Chapter 1: Overview

The Watlow Series SD family of PID, microprocessor-based temperature controllers is available in 1/32, 1/16, 1/8 and 1/4 DIN panel mount sizes.* The product family includes a static set point PID control version, a PID profiling (ramp and soak) version and an FM approved limit version. All models have a single, universal input that accepts various thermocouples, RTDs (resistive temperature devices) or process inputs. (See the Specifications in the Appendix for further details).

The Series SD PID controllers offer up to two outputs on the 1/32 DIN, and up to three outputs on all others. Outputs can be configured as heat, cool, alarm or off (deactivated). The control outputs can be independently configured for PID or On-Off control. PID settings include proportional band, reset (or integral) and rate (or derivative).

The Series SD PID profiling (ramp and soak) controllers are available as a factory order option for any of the Series SD DIN sizes. The profiling feature allows the user to program up to 4 profiles of 10 steps each. The files can be linked to support a single file of up to 34 unique steps. The Series SD profiling units can also operate as a closed loop static set point controller or manual mode (open loop, percent power) operation capabilities. Outputs can be configured as heat, cool, alarm, event or off (deactivated).

Standard Series SD features include an IP65/NEMA 4X front panel rating; CE compliance, UL, CUL, CSA and NSF agency approvals; dual, four-digit displays in red or green**; autotuning for heat and cool outputs; ramp to set point, to gradually warm up your thermal system; and automatic/manual capability with bumpless transfer. A low-voltage model is also available.

Advanced features include Modbus, EIA-485 serial communications to interface with PC software applications; INFOSENSE™ technology that provides low-cost, high-accuracy thermal sensing; and infrared remote communication for easy-to-use controller setup and monitoring.***

Other operator-friendly features include LED indicators to aid in monitoring and setting up the controller, as well as a calibration offset at the front panel. The Watlow Series SD family automatically stores all information in non-volatile memory and provides an additional back-up for user-selected settings.

For more information on these and all other product features, refer to the Features chapter and the Appendix.

* Also available in an FM-approved limit version.

** The 1/32 DIN controller comes only with a red

How to use the Series SD controller

Before you use your Series SD controller, it must be

installed and configured correctly. The setup steps you

need to perform will depend on how you will use it.

If you purchased the controller to design into your products:

You will need to do the first three steps and maybe some of the fourth step. Some wiring, such as the final wiring of a communications connection or an alarm output for signaling an external device, might be left to the end user. In highly specialized applications with little variation in operation and heat load, the OEM might configure almost all the parameters.

If you purchased the controller to design and install into new equipment for your own use or to retrofit into existing equipment:

You will need to complete all four steps.

If you purchased the controller installed in equipment designed around it:

You will probably only need to do the fourth step. In some instances, you may need to wire it for serial communications and/or an alarm output. Some serial communications parameters on the Setup Page may need to be changed.

Step 1: Mount and install the controller.

The Series SD controller is designed to be panel mounted in a standard DIN opening. The Series SD is available in 1/32 DIN, 1/16 DIN, 1/8 DIN-horizontal, 1/8 DIN-vertical and 1/4 DIN sizes. Cut the correct size hole into the panel and mount the controller, using its mounting brackets. See the Install and Wire chapter for details on installation and mounting.

If you retrofit the Series SD controller into an existing application, you may need to modify an existing opening, either by cutting it larger for a larger controller or using a Watlow adapter plate to adapt it to a smaller controller.

Step 2: Wire the controller.

The controller will need to have its power, input and output wiring installed. The wiring depends on the specific model number of the Series SD controller. The dimension illustrations in the Install and Wire chapter show the location of the model number on each DIN size. Use the model number to determine which wiring diagrams to follow for your controller. See the Install and Wire chapter for wiring details.

Step 3: Configure the Setup Page.

Setup Page parameters tell the controller what input and output devices are wired to the controller and how the controller should function. Without the proper Setup Page settings, the controller will not operate or could operate erratically. Since these settings require detailed knowledge on the wiring and operation of the equipment, the OEM or the designer normally programs these parameters. Some settings, such as the baud rate or controller address, are Setup Page parameters, but would probably be set by the end user.

These settings should be recorded for future reference. The settings can also be stored using the [Usr;S] parameter, on the Factory Page. For saving and restoring parameters, see the Features chapter. For details on configuring the Setup Page, see the Setup Page chapter.

Step 4: Configure the Operations Page.

The Operations Page contains the parameters that the equipment operator may need to set or change from time to time. This includes calibration offset, autotune, PID parameters and alarm set points. In some cases the OEM manufacturer may set most of these parameters because the equipment operates with little variation. In equipment where demands could vary significantly, the OEM may leave parameter adjustments to the end user.

The Operations Page on the Series SD controller is customizable so that only the parameters that the operator may need to use will appear in the display. Settings that won’t need to be adjusted can be hidden from the operator, using the Programming Page. For more details on the Programming Page, see the Features chapter. For details on configuring parameters in the Operations Page, see the Operations Parameters Tables. Once you have verified the controller is operating properly, be sure to document all of your parameter settings. Each

parameter table has a settings column for you to write in your values.

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

2. Check that the rubber gasket lies in its slot at the back of the bezel. Insert

the controller into the panel cutout.

3. While pressing the bezel firmly against the panel, slide the mounting

bracket over the back of the controller.

4. If the installation does not require an IP65/NEMA 4X seal, slide the brack-

et up to the back of the panel enough to eliminate the spacing between the gasket and the panel.

For an IP65/NEMA 4X seal, use your thumb to lock the tabs into place

while pressing the controller from side to side. Don’t be afraid to apply enough pressure to properly install the controller. If you can move the controller back and forth in the cutout, you do not have a proper seal. The tabs on each side of the bracket have teeth that latch into the ridges.

Each tooth is staggered at a different depth (from the front) so only one of

the tabs on each side is ever locked into the ridges at any time. Either the two middle tabs or the two tabs diagonal from each other will be engaged.

5. If the matching tabs are not engaged, you do not have an IP65/NEMA 4X

seal. The space between the bezel and panel must be 0 to 0.48 mm (0 to

0.019 in) maximum.

Tools required:

Putty knife or equivalent

Wiring the Series SD

Warning: Use National Electric (NEC) or other country-specific standard wiring and safety practices when wiring and connecting this controller to a power source and to electrical sensors or peripheral devices. Failure to do so may result in damage to equipment and property, and/or injury or loss of life.

Note: To prevent ground loops, isolation needs to be maintained from input to output when using switched DC or analog process outputs.

Isolation Blocks

There are no electrical connections between these blocks.

Sensor Input Switched DC Outputs Analog Process Outputs

Relay outputs (mechanical and solid-state) provide isolation through their relay contacts. Each relay output is isolated from the blocks above and is isolated from other relay outputs.

The model number for each output option appears with its wiring diagram. Check the label on the controller and compare your model number to those shown here and to the model number breakdown in the Appendix of this manual.

The connectors on the back of the Series SD are different for different model numbers. Where two different combinations of connectors may appear, we show both in the diagrams.

All outputs, including normally open and normally closed contacts, are referenced to a de-energized state (the controller has power removed).

All wiring and fusing must conform to the National Electric Code and to any locally applicable codes as well.

Selecting an EIA/TIA-232 to EIA/TIA-485 Converter

When choosing an EIA/TIA 232 to 485 converter, look for one with the following features:

Two-wire capability

TD (A)

GND

TD (B)

GND

EIA/TIA-485 can be implemented as a two-wire

system or a four-wire system. Most Watlow control-

485SD9TB

lers, including the Series SD, use two-wire communications when working with EIA/TIA-485. The

Watlow p/n 0830-0473-0001

converter selected must have a two-wire mode. Some converters can only be used in a four-wire mode.

Automatic Send Data control

In a two-wire system, both the transmitted signals

and the received signals travel over the same pair of wires, so the converter must have a method of changing from the transmit mode to the receive mode. Some converters require the toggling of a

Figure 18a — B&B Converters Isolated Converter - 4850I9TB Non-Isolated Converter - 485SD9TB B&B Electronics Manufacturing Company, (815) 433-5100, http://www.bb-elec.cm/

6 ft. comms cable Watlow p/n 0830-0473-0003

control line (usually the RTS line) to perform this transition, while others use an automatic timing circuit. The toggling method is dependent on the PC software to toggle the control line and the PC’s operating system to make that transition happen in a timely manner. Because of these dependencies, the best choice for a converter is one with automatic control.

Isolation

Converters are available with or without input-to-

output isolation. An isolated converter is not a requirement when used with the Series SD, but it is recommended to avoid ground loops. Isolation could be a consideration when the Series SD will be used on a network with other devices that may require isolation.

Power Supply

Figure 18b — CMC Non-Isolated Converter - ADA485L CMC Connecticut Micro-Computer, Inc., 1-800-426-2872, http://www.2cmc.com/

Many converters can be powered up either through

the signals of a serial port or through an external power supply. Because some computers, such as laptops, do not always provide enough power to

Ethernet Gateway

The EM00-GATE-0000 is a bridge that allows

up to 32 Watlow controllers to be directly connected to an Ethernet network.

The gateway provides a bridge for Modbus

messages between the Ethernet bus and EIA485 or EIA-232 links. The Gateway supports full product configuration monitoring and configuration of runtime parameters via MODBUS TCP over TCP/IP using a software package such as Watlow’s WATVIEW™.

The Series SD can be configured using WAT-

VIEW with or without the EM Gateway.

For more information, go to www.watlow.com

and search on EM Gateway.

Note: The 32 controller maximum is a functional limitation of the Ethernet Gateway.

Running a Profile

To run a profile:

1. You must start from the Home Page. Press the

Infinity Key ˆ to exit a menu and return to the Home Page. Press the Infinity Key ˆ from the Home Page to enter the Pre-Run menu. The profile light will begin flashing. The lower display will indicate [File] and upper display will indicate the file number.

2. Use the Up ¿ or Down ¯ key to select the de-

sired file number to run. Press the Advance Key ‰. The lower display will indicate [Step] and the upper display will indicate the step number.

3. Use the Up ¿ or Down ¯ key to select the de-

sired step number to start the profile on. Press the Infinity Key ˆ to begin the profile. The profile light will go full on.

Profile Errors

If the lower display alternates between a set point and file.step, there is an error in the step. For example, if the display flashes Step 1, and the profile will not run until the problem has been corrected. Check the program step for accuracy.

[~~1;1]

, there is a problem with File1,

To resume a profile on hold:

1. You must start from the Home Page. Press the

Infinity Key ˆ to exit a menu and return to the Home Page. Press the Infinity Key ˆ to enter the Pre-Run menu. [SELC] will appear in the lower display.

2. Use the Up ¿ or Down ¯ key to select [resU]

in the upper display. The profile will continue starting with the step it was running when it was placed on hold.

Editing a Profile on Hold

The profile can be edited* while in the hold mode. If you edit a step that has not yet been executed, the controller will execute that step using the new settings once the profile is resumed. When editing a step that is already in progress, the controller will adjust the current step utilizing the changed settings once the profile is resumed. The step will run as if it was the beginning of the step, including the jump count for a jump step. For example, if you are 3 minutes into a 20 minute step and you change the time, the step starts over at the beginning of the step when the profile is resumed. The new settings will be retained and used in future runs of that profile.

Holding and Resuming a Profile

If for some reason you need to pause a profile that is running, the profile can be put into a hold mode. While the profile is on hold, you may have full access* to the Setup, Operation and Programming menus to make any required changes. The profile can continue from where it left off using the resume function.

To hold or stop a running profile:

1. You must start from the Home Page. Press the

Infinity Key ˆ to exit a menu and return to the Home Page. Press the Infinity Key ˆ to enter the Pre-Run menu.The profile light will begin flashing. [SELC] will appear in the lower display.

2. Use the Up ¿ or Down ¯ key to select [hold]

in the upper display to maintain the present set point and pause the profile. The profile will now be on hold until either [ResU] or [~Off] is selected from the Pre-Run menu. Selecting [~Off] in the upper display will stop the profile and move the set point to [~Off].

Note: A Pre-Run check verifies that all profile steps are valid before allowing a profile to be started or resumed. A flashing File/Step number in the lower display indicates invalid information in a profile step. See Troubleshooting section.

* The Lockout parameter in the Setup Page determines your level of access to the other pages and menus, including the PreRun and Run menus.

Step Types

Set Point Step

The set point step is used to establish a controller setting within a profile. Set points can be established instantaneously or over some period of time. Establishing a set point over time is also referred to as ramping. The Series SD allows for two methods of expressing a set point ramp, time-based or rate-based. Use the Profile Type

[Ptyp]

ramp type.

When expressed as time target set point and the amount of time desired to increment the current set point towards the target set point. Setting a time of 0 hours, 0 minutes, and 0 seconds causes the set point to be established instantaneously.

When expressed as rate target set point and the rate in degrees per minute to increment the current set point towards the target set point. Setting a ramp rate of 0 degrees per minute causes the set point to be established instantaneously. In either time or rate based programming, it is only a manipulation (increment or decrement) of the controller’s setting, not the actual process value. To limit set point movement or timing based on the actual process value, use the Guaranteed Soak function and/or the Wait-for Process function of a Soak step.

parameter on the Setup Page to select the

[~~ti]

[rate]

, the user enters the

Watlow Series SD • 52 • Chapter 10 Profiling

Soak Step

A Soak step maintains the set point from the previous step for the time in hours, minutes and seconds entered into the step. It is not necessary to enter a set point for this step, only the time duration, the event output states and the Wait-for Process function. The Wait-for function can be enabled or disabled from the Wait-for Process Enable

[WF;P]

for each individual Soak step. The Wait-for Process function causes the controller to pause the timer until the process value passes through the Wait-for Process value

[WPr]

. Once the Wait-for Process value is satisfied, the Wait-for function is not active until the step runs again.

Note: If you have Guaranteed Soak Deviation enabled, the Waitfor Process function is satisfied once the process enters the Guaranteed Soak Deviation window.

* The Lockout parameter in the Setup Page determines your level of access to the other pages and menus, including the PreRun and Run menus.

Jump-loop Step

A profile can jump forward or backwards from any step, except Step 1 of any file. You cannot jump-loop to the step that you are on.

Jump-loop example: Step 1 Step 2 Step 3 Step 4 Step 5

Step 6 In this example the program will execute steps 2 through

4 a total of 2 times. This includes the initial pass and the pass associated with the Jump Count of 1. Following the second pass, the End step (Step 6) will be executed and the program will end. The Jump Count can be any number from 0 to 255. If you enter 0, this will be an infinite loop and never progresses to Step 6. When Jump File is not set to the current program file, the profile may jump to any step of any programmed files.

End Step

The End step ends the profile and selects the status of the control set point and event outputs when a profile finishes. When Hold

[hoLd]

is selected, the control set point and event outputs maintain the same state they were in before the End step was executed. When selected as Off

[~Off]

, the control set point will be set to off (control outputs off) and any event outputs will be set to the off state.

Event Outputs

The flexibility of the Series SD allows configuration of any available output as an event output. An event output is simply an output that can be turned on or off through a profile step, or manually from the front panel if a profile is not running. The event may turn any number of peripheral devices on or off to assist you in controlling your process or system. For instance, an environmental chamber might need to energize a fan to circulate air at a given time in your profile for one or more steps. The chamber might need to turn lights on or off, lock out the humidification system or activate a video recorder. Each output can be configured as an event output on the Setup Page. Once configured, the option to set an event output’s state appears while programming the steps in a profile. The state can be selected as on or off for each set point step and soak step in the profile.

Guaranteed Soak

The Guaranteed Soak Deviation feature insures that the actual temperature tracks a programmed profile within a window around set point. See figure below. If the deviation value from set point is exceeded, the timer function pauses, and the lower display alternately flashes between

Link File Step

Set Point

The Link File step enables you to link any step other than the first step of a profile to the first step of another profile. Linking profiles allows for a simple method to effectively extend the number of steps available in a profile. All four profiles of the Series SD can be linked together to effectively give you a profile with 40 steps.

Guaranteed Soak Deviation Window around Set Point

However, each link step consumes one of the available profile steps and Step 10 of each profile is an End step. If you link File 1 to File 2, File 2 to File 3 and File 3 to File 4, only 34 steps would be available to perform the actual

Example profile

Gwen, of Smith Manufacturing needs to perform a burn-in test of their product in an environmental chamber. The test should take the product through the following sequence:

1. Heat from room temperature to a temperature of 150°F over a 1-hour period.

2. Hold the temperature at 150°F for 2 hours.

3. Cool the temperature to 32°F as quickly as possible.

4. Once the temperature reaches 32°F, hold that temperature for 2 hours.

5. Stop controlling the temperature and allow it to return to room temperature naturally.

Use the master step chart to map out the profile.

Operations Page

Watlow’s patented user-defined menu system improves operational efficiency. The user-defined Operations Page provides you with a shortcut to monitor or change the parameter values that you use most often. You can go directly to the Operations Page from the Home Page by pressing the Advance Key ‰.

You can create your own Operations Page with as many as 20 (23 on profiling version) of the active parameters from the list in the Keys and Displays chapter. When a parameter normally located in the Setup Page is placed in the Operations Page, it is accessible through both. If you change a parameter in the Operations Page, it is automatically changed in its original page. If you change a parameter in its original page it is automatically changed in the Operations Page.

The default parameters will automatically appear in the Operations Page.

To change the list of parameters in the Operations Page, hold down the Infinity Key ˆ, then press the Advance Key ‰, and hold both down for about six seconds. This will take you to the Programming Page.

Note: On profiling version, keys must be pressed exactly at the same time to enter the Programming Page.

Press the Advance Key ‰ once to go to the first selection in the page. The parameter choices will appear in the top display and the selection number will appear in the bottom display. Use the Up ¿ or the Down ¯ key to

Tuning the PID Parameters

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 Autotune Set Point four times to complete the autotuning process. Once complete, the controller controls at the normal set point, using the new parameters.

3. When the system stabilizes, watch the process value. 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.

4. When the process has stabilized, watch the percent power, [Po;ht] or [Po;Cl]. It should be stable ±2%. At this point, the process temperature should also be stable, but it will have stabilized before reaching set point. The difference between set point and actual can be eliminated with reset.

5. Start with a reset* value of 0.01 (99.99)** and allow 10 minutes for the process temperature to get to set point. If it has not, double (halve) ** the setting and wait another 10 minutes. Continue doubling (halving) ** every 10 minutes until the process value equals the set point. If the process becomes unstable, the reset* value is too large (small) **. Decrease (increase) ** the reset value until the process stabilizes.

6. Increase Rate* to 0.10 minute. Then increase the set point by 11° to 17°C. Monitor the system’s approach to the set point. If the process value overshoots the set point, increase 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 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.

Manual Tuning

In some applications, the autotune process may not come up with PID parameters that provide the process characteristics you desire. If the autotune does not provide satisfactory results, you will have to perform a manual tune on the process:

1. Apply power to the Series SD and establish a set

point typically used in your process. If the controller includes the TRU-TUNE+™ option (SD_E-_ _ _ _ - _ _ _ _), set TRU-TUNE+™ Enable to [`~no].

2. Go to the Operations Page, and establish values

for the PID parameters: Proportional Band = 5; Reset* = 0.00; Rate* = 0.00. Autotune should be set to off.

*Note: With the [Unit] parameter set at [``SI] (Setup Page) Integral will appear in place of Reset and Derivative will appear in place of Rate.

**Note: Integral is the reciprocal of reset. For Integral instead of reset, use the values in parentheses.

For additional information about autotune and PID

control, see related features in this chapter.

TRU-TUNE+™ Adaptive Control

If your Series SD controller was ordered with the TRU-TUNE+™ option (SD_E - _ _ _ _ - _ _ _ _) the TRUTUNE+™ feature can be enabled or disabled in the Setup Page. The TRU-TUNE+™ feature is enabled as the default condition. If TRU-TUNE+™ is disabled, the controller will control using fixed PID settings (non adaptive).

The TRU-TUNE+™ adaptive algorithm will optimize the Series SD controller’s PID values to improve the controller’s ability to control difficult-to-control or dynamic processes. TRU-TUNE+™ monitors the process variable and adjusts the control parameters automatically to keep your process at set point during set point and load changes. When the controller is in the adaptive control mode, it determines the appropriate output signal and, over time, adjusts the control parameters to optimize responsiveness and stability. The TRU-TUNE+™ feature does not function for on-off control.

Watlow Series SD • 63 • Chapter 12 Features

Autotune Enable

rameter appears in the Operations Page.

The autotune feature can be enabled if TRU-

TUNE+™ is enabled or disabled.

Autotuning with TRU-TUNE+™ adaptive control is a process by which the Series SD controller calculates the PID settings for optimum control. Both heating and cooling PID parameter settings are determined. The autotune feature can also be enabled if TRU-TUNE+™ has been disabled. The autotune generated PID settings are used until the autotune feature is rerun or the PID variable values are manually adjusted by the user or if TRUTUNE+™ is enabled.

The preferred and quickest method for tuning the Series SD controller when TRU-TUNE+™ is enabled is to use the autotune feature to establish initial control settings and continue with the adaptive mode to fine tune the settings. Enabling the autotune function from the Operations Page starts this two-step tuning function. First the autotune determines initial, rough settings for the PID parameters. Second the loop automatically switches to the adaptive mode, which fine tunes the PID parameters. This function can be used for heat-only, heatand-cool, and cool-only PID control systems.

Once the process value has been at set point for a suitable period of time (about 30 minutes for a fast process to roughly 2 hours for a slower process) and if no further tuning of the PID parameters is desired or needed, TRU-TUNE+™ can then be disabled. However, only operating the controller in the adaptive mode allows it to automatically adjust to load changes and compensate for differing control characteristics at various set points for processes that are not entirely linear.

Once the PID parameters have been set by the TRUTUNE+™ adaptive algorithm, the process, if shut down for any reason, can be restarted in the adaptive control mode.

Autotune Aggressiveness appears in the Setup Page. This parameter is used by the autotune feature to determine how aggressively power is applied to the controllers output to enable the process value to reach the set point.

High Scale and Low Scale

When an analog input is selected as process voltage or process current input, you must choose the value of voltage or current to be the low and high ends. For example, when using a 4 to 20 mA input, the scale low value would be 4.00 mA and the scale high value would be 20.00 mA. Commonly used scale ranges are: 0 to 20 mA, 4 to 20 mA, 0 to 5V, 1 to 5V and 0 to 10V.

The Series SD allows you to create a scale range for special applications other than the standard ones listed above. Reversing of the scales from high values to low values is permitted for analog input signals that have a reversed action. For example, 50 psi = 4 mA and 10 psi = 20 mA.

High Range and Low Range

With a process input, you must choose a value to represent the low and high ends of the current or voltage range. Choosing these values allows the controller’s display to be scaled into the actual working units of measurement. For example, the analog input from a humidity transmitter could represent 0 to 100 percent relative humidity as a process signal of 4 to 20 mA. Low scale would be set to 0 to represent 4 mA and high scale set to 100 to represent 20 mA. The indication on the display would then represent percent humidity and range from 0 to 100 percent with an input of 4 to 20 mA.

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

The controller has two basic modes of operation, auto mode and manual mode. Auto mode allows the controller to decide whether to perform closed loop control or to follow the settings of the Input Error Failure Mode parameter (Setup Page). The manual mode only allows open loop control. The Series SD controller is normally used in the auto mode. The manual mode is usually only used for specialty applications or for troubleshooting.

Manual mode is open loop control that allows the user to directly set the power level to the controller’s output load. No adjustments of the output power level occur based on temperature or set point in this mode.

In auto mode, the controller monitors the input to determine if closed loop control is possible. The controller checks to make certain a functioning sensor is providing a valid input signal. If a valid input signal is present, the controller will perform closed loop control. 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 to reduce that difference.

If a valid input signal is not present, the controller will indicate an input error message use the Input Error Failure Mode termine operation. You can choose to have the controller perform a “bumpless” transfer, switch power to output a preset manual level, or turn the output power off.

Bumpless transfer will allow the controller to transfer to the manual mode using the last power value calculated in the auto mode if the process had stabilized at a ±5 percent output power level for two minutes prior to sensor failure, and that power level is less than 75 percent.

Control Methods

Output Configuration

Each controller output can be configured as a heat output, a cool output, an alarm output or deactivated. No dependency limitations have been placed on the available combinations. The outputs can be configured in any combination. For instance, all three could be set to cool.

Analog outputs can be scaled for any desired current range between 0 and 20 mA or voltage range between 0 to 10V. The ranges can be reversed to high-to-low for reverse acting devices.

Heat and cool outputs use the set point and Operations parameters to determine the output value. All heat and cool outputs use the same set point value. Heat and cool each have their own set of control parameters. All heat outputs use the same set of heat control parameters and all cool outputs use the same set of cool output parameters.

Each alarm output has its own set of configuration parameters and set points, allowing independent operation.

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, and may result in the output “chattering.” On-off control can be selected with Heat Control Method Method

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 the process value is to the set point, the lower the output power. 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 the 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 the proportional band value.

Proportional plus Integral (PI) Control

The droop caused by proportional control can be corrected by adding integral (reset) 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 is in effect if PID Units are set to SI, and is measured in minutes per repeat. A low integral value causes a fast integrating action.

Reset is in effect if PID Units are set to US, and is measured in repeats per minute. A high reset value causes a fast integrating action.

50% would result in an actual output power level of 50%. But if the PID calculated power output is 100%, then the power level will be 70%.

Power scaling establishes the maximum power output and the minimum power output. The output power is then linearly scaled within that range. The default values of Output Power Scale Low of 0% and Output Power Scale High of 100% in effect disable power scaling.

Linear scaling allows the controller to do calculations over the full range of power (0 to 100%) and adjust that calculation within the actual output span. For instance, if scale low is set to 15% and scale high is set to 80%, the output power will always be between 15 and 80%. If the PID calculation is 100%, the output power will be 80%, which is the same result you would get from a power limit of 80%. However, if the PID calculation for heat is 50%, the output will be 50% of the allowable range, which scales to an actual output of 47.5%.

Power limiting and power scaling affect the specified output at all times, including in on-off control, manual mode and autotuning.

Variable Time Base

Variable time base is the preferred method for controlling a resistive load, providing a very short time base for longer heater life. Unlike phase-angle firing, variabletime-base switching does not limit the current and voltage applied to the heater.

With variable time base outputs, the PID algorithm calculates an output between 0 and 100%, but the output is distributed in groupings of three ac line cycles. For each group of three ac line cycles, the controller decides whether the power should be on or off. There is no fixed cycle time since the decision is made for each group of cycles. When used in conjunction with a zero cross (burst fire) device, such as a solid-state power controller, switch-

Watlow Series SD • 69 • Chapter 12 Features

ing is done only at the zero cross of the ac line, which helps reduce electrical noise (RFI).

Variable time base should be used with solid-state power controllers, such as a solid-state relay (SSR) or silicon controlled rectifier (SCR) power controller. Do not use a variable time base output for controlling electromechanical relays, mercury displacement relays, inductive loads or heaters with unusual resistance characteristics.

The combination of variable time base output and a solid-state relay can inexpensively approach the effect of analog, phase-angle fired control.

You must select the AC Line Frequency, 50 or 60 Hz.

Alarms

Alarms are activated when the process value or temperature leaves a defined range. A user 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.

Process or Deviation Alarms

A process alarm uses one or two absolute set points to define an alarm condition.

A deviation 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.

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.

Any process output can be configured as a retransmit output.

Communications

Overview

A Series SD controller can also be programmed and monitored by connecting it with a personal computer or programmable logic controller (PLC) via serial communications. To do this it must be equipped with an EIA/TIA485 (SD_ _ - _ _ U_ - _ _ _ _) communications option for Output 2. Your PC or PLC must have available an EIA/ TIA-485 interface or use an EIA/TIA-232 to EIA/TIA-485 converter. See “Selecting an EIA/TIA-232 to EIA/TIA-485 converter” in the Install and Wire chapter. The EIA/TIA485 option directly supports communication with up to 32 devices on a network or up to 247 devices using a 485 repeater.

Basic communications settings must first be configured on the controller in the Setup Page. Match the Baud Rate

[bAud]

Address

RTU protocol to read or write to registers in the controller. See the parameter tables for information about the Modbus registers. These registers contain the parameter values that determine how the controller will function and current input and output values of the system. The address in the tables have been offset by subtracting 40,001 from each one.

Two consecutive registers are addressed for 32-bit data types. The first word, or lower register number, contains the two higher bytes. The second word, or higher register number, contains the two lower bytes of the four byte integer value.

Note: All temperature related values accessed via Modbus are in degrees F.

Setting Up a Modbus Network

1. Wire the controllers.

The Series SD uses an EIA/TIA-485 serial port, which is not typically found in a PC, but can be found on many PLC’s. The type of port found in a typical PC is an EIA232 port. Internal EIA/TIA-485 PC ports are available, but the most common way for a PC to communicate using a EIA-485 port is with an EIA/TIA-232 to EIA/TIA-485 converter. See “Selecting an EIA/TIA-232 to EIA/TIA-485 converter” in the Install and Wire chapter.

The advantages of EIA/TIA-485 are that it is less susceptible to noise and it allows a PC or PLC to communicate with multiple controllers on the same port to form a network. It is important when using EIA/TIA-485, to install the termination resistors along with pull-up and pull-down resistors to ensure reliable communications.

Some newer PCs may only have a USB port. USB-toserial adapters (usually EIA/TIA 232) are available from a variety of different PC vendors. Some companies offer adapters to convert from USB to EIA/TIA-485 directly.

2. Configure each controller’s communications parameters in the Setup Menu using the front panel.

Only a couple of communications parameters need to be configured on the controller, Baud Rate and Modbus Device Address. The choices for Baud Rate are 9600 bps, 19200 bps or 38400 bps. 38400 baud allows for the fastest communication. For compatibility with other devices, reducing noise susceptibility, or increasing communications distance, 9600 bps could be chosen. When using EIA/TIA485, all devices connected to that port must use the same Baud Rate. The Modbus address is used to identify each controller on the network. With EIA/TIA-485, every controller on the network must have a unique address.

3. Choose a device to communicate with the controller.

The controller can communicate with devices, such as a computer running a software program, a PLC (Programmable Logic Controller) or an OIT (Operator Interface Terminal). Whichever device is chosen, it needs to be able to communicate using the Modbus RTU Protocol. OITs would need to be ordered with Modbus RTU support. PLCs would either have Modbus RTU as a standard feature or it can be made available with an I/O module.

On a computer, the software package to be used would need to have the Modbus RTU capability.

4. Select a software package for the computer.

Select the software package based on what is required from the application. For basic communications (such as reading the process value or setting the set point), Watlow has the Comm7 software package. This is mainly used for diagnostics and basic communications.

The WATVIEW™ software package offers more advanced features. WATVIEW™ is available in three editions, each offering increasing levels of functionality. If you need functionality beyond WATVIEW™ or need to interface with an existing software package, many other third party software packages can interface with the Series SD.

When purchasing a third-party software package, be sure to look for a package that is Modbus RTU compatible or has Modbus RTU drivers. Most third-party packages require you to specify the Modbus registers of the controller to setup the package.

Another option is to custom-create a software package. Using the Modbus register and data information in this user’s manual, a software package can be created and tailored to the desired application. To assist in application development, Watlow offers WATCONNECT™, which is a Windows-based software library for Modbus RTU communications. For further information on WATVIEW™ software packages, the WATCONNECT™ software library, or to download the Comm7 software, go to the Watlow web site at http://www.watlow.com.

5. Configure the software’s communications parameters.

A software package, (be it software for a Computer, a PLC or an OIT) will need to be configured just as the controller was configured, setting the Baud Rate and Address to match. The software package may have additional parameters to set, such as number of data bits, parity and stop bits. For Watlow controllers using modbus, these should always be set at 8 data bits, no parity, and 1 stop bit. This is often written as “8N1”. Some software packages may give the option to control the activity of the RTS, CTS and DTR lines, which are sometimes used by EIA-232 to EIA-485 converters. On packages where the Modbus registers for the controller need to be defined, these values can be entered at this time. Be sure to account for offsets.

6. Test the communications.

Once communications is configured, test the link to the controller for verification that everything is wired and configured properly. Check the wiring and configurations if things aren’t working. One misplaced wire or one incorrect setting will keep communications from working. When using an EIA-232 to EIA-485 converter, be sure to follow the configuration instructions provided with the converter, as some may require special jumper/switch settings, external power supply requirements or special signals from the software. Some software packages have built-in routines for testing the communications or use Comm7 to help diagnose problems.

Watlow Series SD • 72 • Chapter 12 Features

7. Start communications with the controller.

With the communications successfully verified, the software is now ready for use with the controller. The above guidelines are the general steps to establishing communications with controllers using Modbus. Some applications may require other steps not mentioned, but would follow the same general process.

8. Programming and configuring the controllers.

When programming and configuring the controllers with a software program, a couple of things must be kept in mind. If the software allows changing Setup parameters such as Input Type, other parameter values that are dependent on that setting may be automatically changed. Some software packages may warn you of this possibility and others may not.

Also, some controllers require that any changes made by the software program to controller parameters that need to be retained in the controller memory must be saved in the non-volatile memory writes register. Any settings not saved to controller memory will be lost when the controller’s power is turned off.

Writing to Non-Volatile Memory

The Series SD stores parameter values in non-volatile EEPROM memory. This type of memory has a finite life of approximately 100,000 write cycles. In some applications, you might need to constantly write new values to a particular register. Examples might be the writing of ramping set points or repetitive loops through serial communications. Continuous writes may result in premature controller failure and system downtime.

To prevent premature failure of the EEPROM when frequently writing register values, write a 0 to register

17. Any values written after that, will not be stored to EEPROM. However, this data is lost when power is removed. Register 17 defaults to a value of 1 after each power cycle, writing values to EEPROM again. You must write a 0 to register 17 upon power up to prevent data from being written to EEPROM.

Advantages of this feature include automated logging of key process variables, increased accuracy and ease of use for recipe or configuration setups, and easier controller data exchange in physically restricting environments, such as semiconductor clean rooms. This feature reduces the use of paper to record instrument information as well as human transposition errors.

Infrared Data Communications (IDC)

Infrared Data Communications is an option available on the 1/16th, 1/8th and 1/4 Din Series SD products. This option supports wireless communications with PDAs (personal digital assistants) or other devices equipped with infrared communications that support the IrDA 1.0 Standard. IrDA is an acronym for the Infrared Data Association, www.irda.org. A PDA or other master device communicates with the SD Series using Modbus ASCII via IRCOMM over IrDA. IDC supports wireless communications through transparent material to a distance of no less than one meter between devices at a maximum angle of 15 Degrees.

IDC can support complete Series SD parameter configuration and operation. The actual user interface or configuration is dependent on the master device (PDA) application software. A source for this software is Instant HMI from Software Horizons. For more information, go to
