Overview

Andy, an engineer with the Ajax
Testing Company, is running tempera­ture and humidity tests on navigation­al equipment. He wants to be able to
control temperature and humidity in
the environmental chamber, and moni­tor the temperature of the equipment
itself. With the Watlow Series F4 ramp­ing controller, he can:

•program the test as a ramping profile
and control it remotely;

•use boost heat and cool to maintain
precise temperatures;

•record the equipment temperature on
a chart recorder;

•notify the operator with a bell if pro­cess temperatures do not follow the
profile;

•pause the profile if someone opens the
chamber door during the test;

•set up communications with a PC
later.

5. Run the Profile

Andy pressed the Profile Key and
selected the test profile. He monitored
the progress of the test on the display
and the equipment temperature on the
chart recorder.

See the Operations Chapter.

1. Wire

Following diagrams in the user manual, Andy
connected the analog input terminals to temper­ature and humidity sensors, channel 1 output
terminals to the heater and cooler, channel 2
outputs to the humidifier/dehumidifier, alarm
output 1 to an alarm bell and retransmit output
1 to a chart recorder to track the equipment
temperature. Digital output 6 and 7 controlled
the boost heater and cooler, and 8 controlled the
mechanical refrigeration compressor.

See the Wiring Chapter.

Watlow Series F4S/D Introduction ■ 1.3

This sample application is continued in the Operations, Profile Programming and Setup Chapters.

Main Page___________

3. Customize and Name

Andy customized the Main Page so he could
tell the status of the digital outputs by glanc­ing at the controller's Lower Display (Setup
Page > Custom Main Page Menu).

He also named one of the Alarms "TEMP
DEV", which will make it easy to identify the
alarm condition (Setup Page > Alarm Output
1 Menu). Three digital inputs, two alarms
and eight digital outputs can be given 10­character names.

See the Setup Chapter.

4. Program the Profile

Andy programmed the test as a ramping pro­file of 21 steps. To make sure the equipment
is at the ambient chamber temperature, he
put a Wait condition on Step 2. Step 20 is a
Jump step that puts the equipment through
the same heat and humidity cycle 21 times.

See the Profile Programming Chapter.

✔ NOTE:
The profile in this sample application is embedded
in the Series F4 software for use as a teaching tool
or a template. It is the first profile, MILSTD810D,
located in the Profiles Page > Edit Profile Menu.
You can change or delete this profile and later
recall it through factory defaults. If you have a
single-channel controller, you will see only the tem­perature on Channel 1. This is not the true
Military Standard Test 810D.

2. Set up the F4

After checking the navigation instructions
in the user manual, Andy went to the
Setup Page of the software to configure the
controller for the equipment and the ramp­ing profiles. He named the alarm to make
it easier to identify an alarm condition. The
alarm message will appear on the Lower
Display, which also informs about the
progress of the test.

Overview

This chapter introduces the user interface of the
Series F4S/D controller — the displays, keys and
indicator lights, and the principles of navigating
the software to program profiles and change setup
settings. The Series F4 is designed with user­friendly features to facilitate setup, programming
and operation of the Series F4.

The four-line LCD display facilitates setup and
programming, and presents informative messages
about status, error and alarm conditions.

Digital inputs, digital outputs, profiles and alarms
can be named for easy reference.

The Information Key summons information about
the pages, menus, parameters and values, as well
as error and alarm conditions if they occur.

The software is organized into five pages of menus.
The Main Page gives access to the other four —
Operations, Profiles, Setup and Factory. The Main
Page can be customized to display user-chosen
information.

Series F4S/D Operation

The Series F4S/D controller can function as either

a static set point controller or as a profile con-
troller. The information shown on the Lower Dis­play during operation (the Main Page) is pro­grammable and can be customized to support both
modes of operation. (See Setup Page.)

In either the static set point mode or the profile
mode, the Series F4 can only be operated in a
closed-loop configuration. Manual operation (open­loop) mode is not allowed.

Static Set Point Control

The Series F4 is in static mode when it is not con-

trolling a ramping profile. When in static mode:

• The Profile Indicator Light is off.

• The Upper Display shows the actual process
temperature of input 1, 2 or 3 depending upon
Setup Page configuration.

✔

NOTE:

All control activity stops when you enter the Setup Page,
Analog Input, Digital Input, Control Output, Alarm Out­put, Retransmit, and Digital Output menus.

• The Lower Display shows the default or user­configured information set. See the Setup
Chapter for instructions in programming the
Main Page to display the information you want.

To operate the Series F4 as a static set point con­troller, use the navigation keys (><,.) to
select the preferred channel and adjust the set
point.

Limits may be placed on the set point in the Set
Point Low Limit and Set Point High Limit parame­ters (Setup Page > Analog Inputx).

Setting the set point to Set Point Low Limit minus
1 (-1) will turn control Output 1 off and display the
set point as off.

ç WARNING

Check the configuration of the controller on the Setup
Page before starting and running a profile (if the Setup
Page is not locked). Make sure the settings are appropri­ate to the profile: input sensor ranges and limits, digital
inputs and outputs as events, guaranteed soak band, re­sponse to power out and Celsius or Fahrenheit scales. If
the Setup Page is accessible, failure to check the configu­ration before running a profile could result in damage to
equipment and/or property, and/or injury or death to per­sonnel.

Profile Control π

The main purpose of the Series F4 is to control pro­files for ramp-and-soak-processing applications.
The instructions below explain how to use an exist­ing profile. To program a profile, see Chapter 4,
Profile Programming.

As a protective measure, all stored profiles will be cleared
if you enter the Setup Page and change values in the
Analog Input 1, 2, 3 menus —specifically, the Sensor,
Sensor Type, Decimal, Scale (for process inputs), and Set
Point High and Low Limits. Pop-up messages will warn
that the profiles will be erased from the controller’s mem­ory.

✔

NOTE:
You must configure the software for your inputs and out­puts before programming a profile. See the Setup Chap­ter.

✔

NOTE:
You must program a profile or use the pre-programmed
MILSTD810D profile before running it. See the Profile
Programming Chapter.

✔

NOTE:
While a profile is running, the controller will not recog­nize digital inputs that are programmed to start a profile.
Such digital inputs will be recognized only while the con­troller is in the static set point mode.

3.4 ■ Operations Watlow Series F4S/D

Alarm Set Points

The Series F4 includes two alarm outputs, which
can be programmed as process or deviation alarms.

Process alarms notify the operator when process
values exceed or fall below Alarm Low and Alarm
High Set Points. Deviation alarms notify the opera­tor when the process has deviated from the set
point beyond the deviation limits. For more infor­mation, see the Features Chapter. To set up the
alarms, see the Setup Chapter.

Alarm set points are the points at which alarms
switch on or off, depending on the alarm setting.
Alarm set points can be viewed or changed in the
Alarm Set Point Menus (Operations Page).

The Alarm High Set Point defines the high tem­perature that, if exceeded, will trigger an alarm.
This temperature must be higher than the alarm
low set point and lower than the high limit of the
sensor range.

The Alarm Low Set Point defines the low tem­perature that, if exceeded, will trigger an alarm.
This temperature must be lower than the alarm
high set point and higher than the low limit of the
sensor range.

✔

TIP:

You may want to set up the alarms with names that will
identify the alarm conditions. See the Setup Page.

To Clear an Alarm or Error

In an alarm condition, an alarm message will ap­pear on the Main Page (if this option has been se­lected on the Setup Page). To silence it, move the
cursor to the alarm message and press the Right
Key . . Apop-up message will confirm the silenc­ing of the alarm, and the indicator light will go off.

When the condition causing the error or alarm is
corrected, return to the error or alarm message on
the Main Page, and press the Right Key again. A
pop-up message confirms the alarm is unlatched.

Auto-tune PID

In autotuning, the controller automatically selects
the PID parameters for optimal control, based on
the thermal response of the system. In the Series
F4, five sets of PID values are available for each
channel of the controller: sets 1 to 5 for channel 1,
and sets 6 to 10 for channel 2. Default PID values
exist for all PID sets, although these values typi­cally do not provide optimal control. PID values
can be auto-tuned or adjusted manually. When au­totuning is complete, the PID values will be stored
in the Edit PID Menu.

✔

NOTE:
PID Set 1 for Channel 1 and PID Set 6 for Channel 2
are used in the Static Set Point mode.

Autotuning Procedure

Autotuning cannot be initiated while a profile is
running. It can only be initiated in the static set
point control mode.

1. Before initiating auto-tune, go to the System

Menu (Setup Page), and set the Channel 1 or 2
Autotune Set Point to the percentage of set point
you choose to begin with. This percentage is
based on your knowledge of the system and how
much overshoot or undershoot there is likely to
be in on-off control.

In the Custom Main Page, select to display Tune
Status 1 and Tune Status 2. This displays Tune
Status in the Main Page.

2. Go to the Main Page and set the static set point.

3. Go to the Autotune PID Menu (Operations Page)

and choose the channel to auto-tune and the PID
set in which to store the settings. Amessage will
be displayed on the Main Page during the auto­tuning process. (Auto-tune cannot be initiated
when a profile is running. It can only be initiated
in the static set point mode.)

4. When autotuning is complete, the controller will

store the values for optimum control in the PID
set specified.

✔

NOTE:
While the controller is autotuning, profiles cannot be run
and only the Profiles Page and Operation Page of the
software can be entered.

ç

CAUTION: Choose an auto-tune set point value that will
protect your product from possible damage from overshoot
or undershoot during the autotuning oscillations. If the
product is sensitive, select the auto-tune set point very
carefully to prevent product damage.

For additional information about autotuning and proportion­al, integral and derivative control, see the Features Chapter.

Edit PID

Edit PID is useful when Auto-tune PID does not
provide adequate control. Each of the PID parame­ters can be adjusted manually:

Proportional Band: Define a band for PID con­trol, entered in degrees or units. Lower values in­crease gain, which reduces droop but can cause os­cillation. Increase the proportional band to elimi­nate oscillation.

Watlow Series F4S/D Operations ■ 3.5

Integral (Reset): Define the integral time in min­utes per repeat; define reset in repeats per minute.
Set repeats per minute if units are U.S.; minutes
per repeat if units are SI.

Derivative (Rate): Define the derivative (rate)
time in minutes. Large values prevent overshoot
but can cause sluggishness. Decrease if necessary.

Dead Band: Define the dead band in degrees or
units. Heating dead band shifts the set point down.
Cooling dead band shifts the set point up. For more
information, see the Features Chapter.

Manual Tuning Procedure

1. Apply power to the Series F4 and enter a set
point. Go to the Operations Page, Edit PID Menu
and begin with Proportional Band set to 5; Inte­gral (Reset) set to 0; Derivative (Rate) set to 0;
and Autotune set to Tune Off.

2. Start manual tuning by entering the desired set
point and let the system stabilize. Once the sys­tem stabilizes, observe the value of Input 1 on
the Main Page. If the Input 1 value fluctuates,
increase the proportional band setting until it
stabilizes. Adjust the proportional band in 5º to
10º increments, allowing time between adjust­ments for the system to stabilize.

3. Once Input 1 has stabilized, observe the percent
power on the Main Page. It should be stable,
±2%. At this point, the process temperature
should also be stable, but it will exhibit droop
(stabilized below set point). The droop can be
eliminated with reset or integral.

4. Start with a reset setting of 0.01, and allow 10
minutes for the process temperature to come up
to set point. If it has not, increase the setting to

0.05 and wait another 10 minutes. After this,
double the reset setting and wait another 10
minutes until the process value equals the set
point. If the process becomes unstable, the reset
value is too large. Decrease the setting until the
process stabilizes.

5. Increase Derivative/Rate to 0.10 minute. Then
raise the set point by 20° to 30°F, or 11° to 17°C.
Observe the system's approach to the set point. If
the load process value overshoots the set point,
increase Derivative/Rate to 0.50 minute.

Raise the set point by 20° to 30°F, or 11° to 17°C
and watch the approach to the new set point. If
you increase Derivative/Rate too much, the ap­proach to the set point will be very sluggish. Re­peat as necessary until the system rises to the

new set point without overshooting or approach­ing the set point too slowly.

For additional information about manual tuning
and proportional, integral and derivative control,
see the Features Chapter.

Multiple PID Sets

Environmental chambers, ovens and furnaces typi­cally have different thermal requirements when
they operate at high and low temperatures or pres­sures. To accommodate varying thermal require­ments, the F4 is capable of storing five different
PID sets for each channel. One set for each channel
can be chosen in each profile step.

For example, a controller in an environmental
chamber with PID settings optimized for control at
subzero temperatures may not control well when
the set point is set to temperatures above the boil­ing point of water. With the F4, one PID set could
be used for subzero operation and another set for
temperatures above boiling.

Multiple Tuning Procedure

1. To auto-tune a single PID set, begin by setting
the static set point on the Main Page.

2. Go to the Autotune PID Menu (Operations Page),
and choose a channel and a set. Autotuning be­gins when you select the set. The Main Page dis­plays information about the autotuning process
when Tune Status is selected in the Custom
Main Page.

3. When autotuning is finished, proceed with
another PID set.

In the example above, the user would first auto­tune a PID set for subzero operation, and then an­other for operation at boiling temperatures. When
programming a profile, the user could then select a
different PID set for each step, depending on the
thermal requirements.

✔

NOTE:

Autotuning cannot be done while running a profile. It can
only be initiated when the controller is in the Static Set
Point Control mode.

3.6 ■ Operations Watlow Series F4S/D

Cascade

Cascade control is available on the Series F4 con­trollers. For background information about cascade
control, see the Features Chapter.

Select cascade control through the Analog Input 3
Menu (Setup Page) and choose Process Cascade or
Deviation Cascade. To set the range for the Process
Cascade Inner Loop set point, use Low and High
Range settings. These are independent of the Chan­nel 1 set point. Deviation Cascade uses Deviation
Low and High settings that are referenced to the
Channel 1 set point.

Deviation Cascade is used in applications with large
set point ranges or where limiting heating or cooling
equipment temperatures is required.

When tuning a cascade system, the inner loop must
be tuned first. The inner loop comprises outputs 1A
and 1B and the Analog Input 1 sensor, which usually
measures the energy source temperature. The output
device controls a power switching device, which in
turn switches the heating and cooling. The set point
for the inner loop is generated by the outer loop. For
Process Cascade, this will have a range between the
Cascade Low Range and Cascade High Range.

Cascade Setup Procedure

1. First, configure Analog Input 3, Cascade Low
Range and Cascade High Range.

Go to the Analog Input 3 Menu (Setup Page).
Choose Process or Deviation Cascade. Deviation
Cascade references Channel 1 set point allowing a
range above and below the current control set
point. For Process Cascade control of a heat/cool or
cool only system, set the Cascade Low Range to a
value slightly lower than the lowest temperature
desired in the chamber. For heat-only systems, set
the Cascade Low Range to a value slightly lower
than the ambient temperature; otherwise the heat
output will never turn fully off.

For heat/cool or heat only systems , set the Cas­cade High Range to a value slightly higher than
the highest temperature desired in the chamber.
For cool-only systems, set the Cascade High Range
to a value slightly higher than the ambient tem­perature; otherwise the cooling will never fully
turn off.

2. Next, configure the controller to tune and display
data for the outer loop. To view Inner Loop Set
Point in the upper display, go to the Setup Page,
Custom Main Page Menu, select the Inner Set
point as one of the parameters, P1 to P16, to be
displayed in the Main Page.

To also view Analog Input 3 in the upper display,
go to the Setup Page, Process Display Menu, and
choose Alternating. Under Set Display Time,
choose a duration for the display of the Input 1 and
Input 3 variables.

Cascade Autotuning Procedure

1. Go to Setup Page, Custom Main Page Menu.
Choose Tune Status 1 and Tune Status 2 to ap­pear as 2 of the 16 parameters that can be dis­played on the Main Page. The Main Page will now
display the status of the autotuning process.

2. Autotune the inner loop. Go to the Autotune PID
Menu (Operations Page), and select Cascade In­ner-loop. Choose Cascade Inner Loop PID Set 1 to
5, where PID values will be stored after autotun­ing. Autotuning begins when you choose the PID
set. While autotuning, the F4 controller will con­trol the energy source in an on-off mode to a tem­perature equal to the Cascade High Range setting
x Channel 1 Autotune Set Point. For best results,
use proportional control only on the inner loop.

3. Next, autotune the outer loop. Go to the Auto­tune PID Menu (Operations Page). Choose
Cascade Outer Loop, then choose Outer Loop PID
set 1 to 5, where PID values will be stored after
autotuning. Autotuning begins when you choose
the PID set. While autotuning, the outer loop will
be controlled in an on-off mode at a set point
equal to static set point x Ch 1 Autotune Set
Point. In most cases, the autotuning feature will
tune for acceptable control. If not, manually tune
the outer loop (step 4 below). Before manually
tuning, record the values generated by the auto­tuning feature.

4. To manually tune the outer loop, go to the Edit
PID Menu (Operations Page). Choose Cascade
Outer Loop, then choose Outer Loop PID set 1 to

5. Begin manual tuning by setting the Propor­tional Band to 5, Integral (Reset) to 0, and Rate
to 0. Establish the desired set point and let the
system stabilize. When the system stabilizes,
watch the Inner Loop Set Point on the Main
Page. If this value fluctuates, increase the pro­portional band until it stabilizes. Adjust the pro­portional band in 3° to 5° increments, allowing
time for the system to stabilize between adjust­ments.

5. When Input 1 has stabilized, watch the percent
power on the Main Page. It should be stable,
±2%. At this point, the process temperature
should also be stable, but it will exhibit droop
(stabilized below set point). The droop can be
eliminated with Integral (reset).

6. Start with an integral setting of 99.9 minutes,
and allow 10 minutes for the process tempera­ture to come up to set point. If it has not,
decrease the setting by half and wait another 10
minutes. Then halve the setting again and wait
another 10 minutes until the process value
equals the set point. If the process becomes
unstable, the integral value is too small. Increase
it until the process stabilizes.

Andy, an engineer with the Ajax Testing Company,
is running temperature and humidity tests on
navigational equipment. He runs the test profile,
Military Standard Test 810D, having already set
up the controller and programmed the profile.

In Step 4, the temperature in the chamber exceed­ed the Alarm 1 setting. This triggered the alarm,
causing the indicator light on the front panel (next
to the bell-shaped icon) to light up and a message
to appear on the lower display: "TEMP DEV
High."

Because Alarm 1 was set up as a latching alarm
(Setup Page), Andy had to clear it manually. First
he corrected the alarm condition by widening the
gap between low and high deviation alarm set­tings on the Operations Page. He then unlatched
the alarm by returning to the Main Page alarm
line and pressing the Right Key . again.

If your Series F4 is a single-channel controller,
you will see only the temperature on Channel 1.
This is not the true Military Standard Test 810D.
