Chapter 4: Home Page

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 Page is shown on the follow-
ing page. When a parameter normally located in the
Setup Page or Operations 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 param-
eter in its original page it is automatically changed
in the Home Page.
The Attention
[Attn]
parameter appears only if
there is an active message. An example of an active
message could be a Current Error [C;Er1], or it could
be for information only like Autotune [tUN1] taking
place.
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 ¿ 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 Manu-
al, the Process Value is in the upper display and the
output 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, [----] is in the
upper display 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 top and
Parameter [`par] in the bottom. Using the Up ¿ or
Down ¯ arrow keys will allow for a customized se-
lection 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
Diagnostic Menu [diag] (Factory Page). The listing
in the table that follows is what one may typically
find in the Home Page as defaults based on control-
ler part numbers. It is important to note that some
of the prompts shown may not appear simply because
the feature is not being used or is turned off. As an
example, the prompt shown in position 7 (loop 1) and
position 12 (loop 2) [`C;pr] will not appear unless
the Cool algorithm [`C;ag ] is turned on in the Setup
Page under the Loop menu.
If the ninth digit of the part number is C, J, L or M
(PM _ _ _ _ _ - _ [C, J, L, M] _ _ _ _ _) the Display
Pairs [d;prs] prompt will default to 2; otherwise, it
will be equal to one.
As stated above, the user can define pairs of
prompts to appear on the display every time the Ad-
vance
key
is pushed. The first pair will always
be as defined in the Custom Menu and as stated
will default (factory settings) to the Active Process
Value loop 1 [aC;pu], and the Active Set Point loop 1
[aC;sp]. If two channels are present the first 2 pairs
will be the same in that the first pair will represent
channel 1 Active Process Value and Active Set Point
and the second being the same for channel 2. If an-
other pair is created where the Display Pairs [d;prs]
prompt is equal to 3 using the default prompts, when
the Advance key
is pushed two times from the
Home Page the upper display will reflect the current
control mode and the bottom display would show the
output power. When configuring the Custom Menu
to your liking it should be noted that if 2 change-
able (writable) prompts are displayed in a Pair, i.e.,
Control Mode on top and Idle Set Point on the bot-
tom, only the lower display (Idle Set Point) can be
changed.
The display can be configured to scroll by go-
ing to the Factory Page under the Diagnostic Menu
and changing 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.
