*Cycle times are in either 1 second or 1/3 second increments, depending upon the RLY TYPE configuration in the
Output Algorithm Set Up group.

If units of percent proportional band (PB) are selected under the Control Set Up prompt, function
prompt PBorGAIN, then the displayed values are in %PB, but the lower display will still show Gain.
