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 Opera-
tions 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 au-
tomatically changed in the Home Page.
The Attention
[Attn]
parameter appears only if there is an active message. An example of an active mes-
sage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 Limit Low Set Point [ll;51] prompt will ap-
pear 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 Limit High Set
Point [lh;51] will appear below and the current high set point will be displayed above. Again, to change sim-
plypushtheUpandDownarrowkeys.
