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.

Inputs

Multiple Input Offsets

Offset point are used to compensate for differences be­tween the target process value and the sensor value read
by the Series F4P. Multiple offset points enable the F4P
to compensate for non-linear differences between the sen­sor readings and target process values over the thermal
or process system operating range. Sensor reading differ­ences can be caused by sensor placement, tolerances, an
inaccurate sensor or lead resistance.

The Series F4P controller supports both single point and
multiple point offsets. The choice for single or multiple
offsets is made in the Setup Page > Analog Input Menu.

A single point offset allows the F4P to control the process
to one offset value difference linearly either above or be­low the sensed value over the entire operating range.

Multiple point offsets allow the Series F4P to control the
process to 10 different offset points over the operating
range. Each offset point has a programmable positive or
negative offset value. Offset points can be positioned any­where over the operating range. Offset point values are
programmable between -1,000 and +1,000. Offset values
are linearly interpolated between the nearest two offset
points. Offset values are added to the sensed value to es­tablish a target process value. Offset Point 1 is pro­grammable as the first point or low end point of the
range. Offset points 2 through 10 follow sequentially. Off­set values lower than the first point (point 1) or higher
than the last point (point 10) are zero.

Filter Time Constant

A time filter smoothes an input signal by applying a
first-order filter time constant to the signal. Either the
displayed value or both the displayed and control values
can be filtered. Filtering the displayed value makes it
easier to monitor. Filtering the signal may improve the
performance of PID control in a noisy or very dynamic
system.

A positive value affects only the viewed values. Anega­tive value affects both the viewed and control values.

Watlow Series F4P Features ■ 7.3

Set Point Low Limit and High Limit

The controller constrains the set point to a value between
a low limit and a high limit. The high limit cannot be set
higher than the sensor high limit or lower than the low
limit. The low limit cannot be set lower than the sensor
low limit or higher than the high limit.

7.4 ■ Features Watlow Series F4P

High Scale and Low Scale

When an analog input is selected as a process input, you
must choose a value to represent the low and high ends
of the current or voltage range. For example, if an analog
input with a process sensor type 4 to 20mA is selected,
then 0 could represent 4mA and 100 could represent
20mA. The set point will be limited to the range between
scale low and scale high.

Location in software: Setup Page > Analog Input and
Setup Page > Retransmit Output x (1 or 2).

Scaling

When an analog input is selected as a process input, you
must choose the scaling relationship of the current or
voltage input signal to the Low Scale and High Scale pa­rameters.

For example, with Normal Scaling selected, Scale Low =
0, and High Scale = 100 for a 4 to 20mA input, 0 repre­sents 4mA and 100 represents 20mA. With Scale Inver­sion selected, the Scale Low value represents a 20 mA in­put signal and Scale High represents a 4 mA input sig­nal.

The value entered for Scale Low must be less than the
Scale High value with Normal Scaling or Inverse Scaling
selected.

Location in software: Setup Page > Analog Input and
Setup Page > Scaling.

Digital Inputs

With a digital input an operator can perform certain op­erations on a system by opening or closing a switch or
applying a dc logic signal to the controller. This feature
can add convenience, safety or security to a system.

In the Series F4P, digital inputs 1 to 4 can be assigned to
display messages, switch to another set point or perform
other process control features.

A low or high state will trigger an event for as long as
that state exists. Arising edge will turn on an event
when it changes from a low to a high state. The event
will continue until the rising edge (low to high state) oc­curs again.

Watlow Series F4P Features ■ 7.5

Control Methods

Auto (closed loop) and Manual (open
loop) Control

Auto (closed loop) control uses a process sensor to deter­mine the difference between the process value and the
set point. Then the controller applies power to a control
output load in order to reduce that difference.

Manual (open loop) control allows the user to directly set
and adjust the power level to the control output load.

The Series F4P Auto/Manual Indicator Light is on when
the controller is in manual mode. The controller can only
switch between auto and manual mode from the Main
Page. To toggle between manual and auto mode, first
press the å key, then confirm your selection in the lower
display. The indicator light will flash after you press the
å key until you confirm your choice or 10 seconds have
elapsed.

In manual mode, the user manually adjusts the output
power level. Changes take effect when the new value has
been entered and the controller is back in the Main Page.

Before it switches from manual to auto mode the F4P
checks to make certain a functioning sensor is connected
to analog input 1.

The user can select how the Series F4 determines a set
point when it makes a transition from manual to auto op­eration. It can automatically switch back to the last set
point it used in auto mode or use reverse bumpless trans­fer, which will establish a set point that equals the pro­cess value at the time it was switched from manual
mode.

Location in software: Setup Page > System.
The user can protect the process being controlled by se-

lecting the maximum control output power levels that
will be allowed when the controller switches from auto to
manual power.

Location in software: Setup Page > System > Maximum
Heat Transfer Power and Maximum Cool Transfer Power.

7.6 ■ Features Watlow Series F4P

On-Off Control

On-off control switches the output either full on or full off,
depending on the input, set point and hysteresis values.
The hysteresis value indicates the amount the process
value must deviate from the set point to turn on the out­put. Increasing the value decreases the number of times
the output will cycle. Decreasing hysteresis improves con­trollability. With hysteresis set to 0 the process value
would stay closer to the set point, but the output would
switch on and off more frequently, causing “chattering.”

Set the proportional band to 0 to set the controller to on­off control mode.

Page > Edit PID > PID Set x (1 to 5).

✔

NOTE:

Fail power does not function in on-off control mode.

Figure 7.6a — On-Off Control for Heating and Cooling.

Proportional Control

Some processes need to maintain a temperature or pro­cess value closer to the set point than on-off control can
provide. Proportional control provides closer control by
adjusting the output when the temperature or process
value is within a proportional band. When the value is in
the band, the controller adjusts the output based on how
close the process value is to the set point; the closer to
set point the lower the output. This is similar to backing
off on the gas pedal of a car as you approach a stop sign.
It keeps the temperature or process value from swinging
as widely as it would with simple on-off control. However,
when a system settles down, the temperature or process
value tends to “droop” short of the set point.

With proportional control the output power level equals
(set point minus process value) divided by propband.

Proportional Integral Derivative (PID)
Control

Use derivative control to minimize overshoot in a PI-con­trolled system. Derivative adjusts the output based on
the rate of change in the temperature or process value.
Too much derivative will make the system sluggish.

Location in software: Operations Page > Edit PID > PID
Set x (1 to 5).

Figure 7.7b — PID Control.

Dead Band

In a PID application the dead bands above and below the
set point can save an application's energy and wear by
maintaining process temperature within acceptable
ranges. Shifting the effective cooling set point and heat­ing set point keeps the two systems from fighting each
other.

Proportional action ceases when the process value is
within the dead band. Integral action continues to bring
the process temperature to the set point. When the dead
band value is zero, the heating element activates when
the temperature drops below the set point, and the cool­ing element switches on when the temperature exceeds
the set point.

Location in software: Operations Page > Edit PID > PID
Set x (1 to 5).

Figure 7.7c — Cooling Dead Band.

Proportional plus Integral (PI) Control

The droop caused by proportional control can be correct­ed by adding integral control. When the system settles
down the integral value is tuned to bring the tempera­ture or process value closer to the set point. Integral de­termines the speed of the correction, but this may in­crease the overshoot at startup or when the set point is
changed. Too much integral action will make the system
unstable. Integral is cleared when the process value is
outside of the proportional band.

Integral (if units are set to SI) is measured in minutes
per repeat. Alow integral value causes a fast integrating
action.

Reset (if units are set to U.S.) is measured in repeats per
minute. Ahigh reset value causes a fast integrating ac­tion.

7.8 ■ Features Watlow Series F4P

Multiple PID Sets

The Series F4P supports up to five heat/cool PID sets.
This feature is extremely valuable if the characteristics
of your thermal system vary over its operating range. All
PID sets can be auto tuned or manually tuned. PID sets
can be edited in the Operations Page. The Series F4P can
be programmed to operate using any of the five sets
based on crossover points of the set point or process val­ue. These programming choices are made in the Opera­tions Page > PID Crossover.

When the process or set point value crosses the crossover
point, the PID set designated for that region of the oper­ating range is used to control the percent power being
supplied to the load.

There is a -1° hysteresis for each crossover. Arising tem­perature will change PID sets at the crossover value. A
falling temperature will change PID sets at the crossover
value -1°.

Location in software: Operations Page > Edit PID > PID
Crossover x (1 to 4).

Figure 7.8a — Multiple PID Sets.

Burst Fire (variable-time base)

Burst firing provides even output power with the lowest
level of noise generation (RFI). Burst fire is the preferred
method for controlling a resistive load, providing a very
short time base for longer heater life.

The controller determines when the ac sine wave will
cross the 0-volts point, then switches the load on or off
only at this point, minimizing RFI.

Other Features

Autotuning

The autotuning feature allows the controller to measure
the system response to determine effective settings for
PID control. When autotuning is initiated the controller
reverts to on-off control. The temperature must cross the
auto-tune set point four times to complete the autotuning
process. Once complete, the controller controls at the nor­mal set point, using the new parameters. The F4P stores
the value in the PID set specified.

Location in software: Operations Page > Autotune PID >
PID Set x (1 to 5).

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, carefully select the auto-tune set
point to prevent product damage.

Figure 7.9 — Autotuning.

✔ NOTE:
For manual tuning, see the Operations Chapter.

Retransmit

Retransmit outputs 1 and 2 can retransmit an analog
signal to serve as an input variable for another device.
The signal may serve as a remote set point for another
controller or as input for a chart recorder to document
system performance over time.

Location in software: Setup Page.

Open Loop Detect

Open loop checks the integrity of the control loop, con­sisting of the controller output, power control, heater and
sensor.

If the output power is at its maximum for a period of
time equal to the reset time and the input has not
changed at least ± 5°F, the controller will switch to Man­ual Mode at 0% output power. The upper screen will dis­play [oPLP`] and the lower screen will display “Open
Loop.”

To clear an open loop error, after correcting the problem
that caused it, turn the controller off then back on.

Alarms

Alarms are activated when the process value or tempera­ture leaves a defined range. Auser can configure how
and when an alarm is triggered, what action it takes and
whether it turns off automatically when the alarm condi­tion is over.

Configure alarm outputs in the Setup Page before setting
alarm set points.

Alarm Set Points

The alarm high set point defines the process value or
temperature that will trigger a high side alarm. It 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 temperature that
will trigger a low side alarm. It must be lower than the
alarm high set point and higher than the low limit of the
sensor range.

Location in software: Operations Page > Alarm Set Point
> Alarm x (1 or 2).

Alarm Hysteresis

An alarm state is triggered when the process value
reaches the alarm high or alarm low set point. Alarm
hysteresis defines how far the process must return into
the normal operating range before the alarm can be
cleared.

Alarm hysteresis is a zone inside each alarm set point.
This zone is defined by adding the hysteresis value to the
alarm low set point or subtracting the hysteresis value
from the alarm high set point.

Location in software: Setup Page > Alarm Output x (1 or

2).

Figure 7.10 — Alarm Settings.

Process, Deviation or Rate Alarms

A process alarm uses one or two absolute set points to
define an alarm condition. Adeviation alarm uses one or
two set points that are defined relative to the control set
point. High and low alarm set points are calculated by
adding and/or subtracting offset values from the control
set point. If the set point changes, the window defined by
the alarm set points automatically changes with it.

A rate alarm is triggered by a change in temperature or
process value that exceeds the selected rate.

Alarm Latching

A latched alarm will remain active after the alarm condi­tion has passed. It can only be deactivated by the user.
An alarm that is not latched (self-clearing) will deacti­vate automatically when the alarm condition has passed.

Location in software: Setup Page > Alarm x (1 or 2).

Figure 7.11a — Alarm Latching.

Alarm Silencing

Alarm silencing has two uses:

1. It is often used to allow a system to warm up after it
has been started up. With alarm silencing on, an
alarm is not triggered when the process temperature
is initially lower than the alarm low set point. The
process temperature has to enter the normal operat­ing range beyond the hysteresis zone to activate the
alarm function.

2. Alarm silencing also allows the operator to disable
the alarm output while the controller is in an alarm
state. The process temperature has to enter the nor­mal operating range beyond the hysteresis zone to
activate the alarm output function.

If the Series F4P has an output that is functioning as a
deviation alarm, the alarm is silenced when the set point
is changed, until the process value re-enters the normal
operating range.

Location in software: Setup Page > Alarm x (1 or 2).

Alarms can be configured to trigger when the process ex­ceeds the High Alarm Set Point, the Low Alarm Set
Point or both.

Advanced Features

Boost Heat and Boost Cool

Boost operation is supported on output 1B. Boost is en­abled when outputs 1A and 1B are configured to perform
the same function: heat/heat or cool/cool.

The type of boost operation chosen in the output 1B
menu can be either boost on power or boost on set point.

When boost on power is selected, output 1B is turned on
or off based on the output load power requirements.
Boost on power can be enabled for operation in the auto
mode only or in both the auto and manual mode. If cho­sen, the power level at which output 1B will be turned on
is set in the Operations Page > Control Set Points. Ade­lay time can also be set. The delay time will delay the
turn on of the boost output until the power level is
exceeded for the time of the delay. There is a 5% power
level hysteresis between boost on and boost off operation.

When boost on set point is selected, output 1B is turned
on or off based on a programmable set point value or on a
deviation from the set point value. Boost set points and
boost deviation values are set in the Operations Page >
Control Set Points.

Watlow Series F4P Features ■ 7.13

Duplex

Certain systems require that a single process output con­trol both heating and cooling outputs. ASeries F4P con­troller with a process output in output 1A (F4P _ - F _ A
A- _ _ _ _) can function as two separate outputs.

With a 4 to 20mA output the heating output, for in­stance, will operate from 12 to 20mA (0 to +100%) and
the cooling outputs will operate from 12 to 4mA (0 to ­100%). In some cases this type of output is required by
the device that the Series F4P controls, such as a three­way valve that opens one way with a 12 to 20mA signal
and opens the other way with a 4 to 12mA signal. This
feature reduces the overall system cost by using a single
output to act as two outputs.

Digital Set Points

Up to four nameable digital set points can be configured
to control the Series F4P outputs. Each of the Series
F4P’s four digital inputs can be configured to select a dif­ferent set point value.

When the digital set point function is selected in the Dig­ital Input Menu, an adjustable digital set point value pa­rameter (with the default name of “Dig. SPX”) will be
displayed in the Operation Menu > Control Set Points.

When the selected digital input goes to its true condition
(which is determined on the Setup Page) the Series F4P
will control to the enabled digital set point value. The en­abled digital set point value and name will replace the lo­cal set point displayed on the Main Page. This set point
is not adjustable from the Main Page.

Only one digital set point can be enabled at a time. If
more than one digital input is configured as a digital set
point, priority will be based on the order scanned by the
Series F4P.

The enabled digital set point remains enabled for as long
as the digital input is in its true condition. When no digi­tal set points are enabled, control in the closed-loop mode
will revert to the local set point value.

Watlow Series F4P Features ■ 7.15

Remote Set Point

The Series F4P with the enhanced control option can be
configured to support up to two remote set points. This
feature allows the closed-loop, process set point to be
changed remotely.

In remote set point operation the measured process val­ue of the remote set point input is used as the control set
point in closed-loop operation. Analog inputs 2 and 3 can
be configured as remote set point inputs. Remote set
point (Remote 2 and Remote 3) values are limited in
range to the operating range of the sensor selected for
analog input 1, unless the operating range of the remote
set point input sensor is less than the operating range of
input 1. If that is the case, the remote set point sensor
operating range will be used.

The switch to a remote set point input as the control set
point can be made with a digital input or by selection in

the Operations Menu. Remote set point operation is
masked if it is not enabled in the analog input 2 and 3
menus. Remote set point operation has priority over local
set point operation when selected by one of the four digi­tal inputs.

Location in software: Setup Page > Analog Input x (2 or

3) and Setup Page > Digital Input x (1 to 4).

Alternate Control

The Series F4P with the enhanced control option can be
configured to have analog input 1 or analog input 2 func­tion as the sensor input for closed-loop control. This fea­ture can be used to support the need for redundant sen­sor operation or where sensor location or sensor type
changes can improve process control.

The transition between inputs is made through the oper­ation of the designated digital input. To ensure proper
control operation the sensor used for analog inputs 1 and
2 must be the same. The linearization type can be differ­ent. Example, a K thermocouple can be used on input 1
and a J thermocouple can be used on input 2. The deci­mal value and unit type follows the input 1 selection.

The Series F4P firmware considers the sensor not being
used to be off. Out-of-operating-range transitions will
cause the Series F4 to switch to the manual mode. Tran­sitions from outside the set point operating range will

cause the control set point to go to either the low or high
set point limit, which ever is closer.

The alternate input option is only available in normal
control operation. The remote set point and digital set
point features are not available when alternate input op­eration is enabled.

7.16 ■ Features Watlow Series F4P

Cascade

Cascade control is a control strategy in which one control loop
provides the set point for another loop. It allows the process
or part temperature to be reached quickly while minimizing
overshoot. Cascade is used to optimize the performance of
thermal systems with long lag times.

This graph illustrates a thermal system with a long lag time.
Curve Arepresents a single-loop control system with PID pa­rameters that allow a maximum heat-up rate. Too much ener­gy is introduced and the set point is overshot. In most sys­tems with long lag time, the process value may never settle
out to an acceptable error. Curve C represents a single-con­trol system tuned to minimize overshoot. This results in un­acceptable heat-up rates, taking hours to reach the final val­ue. Curve B shows a cascade system that limits the energy
introduced into the system, allowing an optimal heat-up rate
with minimal overshoot.

Cascade control uses two control loops (outer and inner) to
control the process. The outer loop (analog input 3) monitors
the process or part temperature, which is then compared to
the set point. The result of the comparison, the error signal,
is acted on by the settings in a Cascade Outer Loop PID set
(1 to 5), which then generates a power level for the outer
loop. The set point for the inner loop is determined by the
outer-loop power level and the Cascade Low Range/Deviation
and the Cascade High Range/Deviation settings for analog in­put 3.

The inner loop (analog input 1) monitors the energy source
(heating and cooling), which is compared to the inner loop set
point generated by the outer loop. The result of the compari­son, the error signal, is acted on by the settings in a Cascade
Inner Loop PID set (1 to 5), which generates an output power
level between -100% to +100%. If the power level is positive
the heat will be on; if the power level is negative the cool will
come on.

In Series F4 controllers, cascade control is available on chan­nel 1. Analog input 3 is used to measure the outer-loop pro­cess while analog input 1, the inner loop, is used to measure
the energy source. Power from the energy sources are sup­plied by outputs 1A and 1B.

To set up and tune a system for cascade control, see the Oper­ations Chapter.

Watlow Series F4P Features ■ 7.17

Differential Control

The Series F4P with the enhanced control option can be
configured to support differential control. Differential
control allows the Series F4P to control one process at a
difference to another process.

Analog input 3 is configured as the differential input.
The process value measured on input 3 is added to the
differential value [Set Diff.] to become the closed-loop
control set point [CTL SP]. Four additional differential

values (Dgt. Diff. Value) can be enabled remotely through
designated digital inputs. The nameable digital differen­tial values are entered in the Operations Menu > Control
Set Points.

Differential control is only available in enhanced control
operation. Changes to the differential value or Analog In­put 3 during auto-tune are not acted on until the auto­tune process is completed or aborted.

Location in software: Setup Page > Analog Input 3 and
Setup Page > Digital Input x (1 to 4).

Ratio Control

The Series F4P with the enhanced control option can be
configured to support ratio control, which is especially
useful in applications that mix materials.

Analog input 3 is configured as the ratio input. The pro­cess value measured on input 3 multiplied by the ratio
value [Set Ratio] becomes the closed loop control set
point [CTL SP]. Four additional ratio values (Dgt. Ratio
Value) can be enabled remotely through designated digi-

tal inputs. The nameable digital ratio values are entered
in the Operations Menu > Control Set Points.

Ratio control is only available in enhanced control opera­tion. Changes to the ratio value or analog input 3 during
auto-tune are not acted on until the auto-tune process is
completed.

Slidewire Control

The Series F4P with the enhanced control option can be
configured to support slidewire valve control. In
slidewire control a closed-loop process value, is measured
at analog input 1 and compared to the control set point.
The difference between the measured value and the con­trol set point generates an error signal which is acted on
by PID to generate a percent output. The percent output
generated by PID is compared to the slidewire resistance
measured at analog input 3 to determine if the valve
needs to be closed or opened to decrease the difference
between the closed loop process value and set point.

Two, time-proportioned outputs are required to control
the valve position. Control output 1A is used to close the
valve and output 1B is used to open the valve. Output 1A
can be configured as heat (reverse) acting or cool (direct)
acting. With output 1A set to cool (direct) the valve will
open as the process value increases and power in the
manual mode will be adjustable from 0% to 100%. With
output 1A set to heat (reverse) the valve will close as the
process value increases and power in the manual mode
will be adjustable from 0% to +100%.

With PID generating a 25% output, output 1A set to cool
(direct), a slide-wire resistance range of 100 to 1200
ohms and slidewire resistance measured on analog input
3 is greater than 275 ohms (25% of span) output 1B will
be on opening the valve to increase the cooling effect to
decrease the process value until the measured resistance
equals 25% of span. With the same conditions and the
measured resistance less than 275 ohms (25% of span)

output 1A will be closing the valve to decrease the cool­ing effect until the measured resistance equals 25% of
span.

To select slideware control, set Analog Input 3 > Sensor
to Slidewire. The slidewire feature can be calibrated ei­ther automatically or manually.

Fine tune the behavior of the slidewire control using the
Hunt and Hysteresis parameters, in Setup Page > Ana­log Input 3 > Slidewire.

Watlow Series F4P Installation and Wiring ■ 8.3

Installing the Series F4P Controller

Installing and mounting requires access to the back of
the panel.

Tools required: one #2 Phillips screwdriver.

1. Make the panel cutout using the mounting template
dimensions in this chapter.

2. Insert the controller into the panel cutout. Check
that the rubber gasket lies in its slot at the back of
the bezel. Slide the retention collar over the case,
with open holes facing the back of the case.

3. Align the mounting bracket with the screws tips
pointed toward the panel. Squeezing the bowed sides
of the bracket, push it gently but firmly over the case
until the hooks snap into the slots at the front of the
case.

4. If the installation does not require a NEMA 4X seal,
tighten the four screws with the Phillips screwdriver
just enough to eliminate the spacing between the
rubber gasket and the mounting panel.

For a NEMA 4X seal, tighten the four screws until
the gap between the bezel and panel surface is .020
inch maximum. (See figure 3c). Make sure that you
cannot move the controller back and forth in the
cutout. If you can, you do not have a proper seal. Do
not overtighten. Overtightening could damage the
the mounting bracket.

Figure 8.3a — Gasket Seated on the Bezel.

Figure 8.3c — Tightening the Screws.

8.4 ■ Installation and Wiring Watlow Series F4P

Removing the Series F4P Controller

The controller can be removed most easily by disengaging
the mounting bracket hooks and pushing the controller
forward through the panel. Be ready to support it as it
slides forward through the panel.

Tools required: one #2 Phillips screwdriver, one flat-head
screwdriver and some means of supporting the controller
as it slides out the front of the panel.

1. Remove all the wiring connectors from the back of
the controller. Using the Phillips screwdriver,
unscrew the four screws on the mounting bracket
(two on top, two on bottom) until the tips are
completely retracted into the shafts.

2. Slide the tip of a flat screwdriver between the case
and the center top side of the mounting bracket.
Rotate the screwdriver 90 degrees, stretching the
bracket away from the case so the hooks on the
bracket disengage from the slots on the case. Hold
the bracket and press the controller forward slightly
to prevent the disengaged hooks from snapping back
into the slots.

3. Repeat this operation to disengage the hooks on the
bottom side of the mounting bracket.

4. Press with one or two fingers on the lower half of the
back of the unit so that the controller slides forward
through the panel. Hold the bracket steady; do not
pull back. Be ready to support the controller as it
comes through the front panel. Remove the mounting
brackets and retention collar from the back side of
the panel.

Figure 8.4 — Disengaging the Mounting Bracket.

Watlow Series F4P Installation and Wiring ■ 8.5

Wiring the Series F4P

Wiring options depend on the model number, which is
printed on the label on the back of the controller. The
model number codes are explained in the Appendix.

The labels on the sides and back of the controller contain
some basic wiring information.

Input-to-Output Isolation

The Series F4P uses optical and transformer isolation to
provide a barrier to prevent ground loops when using
grounded sensors and/or peripheral equipment.

Here is a breakdown of the isolation barriers:

• Analog input 1 and all the digital inputs are grouped
together.

• Analog inputs 2 and 3 are grouped together.

• All the control outputs and retransmit outputs are
grouped together.

• Both alarm outputs are grouped together.

• Communications is isolated from the other inputs
and outputs.

Figure 8.5a — Isolation Blocks.

ç

WARNING: Provide a labeled switch or circuit breaker
connected to the Series F4P power wiring as the means of
disconnection for servicing. Failure to do so could result
in damage to equipment and/or property, and/or injury or
death to personnel.

Figure 8.5b — Power Wiring.

Sensor Installation Guidelines

Thermocouple inputs: Extension wire for
thermocouples must be of the same alloy as the
thermocouple to limit errors.

If a grounded thermocouple is required for input 2, the
signal to input 3 must be isolated to prevent possible
ground loops.

RTD input: Each 1Ω of lead wire resistance can cause a
+2°F error when using a two-wire RTD. Athree-wire
RTD sensor overcomes this problem. All three wires must
have the same electrical resistance (i.e., same gauge,
same length, multi-stranded or solid, same metal).

Process input: Isolation must be maintained between
input 2 and input 3. If both input 2 and input 3 are
process signals, a separate power supply and transmitter
must be used for each input. These inputs must be
electrically isolated from one another to prevent ground
loops.

ç

CAUTION: If high voltage is applied to a low-voltage unit,
irreversible damage will occur.

∫

WARNING: To avoid damage to property and equipment,
and/or injury of loss of life, use National Electric Code
(NEC) standard wiring practices to install and operate the
Series F4P. Failure to do so could result in such damage,
and/or injury or death.

8.6 ■ Installation and Wiring Watlow Series F4P

ç

WARNING: To avoid
damage to property and
equipment, and/or injury
or loss of life, use
National Electric Code
(NEC) standard wiring
practices to install and
operate the Series F4P.
Failure to do so could
result in such damage,
and/or injury or death.

ç

CAUTION: Maintain
isolation between analog
inputs 2 and 3, and
between analog input 1

8.12 ■ Installation and Wiring Watlow Series F4P

Communications Wiring

Figure 8.12a — EIA/TIA 485 and EIA/TIA 232 Communications

Figure 8.12b — Termination for EIA-232 to EIA-485 Converter

If the system does not work properly, it may need termination resistors at each
end of the network. Atypical installation would require a 120-ohm resistor
across the transmit/receive terminals (12 and 13) of the last controller in the
network and the converter box or serial card. Pull-up and pull-down 1k ohm
resistors may be needed on the first unit to maintain the correct voltage during
the idle state.

Exception Responses

When a controller cannot process a command it returns an exception response and sets the
high bit (0x80) of the command.

0x01 illegal command
0x02 illegal data address
0x03 illegal data value

Watlow Series F4P Communications ■ 9.1

The Series F4P uses Modbus as its communications pro­tocol. Modbus is a standard protocol developed by A.E.G.
Schneider. Modbus RTU enables a computer or PLC to
read and write directly to registers containing the con­troller’s parameters. With it you can read all of the con­troller’s parameters with a few read commands.

If you already have a software application that uses
Modbus, the Modbus Registers Table in this chapter will
provide the register number and values (sometimes
called enumerated types) for each parameter.

Dependencies between parameters do exist. For best re­sults, program the parameters in the order in which they
appear in the Software Map (inside back cover).

For basic information about writing an application using
Modbus protocol, you may want to download the elec­tronic F4P Communications Guide from the Watlow web
site: http://www.watlow.com/prodtechinfo. Search on the
key words Data Communications.
