Monitoring of the analog input can be performed by two separate functions, each operating at different thresholds of analog
input current and each having a selection to trip, alarm, or control. Control allows the element to signal its own output
relay(s). For user flexibility, independent user names can also be programmed for each Analog Threshold.
Note that connected analog input will still be read and displayed in A2 METERING ÖØ A/I if both ANALOG THRESHLD 1 FUNC-
TION and ANALOG THRESHLD 2 FUNCTION are set to “Disabled”. The “Blk Thrsh 1" value applies to the ANALOG THRESHLD 2
FUNCTION setpoint only.
The value programmed in the
ANALOG THRESHLD 1 DROP OUT RATIO setpoint represents the value at which the element will
effectively drop out as a percentage of the pickup value. If the pickup level is 5000 μA and this setpoint is programmed for
a drop out ratio of “10”, then the drop out current will be 4500 μA. The drop out ratio is defined as follows:
(EQ 5.21)
The ANALOG THRESHLD 1 PICKUP TYPE setpoint determines if pickup will occur when the analog input is over or under the
programmed threshold. When set to “Over”, the Drop Out value is calculated shown in the equation above.
