Item 4 Selects HIGH or LOW alarm conditions. A high alarm is active when the
variable exceeds the limit. A low alarm is active when the variable is below
the limit. An algebraic comparison is used, thus a speed of “–60” is
below
a
limit of “–50”.
Item 5 This is the numerical value at which the alarm is triggered. This number can
also be changed in the
1.0 SET ALARMS
menu.
Item 6 Sets the dead-band associated with the alarm setting. The dead-band value
prevents chattering. The alarm turns on at the limit specified and remains on
until the line variable is less than LIMIT – DEADBAND for high alarms, or
greater than LIMIT + DEADBAND for low alarms.
