Watlow EZ-ZONE ® RUI/Gateway • 15 • Chapter 3 Keys and Displays
Default Home Pages
Watlow’s patented user-defined menu system im-
proves operational efficiency. The user-defined Home
Page provides you with a shortcut to monitor or
change the parameter values that you use most of-
ten. The default Home Pages for the EZ-ZONE PM
Express, ST, Panel Mount (PM) and Rail Mount (RM)
controllers are shown on the following pages. When a
parameter normally located in the Setup Page or Op-
erations Page is placed in the Home Page, it is acces-
sible 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.
Use the Advance Key ‰ to step through the Home
Page parameters. When not in pairs the parameter
prompt will appear in the lower display, and the pa-
rameter value will appear in the upper display. You
can use the Up ¿ and Down ¯ keys to change the
value of writable parameters, just as you would in
any other menu.
If Control Mode is set to Auto, the Process Value
is in the upper display and the Closed Loop Set Point
(read-write) is in the lower display.
If a profile is running, the process value is in the
upper display and the Target Set Point (read only) is
in the lower display. If Control Mode is set to Manual,
the Process Value is in the upper display and the out-
put power level (read-write) is in the lower display.
If Control Mode is set to Off, the Process Value is
in the upper display and [`oFF] (read only) is in the
lower display.
If a sensor failure has occurred, the upper display
will show four dashes [----] and the output power
level (read-write) is in the lower display.
Changing the Set Point
You can change the set point by using the Up ¿ or
Down ¯ keys when a profile is not running.
Modifying the Home Page
To modify the Home Page proceed to the Factory
Menu by pushing and holding 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]. Once there push the
Advance ‰ key where the lower display will show
[Cust] and the upper display will show [1]. Again,
push the Advance ‰ button where the prompt for the
Process Value [aC;pu] will be displayed on the top and
Parameter [`par] on the bottom. Using the Up ¿ or
Down ¯ arrow keys will allow for a customized selec-
tion of choice. There are twenty positions available
that can be customized.
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 found in the
Global Menu [glbl] (Setup Page).
As stated above, the user can define pairs of
prompts to appear on the display every time the Ad-
vance ‰ key is pushed. For each controller the first
pair will always be as defined in the Custom Menu
and as stated will default (factory settings) to the Ac-
tive Process Value loop 1 [aC;pu], and the Active Set
Point loop 1 [aC;sp]. For the Limit, it would be the
Active Process Value [aC;pu],and Limit Status, either
Safe [safe] or Fail [fail]. When configuring the
Custom Menu to your liking it should be noted that
if 2 changeable (writable) prompts are displayed in a
Pair, i.e., Control Mode on top and Idle Set Point on
the bottom, only the lower display (Idle Set Point) can
be changed.
On some controllers the display can also be con-
figured to scroll automatically through multiple chan-
nels and then through all configured display pairs.
Go to the Setup Page under the Global Menu and
change the Display Time [`d;ti] prompt to something
greater than 0. If set to 2, the display will scroll every
2 seconds from channel 1 to 2 (if present) and then
through all of the custom pairs that are configured.
