WATLOW Series 982 User’s Manual 7.11

Programming, Chapter 7

By this time you should understand the basic concept of the Series

981/982 and be able to get around on your own. Remember that the

Mode key takes you through the menus and the Up/Down keys select

parameters and values.

1. Return to the Program menu by selecting Prog at the OPEr prompt.

Press the Mode key.

2. Press the Mode key again and select 4 when StEP appears. We are

going to change this step type from an End step to a Set Point step.

This is our second ramp. Use Table 7.11 to enter values into the corre-

sponding parameters.

3. Once you have edited your profile, run it again and watch its progress.
