Chapter 1 Over view
A Conceptual View of the PM
The flexibility of the PM’s software and hardware allows a large range of configurations. Acquiring a better
understanding of the EZ-ZONE ® family controller’s and their 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 three parts: inputs, procedures and outputs. Information flows
from an input to a procedure to an output when the controller is properly configured. A PM limit controller
can carry out several procedures at the same tim, for instance, monitoring for several different alarm situations, monitoring and acting upon digital inputs and driving output devices such as lights and contactors.
Each process needs to be thought out carefully and the controller’s inputs, procedures and outputs set up
properly.
Inputs
The inputs provide the information that any given programmed procedure can act upon. Simply stated, this
information may come from an operator pushing a button or from a sensor monitoring the temperature of a
part being heated or cooled.
Each analog input typically uses a thermocouple or RTD to read the process temperature. 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 PM with digital input/output hardware
includes two sets of terminals where each of which can be used as either an input or an output. Each pair of
terminals must be configured to function as either an input or output with the direction parameter in the
Digital Input/Output Menu (Setup Page).
The Function or EZ Key/s (PM4/6/8/9 only) on the front panel of the PM also operates as a digital input by
toggling the function assigned to it in the Digital Input Function parameter in the Function Key Menu (Setup Page).
Functions
Functions use input signals to calculate a value. A function may be as simple as reading a digital input to set
a state to true or false, or reading a temperature to set an alarm state to on or off. Or, if a failure with the
primary sensing device should occur the limit could trip a contactor removing power from the heating element to avoid damaging the load.
To set up a function, it’s important to tell it what source, or instance, to use. For example, if the control is
equipped with digital inputs they can be configured as an alarm. If configured as such the next step would
be to define which of the four available alarm instances this digital input would be tied to. So, in this example the source would be Digital Input 5 or 6 where the instance would be selected as 1, 2, 3, or 4 corresponding to the alarm instances.
Keep in mind that a function is a user-programmed internal process that does not execute any action outside
of the controller. To have any effect outside of the controller, an output must be configured to respond to a
function.
Outputs
Outputs can perform various functions or actions in response to information provided by a function, such as
removal of the control voltage to a contactor; turning a light on or off; unlocking a door; or turning on a buzzer.
Assign an output to a Function in the Output Menu or Digital Input/Output Menu. Then select which instance of that function will drive the selected output. For example, in using a Limit Control an output can be
configured to respond to an alarm, i.e., (instance 4) or to a limit condition.
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 events are internal states that are set by the digital inputs. Digital Input 5 provides the state of input
event 1, and Digital Input 6 provides the state of input event 2. The setting of Digital Input Function (Setup
Page, Digital Input/Output Menu) does not change the relationship between the input and the event. An input will still control the input event state, even if Digital Input Function is set to None.

Installation
1. Make the panel cutout using the mounting template dimensions in this chapter.
Insert the case assembly into the panel cutout.
2. While pressing the case assembly firmly against the panel,
slide the mounting collar over the back of the controller.
If the installation does not require a NEMA 4X seal, simply
slide together until the gasket is compressed.
3. For a NEMA 4X (UL50, IP65) seal, alternately place and
push the blade of a screwdriver against each of the the four
corners of the mounting collar assembly. Apply pressure to
the face of the controller while pushing with the screwdriver.
Don't be afraid to apply enough pressure to properly install
the controller. The seal system is compressed more by mating the mounting collar tighter to the front panel (see pictures above). If you can move the case assembly back and
forth in the cutout, you do not have a proper seal. The tabs
on each side of the mounting collar have teeth that latch into the ridges on the sides of the controller.
Each tooth is staggered at a different depth from the front so that only one of the tabs, on each side, is
locked onto the ridges at a time.
Slide the mounting collar over the back of the
controller.
Place the blade of a screwdriver in any
of the corner of the mounting collar assembly.
Note:
There is a graduated measurement difference between the upper and lower half of the display to the panel.
In order to meet the seal requirements mentioned above, ensure that the distance from the front of the top
half of the display to the panel is 16 mm (0.630 in.) or less, and the distance from the front of the bottom
half and the panel is 13.3 mm (0.525 in.) or less.

Removing the Mounted Controller from Its Case
1. From the controller's face, pull out the tabs on each side until you hear it click.
Pull out the tab on each side until you hear it click.
Grab the unit above and below the face and pull
forward.
2. Grab the unit above and below the face with two hands and pull the unit out. On the PM4/8/9 controls
slide a screwdriver under the pry tabs and turn.
Returning the Controller to its Case
1. Ensure that the orientation of the controller is correct and slide it back into the housing.
Note:
The controller is keyed so if it feels that it will not slide back in do not force it. Check the orientation again
and reinsert after correcting.
2. Using your thumbs push on either side of the controller until both latches click.

Chapter 4: Home Page
Default Home Page Parameters
Watlow’s patented user-defined menu system improves operational efficiency. The user-defined Home Page
provides you with a shortcut to monitor or change the parameter values that you use most often. The default
Home Page is shown on the following page. When a parameter normally located in the Setup Page or Operations Page is placed in the Home Page, it is accessible through both. If you change a parameter in the Home
Page, it is automatically changed in its original page. If you change a parameter in its original page it is automatically changed in the Home Page.
The Attention [Attn] parameter appears only if there is an active message. An example of an active message could be that Alarm 1 High occurred where the display would flash [Attn] on the bottom display and
[al; h1] on top.
Use the Advance key ‰to step through the other parameters. When not in pairs the parameter prompt
will appear in the lower display, and the parameter value will appear in the upper display. You can use the
Up ¿ or Down ¯ keys to change the value of writable parameters, just as you would in any other menu.
If a sensor failure has occurred, dashed lines [----] will appear in the upper display and [ fail] in the
lower display. This would also cause the limit to trip as well.
Changing the Set Point
From the default Home Page the Limit set points (high and or low) can be changed. If the Limit is set up for
high and low limits push the Advance ‰ key one time and the Low Limit Set Point [ll;51] prompt will appear in the lower display while the current set point will be displayed above. Pushing the Up ¿ or Down
¯ keys will change the set point. Once done, simply push the Advance ‰ key to display the High Limit Set
Point [lh;51] will appear below and the current Maximum Set Point will be displayed above. Again, to
change simply push the Up and Down arrow keys.
Modifying the Home Page
Follow the steps below to modify the Home Page:
1. Push and hold the Advance ‰ key and the Infinity ˆ key for approximately six seconds.
Upon entering the Factory Page the first menu will be the Custom Menu [Cust] .
2. Push the Advance ‰ key where the lower display will show [Cust] and the upper display will show [1] .
3. Push the Advance ‰ button where the prompt for the Process Value [aC; p u] will be displayed on top and
Parameter [`par] in the bottom.
There are twenty positions available that can be customized.
4. Pushing the Up ¿ or Down ¯ arrow keys will allow for a customized selection to be made (see list of
available parameters below).

Modifying the Display Pairs
The Home Page, being a customized list of as many as 20 parameters can be configured in pairs of up to 10
via the Display Pairs [d;prs] prompt.
Note:
For firmware release 11.0 and above the Display Pairs prompt can be found in the Setup Page under the
Global Menu [glbl].
For firmware releases below revision 11.0 this prompt can be found in the Factory Page under the Diagnostic Menu [diag].
The listing in the table that follows represents the Limit default Home Page. It is important to note that some
of the prompts shown may not appear simply because the feature is not being used or is turned off. As an example, the prompt shown in position 3 (Low Limit Set Point) will not appear unless the Sides [`l; sd ] is set
up for Both (high and low) or low in the Setup Page under the Limit Menu.

Note:
When the Limit is in a default state (as shipped from factory), the display will flash where the top display
will show the Process Value and [Li;hi] and the bottom will display [attn] and [FAIL].
As stated above, the user can define ten pairs of prompts to appear on the display every time the Advance ‰
key is pushed. In a default state the Display Pairs [d;prs] prompt is equal to one with the first pair displayed
as is defined in the Home Page table above. If the Display Pairs prompt were to be changed to two, pushing
the Advance key one time would cause the display to show the Low Limit Set Point on the top and the HIgh
Limit Set Point on the bottom reflecting position 3 and 4 respectively.
Note::
Both of these parameters are writable and being paired in this manner only the HIgh Limit Set Point can
be changed. Pairing two writable prompts will only allow for the bottom one to be changed. On the other
hand, if a writable value is placed on the upper display and is paired with another read only parameter on
the lower display, the arrow keys affect the setting of the upper display.
The display can be configured to scroll through the Display Pairs by going to the Setup Page under the Global Menu and changing the Display Time [`d ; ti] prompt to something greater than 0. If set to 2, the display
will scroll through the pairs every 2 seconds starting with Custom Menu Pair 1 and 2, 3 and 4, etc...

Conventions Used in the Menu Pages
To better understand the menu pages that follow review the naming conventions used. When encountered
throughout this document, the word "default" implies as shipped from the factory. Each page (Operations,
Setup, Profile and Factory) and their associated menus have identical headers defined below:
Header Name
Definition
Display
Visually displayed information from the control.
Parameter Name
Describes the function of the given parameter.
Range
Defines options available for this prompt, i.e., min/max values (numerical), yes/no, etc... (further explanation below).
Default
Values as delivered from the factory.
Parameter Appears in Menu When
Conditions required for parameter to appear in menu.
Modbus Relative Address
Identifies unique parameters using either the Modbus RTU or Modbus TCP protocols (further explanation below).
CIP (Common Industrial Protocol)
Identifies unique parameters using either the DeviceNet or EtherNet/IP protocol (further explanation below).
Profibus Index
Identifies unique parameters using Profibus DP protocol (further explanation below).
Parameter ID
Identifies unique parameters used with other software such as, LabVIEW.
uint = Unsigned 16 bit integer
dint = long, 32-bit
string = ASCII (8 bits per character)
Data Type R/W
float =IEEE 754 32-bit
RWES= Readable
Writable
EEPROM (saved)
User Set (saved)
Display
Visual information from the control is displayed to the observer using a fairly standard 7 segment display.
Due to the use of this technology, several characters displayed need some interpretation, see the list below:
[1] = 1
[0] = 0
[i] = i
[r] = r
[2] = 2
[a] = A
[j ] = J
[s] = S
[3] = 3
[ b] = b
[H] = K
[ t] = t
[4] = 4
[c] , [C] = c
[l] = L
[U] = u
[5] = 5
[d ] = d
[m] = M
[u] = v
[6] = 6
[ e] = E

[o] = o
[y ] = y
[8] = 8
[g ] = g
[ p] = P
[2] = Z
[9] = 9
[ h] = h
[q ] = q
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. To turn
the sensor off simply write the value of 62 (off) to Modbus register 400369 and send that value to the control.

Chapter 4 Home Page
Communication Protocols
When using a communications protocol in conjunction with the EZ-ZONE PML there may be two possible
ports (instances) used. Port 1 or instance 1 is always dedicated to Standard Bus communications. This same
instance can also be used for Modbus RTU if ordered. Depending on the controller part number port 2 (instance 2) can be used with Modbus, CIP and Profibus. For further information read through the remainder of
this section.
Modbus RTU & 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 465535 (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 Analog Input Value. Find
the column identified in the header as Modbus Relative Address and notice that it lists register 360. Because
this parameter is a float it 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 7.00 and above new functions where introduced into the EZ-ZONE
product line. With the introduction of these new functions there was a reorganization of Modbus registers.
Notice in the column identified as Modbus Relative Address the reference to Map 1 and Map 2 registers for
each of the various parameters. To be backwards compatible in your programming use Map 1 registers. To
be able to implement new functions in the Limit when and if they become available use Map 2 registers.
The Data Map [map] for Modbus registers 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 contain wording pertaining to an offset.
Several parameters in the control contain more than one instance; such as, profiles (4), alarms (4), etc... The
Modbus register shown always represents instance one. Take for an example the Alarm Silence parameter
found in the Setup Page under the Alarm menu. Instance one of Map 1 is shown as address 1490 and +50 is
identified as the offset to the next instance. If there was a desire to read or write to instance 3 simply add
100 to 1490 to find its address, in this case, the instance 3 address for Alarm Silence is 1590.
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.

Chapter 8 Features
Changing PM Limit Model Number to PM User Mode
EZ-ZONE PM Limit firmware revisions of 13 and above allow the user to switch between a PM Limit control
to a PM Express Limit. Switching to a PM Express Limit eliminates the complexity of the PM Limit control
by allowing the user to operate with a simplified menu structure.
Note:
When switching from a Limit control to an Express version, optional PM hardware (even though installed)
and firmware features not available in a PM Express will no longer work. To see exactly what is impacted
by this change, compare the chart below to the ordering information page in this document.

How to Change the PM Control Model Number to User Mode
1. Enter Factory Page [FCty], Calibration Menu [`CAL] via front panel by pressing the Infinity ˆ or Reset
Key and the Advance Key ‰ together or using EZ-ZONE Configurator software.
2. Once there, use the Advance Key ‰ to navigate to the Part Number [``Pn] prompt (green display). The
red display will show factory [fCtY] indicating the factory model number as shown on the decal located
on the side of the control is currently in effect.
3. Push the Advance Key ‰, Public Key [Code] prompt will be displayed in the green display and the number [4999] in the red display.
4. Using the up or down Arrow Keys enter [2501] and push the Advance Key ‰ to execute the change. The
controller will reboot and the new controller model number is in effect. All previous settings are lost and
the controller must be reprogrammed for the application. Be sure to label the controller with the new
model number for future reference.
Note:
As noted above, when switching from a PM Standard to a PM Express version, optional hardware (even
though installed) may no longer work, and all settings will default to those of the selected model.
How to Restore Original Factory Mode PM Model Number
1. Enter Factory Page [FCty], Calibration Menu [`CAL] via front panel by pressing the Infinity ˆ or Reset

2. Once there, use the Advance Key ‰ to navigate to the Part Number [``Pn] prompt (green display). The
red display will show user [USEr] indicating the user’s selected model number is currently in effect.
3. Push the Advance Key ‰, Public Key [Code] prompt will be displayed in the green display and the number [4999] in the red display.
4. Using the up or down arrow keys enter [~606] and push the Advance Key ‰ to execute the change. The
controller will reboot and the new controller model number is in effect. All previous settings are lost and
the controller must be reprogrammed for the application. Be sure to label the controller with the new
model number for future reference.
Note:
When switching from a PM Express back to the original model number all original optional hardware will
again be enabled for use (assuming all original hardware is still installed). Also, when executing this step
the controller will be factory defaulted back to the original model number (as shown on the side of the control) at zone address 1. This appropriate User's Guide would once again apply to this control.
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 Restore Settings From [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 Function Key can also be configured to restore user settings.
Note:
Only perform the above procedure when you are sure that all the correct settings are programmed into the
controller. Saving the settings overwrites any previously saved collection of settings. Be sure to document all
the controller settings.
Note:
The control can also be brought back to the factory defaults. When doing so all previous user settings will be
deleted, this would include user setting 1 and 2 along with any previously configured I/O assemblies.
Programming the Home Page
Watlow’s patented user-defined menu system improves operational efficiency. The user-defined Home Page
provides you with a shortcut to monitor or change the parameter values that you use most often.
You can create your own Home Page with as many as 20 of the active parameters. When a parameter normally located in the Setup Page or Operations Page is placed in the Home Page, it is accessible through both.
If you change a parameter in the Home Page, it is automatically changed in its original page. If you change a
parameter in its original page it is automatically changed in the Home Page.
The default parameters will automatically appear in the Home Page.
Change the list of parameters in the Home Page from the Custom Menu [CUSt] (Factory Page).
Inputs
Calibration Offset
Temperature Reading

Temperature
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).
Negative Calibration Offset will

Before performing any calibration procedure, verify that the displayed readings are not within published
specifications by inputting a known value from a precision source to the analog input. Next, subtract the displayed value with the known value and compare this difference to the published accuracy range specification
for that type of input.
Use of the Calibration Offset [`i;CA] parameter found in the Operations Page [oPEr] , Analog Input
Menu [``Ai] shifts the readings across the entire displayed range by the offset value. Use this parameter to
compensate for sensor error or sensor placement error. Typically this value is set to zero.
Equipment required while performing calibration: Obtain a precision source for millivolts, volts, milliamperes or resistance depending on the sensor type to be calibrated. Use copper wire only to connect the precision source to the controller’s input. Keep leads between the precision source and controller as short as possible to minimize error. In addition, a precision volt/ohm meter capable of reading values to 4 decimal places
or better is recommended. Prior to calibration, connect this volt/ohm meter to the precision source to verify
accuracy.
Actual input values do NOT have to be exactly the recommended values, but it IS critical that the actual
value of the signal connected to the controller be accurately known to at least four digits.
Calibration of Analog Inputs:
To calibrate an analog input, you will need to provide a source of two electrical signals or resistance values
near the extremes of the range that the application is likely to utilize. See recommended values below:

Note:
The user may only calibrate one sensor type. If the calibrator interferences with open thermocouple detection, set Sensor Type [`SEn] in Setup Page [`SEt], Analog Input Menu [``Ai] to millivolt [`Mu] instead
of Thermocouple [``tC] to avoid interference between the calibrator and open thermocouple detect circuit
for the duration of the calibration process. Be sure to set sensor type back to the thermocouple type utilized.
1. Disconnect the sensor from the controller.
2. Record the Calibration Offset [`i;CA] parameter value in the Operations Page [oPEr] , Analog Input
Menu [``Ai] then set value to zero.
3. Wire the precision source to the appropriate controller input terminals to be calibrated. Do not have any
other wires connected to the input terminals. Please refer to the Install and Wiring section of this manual for the appropriate connections.
4. Ensure the controller sensor type is programmed to the appropriate Sensor Type [`SEn] to be utilized in
the Setup Page [`SEt] , Analog Input Menu [``Ai] .
5. Enter Factory Page [FCty ] , Calibration Menu [`CAL] via RUI or EZ-ZONE Configurator Software.
6. Select the Calibration [CAL] input instance to be calibrated. This corresponds to the analog input to be
calibrated.
7. Set Electrical Input Slope [ELi;S] to 1.000 and Electrical Input Offset [ELi; o ] to 0.000 (this will cancel
any prior user calibration values)
8. Input a Precision Source Low value. Read Electrical Measurement value [`Mu] of controller via
EZ-Configurator or RUI. This will be referred to as Electrical Measured Low. Record low value

13. Enter the calculated Electrical Input Slope [ELi;S] and Electrical Input Offset [ELi; o ] into the controller.
14. Exit calibration menu.
15. Validate calibration process by utilizing a calibrator to the analog input.
16. Enter calibration offset as recorded in step 2 if required to compensate for sensor error.
Setting Electrical Input Slope [ELi;S] to 1.000 and Electrical Input Offset [ELi; o ] to 0.000, restores factory
calibration as shipped from factory.
Filter Time Constant
Filtering smoothes an input signal by applying a first-order 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.

Sensor Selection
You need to configure the controller to match the input device, which is normally a thermocouple, RTD or
process transmitter. When you select an input device, the controller automatically sets the input linearization
to match the sensor. It also sets high and low limits, which in turn limit the set point range-high and rangelow values.
Select the sensor type with Sensor Type [`Sen] (Setup Page, Analog Input Menu).
Note:
The EZ-ZONE PM does not have an open-sensor detection feature for process inputs.
Minimum Set Point and High Limit
The controller constrains the Limit set point to a value between the Minimum Set Point and the Maximum
Set Point.
Set the set point range with Minimum Set Point [sp;ll] and Set Point HighLimit [sp;lh] (Setup Page,
Loop Menu).

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.
Select the low and high values with Range Low [`r;Lo] and Range High [`r;hi] (Setup Page, Analog Input Menu).
Outputs
Retransmitting a Process Value or Set Point
Output Scale
The retransmit feature allows a process output to provide an analog signal that represents the set point or
process value. The signal may serve as a remote set point for another controller or as an input for a chart recorder documenting system performance over time.
In choosing the type of retransmit signal the operator must take into account the input impedance of the
device to be retransmitted to and the required signal type, either voltage or milliamps.
Typically applications might use
Range High
the retransmit option to record one of
the variables with a chart recorder or
to generate a set point for other controls in a multi-zone application.
Outputs 1 and 3 can be ordered
as process outputs and used to retransmit. Select retransmit [rMt] as
the Output Function [``Fn] (Setup
Page, Output Menu). Set the output
to volts [uoLt] or milliamps [`MA]
with Output Type [`o;ty]. Select the Range Low

Set the range of the process output with Scale Low [`S;Lo] and Scale High [`S;hi]. Scale the retransmit

When the retransmit source is at the Range Low value, the retransmit output will be at its Scale Low value. When the retransmit source is at the Range High value, the retransmit output will be at its Scale High
value.

Resetting a Tripped Limit
Output 2 will always be a Form A (normally open) Mechanical Relay and it will always be internally tied to
the limit function. When the limit is in a safe state the internal coil for this relay will be energized, therefore
the relay will be closed. When a condition occurs that causes the limit to trip, the internal coil will deengerize causing the relay to latch open. When the condition that caused the limit to trip has been resolved, the relay will remain latched open until manually reset. The process to reset a latched limit can be different from
control to control and is dependent upon the controller firmware version.
To check the firmware revision of your control do one of the following:
1. Cycle power to the control while observing the number in the top display (this momentary numerical display reflects the current installed firmware version).
2. Navigate to the Factory Page by simultaneously pushing and holding the Advance Key ‰ and the Reset
Key
for approximately 8 seconds and then use the up or down arrow key to navigate to the Diagnostic
Menu. Once there, push the Advance Key twice where the revision [`reu] will be shown in the lower display and the upper display will indicate the current firmware revision.
RESET
Prior to firmware release 11.0:
1. Push the Reset Key
2. Configure a digital input with the Action Function set to Limit Reset (navigate to the Setup Page under
the Digital I/O Menu).
RESET
3. Use a field bus protocol, i.e., Modbus, EtherNet/IP, etc...where a value of zero would be written to the associated address (navigate to the Operations Page and look for Clear Limit under the Limit Menu to find
appropriate address).
4. Cycle the power to the controller.
Firmware release 11.0 and above:
1. Push the Reset Key
2. Follow the steps below:
RESET
2a. Navigate to the Setup Page and then the Limit Menu
2b. Set Source Function A to the desired device that will reset the limit (Digital I/O or Function Key)
2c. Define the Source Instance
3. Use a field bus protocol, i.e., Modbus, EtherNet/IP, etc...where a value of zero would be written to the associated address (navigate to the Operations Page and look for Clear Limit under the Limit Menu to find
appropriate address).
4. Cycle the power to the controller.
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 Alarms
A process alarm uses one or two absolute set points to define an alarm condition.
Select the Type with Type [`A;ty] (Setup Page, Alarm Menu).
Alarm Set Points
The High Set Point defines the process value or temperature that will trigger a high side alarm. It must be
higher than the Low Set Point and lower than the high limit of the sensor range.
The Low Set Point defines the temperature that will trigger a low side alarm. It must be lower than the
High Set Point and higher than the low limit of the sensor range.
View or change alarm set points with Low Set Point [`A;Lo] and High Set Point [`A;hi] (Operations Page,

Using Lockout and Password Security
If unintentional changes to parameter settings might raise safety concerns or lead to downtime, you can use
the lockout feature to make them more secure. There are two methods of lockout that can be deployed, both of
which are accessible from the Factory Page.
Method 1-Change the value of the Read Lock [rloc] (1 to 5) and Set Lock [sloc] (0 to 5) prompts where
the higher the value or setting for each translates to a higher security clearance (greater access).
Method 2-Enable Password Security [ pas ; e ] and then modify the Lock Level [loC; l] value which ranges
from 1 to 5. See the section entitled Using Lockout Method 2 for more detail.
Using Lockout Method 1 (Read and Set Lock)
All Pages have security levels assigned where two of those cannot be changed (Home and Setup). Defaults
(factory settings) for each are shown below:
- Home Page = 1
- Operations Page = 2 (changeable to 1, 2 or 3)
- Setup Page = 4
- Factory Page = 5*
*The Factory Page is always visible where all menus within it may or may not be visible/writable. See tables
below for further detail.
The table below represents the various levels of lockout for the Set Lockout Security prompt [SLoC] and
the Read Lockout Security prompt [rLoC]. Looking at the table, "Y" equates to yes (can write/read) where
"N" equates to no (cannot write/read). The colored cells simply differentiate one level from the next As stated
previously, the Set Lockout has 6 levels (0 to 5) of security where the Read Lockout has 5 (1 to 5). Therefore,
level "0" applies to Set Lockout only.

An example of Method 1 lockout usage could be that an operator wants read access to all pages while allowing read/write access to the Home Page and the Lockout Menu only.
1. Press and hold the Advance and Infinity keys for approximately 6 seconds to enter the Factory Page
2. Navigate to the [`LoC] Menu using the Up or Down arrow keys
3. Using the green Advance key navigate to the Read Lockout Security [rLoC] and change it to 5
4. Push the green Advance key and navigate to the and Set Lockout Security [SLoC] changing it to 1

Using Lockout Method 2 (Password Enable)
It is sometimes desirable to apply a higher level of security to the control where a password would be required
to access the control. 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. Without the appropriate password, specified menus will remain inaccessible. Page and Menu access is 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
Follow the steps below:
1. Go to the Factory Page by holding down the Reset
onds.
RESET
key and the Advance ‰ key for approximately six sec-
2. 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.
3. Push either the up or down key to turn it on. Once on, 4 new prompts will appear:
a. [loC; l] , Locked Access Level (1 to 5) corresponding to the lockout table above.
b. [roll] , Rolling Password will change the Cus-tomer Code every time power is cycled.
c. [ pas ; u ] , User Password which is needed for a Us-er to acquire access to the control.
d. [ 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. In other words the Lock Menu [`loC] is not available to a User. 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 the password is unknown, call the individual or company that originally
setup the control.
1. Acquire either the User Password [ pas ; u ] or the Administrator Password [ pas ; a ] .
2. Push the Advance ‰ key one time where the Code [Cod e] prompt will be visible.

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 display play by using the Up ¿ and Down ¯ arrow keys or
use EZ-ZONE Confgurator Software.
6. Exit the Factory Page by pushing and holding the Reset

a. If Rolling Password [roll] is Off, Password [ pass] equals User Password [ pas ; u ] .
b. If Rolling Password [roll] is On, Password [ pass] equals: ( [ pas ; u ] x code) Mod 929 + 70
8. Administrator
a. If Rolling Password [roll] is Off, Password [ pass] equals User Password [ pas ; a ] .
b. If Rolling Password [roll] is On, Password [ pass] equals: ([ pas ; a ] x code) Mod 997 + 1000
Modbus - Using Programmable Memory Blocks
When using the Modbus RTU or Modbus TCP protocols, the PM 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.
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 PM controller.
Assembly Working Addresses
- Fixed addresses directly related to their associated "Assembly Definition Addresses" (i.e., Assembly 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 parameter’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.

CIP - Communications Capabilities
With the introduction of CIP a user can now collect data, configure a device and control industrial devices.
CIP is an open protocol at the application layer fully managed by the Open DeviceNet Vendors Association
(ODVA, http://www.odva.org). Being that this is an open protocol there are many independent vendors offering a wide array of devices to the end user. CIP provides the ability to communicate utilizing both implicit
messaging (real-time I/O messaging), and explicit messaging (information/configuration messaging). For implicit communications using a PLC, simply configure the PM assembly size into the I/O structure of the PLC
(See: CIP Implicit Assemblie Structures). The assembly structures can also be changed by the user.
Explicit communications requires the use of specific addressing information. DeviceNet requires that the
node address be specified where EtherNet/IP requires just the Class, Instance and Attribute.
• Node address or MAC ID (0 - 63, DeviceNet only)
• Class ID (1 to 255)
• Instance ID (0 to 255)
• Attribute ID (1 to 255)
EtherNet/IP and DeviceNet are both based on CIP 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 Watlow
implementation of CIP does not support connected explicit messages but fully supports unconnected explicit
messaging.
Rockwell Automation (RA) developed the DF1 serial protocol within the framework of the PCCC application protocol. With the introduction of CIP, the PCCC protocol was encapsulated within it to enable continued
communication over Ethernet to the legacy RA programmable controllers, e.g., SLC, Micrologic and PLC-5
controllers equipped with Ethernet capabilities. The Watlow implementation of CIP also supports the PCCC
protocol.
EtherNet/IP (Industrial Protocol) is a network communication standard capable of handling large amounts
of data at speeds of 10 Mbps or 100 Mbps, and at up to 1,500 bytes per packet. It makes use of standard offthe-shelf Ethernet chip sets and the currently installed physical media (hardware connections). DeviceNet
was the first field bus offering of the ODVA group and has been around for many years. DeviceNet can communicate at 125, 250 and 500 kilobytes per second with a maximum limitation of 64 nodes (0 to 63) on the
network.
Note:
If the control is brought back to the factory defaults the user configured assemblies will be overwritten.
Note:
The maximum number of implicit input/output members using DeviceNet is 200. When using EtherNet/IP
the maximum is 100.
CIP Implicit Assemblies
Communications using CIP (EtherNet/IP and DeviceNet) can be accomplished with any PM Integrated control equipped with either DeviceNet or EtherNet/IP communications cards. As was already mentioned, reading or writing when using CIP can be accomplished via explicit and or implicit communications. Explicit communications are usually executed via a message instruction within the PLC but there are other ways to do
this as well outside of the focus of this document.
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 default assemblies and the assembly size is embedded into the firmware of the PM control. 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 EZZONE PM controller and the Originator is the PLC or master on the network. The size of the O to T assembly is fixed at 20 (32-bit) members where the T to O assembly consists of 21 (32-bit) members. All assembly
members are user configurable with the exception of the first T to O member. The first member of the T to
O assembly is called the Device Status, it is unique and cannot be changed. If the module has been properly
configured when viewing this 32-bit member in binary format bits 12 and 16 should always be set to 1 where
all of the other bits should be 0. The 20 members that follow Device Status are user configurable. The Appendix of this User's Guide contains the PM implicit assemblies (See Appendix: CIP Implicit Assembly Structures).

Compact Assembly Class
Along with the standard implicit assembly where each module parameter (member) occupies one 32-bit assembly location there is also a Compact Class assembly. The need for the Compact Class assembly members
became apparent as the number of member instances grew with the EZ-ZONE family of controls. Because
there is a limited number of implicit assembly members (20 input, 20 output), the Compact Class enables the
user to modify the standard assembly offering to their liking while also achieving much better utilization of
each bit within the 32-bit member. As an example, if a standard Implicit Assembly member were configured
to monitor Alarm State 1 the entire 32-bit member would be consumed where just 7 bits out of the 32 will be
used to reflect: Startup (88), None (61), Blocked (12), Alarm Low (8), Alarm High (7) or Error (28) for Alarm
1 only. With Compact Class assembly member 12 (identified in this document as "12 A Alarm Read") in use,
the alarm states of all 4 alarms can be placed in one 32-bit assembly member using just 2 bits for each state.
Bits 0 and 1 would represent Alarm State 1, bits 2 and 3 Alarm State 2, etc... Each pair of 2 bits can represent the following states: 00 = None, 01 = Alarm Low, 10 = Alarm High and 11 = Other. There is a variety of
predefined Compact Class members that can be used (See Appendix: Compact Class Assembly Structure) to
modify the default implicit assemblies.
Note:
As is the case with any available parameter within the PM control the Compact Class members can also be
read or written to individually via an explicit message as well.
Modifying Implicit Assembly Members
To change any given member of either assembly (T to O or O to T) simply write the new class, instance and
attribute (CIA) to the member location of choice. As an example, if it were desired to change the 14th member of the T to O assembly from the default parameter (Cool Power) to the Compact Class 12th member (See
Appendix: Compact Class Assembly Structure) write the value of 0x71, 0x01 and 0x0C (Class, Instance and
Attribute respectively) to 0x77, 0x02 and 0x0D. Once the change is executed, reading this member location
(as was discussed above) will return the Alarm States (1-4) to paired bits 0 through 7 where 00 = None, 01 =
Alarm Low, 10 = Alarm High and 11 = Other.
The CIP communications instance will always be instance 2.
Profibus DP - (Decentralized Peripherals)
This protocol is typically used to operate sensors and actuators via a centralized controller within industrialized production topologies. Data rates up to 12 Mbit/s on twisted pair cables and/or fiber optics are possible.
This protocol is available in three functionally graded version; DP-V0, DP-V1 and DP-V2. It should be noted
that Watlow products utilizing this protocol support DP-V0 and DP-V1 only.
DP-V0 - provides the basic functionality of DP, including cyclic data exchange, station, module and channel
specific diagnostics and four different interrupt types for diagnostics and process interrupts.
Cyclic Data refers to input/output data that is pre-configured to pass from the Profibus-DP Class 1 Master
and the Slave at a known rate. Cyclic data is expected on both the sender and the receiver end of the message.
Note:
To use DP-V0 (cyclic data transfer) first configure and then register the General Station Description (GSD)
file. Watlow provides a software tool allowing for total customization of the data to be read and or written
to. Acquire this software tool (Profibus GSD Editor) via the CD that shipped with the product or, as an alternative, point your browser to: http://www.watlow.com/products/controllers/software.cfm and navigate to
the bottom of the page and click on "Software and Demos" to download the software.
Using the GSD Editor a user can configure up to a maximum of 135 different parameters that can be read or
written to from Zone 1 through 16.
DP-V1 - contains enhancements geared towards process automation, in particular acyclic data communication
for parameter assignment, operation, visualization and interrupt control of intelligent field devices, in conjunction with cyclic user data communication.
Acyclic Data is a message that can be sent and or received at any time where they typically have a lower priority then cyclic messages. This type of messaging is typically used for the purpose of configuration or performing some sort of a diagnostic function.

Software Configuration
Using EZ-ZONE® Configurator Software
To enable a user to configure the PML (Limit) 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 subfolder "EZ-ZONE Configurator"
4.Click on EZ-ZONE Configurator to run.
The first screen that will appear is shown
to the right. If the PC is already physically connected to the EZ-ZONE PML control
click the next button to go on-line.
Note:
When establishing communications from
PC to the EZ-ZONE PML 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 on-line.
After clicking the next button above it is necessary to define the communications port that will be used on
the PC as shown below. Clicking on the drop down will allow the user to select the appropriate communications port. This will be the port assigned to the EIA-485 to USB converter when it was connected to the PC.
The "Advanced" button allows the user to determine how many devices to look for on the network (1 to 17).

After clicking on the "Next" button, the software will scan the network for the zone addresses specified while
showing the progress made (as shown in the graphic below. When complete the software will display all of the
available devices found on the network as shown below
Available Network Devices Displayed
Searching Network for Devices
The PM9L 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 or monitoring;
simply click on the control of choice. After doing so, the screen below will appear. In the screen shot below 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 pa-
rameters within the control. The menu structure as laid out within this software follows:
- Setup - Operations - Factory

Chapter 8 Features
Navigating from one menu to the next is easy and clearly visible. Simply slide the scroll bar up or down to
display the menu and parameter of choice. If there is a need to bring greater focus and clarity to the parameters of interest simply click on the negative symbol next to any of the Menu items. As an example if it
is desired to work within the Operations page click the negative sign next to Setup where the Setup Page
will then collapse. Now click the plus sign next to Operations to find the menu items of choice without viewing unwanted menus and parameters. Once the focus is brought to an individual parameter (single click of
mouse) as is the case for Analog Input 1 in the left column; all that can be setup related to that parameter
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 a thermocouple is selected, RTD Leads
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 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 column.
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 PM Limit 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: Users\"Username"\
My Documents\Watlow\EZ-Zone Configurator\Saved Configurations
The user can save the file to any folder of
choice.

Appendix
As can be seen on the previous page the PM Implicit Assembly defaults (factory settings) to a populated assembly structure. If it is desired to modify any of the given assembly members there are many software tools
available to do so. It is outside of the scope of this document to describe how to use those. What can be found
in this document is the process to build the assembly structure. If viewing this document electronically simply click on the link below to read the section entitled " Modifying Implicit Assembly Members". Otherwise,
turn back to the table of contents to find the above named section.
Compact Class Assembly Structure
On the next four pages the 17 available members of the Compact Class are displayed. As an orientation to the
format as displayed in this document notice that each member begins with header identified as "Assembly"
and below the header you will see the member number along with parameter information contained within.
While looking at these illustrations keep in mind that each member is actually 32-bits in length. To better illustrate this information in this document, the following 6 pages
present these members divided in half where the letter "A" in the
page header and assembly number represents the most significant
16-bits where the letter "B" in the title and assembly number represents the least significant 16-bits of each member. In the event
that these pages are printed out and then mixed up, simply match
up the page headers placing them side by side. As an example,
Compact Class 1 A through 7 A should be paired with Class 1 B
through 7 B, left to right.
For further explanation as to what the Compact Class assembly is, navigate to the section entitled "Compact
Assembly Class"
