4Chapter 4: Home Page

Default Home Page Parameters

The Home Page is a customized list of as many as 20 parameters that can be configured and changed in the Custom Menu [CUSt] (Factory Page). The default list of nine parameters below includes the Active Process Value (value in upper display) and Active Set Point (value in lower display). The Attention [Attn] parameter appears only if there is an active message. An active message could be a reported error, for ex- ample, [C;Er1] (Current Error), or it could be for information only, for example, [tUN1] (Autotuning).

Use the Advance Key ‰ to step through the other parameters. 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 read-write pa- rameters, 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 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 ¿ and Down ¯ keys, when a profile is not running.

If the set point is displayed and the % indicator is lit, the controller is in open-loop (manual) mode.

Note: Avoid continuous writes within loops. Excessive writes to EEPROM will cause premature EEPROM failure. The EEPROM is rated for 1,000,000 writes.
