Watlow Series SD ■ 40 ■ Chapter 7 Programming
Programming Page Example
An oven manufacturer wants users of their ovens to have easy access to the Series SD PID parameters. They also
want to limit access to other parameters they do not want them to change. This can be achieved by customizing the
Operations Page. The Programming Page configuration determines which parameters appear on the Operations
Page. The static set point version (SD_C-_ _ _ _- _ _ _ _.) has 20 Programming Page locations, P1 to P20. The profil-
ing version (SD_R-_ _ _ _- _ _ _ _.) has 23 Programming Page locations, P1 to P23.
The oven manufacturer wants only these parameters to appear on the Operations Page:
• Heat Output Power
• Fahrenheit/Celsius
• Autotune
• Modbus Device Address
To go to the Programming Page, press the Advance ‰ and Infinity ˆ keys for six seconds from the Home Page.
{Prog} will appear in the upper display and {page} in the lower display.
• Press the Advance Key ‰ to move through the parameter prompts.
• Press the Up ¿ or Down ¯ keys to change the parameter value.
• Press the Infinity Key ˆ at any time to return to the Home Page.
On the Programming Page, select the following settings:
[Po;ht] [~C-F] [~Aut] [Addr] [none] [none]
[~~P1] [~~P2] [~~P3] [~~P4] [~~P5] thru [~P20]
To access the Operation Page parameters, press the Infinity ˆ key to return to the Home Page. Press the Ad-
vance ‰ key to see the Operation Page parameters. Only the parameters selected on the Programming Page ap-
pear on the Operations Page.
