionallycheckthat
theSelfTunehascompletedthelearningprocessbyINDEXingtoStrtinthe
secondarymenu. IftheYESvaluehaschangedtono,thentheprocesshas
been learned. Once learning is complete, you may adjust SP2 to either
overlap the SP1 band (SP2 value less than zero), or add some separation
(or dead band) between them (SP2 greater than zero). Adjust SP2 as
required to optimize control.

Rev. 10/98 13 949-1239-3
PROGRAMMING AND OPERATION
FOR RAMP / SOAK FEATURE
Theramp/soakfeatureoffersagreatdealofflexibilitybyallowingchanges
in the set point to be made over a predetermined period of time.
Theory of Operation
The 1600 Series controls offer a very simple approach to programming a
ramp. Rather than requiring the operator to calculate an approach rate
(usually in degrees per minute), the 1600 does the calculation internally.
Thus, the operator only needs to program the target set point, the time
desiredto reachthatpoint,andthetimedesiredtoholdatthatpoint. When
therampsegmentisexecutedbythecontrol,itcalculatestheramprequired
to move the process from the starting value (current PV) to the desired
value (programmed SP) in the time allowed.
Care must be taken, however, that the process does actually reach the
soak value before the soak time starts. Make sure to test any program for
desired results before running production material.
Do not operate Self Tune while a ramp function is operating. The
ramp function will prevent the Self Tune from operating properly.
Make sure that all tuning is set up before operating Ramp / Soak.
Program Setup
The programming for the Ramp / Soak function is done in the Secondary
Menu.
In the Secondary Menu INDEX to Prog and make sure that Prog is set to
OFF.
Skip the StAt setting (this is discussed later) and press INDEX to 1rt.
Set 1rt to the amount of time you want for the ramp. This value is in time
units from 00.01 to 99.59 (hh,mm). Press INDEX.
Set 1St to the amount of time you want for the soak. This value is in time
units from 00.01 to 99.59 (hh,mm). Press INDEX.
Thelastmenuitemfortheramp/soakfunctionisPEnd. PEnddetermines
what the control does when the program has ended. You may choose to
Hold the set point (SP1), or turn the outputs off (OoFF).

Ramp / Soak Operation
Whenyouwishtostarttheprogram,entertheSecondaryMenuandsetthe
Prog menu item to On. Return to the HOME position by waiting for the
display to time out or by pressing the UP ARROW / ENTER keys and then
the DOWN ARROW / INDEX keys.
Changing the AUTO / MANUAL menu item to Auto OFF will also suspend
the program operation. This also puts the control into manual mode.
Auto / Manual Control
Manual Control is enabled through the Secondary Menu. When Auto is
turnedOn,thelowerdisplay in the HOMEpositionwilldisplaytheoutput in

SP1 appears first with a flashing “o”on the right hand corner of the lower
display to represent percent. Press INDEX to display SP2 output. A
flashing "õ" will appear on the right hand corner of the lower display to
represent percent.
When Manual is enabled, the present control outputs are held (bumpless
transfer) and displayed. The output for SP1 or SP2 can then be manually
adjusted while displayed by pressing the UP ARROW or DOWN ARROW
key to change the value, and then the ENTER key to activate.
The Upper display will normally indicate the Process Value. Since Manual
will override most fault messages the upper display could indicate a fault
message. Refer to the Diagnostic Error Message Section for further
explanation.

nor PID values are preset for a normal response process.
FASt PID values are preset for a fast response process.
Pid2 Linkage of PID parameters between SP1 and SP2: Select On or
OFF.
On Links SP2 to SP1 or #SP1 rEs and rtE terms for heat/
cool applications.
OFF Sp2 functions without rEs and rtE.
ArUP Anti- Reset Wind-up Feature: Select On or OFF.
On When ArUP is On the accumulated Reset Offset value

the Proportional Band.
OFF When ArUP is OFF, the accumulated Reset Offset
Value is retained in memory when the process input is
not within the Proportional Band.
ArtE Approach Rate Time: Select OFF, 0.01 to 99.99 minutes. The
function defines the amount of Rate applied when the input is
outside of the Proportional Band. The ArtE time and the rtE
time are independent and have no effect on each other. To
increase damping effect and reduce overshoot set the approach
rate time for a value greater than the natural rise time of the
process (natural rise time = process value time to set point).
Fint Fuzzy Logic Intensity(942): Select 0 to 100%. 0% is OFF
(disables Fuzzy Logic). The function defines the amount of
impact Fuzzy Logic will have on the output.
Fbnd Fuzzy Logic Error Band(942): Select 0 to 4000 °F, 0 to 2222°C,
or 0 to 4000 counts. Sets the bandwidth of the Fuzzy Logic. Set
Fbnd equal to PID proportional band (Pb1) for best results.
FrtE Fuzzy Logic Rate of Change(942): Select 0.00 to 99.99°F/sec.,
0.00 to 55.55°C/sec., or 0.00 to 99.99 counts/sec. For best initial
setting, find the degree/sec change of process value near set
point 1 with output ON 100%. Multiply this value by 3. Set FrtE
to this calculated value.

SP2. If your control is not equipped with a second set point, no SP2
functions will appear. The appearance of CY#,SP#d, or PUL# is
dependent upon the output type selected in the Secure Menu item S#Ot.
If time proportioning (cycle time) was selected, then CY# is adjustable. If

the menu indexes directly to S#Ot.
CY# Cycle Rate: Select 2 to 80 sec. Time Proportioning Control is
adjustable in 2 sec. steps. For best contact life, a time should be
selected as long as possible without causing the process to
wander.
SP#d Set Point On-Off Differential. Select 1 to 1999 deg. or counts.
When adjusting SP#d keep in mind that SPL and SPH have to be
considered to avoid a CHEC error message.
PUL# Pulsed Time Proportioning Output: Select 1to 7. 1 = Linear and
7 = most non-linear. Changes output linearty for use in cooling
applications or for an extremely fast response processes. At the
