Above Return Hysteresis = 105%; Below Return Hysteresis = 95%
(Stay out of Limit until below 126V)(Stay out of Limit until above 114V)
NOTES:
• The Primary fields are display only. They show what the set point and return
Hysteresis value are for each limit.
• If the Above Return Hysteresis is greater than the Above Set Point, the Above Limit is Disabled;
if the Below Return Hysteresis is less than the Below Set Point, the Below Limit is Disabled. You
may want to use this feature to disable either the Above Limit or Below Limit condition for a
reading.
• If you are entering negative limits, be aware that the negative value affects the way the above
and below limits function, since negative numbers are processed as signed values.
