6.5Configuring and Invoking the Single-Step Ramp Function

The CN8-SW system provides a method to configure the single-step ramp time. The software also provides a means to invoke this single-step Ramp to Setpoint function in those Omega controllers that can use the function at times other than at startup.

To configure the timer for the single step Ramp to Setpoint function:

1.While logged in as MULTI (or another user with View/Change Parameter privileges), select the controller by clicking on it in the main graphic display.

2.To see the present values of all parameters stored in the controllerÕs non-volatile memory, select Controller Parameters. The parameter window for that controller will open. By default, the Input ÒtabÓ will be on top.

3.Click on the Recipe tab. The existing recipe-related parameter values will be displayed.

4.To enable Single-Step Ramp, click on the white dot (Òradio buttonÓ) next to it. A black dot in the circle indicates that the function has been selected. The gray number in the Ramp Time entry box will become black, indicating that the number can be changed.

5.Enter the ramp time (in minutes) to be used to achieve the current setpoint when either of two conditions occur: power to the controller is cycled or the CN8-SW system is used to gradually ramp to the current setpoint.

6.Click on OK. The value will be sent to the controller and the window will close.
