Alarm Monitor Description Explanation/Corrective Action

configured.

indicated by “tagname” is not valid and must be corrected to clear the alarm.
Check and correct setup values of output 2, PB, TI and output 1. If output 2
is required for cooling control, the control should use PID mode (PB > 0, TI
> 0 ) and output 1 should use reverse mode (heat action), otherwise, don't
use output 2 for cooling control.
