Table 3-11 Setpoint Parameters
Notes:
1.
When Reversal is set as the Setpoint Parameter, the Setpoint Type should be set to 1 (i.e., Over Setpoint). The Setpoint
Type=2 (i.e., Under Setpoint) is invalid.
2.
When Reversal is set as the Setpoint Parameter (with Setpoint Type=1), the Over Limit should be set as 0 and Under Limit
should be as 1. The logic diagram for the Phase Reversal setpoint is illustrated in the following figure:
