This chapter explains how to establish alarm set points,
autotune and manually tune and establish cascade con­trol through the Operations Page of the software.

To configure the alarm outputs, go to the Setup Page of
the software (see related information in the Parameters
Chapter).

For the alarm clearing procedure, go to the Troubleshoot­ing Alarms and Errors table in the Navigation and
Operating from the Front Panel Chapter.

For background information about alarms; proportional,
integral and derivative control; and cascade, see the Fea­tures Chapter.

Alarm Set Points

The Series F4P includes two alarm outputs, which can be
programmed as process, deviation or rate 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. Rate alarms are triggered by a change in
temperature or process value that is faster than the se­lected rate.

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 value that,
if exceeded, will trigger an alarm. This value 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 value that, if
exceeded, will trigger an alarm. This value must be lower
than the alarm high set point and higher than the low
limit of the sensor range.

The Alarm Low Deviation defines the deviation value
on the low side of set point at which the alarm will be
triggered.

The Alarm High Deviation defines the deviation value
on the high side of set point at which the alarm will be
triggered.

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

Autotune PID

In autotuning, the controller automatically selects the
PID parameters for optimal control, based on the ther­mal response of the system. In the Series F4P, five sets of
PID values are available. 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.

Set point changes for remote, ratio and differential con­trol are ignored until autotuning is complete.

Autotuning Procedure

Autotuning is initiated from the Operation Menu.

1. Before initiating auto-tune, go to the System Menu
(Setup Page), and establish the Autotune Set Point
to a percentage of set point. 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.

Select to display Tune Status in the Custom Main
Page Menu.

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

3. Go to the Autotune PID Menu (Operations Page) and
choose the PID set in which to store the values. You
must exit back to Main Page with the left arrow. A
message will be displayed on the Main Page during
the autotuning process.

4. When autotuning is complete, the controller will
store the values for optimum control in the specified
PID set.

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

✔ Note: While the controller is autotuning, only the Op-
eration Page of the software can be entered.

ç

CAUTION: Choose an autotune 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 autotune set point very
carefully to prevent product damage.

Edit PID

The Edit PID Menu 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.

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.

For background information, see Chapter 7, Features.

Manual Tuning Procedure

1. Apply power to the Series F4P and establish a set
point on the Main Page.

2. Establish Cycle Time in the Control Output Menu
(Setup Page), as required. Typical cycle times are 1.0
second for an SSR and 5.0 seconds for a mechanical
relay. Faster cycle times sometimes achieve the best
system control. However, if a mechanical contactor or
solenoid is switching power to the load, a longer cy­cle time may be desirable to minimize wear on the
mechanical components. Experiment until the cycle
time is consistent with the desired quality of control.

3. Go to the Edit PID Menu (Operations Page), and
choose the channel and PID set. Establish values for
the PID parameters: Proportional Band, 5; Integral
(Reset), 0; Derivative (Rate), 0; and Autotune, Tune
Off. Tuning begins when you choose a PID set.

4. When the system stabilizes, watch the value of Input
1 on the Main Page. If this value fluctuates, increase
the proportional band setting 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).

Watlow Series F4P Operations Page ■ 3.3

6. Start with an integral setting of 99.9 minutes and al­low 10 minutes for the process temperature to get 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.

7. Increase Derivative/Rate to 0.10 minute. Then in­crease the set point by 11° to 17°C. Watch the sys­tem's approach to the set point. If the process value
overshoots the set point, increase Derivative/Rate to

0.50 minute.
Increase the set point by 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 over­shoot or sluggishness.

For additional information about the burst fire feature,
manual tuning and PID control, see the Features Chapter.

Multiple PID Sets

Environmental chambers, ovens and furnaces typically
have different thermal requirements at high and low
temperatures or pressures. To accommodate this, the Se­ries F4P can store five different PID sets.

Multiple Tuning Procedure

To autotune multiple PID sets, follow the Autotuning
procedure above for each PID set. When autotuning is
finished for one set, proceed with another.

Cascade

Cascade control is available on enhanced (F4P _ - _ _ AB

- _ _ _ _) Series F4P 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 inner loop set point,
Process Cascade uses Low and High Range settings that
are independent of set point; Deviation Cascade uses De­viation Low and High settings that are deviations from
the primary set point.

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.

3.4 ■ Operations Page Watlow Series F4P

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.

This chapter explains how to configure the controller
software through the Setup Page menus. Setup Page pa­rameters affect the way the controller responds to your
application, which parameters and functions are visible
in other pages, and the way information is displayed on
the Main Page. Set up the controller properly to provide
a sound foundation for settings in other pages.

For ranges, defaults and other information about specific
parameters, see the Parameters Chapter. Record your
settings in the Parameter Setup Record, also in that
chapter.

For background information about inputs, outputs,
alarms and other features, see the Features Chapter.

Parameter Setup Order

Initial configuration of the Series F4P is best done in the
following order:

1. Go to the System Menu (Setup Page) to configure:

• PID units — SI (Integral, Derivative) or U.S. (Re­set, Rate);

• Celsius or Fahrenheit scales;

• display of units in the controller’s upper display;

• Autotune set point;

• open-loop detection warnings; and

• controller response to a power outage.

2. Go to other menus on the Setup Page to configure:

• Analog Input x (1 to 3);

• Digital Input x (1 to 4);

• Control Output x (1A, 1B);

• Alarm Output x (1 or 2);

• Retransmit Output x (1 or 2);

• Communications; and

• Custom Main Page and Custom Messages.

3. Go to the Operations Page to tune the PID sets.

4. Go to the Operations Page to set the alarm set
points.

After this initial configuration, the most frequent
changes will be to the Operations Page (alarm set points
and PID sets).

If the Series F4P is already installed in an environmen­tal chamber, oven, furnace or other equipment, most pa­rameters will already be configured and access to the
Setup Page may be limited (see Chapter 5, Factory
Page).

Changing Setup Page parameters may change other pa­rameters. In some cases, a change in one parameter will
affect the defaults of others. To see how all the pages,
menus and parameters are grouped, see the software
map on the inside back cover of this manual.

✔ Note: For more information about how parameter set-
tings affect the controller’s operation, see the Features
Chapter.

çWARNING: Only authorized and qualified personnel

should change the factory-default settings, which may
cause changes in other settings. Failure to comply with
this recommendation may result in damage to equipment
and property and injury to personnel.

Security

The Series F4P allows users to set separate security
levels for the Static Set Point prompt on the Main Page,
for all menus on the Operations Page, as well as for the
Setup Page and Factory Page. Four levels of security are
available:

• Full Access (operators can enter and change
settings);

• Read Only (operators can read but not change
settings);

• Password (operators can enter and change settings
after entering a password); and

• Hidden (operators cannot see the menu or page — it
is not displayed). Set Point settings cannot be
Hidden.

✔ Note: Full Access is the default for all menus. Unless
you change the level of access, operators will be able to
read and change every setting in every menu in the
Series F4P software.

How to Set Lockout Levels

Diagnostics

Diagnostic Menu parameters (on the Factory Page)
provide information about the controller unit that is
useful in troubleshooting. For example, the Out1A
parameter will identify what type of output has been
selected for Output 1A.

Select the parameter by pressing the Right Key . . The
information will appear on the Lower Display.

Some of the parameters in the Diagnostic Menu provide
information for factory use only.

To reset all parameters to their original factory values,
use the Full Defaults parameter under the Test Menu.

Test

This menu allows you to test outputs, test the displays
(upper, lower and status lights), and cause the controller
to revert to the defaults set at the factory. Reverting to
factory defaults will erase all preset software and the
controller will return to U.S. PID units (Reset and Rate)
and the Fahrenheit temperature scale.

Calibration

Pages, Menus and Parameters

The Series F4P parameters are arranged into four
groups, or pages: Main; Operations, Setup and Factory.
See the chapters about each page for additional informa­tion. The Features Chapter provides information about
features, such as alarms, and the parameters that apply
to them.

Only active parameters will appear on the controller. If,
for instance, Output 1B is set to Off, no other output 1B
parameters will appear.

Changing some parameters will force changes to other
parameter settings. The safest and most efficient way to
configure the Series F4P controller for the first time is to
configure the parameters in the Setup Page in the order
in which they appear.

It may also be helpful for you to make copies of the Pa­rameter Records for each of the pages, as well as the
Custom Main Page Record, then record your settings for
future reference.

✔ Note: If the Series F4P is already installed in an oven,
furnace or other equipment, most parameters will already be
configured and access to the Setup Page may be limited
(locked).

✔ Note: To see how all the pages, menus and parameters
are grouped, see the software map on the inside back cover
of this manual.

✔ Note: For more information about how parameter settings
affect the controller’s operation, see the Features Chapter.
