These parameters can be selected to appear in the Operations Page. Select the parameters you want to appear in
the Operations Page in the Programming Page. Press the Advance Key ‰ to enter the Operations Page and to step
through the parameters. For profiling controllers, set
[Prog] to [``no] to access the Operations Page. Press the
Infinity Key ˆ to return to the Home Page at any time.
Note: This chapter only applies to the static set point and profiling versions of the Series SD (SD_C or R - _ _ _ _ - _ _ _ _).
Note: The Operations Page is not accessible when a profile is running.

Note: Parameters appear in the Operations Page only if activated from the programming page. See page 22 for Operations Page defaults.
Note: Some values will be rounded off to fit in the four-character display. Full values can be read with Modbus. All temperature param-
eters through Modbus are in °F, by default.
* Low register numbers contain the two higher bytes; high register numbers contain the two lower bytes of the four-byte integer. Decimal
precision is implied at three decimal places unless otherwise noted.
** Static set point version only (SD_C-_ _ _ _- _ _ _ _ ).
*** Profiling version only (SD_R-_ _ _ _- _ _ _ _ ).
**** This value multiplied by 100 equals the percent power.
