Sample Application: Environmental Testingwith a Dual Channel F4 Using Multiple Inputs and OutputsOverviewAndy, 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.
1. WireFollowing 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.

2. Set up the F4After 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. See the Keys, Displays and Navigation Chapter. See the Setup Chapter.
3. Customize and NameAndy 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.

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.

Series F4S/D OperationThe Series F4S/D controller can function as either a static set point controller or as a profile controller. 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. ? 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. Static Set Point1___ ___ °F ▲▼ Adjusts Value < Back > Next 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. Static Set Point1___ OFF ▲▼ Adjusts Value < Back > Next
Static Set Point ControlThe Series F4 is in static mode when it is not controlling 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.

To Start/Run a ProfileTo initiate the profile mode, press the Profile Key π and answer the questions that follow. While running a profile, the Profile Status message on the lower display will keep you informed about the progress of the profile. For example, it could read like the screen at right:? NOTE: 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. ? NOTE: While a profile is running, profiles can be either created or renamed only while a profile is running. All other pages and menus can be entered only during Static Set Point Control mode.
? WARNINGCheck 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.

To Hold a Running Profile1. Press the Profile Key π while running a profile. The Profile Action Menu appears. 2. Choose to Don’t Hold, Hold or Terminate the profile. (Default is to Don’t Hold.) If you choose to hold the profile, the Main Page reappears, and the Profile Status message reads “Profile X holding.” The Profile Indicator Light is off. If you do not make a choice when the Profile Action Menu appears, the profile continues running and the profile indicator light stays on. Hold Profile:_______ Don’t Hold >Hold Terminate
? NOTE: While profiles are on hold, the step set point value can be adjusted using the Static Set Point parameter on the Main Page.
To Resume a Profile on Hold1. Press the Profile Key π while a profile is holding. The Resume Pro

file Menu appears. 2. Choose to Continue Holding, Resume or Terminate the profile. If you do not make a choice, the profile continues holding and the Profile Indicator Light stays off.
Resume Profile:_____ >Continue Holding Resume Terminate? NOTE: When a profile is resumed during a Ramp step, the controller uses the Static Set Point from the Main Page to calculate the rate of change needed to get to the set point at the end of the step. When a profile is resumed in a soak step, the new set point value will be used as the soak value for the time remaining in the step.

Alarm Set PointsThe 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.
? NOTE: PID Set 1 for Channel 1 and PID Set 6 for Channel 2 are used in the Static Set Point mode.
Autotuning ProcedureAutotuning cannot be initiated while a profile is running. It can only be initiate

d 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. A message 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.
To Clear an Alarm or ErrorIn 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 . . A pop-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.
?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.
Auto-tune PIDIn 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. 3.4 ■ Operations
Edit PIDEdit 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
Integral (Reset): Define the integral time in minutes p

er 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.
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 SetsEnvironmental 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.
Manual Tuning Procedure1. 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
Multiple Tuning Procedure1. 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.

CascadeCascade 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 Autotuning Procedure1. 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.
Cascade Setup Procedure1. 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, an

πAndy, 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.?
