Low alarm level for input channel 0. When the input value for this channel is less than the low
value, the corresponding low alarm bit is set in the BTR.
High alarm level for input channel 0. When the input value for this channel is greater than the
high value, the corresponding high alarm bit is set in the BTR.
Alarm deadband for input channel 0. This field creates a hysteresis effect on the low and high
alarms. For an alarm condition to be removed, the input signal must go above the low alarm
limit or below the high alarm limit by an amount equal to the specified deadband. Alarm
deadband values must be less than or equal to one half the difference of the high and low
alarm values.
Low alarm level for input channel 1. When the input value for this channel is less than the low
value, the corresponding low alarm bit is set in the BTR.
High alarm level for input channel 1. When the input value for this channel is greater than the
high value, the corresponding high alarm bit is set in the BTR.
Alarm deadband for input channel 1. This field creates a hysteresis effect on the low and high
alarms. For an alarm condition to be removed, the input signal must go above the low alarm
limit or below the high alarm limit by an amount equal to the specified deadband. Alarm
deadband values must be less than or equal to one half the difference of the high and low
alarm values.
Low alarm level for input channel 2. When the input value for this channel is less than the low
value, the corresponding low alarm bit is set in the BTR.
High alarm level for input channel 2. When the input value for this channel is greater than the
high value, the corresponding high alarm bit is set in the BTR.
Alarm deadband for input channel 2. This field creates a hysteresis effect on the low and high
alarms. For an alarm condition to be removed, the input signal must go above the low alarm
limit or below the high alarm limit by an amount equal to the specified deadband. Alarm
deadband values must be less than or equal to one half the difference of the high and low
alarm values.
Low alarm level for input channel 3. When the input value for this channel is less than the low
value, the corresponding low alarm bit is set in the BTR.
