Watlow EZ-ZONE RM Limit Module Rev C - Manual (Page 11)

Watlow EZ-ZONE ® RML Module • 8 • Chapter 1 Overview
Getting Started Quickly
Consider taking the following steps to quickly com-
mission 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, alarms, etc...
• Once the control is setup, navigate to the Opera-
tions Page to set limit and alarm set points.
The default RML loop configuration out of the box is
shown below:
• Analog Input functions are set to thermocouple,
type J (to change go to the Setup Page)
• Limit sides set to both, high and low (to change
go to the Setup Page)
• Output 8 set to module limit (to change go to the
Setup Page)
• Limit low set point set to 0°F (to change go to the
Operations Page)
• Limit high set point set to 0°F (to change go to
the Operations Page)
• Limit is deenergized, also referred to as a tripped
state
Once the control has been wired and setup, power
up the control and change the appropriate limit set
points (high and or low) to the desired value (on the
RUI push the up ¿ and or down ¯ arrow key). Once
the set point is set to the desired level, reset the limit
by using one of the four methods described below:
1 - Use a digital input, function key or a variable
to reset the limit
2 - Using an RUI, push the green Advance Key ‰
and then the Infinity Key ˆ
3 - Using Modbus RTU send the enumerated value
of zero (0) to register 1490, loop 1 (see the Op-
erations Page, Limit Menu)
4 - Cycle power on the control

Note:
Output 8 will default as a module limit. As a mod-
ule limit, the LED will be illuminated when one or
more limit loops is in a tripped (deenergized) state.
When the module is in a safe state the output LED
will be off.
The RML 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 soft-
ware or the Remote User Interface (RUI).
Note:
The menu navigation as described below applies
when the RML is connected to the RUI which is op-
tional equipment.
Setup Page
Using the RUI, push
and hold the up and
down keys (¿ ¯) for 6
seconds to enter. (See
the Setup Page for fur-
ther information)
A user would want to
setup their control prior
to operation. As an ex-
ample, define the limit
sides (high and or low),
change the input type,
or set the output func-
tion.
Operations Page
Using the RUI push and
hold the up and down
keys (¿ ¯) for 3 seconds
to enter. (See the Op-
erations Page for further
information)
After setting up the
control to reflect your
equipment, the Op-
erations Page would
be used to monitor or
change runtime settings.
As an example, the user
may want to change the
limit high/low set point
or perhaps change an
alarm set point.
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 infor-
mation)
For the most part the
Factory Page has no
bearing on the con-
trol when running. A
user may want to en-
able password protec-
tion, view the control
part number or perhaps
create a custom Home
Page.
Home Page
When using the RUI the
control is at the Home
Page when initially pow-
ered up.
Note:
The Home Page is vis-
ible only when using
the RUI.
Pushing the green Ad-
vance Key ‰ and then
the Infinity Key ˆ will
reset a limit if tripped (if
trip condition no longer
exists); or, by pushing
the green Advance Key
‰ the limit high and or
low set points could be
displayed and changed
using the up and down
keys (¿ ¯).
