BAND DEVIATION

When deviation is selected from the setup menu, a value is entered for the amount of deviation
required. This value represents the number of counts at which the relay will be energized above
and below the setpoint. For example, if the setpoint is set to 10,000 and a deviation value of
200 was entered, the relay will activate below 9800 and above 10,200.

18.4

HYSTERESIS

When hysteresis is selected from the setup menu, a value is entered for the amount of
hysteresis required. This value represents the number of counts at which the relay will be
energized above and deenergized below the setpoint. For example, if the setpoint is set to
10,000 and a hysteresis value of 200 was entered, the relay will activate at 10200 and
deactivate at 9800.
