The flexibility of the RM system software and hardware allows for a large range of configurations. Focusing on the RME module, acquiring a better understanding of its overall functionality and capabilities
while at the same time planning out how this module
can be used will deliver maximum effectiveness in
your application.
The RM system at a high level can have a total
of 17 modules installed, one of which can be an Access module and the others (16 maximum) can be any
combination of available RM modules. Each installed
RM module must have a unique Standard Bus address ranging from 1-9, A-F, H (10 -16). The Access
module will be delivered with a default Standard Bus
address of 17 (J). If not using the default zone address the user will need to define each zone address
via the button on the face of each module.
The RME can be considered an accessory RM
module in that by itself it has no PID control loops.
However, used in conjunction with an RM Controller (RMC) or RM High Density (RMH) module the
RME provides increased I/O capabilities. Outputs of
the RME can be used to drive output loads of various
kinds. For instance, an RME module could be placed
in a remote location (up to 200 feet away) from a PID
controller such as an RMC or RMH to drive a heater.
Some of the user selectable ordering options are
listed below:
1. Class 2 or SELV (Saftey Extra Low Voltage) equiv-
alent Power Supplies:
• 90-264 Vac to 24Vdc @ 31 watts
• 90-264 Vac to 24Vdc @ 60 watts
• 90-264 Vac to 24Vdc @ 91 watts
2. RM Expansion Module can provide:
• 1 to 24 Digital Inputs/Outputs (I/O)
• 4 to 12 Form A Mechanical Relays
• 2 to 4 Form A 10A Solid-State Relays
• 4 inputs for external Current Transformers
(CT)
When using this module, either as a stand-alone
module or used in conjunction with any other RM
module it is useful to remember that each process
needs to be thought out carefully and the controller’s
inputs, functions and outputs configured properly.
Note:
Zones can communicate with one another over the
backplane (local and split rail). Once the system is
configured and running changing zone addresses
without careful deliberation may cause disruption in
operation.

What is an Instance?
The RM system can have many I/O points, in some
cases, as described above, I/O can be placed in remote locations. For example, an RME module can
have 24 digital I/O where each would be numbered
from 1 to 24 and each would be considered a unique
instance. They are named Digital I/O 1, 2, 3, etc...
These instance numbers are then used when you
link inputs, functions and outputs within a module
or when linked to other modules. For example, when
configuring an RME output for heat the control loop
instance (1, 2, 3 or 4) and zone (1 to 16) to drive the
output must be defined.
Functions
Functions, in simple terms, use input signals (realworld or internal), to calculate a value and deliver an
output. A function may be as simple as configuring
the function of the digital output, e.g., alarm, heat,
etc..., or defining a set point for an alarm state to
turn on or off.
To set up a function, one of the first things that
must be considered is the function source and instance. For example, if the control is equipped with
Digital Inputs (source) and it was decided to use DI
9 (instance) it can then be associated with an Action
to reset an individual alarm or all alarms. The steps
below, walk through this configuration:
Setup Page (Digital I/O Menu)
1. Navigate to the Setup Page and then to the Digital
I/O menu.
2. Select the desired instance and set the direction to
input voltage or input dry contact.
Setup Page (Action Menu)
3. Navigate to the Setup Page and then the Action
menu.
4. Set the Action Function to Alarm
5. Select which alarm instance will be reset (0 equals
all)
6. Select the Source Function to Digital I/O
7. Select the Source Instance (step 2 above)
8. Select the Source Zone (0 equals the module being
configured).
9. Select the Active Level to execute the desired func-
tion.
When the selected digital input is active the alarm or
all alarms that are latched without a currently existing alarm condition will be reset. If a specific alarm
instance (1 - 8) is selected (step 5 above), it will be
Alarms will reset automatically when the condition
that caused the alarm goes back to a non-alarm state
if the alarm latching prompt is set to non-latching
(Setup Page, Alarm Menu).
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 affect outside
of the controller, an output must be configured to respond to a function.
Some functions have a hardware input for which
the source/s are preset and cannot be changed. As
an example, CT 1 source function comes not surprisingly, from the CT attached to it. Most functions can
accept more than one input and it would not be uncommon to see the output of one function (internal)
serve as an input to another, as would be the case
with a compare function. The source parameters for
the first input to a function are called Source Function A, Source Instance A and Source Zone A and the
second input, Source Function B, Source Instance B
and Source Zone B and so on.
Inputs
The inputs provide the information that any given
programmed function can act upon. This information
may come from an operator pushing a button, or as
part of a more complex function it may represent one
of ten inputs used for the Linearization function.
Each digital input reads whether a device is active
or inactive. An RME module can be equipped with up
to 24 digital inputs, where the RM system can have
many more. Each digital I/O point must be configured to function as an input or an output with the
direction parameter in the digital I/O Menu (Setup
Page).
Another concept that needs to be understood is
the difference between an input tied to a real-world
device such as a CT and one that is tied to an internal function.
RMC module
- The logic block (within the RME module) is configured as an OR function
- The RME output function is tied to the internal output of the logical OR function
When either process alarm is true (analog input value is greater than the alarm high set point, the realworld output connected to the RME will be driven on.

Outputs
Outputs can perform various functions or actions in
response to information provided by a function, such
as a digital output to turn a light on or off, unlocking
a door; or turning on a buzzer.
Assign a function to an output in the Output
Menu or Digital Output Menu of the Setup Page.
Then select which instance of that function will drive
the selected output. For example, you might assign
an output to respond to an internal output of a compare function.
You can assign more than one output to respond
to a single instance of a function, e.g., alarm 2 could
be used to trigger a light connected to output 1 and a
siren connected to digital output 5.
Actions
Based on a given input (Digital I/O, Logic function,
etc..) the Action function can cause other functions to
occur. To name a few, silencing alarms, turn control
loops off and placing alarms in non-alarm state.
Current

Function
In the example above one can see the Current function on the left which is connected to a real-world
input device (CT) where on the far right the internal
output of the Alarm function is tied to the input of
the Output function where a real-world output device
is then driven such as a siren or a flashing light.
With a slight modification of the graphic above the
example below now ties the real-world analog inputs
from an RMC module directly to its PID control. The
RME module is using the same analog input to drive
an alarm function. For the sake of this example the
following is true:
- Within the RME two unique high process alarms
are configured for analog inputs 1 and 2 of the
Due to the scalability and flexibility in the system
components a user has several options available in
the way that the hardware can be connected. Listed
below are a few examples.
RM System Connected to a Remote User Interface
(RUI) and a PC
In this configuration the RUI and PC are connected
to the RM system via Watlow's Standard Bus where
both will be able to talk directly to any interconnected system module.
RM System Connected to an Operator Interface
Terminal (OIT) through an RUI/Gateway
In this configuration the HMI can be running any
of a number of protocols communicating to the RM
system through Watlow's RUI/Gateway. Available

RM System Connected to a Split Rail with OIT
In this configuration both the Inter-module Bus
(backplane communications) and Standard Bus are
connected between rails to allow for remote capabilities. It is recommended that the split rail connection
not exceed 200 feet. In this configuration the OIT
can communicate with all modules (maximum 16
modules any combination with one Access module).
The picture below represents one of six possible RM
modules. All six will have four slots on the face (slot
A, B, D, and E) and one on the bottom (slot C) not
shown. All of these slots are not always used on all
modules. On the face of the module there is a button
(white circle) under the Zone address (5) that when
pushed and held has the following functions:
1.For any module, push and hold for ~ 2 seconds. The
address will intensify indicating that it can now be
changed. Release and repeatedly press to change
to the desired unique address. Valid addresses over
Standard Bus range from 1 -16 (1 - 9, A is 10, B is
11, C is 12, D is 13, E is 14, F is 15, and h is 16).

The picture on the right shows the Modular Backplane
Connector, both front and rear view. The rear view
is bringing in to focus a metal clip. If the DIN rail is
grounded the Modular Backplane Connector and the
module connected to it will be also (recommended).
Installing the Modular Backplane Connector
Step 1
Hook backplane assembly to upper edge of DIN rail,
(see rear view above, backplane hook detail that
mates with upper rail edge is circled)
Step 2
Next, rotate back plane assembly downward to en
gage the lower edge of the rail. (Note: Din Rail clip ping distance ranges from 1.366 -1.389 inches. The
back plane assembly will not latch onto the rail suc cessfully if the rail is out of dimension).
Step 3
For final positioning and locking, the red tab is to
be pushed upward to further engage the bottom
edge of the rail with an over center snap action
latch. (The red locking tab protrudes from the bot tom side of the back plane assembly).
Installing Multiple Modular Backplane Connectors
Multiple modules are easily aligned and latched together. Each module includes matched mating geometry that facilitates accurate and consistent interconnections. The recommended method of multi-module
attachment is to first attach individual modules to
the rail separately and second to laterally slide the
modules together until they touch. (Refer to steps 1&2
above). When the multi-module system is attached and
laterally positioned to the desired placement the locking tab should be engaged to secure the control system
to the rail, (Refer to step 3 above).
Module Installation
In the picture to the right notice that the arrow is
pointing at the top lip of the module (on side). When installing the module simply slide this lip over the top of
the Modular Backplane Connector and then push down
on the rear of the module where it will seat on the two
posts just above the green connector.
To remove a module from the
Modular Backplane Connector
find the red tab protruding from
the bottom of the module and
pull back on it as shown to the
right. While pulling back on the
red tab the two mounting posts
will release the module where the
module can then be lifted up and
out of the Modular Backplane
Connector.
Removal of the Modular Backplane Connector
A module can be removed from
the Modular Backplane Connector
by inserting a screw driver into
the red locking tab just behind
the green connector and applying
downward pressure on the tab by
lifting the screwdriver upwards.
When released, the tab will move
downward and the connector can
then be lifted up off of the DIN
rail.

Components of a RM system can be installed as
stand-alone modules or can be interconnected on
the DIN rail as shown below. When modules are
connected together, power and communications are
shared between modules over the modular backplane interconnection. Therefore, bringing the necessary power and communications wiring to any
one connector in slot C is sufficient. The modular
backplane interconnect comes standard with every
module ordered and is generic in nature, meaning
any of the RM modules shown below on the DIN
rail can use it.
Modular backplane interconnect
Notice in the split rail system diagram that
a single power supply is being used across both
DIN rails. One notable consideration when designing the hardware layout would be the available power supplied and the loading affect of all
of the modules used. Watlow provides three options for power supplies listed below:
With regards to the modular loading affect, maximum power for each is listed below:
1. RMCxxxxxxxxxxxx @ 7 watts
2. RMEx-xxxx-xxxx @ 7 watts
3. RMAx-xxxx-xxxx @ 4 watts
So, in the split rail system diagram, the maximum current draw on the supply would be 38
Watts.
- 2 RMC modules consumes 14W
- 2 RME modules consumes 14W
- 1 RMA module consumes 4W
- 1 Remote User Interface consumes 6W
With this power requirement the second or third
power supply could be used.
Another hardware configuration scenario
that could present itself (graphic not shown)
would be a configuration that requires more than
one supply. Lets make some assumptions per-
taining to the split rail system diagram shown below.
The power supply used is the 91W supply. The top DIN
rail now has the following modules:
- 2 RMC modules consumes 14W
- 1 RMA consumes 4W
- 11 RME modules consumes 77W
As can now be seen, the total power requirement exceeds 91W. In this case, another power supply would
be required. To incorporate another supply in this system simply disconnect pins 99 and 98 on the remote
DIN rail and connect another appropriately sized power supply to those same pins.
When using a split rail configuration ensure that
the interconnections for the Inter-module Bus and
Standard Bus do not exceed 200 feet. Standard Bus
and the Inter-module Buses are different protocols
and both are required for split rail configurations.
Without having both connected communications between modules would not be possible.

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 and Factory) and their associated
menus have identical headers defined below:
Display
When the RME module is used in conjunction with
the RUI (optional equipment) 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:
Note:
The communications protocols and associated addressing mentioned below and found in the menus are
available only when another module equipped with
the protocol is used in conjunction with the RME. The
RME module by itself has Watlow's Standard Bus
only.

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 prop-
er operation, use User Settings Save [USr;S] (Setup
Page, Global Menu) to save the settings into either of
two files in a special section of memory.

Note:
Starting with firmware release 6, there is only one

If the settings in the controller are altered and you
want to return the controller to the saved values, use
User Settings Restore [USr;r] (Setup Page, Global
Menu) to recall the previously saved settings.
A digital input or the Function Key can also be
configured to restore parameters.
CAUTION:
If a Digital Input or Function Key is programmed for
User Setting Restore, the operator may select Factory Restore and the Digital Input or Function Key
may no longer be programmed for User Setting Restore.
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.
Inputs
Ten Point Linearization
The linearization function allows a user to re-linearize a value read from an analog source. The function
selections are Off, Interpolated and Stepped. When
set to Off the output will match the Source A value
plus offset. There are 10 data points used to compensate for differences between the source value read
(input point) and the desired value (output point).
Multiple data points enable compensation for nonlinear differences between the sensor readings and
target process values over the thermal or process system operating range. Sensor reading differences can
be caused by sensor placement, tolerances, an inaccurate sensor or lead resistance.
The user specifies the unit of measurement and
then each data point by entering an input point value
and a corresponding output point value. Each data
point must be incrementally higher than the previous
point. The linearization function will interpolate data
points linearly in between specified data points.
Time
Outputs
Variable Time Base
Variable time base is the preferred method for controlling a resistive load, providing a very short time
base for longer heater life. Unlike phase-angle firing,
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.
Select the AC Line Frequency [AC;LF] (Setup Page,
Global Menu), 50 or 60 Hz.

Retransmitting a Process Value or Set Point
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 milliamperes.
Typically, applications might use 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 to 3, 7 to 9, 13 to 15 and 19 to 21 can be
ordered as process outputs. Assign an analog source
to Output Function to accomplish retransmit of a
process or set point value.

Motorized Valve Control
A motorized valve is used is to regulate the flow of
fluid which in turn impacts the loop process value. A
valve is opened or closed by closing contacts to drive
the value in the intended direction. This feature is
configured by selecting Motorized Valve as the function in the Setup Page, Special Output Function
menu. Source Function A is selected for either Heat
or Cool Power then entering the Valve Travel Time
and Deadband.
Lastly, program the outputs which will open and
close the valve. The algorithm will calculate Dead
Time which is the minimum on time that the valve
will travel once it is turned on in either the closed or
open direction. Dead Time = Valve Dead Band / 100
* Valve Travel Time.
Note:
The active set point is not retransmitted, only the
user requested closed loop set point which may not be
the closed loop set point in control. Retransmitting a
profiling closed loop set point is not allowed.

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 alarm type [`A;ty] via the 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.
The alarm low set point defines the temperature that
will trigger a low side alarm. For deviation alarms,
a negative set point represents a value below closed
loop set point. A positive set point represents a value
above closed loop set point. View or change alarm set
points with Alarm Low [`A;Lo] and Alarm High Set
Points [`A;hi] (Operations Page, Alarm Menu).
Alarm Hysteresis
An alarm state is triggered when the process value
reaches the alarm high or alarm low set point. Alarm
Hysteresis defines how far the process must return
into the normal operating range before the alarm can
be cleared.
Alarm Hysteresis is a zone inside each alarm set
point. This zone is defined by adding the hysteresis
value to the alarm low set point or subtracting the
hysteresis value from the alarm high set point. View

Alarm Latching
A latched alarm will remain active after the alarm
condition has passed. It can only be deactivated by
the user and only when the alarm condition no longer
exists.
If using an RUI an active message, such as an
alarm message, will cause the display to toggle between the normal settings and the active message in
the upper display and [Attn] in the lower display. To
clear a latched alarm:
1. Push the Advance Key ‰ to display [ignr] in the
upper display and the message source in the lower
displ ay.
2. Use the Up ¿ or Down ¯ keys to scroll through
possible responses, such as Clear [`CLr] or Silence
[`SiL].
3. Push the Advance ‰ or Infinity ˆ key to execute
the action.
Without an RUI, a latched alarm can be reset by
cycling power to the module or configuring an Action function within the control to perform a reset.
Do this by setting the Action Function to alarm and
trigger the Action to occur through Source Function
A.
An alarm that is not latched (self-clearing) will deactivate automatically when the alarm condition has
passed. Turn Alarm Latching [`A;LA] on or off via
the Setup Page, Alarm Menu.

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 RME module 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.
Turn Alarm Blocking [`A;bL] on or off via the
Setup Page, Alarm Menu.
Programming the EZ Key/s
If using an RUI the EZ Key can be configured either
in the Setup Menu or with EZ-ZONE configurator
software, using a personal computer.
The following examples show how to program the
EZ Key to start and stop a profile.
1. To go to the Setup Page from the Home Page,
press both the Up ¿ and Down ¯ keys for six seconds. [``Ai] will appear in the upper display and
[`Set] will appear in the lower display.
2. Press the Up Key ¿ until [`Fun] appears in the
upper display and [`SEt] will appear in the lower
displ ay.
3. Press the Advance Key ‰ until Digital Input Level
[`leu] appears in the lower display. Use an arrow key to specify the state of the key (high or low)
when the controller is powered up. Functions will
toggle with each press of the EZ Key, such as Profile Start/Stop.
4. Press the Advance Key ‰. The lower display will
show Digital Function [``Fn]. Press the Up ¿ or
Down ¯ key to scroll through the functions that
can be assigned to the EZ Key
When Profile Start/Stop [P;StS] appears in the
upper display and [``Fn] appears in the lower
display, press the Advance Key ‰ once to select
that function and move to the Function Instance
[``Fi] parameter.
5. Press the Up ¿ or Down ¯ key to scroll to the
profile that you want the EZ Key to control.
6. The instance tells the controller which of the
numbered functions should be acted upon. For
profiles, there are 25 instances. Press the Infinity Key ˆ once to return to the submenu, twice to
return to the main menu or three times to return
to the Home Page.
Using Lockout to Hide Pages and Menus
If unintentional changes to parameter settings might
raise safety concerns or lead to downtime, your can
use the lockout feature to make them more secure.
These settings will affect any access using Standard
Bus, including the RUI. This does not affect field protocol access.
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
level 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
off the Password security feature. (default: off)
• Read Lockout Security [rLoC] determines which
pages can be accessed. The user can access the se lected level and all lower levels. (default: 5)
• Set Lockout Security [SLoC] determines which
parameters within accessible pages can be written
to. The user can write to the selected level and all
lower levels. (default: 5)
The table that follows represents the various levels
of lockout for the Set Lockout Security prompt and
the Read Lockout Security prompt. The Set Lockout
has 6 levels (0-5) of security where the Read Lockout
has 5 (1-5). Therefore, level "0" applies to Set Lockout
only. "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.

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. If Set Lockout Security
[SLoC] is set to 2 or higher and the Read Lockout Security [rLoC] is set to 2, the Home Pages
can be accessed, and all writable parameters can
be written to. Pages with security levels greater
than 2 will be locked out (inaccessible).
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
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 lock all other pages and menus.
In the Factory Page, Lockout Menu, set Read
Lockout 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.
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
Lockout 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.
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
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:

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

the only Pages that a User without a password has
visibility to are defined in the Locked Access Level

Software Configuration
Using EZ-ZONE® Configurator Software
To enable a user to configure the RME module 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.
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"

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 an input, output parameters do not apply and are
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 all Digital

where a copy from to copy to dialog box will appear
allowing for quick duplication of all settings. Notice
In the screen shot above notice that the device
part number is clearly displayed at the top of the
page (green 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 RME.
The menu structure as laid out within this software
follows:
- Setup
- Operations
- Factory
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.
As an alternative, clicking on the negative symbol
next to Setup will collapse the Setup Menu. The Operations Menu will appear next and perhaps deliver
more clarity for the area of focus by not displaying
unwanted menus and parameters. Once the focus
is brought to an individual parameter (single click
of mouse) as is the case for Digital I/O 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 Digital I/O 1 is configured
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 RME module 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

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 sav-
ing 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:
The user can save the file to any folder of choice.

Each of the next several pages graphically shows each of
the RME function blocks. Note that as you view each you
will find text that is black and text that appears gray. The
gray text represents inputs that are not currently available
based on the functions defined use (red text). For instance,
when the defined use of the Alarm function is set to Off,
all parameters will appear gray. Ranges specified are in
units or degrees F, if expressed in degrees C, the range will
be smaller.
Action Function
The Action Function will cause the action selected
to occur when Source Function A = ON and Active
Level = High. The active level specifies when the action occurs. A digital value that is high causes the
action function when Active Level = High. A digital
value that is low causes the action function when Active Level = Low. Based on a given input (Digital I/O,
Event output, Logic function, etc), the Action function can cause other functions to occur. To name a
few, starting and stopping a profile, silencing alarms,
turn control loops off and placing alarms in nonalarm state.
Note:
Note: Action Function selection is module type and
part number dependant.

Function counts up or down from Load Value and produces
Output Value = On when Count = Target Value.
Note:
Count value clears on power loss.
Load Value restored on power up.
Counter Operation:
Whenever a prescribed clock transition occurs without an error on source B the count will be equal to
the Load Value.
If Function is an Up Counter:
Whenever a prescribed clock transition occurs without an error on Source A the count will increment by
+1. If the count is equal to 9,999 when the transition
occurs count will be 1 after transition.
If Function is a Down Counter:
Whenever a prescribed clock transition occurs without an error on Source A the count will decrement by
-1. If the count is equal to 0 when the transition occurs the count will be 9,999 after transition.
