Introduction
The EZ-ZONE® RM Scanner (RMS) is capable of monitoring from 1 to 16 inputs. As is the case
with all of the RM family modules the RMS can be used as a standalone device or it can be
used as part of a larger system of interconnected RM modules. The RMS takes the pain out of
solving your need for high density monitoring requirements as either a stand-alone module or
in applications that require distributed control.
It just got a whole lot easier to solve the thermal requirements of your system. The RMS module is provided in a space-saving, rail-mount package and is highly scalable where you only
pay for what you need. For those applications that require the ability to configure/monitor
the control over a network, Modbus RTU communications is an option. Other communications
protocols are also available (e.g., EtherNet/IP, DeviceNet, Modbus TCP and Profibus DP) when
used in conjunction with an RM Access (RMA) module or when using a Remote User Interface/
Gateway (RUI/GTW).

A Conceptual View of the RMS Module
The flexibility of the RMS software and hardware allows for variation in configurations. Acquiring a better understanding of its 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 scanner in
three parts: inputs, procedures and outputs. Information flows from an input to
a procedure to an output when the scanner is properly configured. An RMS module can carry out several procedures at
Inputs

the same time, e.g., monitoring inputs for
several different alarm situations, monitoring and acting upon digital inputs, and
outputs can be configured to drive devices such as heaters, audible alarms, lights. Each process needs to be thought out carefully and the scanner’s inputs, procedures and outputs set
up properly.

Watlow EZ-ZONE® RMS Module • 6 • Chapter 1 Overview
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. Alternatively, if a failure with the primary sensing device should occur, sensor backup
could be utilized to avoid an unwanted shutdown.
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.
To configure a Digital Input as described above:
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.
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 Transmitter Active Level to execute the desired function.
This configuration is now complete. 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 - 16) is selected (step 5) it will be that instance alone that will be reset.
Note:
Alarms will reset automatically when the condition that caused the alarm goes back to a
non-alarm state if the 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.
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, RTD or thermistor 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. Each analog input must be configured to match the device connected to that input (see: Analog Input Menu, Setup Page).
Each digital input reads whether a device is active or inactive. An RMS module equipped 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 an output with the direction parameter (see: Digital Input/Output Menu, Setup Page).

as either an input or an output. Each pair of terminals must be configured to function as either an input or an output with the direction parameter (see: Digital Input/Output Menu, Setup Page).
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; driving a heater; turning a
light on or off; unlocking a door; or turning on an audible alarm.
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 an RMS
module, an output can be configured to respond to the output of the PID algorithm from another RM module to drive a heater.
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.
Actions
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, set alarms to off, silencing alarms and re-
storing user memory.
A Conceptual View of RM Hardware Configurations
Due to the scalability and flexibility in the RM system a user has several options available in
the way that the hardware can be connected. Listed below are a few examples.
RMS Connected to a Remote User Interface (RUI) and a Personal Computer (PC)
In this configuration the RUI and PC are connected to the RMS module via Watlow's Standard
Bus where both will be able to talk directly to the RMS module.
In the graphic to the right, the PC running EZ-ZONE
Configurator software and or the RUI can be used to configure and then monitor the RMS and other modules connected to it

Note:
If it is intended to use an RUI or a PC using
EZ-ZONE Configurator software it will be necessary to switch the protocol on the RMS to Watlow's
Standard Bus to successfully communicate; follow
the steps below to switch the RMS to the Standard
bus protocol.
1. Disconnect all Modbus devices from the network
2. Push and hold the orange button on the face of
the module for approximately 6 seconds
3. When the LED display (above the orange button)
changes to P, momentarily release the orange
button and then push it again where S will appear (symbol for Standard Bus), release the orange button
4. Push the orange button again for approximately 3 seconds (LED display will become
brighter) to change the Standard Bus address if needed

RMS Module Connected to an Operator Interface Terminal (OIT) through an RMA
In this configuration the RMS can be connected to the OIT through the RMA running any of a
number of available protocols. The RMA and the OIT must be using the same protocol while
the communications from RMA to the RMS module is accomplished over the backplane using
Watlow's Standard Bus protocol. Available protocols in the RMA follow:
1. EtherNet/IP and or Modbus TCP
2. DeviceNet
3. Modbus RTU
4. Profibus DP
Notice that in the example to the right that
there is an optional RUI connected to the RMS
module. An OIT is not generally used to configure a control but is used more for run-time
information. As an alternative for configuration
the RUI could be used to configure and monitor in a remote location.
If using Modbus, one advantage in using an RMA module while also having an RUI and a PC
connected is that the RMS could be set for Standard Bus all of the time while the RMA can simultaneously run Modbus and Standard Bus protocols, no protocol switching required.

Module Orientation
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.
Note:
For correct operation and accuracy, the module must be mounted in a vertical orientation
as shown.
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 the orange button for approximately 2 seconds. The address
will intensify indicating that it can now be
E
changed. Release and repeatedly press to change
D
to the desired unique address.
2. For the scanner module, if equipped with the
Modbus protocol (RMSxxxxxxxxx1xx), pushing
B
A
and holding the orange button for approximately
6 seconds will cause the module to display P for
protocol. Releasing the button and then pushing
it again (within 6 seconds), the display will toggle
between N (Modbus) and S (Standard Bus). Valid addresses for Modbus and 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 Access module is shipped at address J or 17.

Getting Started Quickly
Consider taking the following steps to quickly commission your control:
• Wire and connect the power source to the control
• Wire and connect input and output devices to the control
• Power up the control and navigate to the Setup Page to configure inputs, outputs, adjust
set points, alarms, etc...
The RMS controller has a page and menu structure that is listed below along with a brief description of its purpose. The menu structure can be easily seen and navigated using EZ-ZONE
Configurator software or the Remote User Interface (RUI).
Watlow EZ-ZONE® RMS Module • 10 • Chapter 1 Overview
Note:
EZ-ZONE RMS Default Configuration
The menu navigation as described below applies when the RMS is connected to the RUI
which is optional equipment.
Setup Page
Using the RUI, push and hold the up and
down keys (¿ ¯) for 6 seconds to enter.
(See the Setup Page for further information)
Operations Page
Using the RUI push and hold the up and
down keys (¿ ¯) for 3 seconds to enter.
(See the Operations Page for further information)
Factory Page
Using the RUI push and hold the Infinity
and the green Advance keys (ˆ ‰) for 6
seconds to enter. (See the Factory Page
for further information)
Home Page
When using the RUI, the control is at the
Home Page when initially powered up
where it will display the value of Analog
Input 1 in the upper display and the value
of Analog Input 2 in the lower display.
Note:
The Home Page is visible only when using the RUI.
A user would want to setup their control prior
to operation. As an example, define the input
type, alarm sides (high and or low) or set the
output function.
After setting up the control to reflect your
equipment, the Operations Page would be
used to monitor or change runtime settings.
As an example, the user may want to see the
current status (on or off) of an event in the
Action Menu.
For the most part the Factory Page has no
bearing on the control when running. A user
may want to enable password protection,
view the control part number or perhaps create a custom Home Page.
Pushing the green Advance Key ‰ will cause
the display to show the value of Analog Input
1 in the upper display and Analog Input 2 in
the lower display. With each successive push
of the green advance key the display will
sequentially show the value of all remaining
analog inputs in the upper display and the
lower display will show the corresponding LED
display. (e.g., Ain3 for input 3)
The default RMS loop configuration out of the box is shown below:
• All Analog Input functions are set to thermocouple, type J (to change go to the Setup Page,
Analog Input Menu)
• All Process Value functions are set to off (to change go to the Setup Page, Process Value
Menu)
• All outputs are set to off (to change go to the Setup Page, Output Menu)
Once the scanner has been wired and setup, power up the control. If using an RUI the upper
display will show the value of Analog Input 1 and the lower display will show the value of Analog Input 2

RMS Installation and Removal on a DIN Rail
Modular Backplane Connector
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
To install the backplane follow the steps below:
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)
2. Next, rotate back plane assembly downward to engage the lower edge of the rail. (Note:
Din Rail clipping distance ranges
from 1.366 -1.389 inches. The back
plane assembly will not latch onto
the rail successfully if the rail is out
of dimension).
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 bottom side of the
back plane assembly).
Note:
For easy removal and placement of
modules it is recommended that there be a 76.2 mm (3.00 in) clearance on the top, bottom and front of each module.
Watlow EZ-ZONE® RMS Module • 22 • Chapter 2 Install and Wire
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.
To install backplane connectors follow the steps below:
1. Attach individual modules to the rail separately.
2. Laterally slide the modules together until
they touch.
3. 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.
Module Installation
In the picture to the right notice that the arrow is pointing at the top lip of the module (on
side).
To install modules on the backplane follow the steps below:
1. Slide the lip of the module over the top of the Modular Backplane Connector and then
push down on the rear of the module. The module will then slide over the two posts just
above the green connector (see pictures below).
Watlow EZ-ZONE® RMS Module • 23 • Chapter 2 Install and Wire
Module Removal
To remove a module from the backplane follow the steps below:
1. Find the red tab protruding from the bottom of the module and pull back on it as shown
to the right.
2. Pull back on the red tab, the two
mounting posts will then release the
module.
3. Lift the module up and slide it up; this
will release the module lip from the
backplane.
Backplane Removal from DIN Rail
To remove a modular backplane connector from the DIN rail follow the steps below:
1. Insert a screw driver into the red locking tab just behind the green connector.
2. Apply downward pressure on the tab by lifting the screwdriver upwards..
3. When released, the tab will move downward and the connector can then be lifted up off
of the DIN rail.
