ANALOG THRESHOLD 1
DROP OUT RATIO: 5
Range: 2 to 20 in steps of 1
Enter the drop out ratio for this analog input monitoring element. The value
programmed here represents the value at which the element will effectively
drop out. This is a percentage of the pickup value. If 5000
µ
A has been pro-
grammed as the pickup level and this setpoint is programmed for a drop out
ratio of
10 , then the drop out current will be 4500
µ
A.
