Chapter 1: Overview

The EZ-ZONE® ST Provides Total Thermal System Control

The EZ-ZONE ST solid-state controller offers complete thermal system control in a single package while reducing system complexity and the cost of control-loop ownership. You can order a PID controller already connected to a high-amperage, solid-state relay capable of zero cross or phase angle firing with the option of adding a properly sized heat sink, an over-under temperature limit, a shut-down power contactor, and digital communications in one package.

It just got a whole lot easier to solve the thermal requirements of your system. Because the EZ-ZONE ST along with the entire family of EZ-ZONE controls are highly scalable where you pay only for what you need. So if you are looking for a PID controller with high amperage outputs, an over-under limit controller or an integrated controller, the EZ-ZONE ST is the answer.

A Conceptual View of the ST

The flexibility of the ST software and hardware allows a large range of configurations. Acquiring a better understanding of the controller's overall functionality and capabilities while at the same time planning out how the controller can be used will deliver maximum effectiveness in your application.

It is useful to think of the controller in terms of functions; there are internal and external functions. An input and an output would be considered external functions where the PID calculation would be an internal function. Information flows from an input function to an internal function to an output function when the controller is properly configured. A single ST control can carry out several functions at the same time. For instance, closed-loop control monitoring for several different alarm situations, while at the same time operating switched devices, such as lights and motors. Each process needs to be thought out carefully and the controller’s various functions set up properly.

Inputs Functions

The inputs provide the information that any given programmed procedure can act upon. In a simple form, this information may come from an operator pushing a button or as part of a more complex procedure it may represent a remote set point being received from another controller.

Each analog input typically uses a thermocouple or RTD to read the temperature of something. It can also read volts, current or resistance, allowing it to use various devices to read humidity, air pressure, operator inputs and others values. The settings in the Analog Input Menu (Setup Page) for each analog input must be configured to match the device connected to that input.

Each digital input reads whether a device is active or inactive. A controller with digital input-output (DIO) hardware includes two sets of terminals each. Each DIO must be configured to function as either an input or output with the Direction parameter in the Digital Input/Output Menu (Setup Page).

The EZ-ZONE Remote User Interface (RUI) has a function, or EZ Key on the front panel, this too can be configured as a digital input by toggling the function assigned to it in the Digital Input Function parameter in the Function Key Menu (Setup Page). If interested in learning more about the RUI and how it is used with the ST retrieve the RUI user manual from the Watlow web site. Point your browser to:

http://www.watlow.com/literature/pti_search.cfm?dltype=5

Once there, type in EZ-ZONE for a keyword at the bottom of the page and then click on the search button to find the user manual.

set a state to true or false, or reading a temperature to set an alarm state to on or off. Or, it could compare the temperature of a process to the set point and calculate the optimal power for a heater.

To set up a function, it’s important to tell it what source, or instance, to use. For example, an alarm may be set to respond to either analog input 1 or 2 (instance 1 or 2, respectively).

Outputs Functions

Outputs can perform various functions or actions in response to information provided by a function, such as operating a heater, driving a compressor, turning a light on or off, unlocking a door, turning on a buzzer etc...

Assign an output to a Function in the Output Menu or DIO Menu. Then select which instance of that function will drive the selected output. For example, you might assign an output to respond to alarm 2 (instance 2).

You can assign more than one output to respond to a single instance of a function. For example, alarm 2 could be used to trigger a light connected to output 1 and a siren connected to digital output 5.

Input Events and Output Events

Input and output events are internal states that are used exclusively by profiles. The source of an event input can come from a real-world digital input or an output from another function. Likewise, event outputs may control a physical output such as an output function block or be used as an input to another function.

Internal Functions

Functions use input signals to calculate a value. A function may be as simple as reading a digital input to

Getting Started Quickly

The ST control has a page and menu structure that is listed below along with a brief description of its purpose.

Setup Page

Push and hold the up and down keys (¿ ¯) for 6 seconds to enter. (See the Setup Page for further information)

Operations Page

Push and hold the up and down keys (¿ ¯) for 3 seconds to enter. (See the Operations

Page for further infor-

mation)

Factory Page

Push and hold the Infinity and the green Advance keys (ˆ ‰) for 6 seconds to enter. (See the Factory Page for further information)

Profile Page

Push and hold the the green Advance key ‰ for 6 seconds to enter. (See the Profile Page for further information)

The default ST loop configuration out of the box is shown below:

• Analog Input functions set to thermocouple, type J

• Heat algorithm set for PID, Cool set to off

• Output 1 set to Heat

• Control mode set to Auto

• Set point set to 75 °F

If you are using the input type shown above, simply connect your input and output devices to the control. Power up the control and push the up arrow ¿ on the face of the control to change the set point from the default value of 75 °F to the desired value. As the Set Point increases above the Process Value, output 1 will come on and it will now begin driving your output device.

Once received, a user would want to setup their control prior to operation. As an example, define the input type and set the output cycle time.

After setting up the control to reflect your equipment, the Operations Page would be used to monitor or change runtime settings. As an example, the user may want to see how much time is left in a profile step or perhaps change the autotune set point.

For the most part the Factory Page has no bearing on the control when running. Here, a user may want to enable password protection, view the control part number or perhaps create a custom Home Page.

If equipped with this feature, a user would want to go here to configure a profile.

Note:

The output cycle time will have a bearing on the life of mechanical relay outputs and can be different based on the type of output ordered. The output cycle time can be changed in the Setup Page under the Output Menu.

Installation

Mounting and Dismounting the Controller from a DIN Rail

To mount the controller on a DIN rail, first hook the top flange on the back of the heat sink on to the top of the DIN rail. Then rotate the controller to an upright position until the lower flange snaps into place.

Note: Typically, the DIN rail is mounted before com-

ponents are mounted on it.

To dismount the controller, first use a screwdriver to pull down the small lever on the bottom of the heat sink and rotate the bottom of the controller forward. Then lift the the controller off of the rail.

Replacing the Solid-State Relay on a Controller without a Contactor (ST _ _-A _ _ _-_ _ _ _)

1. Pinch the release levers on the top and bottom of the control module and lift the bottom edge forward to detach the unit.

4. Using a Phillips screwdriver, remove the two screws connecting the solid-state relay to the heat sink.

2. With a Phillips screwdriver, remove the four nearest screws that were under the module.

Note: For controller models without a contactor (ST _ _-A _ _ _-_ _ __),

the solid-state relay must be mounted with the larger power terminals on the top and the smaller control terminals on the bot tom.

3. Lift the controller body, exposing the solid-state relay.

Replacing the Solid-State Relay

1. Using a Phillips screwdriver, replace the two screws connecting the solidstate relay to the heat sink.

2. Place the controller body over the solid-state relay and, using a Phillips screwdriver, replace the four screws securing it.

3. Snap the control module in place, bottom edge first.

Note: Factory calibration is done using control and base modules as

matched pairs. Due to this fact, current detection (if turned on) may not read accurately if a control module is placed into another base module.

Quencharc Wiring Example

In this example the Quencharc circuit (Watlow part# 0804-0147-

0000) is used to protect ST internal circuitry from the counter electromagnetic force from the inductive user load when de-engergized. It is recommended that this or an equivalent Quencharc be used when connecting inductive loads to ST outputs.

• Internal supply provides a constant power output of 750mW

• Maximum output sink current per output is

1.5A (external class 2 or SELV supply required)

• Total sink current for all outputs not to exceed 8A

• Do not connect outputs in parallel

Setting the Address

Modbus Controller Address

The address of an EZ-ZONE® ST controller with the Modbus option (ST _ _-_ _ M _-_ _ _ _) can be set to ranges from 1 to 8 using the DIP switch and ranges 1 to 247 using software.

Set switch 4 to on to use Modbus communications. Modbus™ RTU addresses from 1 to 247 can be programmed into the controller using Standard bus communications. Only one controller can be connected to the network while changing the address using communications. After the Modbus address is changed, all four DIP switches must be turned on (set to 8) and the controller restarted for the new address be become available on the Modbus network. The Modbus addresses set by software will override only address 8, but lower addresses set on the DIP switch will override the software-assigned addresses.

As many as 247 controllers can be connected to a network.

The Standard bus address of an EZ-ZONE ST controller with the Modbus™ RTU option (ST _ _-_ _ M _-_ _ _ _) ranges from 1 to 8, because DIP switch 4 is reserved for switching Modbus on or off.

After the Modbus address is changed, all four DIP switches must be turned on (set to 8) for the new address to become available on the Modbus network.

Note:

Changing the Modbus parameters listed above must be done over Modbus using ST firmware re lease 2.0 and earlier. For firmware release 3.0 and above using either an RUI or EZ-ZONE Configura tor software, navigate to the Setup Page and then to the Com [Com] (RUI representation) menu to change.

CAUTION: Changes set over Modbus are immediate. Users will not be able to communicate with the controller after its address, parity or baud rate has been changed. The master device will need to be re-configured to the new settings.

Saving Settings to Nonvolatile Memory

When controller settings are entered using the optional RUI, changes are always saved to Non-volatile Memory (EEPROM). If the controller loses power or is switched off, its settings will be restored when it starts again.

The EEPROM will wear out after about 1,000,000 writes, which would not be a problem with changes made from the RUI. However, if the controller is receiving changing instructions from a PLC or a computer through a network connection, the EEPROM could, over time, wear out. The Non-volatile Memory Save parameter allows the user to save settings made over the network to either volatile or nonvolatile memory.

By default, settings made through the network are saved to non-volatile memory.

Note:

Changing Non-volatile Memory Save must be done over the network using ST firmware release 2.0 and earlier. For firmware release 3.0 and above us ing either an RUI or EZ-ZONE Configurator soft ware, navigate to the Setup Page and then to the Com [Com] (RUI representation) menu to change.

Range

Within this column notice that on occasion there will be numbers found within parenthesis. This number represents the enumerated value for that particular selection. Range selections can be made simply by writing the enumerated value of choice using any of the available communications protocols. As an example, turn to the Setup Page and look at the Analog Input [`Ai] menu and then the Sensor Type [Sen] prompt (instance 1). To turn the sensor off using Modbus simply write the value of 62 (off) to register 400043 (Map 1) or register 400369 (Map 2) and send

that value to the control.

Communication Protocols

All EZ-ZONE ST controllers come standard with the Standard Bus protocol. As a option it can also be delivered with the Modbus protocol as well. The Standard Bus protocol is used primarily for communications to other EZ-ZONE products to include the RUI and EZ-ZONE Configurator software (free download from Watlow's web site (http://www.watlow.com). Other protocols that can be used to communicate with the ST are available when used in conjunction with the optional Remote User Interface/Gateway (RUIGTW).

- Modbus RTU 232/485

- EtherNet/IP, Modbus TCP

- DeviceNet

- Profibus DP

If interested in learning more about the RUI/GTW download the RUI/Gateway User Manual by pointing your browser to:

Once there move to the bottom of the page and enter EZ-ZONE into the Keyword field and then click the search button.

Modbus RTU & Modbus TCP Protocols

All Modbus registers are 16-bits and as displayed in this manual are relative addresses (actual). Some legacy software packages limit available Modbus registers to 40001 to 49999 (5 digits). Many applications today require access to all available Modbus registers which range from 400001 to 465536 (6 digits). Watlow controls support 6 digit Modbus registers. For parameters listed as float notice that only one (low order) of the two registers is listed, this is true throughout this document. By default the low order word contains the two low bytes of the 32-bit parameter. As an example, look in the Operations Page for the Process Value. Find the column identified in the header as Modbus and notice that it lists register 19 (instance 1, Map 1) and register 360 (instance 1, Map 2). Because this parameter is a float instance 1 Map 1 is actually represented by registers 19 (low order bytes) and 20 (high order bytes), likewise, instance 1 Map 2 is actually represented by registers 360 (low order bytes) and 361 (high order bytes). Because the Modbus specification does not dictate which register should be high or low order Watlow provides the user the ability to swap this order (Setup Page, [Com Menu) from the default low/high [lohi] to high/low [hilo].

Note:

With the release of firmware revision 3.00 and above new capabilities (phase angle control, user programmable memory blocks, etc...) where introduced into this product line. With the introduction of these new capabilities there was a repacking of Modbus registers. Notice in the column identified as Modbus the reference to Map 1 and Map 2 reg-

isters for each of the various parameters. If the new capabilities are to be used, be certain to select Map 2 Modbus registers. If the new functions of this product line are not to be used, Map 1 (legacy ST controls) Modbus registers will be sufficient. The Modbus register mapping [map] can be changed in the Setup Page under the [Com] Menu. This setting will apply across the control.

It should also be noted that some of the cells in the Modbus column as well as the RUI/GTW Modbus column contain wording pertaining to an offset. Several parameters in the control contain more than one instance; such as, profiles (4), alarms (2), analog inputs (2), etc... The Modbus register shown always represents instance one. Take for an example the Step Type [styp] parameter found in the Profile Page. Instance one, Map 1, is shown as address 500 and +20 is identified as the offset to the next instance. If there was a desire to read or write to instance 3 simply add 40 to 500 to find its address. In this case, the instance 3 address for Step Type is 540.

The ST control, when equipped with Modbus has user programmable memory blocks. To learn more about this feature click on the link or turn to the Features section and look for the section entitled "Modbus -

User Programmable Memory Blocks".

Data Types Used with Modbus

unsigned = Unsigned 16 bit integer

signed = Signed 16-bit

float = Float, IEEE 754 32-bit

long = 32 bit unsigned integer

sint = Signed 8 bits , byte

To learn more about the Modbus protocol point your browser to http://www.modbus.org.

Common Industrial Protocol (CIP) DeviceNet & Ethernet/IP

Both DeviceNet and EtherNet/IP use open object based programming tools and use the same addressing scheme. In the following menu pages notice the column header identified as CIP. There you will find the Class, Instance and Attribute in hexadecimal, (decimal in parenthesis) which makes up the addressing for both protocols.

The ST control has a feature that allows for implicit messaging when used in conjunction with an RUI/ GTW equipped with a DeviceNet or EtherNet/IP card.

Chapter 5: Profiling Page

The Profiling Page allows you to enter your ramp and soak profile information.

To go to the Profiling Page from the Home Page, press the Advance Key‰for three seconds, until [ProF] appears in the lower display and the profile number appears in the upper display. Press the Up ¿ or Down ¯ key to change to another profile.

• Press the Advance Key‰to move to the selected profile's first step.

• Press the Up ¿ or Down ¯ keys to move through the steps.

• Press the Advance Key‰to move through the selected step's settings.

• Press the Up ¿ or Down ¯ keys to change the step's settings.

• Press the Infinity Key ˆ at any time to return to the step number prompt.

• Press the Infinity Key ˆ again to return to the profile number prompt.

• From any point press and hold the Infinity Key ˆ for two seconds to return to the Home Page.

Note: Changes made to profile parameters in the Profiling Pages will be

saved and will also have an immediate impact on the running pro file.

Some parameters in the Profile Status Menu can be changed for the currently running profile, but should only be changed by knowledgeable personnel and with caution. Changing parameters via the Profile Status Menu will not change the stored profile but will have an immediate impact on the profile that is running.

How to Start a Profile

After defining the profile follow the steps below to run the profile:

1. From the Home Page push the Advance Key

repeatedly until Profile Start [P;St1] appears in the lower display.

2. Use the Up ¿ or Down ¯ key to choose the file

or step number within a profile where you want the profile to begin running.

3. Press the Advance Key‰. This takes you to Pro-

file Action [P;AC1], where you can select the ap-

propriate action.

• [none] No action

• [ProF] Begin execution from first step of the

specified profile number, whether it exists or not.

• [PAUS] Pause the currently running profile.

• [rESU] Resume running the profile from the

previously paused step.

• [`End] End the profile.

• [StEP] Begin running the profile from the spec-

ified step number.

Note: Avoid continuous writes within loops. Excessive writes to EEPROM

will cause premature EEPROM failure. The EEPROM is rated for 1,000,000 writes. Navigate to Setup Page under the Com menu

and set prompt Non-volatile Save [`nU;S] to No.

Saving and Restoring User Settings

Recording setup and operations parameter settings for future reference is very important. If you unintentionally change these, you will need to program the correct settings back into the controller to return the equipment to operational condition.

After you program the controller and verify proper

operation, use User Save Set [USr;S] (Setup Page, Global Menu) to save the settings into either of two files in a special section of memory. If the settings in the controller are altered and you want to return the controller to the saved values, use User Restore Set [USr;r] (Setup Page, Global Menu) to recall one of the saved settings.

A digital input or the RUI Function Key can also

be configured to restore parameters.

Note:

Only perform the above procedure when you are sure that all the correct settings are programmed into the controller. Saving he set- tings overwrites any previously saved collection of settings. Be sure

to document all the controller settings.

Tuning the PID Parameters

Autotuning

When an autotune is performed on the EZ-ZONE® ST, the set point is used to calculate the tuning set point.

For example, if the active set point is 200° and

Autotune Set Point [A;tSP] (Operations Page, Loop Menu) is set to 90 percent, the autotune function utilizes 180° for tuning. This is also how autotuning works in previous Watlow controllers. In addition, changing the active set point in previous controllers causes the autotune function to restart; where with the EZ-ZONE ST changing the set point after an autotune has been started has no affect.

A new feature in EZ-ZONE ST products will allow set point changes while the control is autotuning, this includes while running a profile or ramping. When the auto tune is initially started it will use the current set point and will disregard all set point changes until the tuning process is complete. Once complete, the controller will then use the new set point.

This is why it is a good idea to enter the active set point before initiating an autotune.

Autotuning calculates the optimum heating and/or cooling PID parameter settings based on the system's response. Autotuning can be enabled whether or not TUNE-TUNE+® is enabled. The PID settings generated by the autotune will be used until the autotune feature is rerun, the PID values are manually adjusted or TRU-TUNE+® is enabled.

To initiate an autotune, set Autotune Request [`AUt] (Operations Page, Loop Menu) to [`YES]. You should not autotune while a profile is running. If the autotune cannot be completed in 60 minutes, the autotune will time-out and the original settings will take effect.

The lower display will flash between [tUnE] and

the set point while the autotuning is underway. The temperature must cross the Autotune Set Point five times to complete the autotuning process. Once complete, the controller controls at the normal set point, using the new parameters.

Select a set point for the tune with Autotune Set Point. The Autotune Set Point is expressed as a percent of the Closed Loop Set Point.

If you need to adjust the tuning procedure's aggressiveness, use Autotune Aggressiveness [T;Agr] (Setup Page, Loop Menu). Select under damped [Un- dr] to bring the process value to the set point quickly. Select over damped [ouer] to bring the process value to the set point with minimal overshoot. Select critical damped [Crit] to balance a rapid response with minimal overshoot.

Manual Tuning

In some applications, the autotune process may not provide PID parameters for the process characteristics you desire. If that is the case, you may want to tune the controller manually.

1. Apply power to the controller and establish a set

point typically used in your process.

2. Go to the Operations Page, Loop Menu, and set

Heat Proportional Band [`h;Pb] and/or Cool Proportional Band [`C;Pb] to 5. Set Time Integral [``ti] to 0. Set Time Derivative [``td] to 0.

3. When the system stabilizes, watch the process

value. If it fluctuates, increase the Heat Proportional Band or Cool Proportional Band value in 3 to 5° increments until it stabilizes, allowing time for the system to settle between adjustments.

4. When the process has stabilized, watch Heat

Power [`h;Pr] or Cool Power [`C;Pr](Operations Page, Monitor Menu). It should be stable ±2%. At this point, the process temperature should also be stable, but it will have stabilized before reaching the set point. The difference between the set point and actual process value can be eliminated with Integral.

5. Start with an Integral value of 6,000 and allow

10 minutes for the process temperature to reach

Watl o w E Z- Z O NE® S T • 6 5 • Cha p ter 7 Fe a tur e s

Page 68

the set point. If it has not, reduce the setting by half and wait another 10 minutes. Continue reducing the setting by half every 10 minutes until the process value equals the set point. If the process becomes unstable, the Integral value is too small. Increase the value until the process stabilizes.

6. Increase Derivative to 0.1. 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 Derivative to 0.2. Increase the set point by 11° to 17°C and watch the approach to the new set point. If you increase Derivative 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 autotune and PID control, see related features in this chapter.

Autotuning with TRU-TUNE+

The TRU-TUNE+ adaptive algorithm will optimize the controller's PID values to improve control of 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 control parameters to optimize responsiveness and stability. The TRUTUNE+ feature does not function for on-off control.

The preferred and quickest method for tuning a loop is to establish initial control settings and continue with the adaptive mode to fine tune the settings.

Setting a controller's control mode to tune starts this two-step tuning process. (See Autotuning in this chapter.) This predictive tune determines initial, rough settings for the PID parameters. Then the loop automatically switches to the adaptive mode which fine tunes the PID parameters.

Once the process variable has been at set point for a suitable period (about 30 minutes for a fast process to roughly two hours for a slower process) and if no further tuning of the PID parameters is desired or needed, TRU-TUNE+ may be turned off. However, keeping 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 TRU-TUNE+ adaptive algorithm, the process, if shut down for any reason, can be restarted in the adaptive control mode.

Turn TRU-TUNE+ on or off with TRU-TUNE+ Enable [t;tUn] (Setup Page, Loop Menu).

Use TRU-TUNE+ Band [t;bnd] (Setup Page, Loop Menu) to set the range above and below the set point in which adaptive tuning will be active. Adjust this parameter only in the unlikely event that the controller is unable to stabilize at the set point with TRU-

TUNE+ Band set to auto (0). This may occur with very fast processes. In that case, set TRU-TUNE+™ Band to a large value, such as 100.

Use TRU-TUNE+ Gain [`t;gn] (Setup Page, Loop

Menu) to adjust the responsiveness of the adaptive tuning calculations. Six settings range from 1, with the most aggressive response and most potential overshoot (highest gain), to 6, with the least aggressive response and least potential for overshoot (lowest gain). The default setting, 3, is recommended for loops with thermocouple feedback and moderate response and overshoot potential.

Before Tuning

Before autotuning, the controller hardware must be installed correctly, and these basic configuration parameters must be set:

• Sensor Type [`SEn] (Setup Page, Analog Input

Menu), and scaling, if required;

• Function [``Fn] (Setup Page, Output Menu) and

scaling, if required.

How to Autotune a Loop

1. Enter the desired set point or one that is in the middle of the expected range of set points that you want to tune for.

2. Enable TRU-TUNE+®.

3. Initiate an autotune. (See Autotuning in this chapter.)

When autotuning is complete, the PID parameters should provide good control. As long as the loop is in the adaptive control mode, TRU-TUNE+® continuously tunes to provide the best possible PID control for the process.

WARNING! During autotuning, the controller sets the output to 100 percent and attempts to drive the process variable toward the set point. Enter a set point and heat and cool power limits that are within the safe operating limits of your system.

Inputs

Calibration Offset

Calibration offset allows a device to compensate for an inaccurate sensor, lead resistance or other factors that affect the input value. A positive offset increases the input value, and a negative offset decreases the input value.

The input offset value can be viewed or changed

with Calibration Offset [`i;CA] (Operations Page, Analog Input Menu).

Calibration

To calibrate an analog input, you will need to provide two electrical signals or resistance loads near the extremes of the range that the application is likely to utilize. See recommended values below:

Sensor Type Low Source High Source

thermocouple 0.000 mV 50.000 mV

millivolts 0.000 mV 50.000 mV

volts 0.000V 10.000V

milliamps 0.000 mA 20.000 mA

100 Ω RTD 50.00 Ω 350.00 Ω

1,000 Ω RTD 500.00 Ω 3,500.00 Ω

Follow these steps for a thermocouple or process input:

1. Apply the low source signal to the input you are calibrating. Measure the signal to ensure it is accurate.

2. Read the value of Electrical Measurement [`Mu] (Factory Page, Calibration Menu) for that input.

3. Calculate the offset value by subtracting this value from the low source signal.

4. Set Electrical Input Offset [ELi;o] (Factory Page, Calibration Menu) for this input to the offset value.

5. Check the Electrical Measurement to see whether it now matches the signal. If it doesn’t match, adjust Electrical Input Offset again.

6. Apply the high source signal to the input. Measure the signal to ensure it is accurate.

7. Read the value of Electrical Measurement for that input.

8. Calculate the gain value by dividing the low source signal by this value.

9. Set Electrical Input Slope [ELi;S] (Factory Page, Calibration Menu) for this input to the calculated gain value.

10. Check the Electrical Measurement to see whether it now matches the signal. If it doesn’t match, adjust Electrical Input Slope again.

Set Electrical Input Offset to 0 and Electrical Input Slope to 1 to restore factory calibration.

Follow these steps for an RTD input:

1. Measure the low source resistance to ensure it is

accurate. Connect the low source resistance to the input you are calibrating.

2. Read the value of Electrical Measurement [`Mu]

(Factory Page, Calibration Menu) for that input.

3. Calculate the offset value by subtracting this value from the low source resistance.

4. Set Electrical Input Offset [ELi;o] (Factory Page, Calibration Menu) for this input to the offset value.

5. Check the Electrical Measurement to see whether it now matches the resistance. If it doesn’t match, adjust Electrical Offset again.

6. Measure the high source resistance to ensure it is accurate. Connect the high source resistance to the input.

7. Read the value of Electrical Measurement for that input.

8. Calculate the gain value by dividing the low source signal by this value.

9. Set Electrical Input Slope [ELi;S] (Factory Page, Calibration Menu) for this input to the calculated gain value.

10. Check the Electrical Measurement to see whether it now matches the signal. If it doesn’t match, adjust Electrical Input Slope again.

Set Electrical Input Offset to 0 and Electrical Input Slope to 1 to restore factory calibration.

Filter Time Constant

Filtering smoothes an input signal by applying a firstorder filter time constant to the signal. 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.

Adjust the filter time interval with Filter Time

[`FiL] (Setup Page, Analog Input Menu).

Example: With a filter value of 0.5 seconds, if the process input value instantly changes from 0 to 100 and remained at 100, the display will indicate 100 after five time constants of the filter value or 2.5 seconds.

Set Point Low Limit and High Limit

The controller constrains the set point to a value between a set point low limit and a set point high limit.

Set the set point limits with Low Set Point [`L;SP]

and High Set Point [`h;SP] (Setup Page, Loop Menu).

There are two sets of set point low and high limits: one for a closed-loop set point, another for an openloop set point.

Scale High and Scale Low

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.

You can create a scale range representing other units for special applications. You can reverse scales from high values to low values for analog input signals that have a reversed action. For example, if 50 psi causes a 4 mA signal and 10 psi causes a 20 mA signal.

Scale low and high low values do not have to match the bounds of the measurement range. These along with range low and high provide for process scaling and can include values not measureable by the controller. Regardless of scaling values, the measured value will be constrained by the electrical measurements of the hardware.

Select the low and high values with Scale Low [`S;Lo] and Scale High [`S;hi]. Select the displayed range with Range Low [`r;Lo] and Range High [`r;hi] (Setup Page, Analog Input Menu).

Range High and Range Low

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.

Control Methods

Output Configuration

Each controller output (1, 2 and 3) 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.

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.

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 Input Error Failure [FAiL] (Setup Page, Loop Menu). The manual mode only allows open-loop control. The EZ-ZONE ST 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 in the upper display and [Attn] in the lower display and respond to the failure according to the setting of Input Error Failure[FAiL]. You can configure the controller to perform a “bumpless” transfer [bPLS], switch power to output a preset fixed level [MAn], 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 the time interval of Time Integral (Operations Page, Loop)

Page 71

prior to sensor failure, and that power level is less than 75 percent.

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.

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.”

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

In an application with one output assigned to heating and another assigned to cooling, each will have a separate proportional parameter. The heating parameter takes effect when the process temperature is lower than the set point, and the cooling parameter takes effect when the process temperature is higher than the set point.

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.

Proportional action ceases when the process value is within the dead band. Integral action continues to bring the process temperature to the set point.

Using a positive dead band value keeps the two systems from fighting each other.

Time

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.

Adjust the integral with Time Integral [``ti] (Op-

erations Page, Loop Menu).

Proportional plus Integral plus Derivative (PID) Control

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

Derivative action is active only when the process value is within twice the proportional value from the set point.

Variable Time Base

Time

Temperature

Temperature reaches Set Point quickly

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, variable-time-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, switching 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.

Soft Start Time

Soft start is an additional feature of phase angle control executed whenever a power increase is called for. The output will gradually increase in power until the final selected power output is reached. The soft start time is the time it takes to go from 0 to 100 percent power.

Alarms

Alarms are activated when the output level, 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.

Alarms do not have to be assigned to an output. Alarms can be monitored and controlled through the front panel or by using software.

Process and 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 or subtracting offset values from the control set point. If the set point changes, the window defined by the alarm set points automatically moves with it.

Select the alarm type with Type [`A;ty] (Setup Page, Alarm Menu).

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.

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

Alarm Silencing

If alarm silencing is on the operator can disable the alarm output while the controller is in an alarm state. The process value or temperature has to enter the normal operating range beyond the hysteresis zone to activate the alarm output function again.

Alarm Blocking

Alarm blocking allows a system to warm up after it has been started up. With alarm blocking on, an alarm is not triggered when the process temperature is initially lower than the alarm low set point or higher than the alarm high set point. The process temperature has to enter the normal operating range beyond the hysteresis zone to activate the alarm function.

If the EZ-ZONE ST has an output that is functioning as a deviation alarm, the alarm is blocked when the set point is changed, until the process value reenters the normal operating range.

Each of the menus in the Factory Page and each of the pages, except the Factory Page, has a security level assigned to it. You can change the read and write access to these menus and pages by using the parameters in the Lockout Menu (Factory Page).

Lockout Menu

There are five parameters in the Lockout Menu (Factory Page):

• Lock Operations Page [LoC;o] sets the security lev- el for the Operations Page. (default: 2)

Note:

The Home and Setup Page lockout levels are fixed

and cannot be changed.

• Lock Profiling Page [LoC;P] sets the security level

for the Profiling Page. (default: 3)

• Password Security Enable [pas;e] will turn on or

Watl o w E Z- Z O NE® S T • 7 3 • Cha p ter 7 Fe a tur e s

The following examples show how the Lockout Menu parameters may be used in applications:

1. You can lock out access to the Operations Page but allow an operator access to the Profile Menu, by changing the default Profile Page and Operations Page security levels. Change Lock Operations Page [LoC;o] to 3 and Lock Profiling Page [LoC;P] to 2. If Set Lockout Security [SLoC] is set to 2 or higher and the Read Lockout Security [rLoC] is set to 2, the Profiling Page and Home Pages can be accessed, and all writable parameters can be written to. Pages with security levels greater than 2 will be locked out (unaccessible).

2 If Set Lockout Security [SLoC] is set to 0 and

Read Lockout Security [rLoC] is set to 5, all pages will be accessible, however, changes will not be allowed on any pages or menus, with one exception: Set Lockout Security [SLoC] can be changed to a higher level.

3. The operator wants to read all the menus and not allow any parameters to be changed.

In the Factory Page, Lockout Menu, set Read

Page 76

Lockout Security [rLoC] to 5 and Set Lockout Security [SLoC] to 0.

4. The operator wants to read and write to the Home Page and Profiling Page, and lock all other pages and menus.

In the Factory Page, Lockout Menu, set Read Lock-

out Security [rLoC] to 2 and Set Lockout Security [SLoC] to 2.

In the Factory Page, Lockout Menu, set Lock Op-

erations Page [LoC;O] to 3 and Lock Profiling Page [LoC;P] to 2.

5. The operator wants to read the Operations Page, Setup Page, Profiling Page, Diagnostics Menu, Lock Menu, Calibration Menu and Custom Menus. The operator also wants to read and write to the Home Page.

In the Factory Page, Lockout Menu, set Read Lock-

out Security [rLoC] to 1 and Set Lockout Security [SLoC] to 5.

In the Factory Page, Lockout Menu, set Lock Op-

erations Page [LoC;O] to 2 and Lock Profiling Page [LoC;P] to 3.

Using Password Security

It is sometimes desirable to apply a higher level of security to the control where a limited number of menus are visible and not providing access to others without a security password. Without the appropriate password those menus will remain inaccessible. If Password Enabled [pas;e] in the Factory Page under the [`loC] Menu is set to on, an overriding Password Security will be in effect. When in effect, the only Pages that a User without a password has visibility to are defined in the Locked Access Level [loC;L] prompt. On the other hand, a User with a password would have visibility restricted by the Read Lockout Security [rloC]. As an example, with Password Enabled and the Locked Access Level [loC;L]set to 1 and [rloC] is set to 3, the available Pages for a User without a password would be limited to the Home and Factory Pages (locked level 1). If the User password is entered all pages would be accessible with the exception of the Setup Page as defined by level 3 access.

How to Enable Password Security Go to the Factory Page by holding down the Infinity ˆ key and the Advance key for approximately six seconds. Once there, push the Down ¯ key one time to

get to the [`loC] menu. Again push the Advance key until the Password Enabled [pas;e] prompt is visible. Lastly, push either the up or down key to turn it on. Once on, 4 new prompts will appear:

1. [loC;l], Locked Access Level (1 to 5) correspond

ing to the lockout table above.

2. [roll], Rolling Password will change the Cus-

tomer Code every time power is cycled.

3. [pas;u], User Password which is needed for a Us-

er to acquire access to the control.

4. [pas;a], Administrator Password which is need-

ed to acquire administrative access to the control.

The Administrator can either change the User and or the Administrator password or leave them in the default state. Once Password Security is enabled they will no longer be visible to anyone other than the Administrator. As can be seen in the formula that follows either the User or Administrator will need to know what those passwords are to acquire a higher level of access to the control. Back out of this menu by pushing the Infinity ˆ key. Once out of the menu, the Password Security will be enabled.

How to Acquire Access to the Control

To acquire access to any inaccessible Pages or Menus, go to the Factory Page and enter the [UloC]menu. Once there follow the steps below:

Note: If Password Security (Password Enabled [pas;e] is

On) is enabled the two prompts mentioned below in the first step will not be visible. If unknown, call the individual or company that originally setup the con trol.

1. Acquire either the User Password [pas;u] or the Administrator Password [pas;a].

2. Push the Advance [Code] prompt will be visible.

Note:

a. If the the Rolling Password is off push the Ad- vance key one more time where the Password [pass] prompt will be displayed. Proceed to

either step 7a or 8a. Pushing the Up ¿ or Down ¯ arrow keys enter either the User or Adminis- trator Password. Once entered, push and hold the Infinity ˆ key for two seconds to return to the Home Page.

b. If the Rolling Password [roll] was turned on proceed on through steps 3 - 9.

3. Assuming the Public Key [Code] prompt is still visible on the face of the control simply push the Advance Key‰to proceed to the Password [pass] prompt. If not find your way back to the Factory Page as described above.

4. Execute the calculation defined below (7b or 8b) for either the User or Administrator.

5. Enter the result of the calculation in the upper dis- play by using the Up ¿ or Down ¯ arrow keys or use EZ-ZONE Confgurator Software.

6. Exit the Factory Page by pushing and holding the Infinity ˆ key for two seconds.

Formulas used by the User and the Administrator to calculate the Password follows:

Differences Between a User Without Password, User With Password and Administrator

eter’s actual value. If it’s a writable parameter, writing to its working register will change the parameter’s actual value.

As an example, Modbus register 360 contains the Analog Input 1 Process Value (See Operations Page, Analog Input Menu). If the value 360 is loaded into Assembly Definition Address 91, the process value sensed by analog input 1 will also be stored in Modbus registers 250 and 251. Note that by default this parameter is also stored in working registers 240 and 241 as well.

The table (See Appendix: Modbus Programmable Memory Blocks) identified as "Assembly Definition Addresses and Assembly Working Addresses" reflects the assemblies and their associated addresses.

- A User with a password is restricted by the Read Lockout Security [rloC] never having ac- cess to the Lock Menu [`loC].

- An Administrator is restricted according to the Read Lockout Security [rloC] however, the Ad- ministrator has access to the Lock Menu where the Read Lockout can be changed.

Modbus - Using Programmable Memory Blocks

When using the Modbus protocol, the ST control features a block of addresses that can be configured by the user to provide direct access to a list of 40 user configured parameters. This allows the user easy access to this customized list by reading from or writing to a contiguous block of registers.

Note:

To use the User Programmable Memory Blocks feature, Map 2 must be selected. Change the mapping [map]via the Setup Page under the [Com] Menu.

To acquire a better understanding of the tables found in the back of this manual (See Appendix: Modbus

Programmable Memory Blocks) please read through

the text below which defines the column headers used.

Assembly Definition Addresses

- Fixed addresses used to define the parameter

that will be stored in the "Working Addresses", which may also be referred to as a pointer. The value stored in these addresses will reflect (point to) the Modbus address of a parameter within the ST control.

Assembly Working Addresses

- Fixed addresses directly related to their associ-

ated "Assembly Definition Addresses" (i.e., As- sembly Working Addresses 200 & 201 will assume the parameter pointed to by Assembly Definition Addresses 40 & 41).

When the Modbus address of a target parameter is stored in an "Assembly Definition Address" its corresponding working address will return that param-

CIP - Communications Capabilities

CIP Communications Methodology

To communicate with the ST using CIP an RUI/GTW must be used. Reading or writing when using CIP can be accomplished via explicit and or implicit communications. Explicit communications usually requires the use of a message instruction but there are other ways to do this as well. Implicit communications is also commonly referred to as polled communications. When using implicit communications there is an I/O assembly that would be read or written to; the assemblies are embedded into the ST firmware. Watlow refers to these assemblies as the T to O (Target to Originator) and the O to T (Originator to Target) assemblies where the Target is always the ST and the Originator is the PLC or master on the network. The O to T assembly is made up of 20 (32 bit) members that are user configurable where the T to O assembly consists of 21 (32 bit) members. The first member of the T to O assembly is called the Device Status and cannot be changed. However, the 20 members that follow it are user configurable (See Appendix: CIP Implicit O to T

(Originator to Target) Assembly Structure and CIP

Implicit T to O (Target to Originator) Assembly Struc-

ture).

To change any given member of either assembly simply write the new class, instance and attribute to the member location of choice. As an example, if it were desired to change the 14th member of the O to T assembly from the default parameter (Heat Proportional Band) to Limit Clear Request (see Operations Page, Limit Menu) write the value of 0x70, 0x01 and 0x01 (Class, Instance and Attribute respectively) to 0x77, 0x01 and 0x0E. Once executed, writing a value of zero to this member will reset a limit assuming the condition that caused it is no longer present.

Software Configuration

Using EZ-ZONE® Configurator Software

To enable a user to configure the ST control using a personal computer (PC), Watlow has provided free software for your use. If you have not yet obtained a copy of this software insert the CD (Controller Support Tools) into your CD drive and install the software. Alternatively, if you are viewing this document electronically and have a connection to the internet simply click on the link below and download the software from the Watlow web site free of charge.

http://www.watlow.com/products/software/zone_config.cfm

Once the software is installed double click on the EZ-ZONE Configurator icon placed on your desktop during the installation process. If you cannot find the icon follow the steps below to run the software:

1. Move your mouse to the "Start" button

2. Place the mouse over "All Programs"

3. Navigate to the "Watlow" folder and then the sub- folder "EZ-ZONE Configurator"

4. Click on EZ-ZONE Configurator to run.

The first screen that will appear is shown below.

define the communications port on the PC to use.

The available options allow the user to select "Try them all" or to use a specific known communications port. After installation of your converter if you are not sure which communications port was allocated select "Try them all" and then click next. The screen to follow shows that the software is scanning for devices on the network and that progress is being made.

When complete the software will display all of the If the PC is already physically connected to the EZZONE ST control click the next button to go on-line.

Note:

When establishing communications from PC to the EZ-ZONE ST control an interface converter will be required. The Standard Bus network uses EIA-485 as the interface. Most PCs today would require a USB to EIA-485 converter. However, some PCs may still be equipped with EIA-232 ports, therefore an EIA-232 to EIA-485 converter would be required.

As can be seen in the above screen shot the software provides the user with the option of downloading a previously saved configuration as well as the ability to create a configuration off-line to download later. The screen shots that follow will take the user online.

After clicking the next button above it is necessary to

In the previous screen shot the ST is shown highlighted to bring greater clarity to the control in focus. Any EZ-ZONE device on the network will appear in this window and would be available for the purpose of configuration. After clicking on the control of choice simply click the next button once again. The next screen appears below.

alternative, clicking on the negative symbol next to

brought to an individual parameter (single click of

In the screen shot above notice that the device part number is clearly displayed at the top of the page (yellow highlight added for emphasis). When multiple EZ-ZONE devices are on the network it is important that the part number be noted prior to configuring so as to avoid making unwanted configuration changes to another control.

Looking closely at the left hand column (Parameter Menus) notice that it displays all of the available menus and associated parameters within the control. The menu structure as laid out within this software follows:

- Setup

- Operations

- Factory

- Profile

Navigating from one menu to the next is easy and clearly visible. Simply slide the scroll bar up or down

mouse) as is the case for Analog Input 1 in the left

column, all that can be setup related to that param-

eter will appear in the center column. The grayed

out fields in the center column simply mean that this

does not apply for the type of sensor selected. As an

example, notice that when RTD is selected, TC Lin-

earization does not apply and is therefore grayed out.

To speed up the process of configuration notice that

at the bottom of the center column there is an option

to copy settings. If Analog Input 1 and 2 are the same

type of sensor click on "Copy Settings" where a copy

from to copy to dialog box will appear allowing for

quick duplication of all settings.

Notice too, that by clicking on any of those items in

the center column that context sensitive help will

appear for that particular item in the right hand col-

umn.

Lastly, when the configuration is complete click the "Finish" button at the bottom right of the previous screen shot. The screen that follows this action can be seen below.

Although the ST control now contains the configuration (because the previous discussion focused on doing the configuration on-line) it is suggested that after the configuration process is completed that the user save this file on the PC for future use. If for some reason someone inadvertently changed a setting without understanding the impact it would be easy and perhaps faster to download a saved configuration back to the control versus trying to figure out what was changed.

Of course, there is an option to exit without saving a copy to the local hard drive.

After selecting Save above click the "Finish" button once again. The screen below will than appear.

When saving the configuration note the location where the file will be placed (Saved in) and enter the file name (File name) as well. The default path for saved files follows:

\Program Files\Watlow\EZ-ZONE CONFIGURATOR\Saved Configurations

The user can save the file to any folder of choice.
