13.5.3 ANALOG THRESHOLD
Monitoring of the analog input can be performed by two separate functions, each operating at different thresh-
olds 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
.
All of the following setpoints are repeated for
ANALOG THRESHOLD 2
.
ANALOG INPUT MAXIMUM
VALUE: 20000
µ
A
Range: 0 to 65535 in steps of 1
Enter the value of the quantity measured which corresponds to the maximum
output value of the transducer. For example, if a temperature transducer which
outputs 4 to 20 mA for temperatures 0 to 250 °C has been connected to the
analog input, then enter
250 for this setpoint. The relay will therefore interpret
20 mA as representing 250 °C. Intermediate values between the minimum and
maximum will be scaled linearly.

The
ANALOG THRESHOLD 1
setpoints path is:
\ SETPOINTS \ S6 MONITORING \ ANALOG INPUT \ ANALOG THRESHOLD 1
A/I THRESHLD 1 NAME:
Analog Threshld 1
Range: any combination of 18 alphanumeric characters.
Enter the name of threshold 1. See Section 8.10: USER TEXT MESSAGES on
page 8–11 for a description of entering text from the front panel. This name will
be displayed instead of
Analog Threshld 1 (the factory default) in the remaining
setpoints in
SETPOINTS \ S6 MONITORING \ ANALOG INPUT \ ANALOG THRESHOLD 1
.
This user name will also appear when an associated trip or alarm is generated
as well as being stored in the event recorder if programmed to do so.
ANALOG THRESHOLD 1
FUNCTION: Disabled
Range: Disabled, Trip, Alarm, Latched Alarm, Control, Blk Thrsh 1
†
Select the required function. Note that a connected analog input will still be
read and displayed in
A2 METERING \ ANALOG INPUT
if both the
ANALOG THRESH-
OLD 1
and
ANALOG THRESHOLD 2
functions are set to Disabled .
† The
Blk Thrsh 1 value applies to the
ANALOG THRESHOLD 2 FUNCTION
set-
point only.
ANALOG THRESHOLD 1
RELAYS (3-7): -----
Range: Any Combination of the 3-7 AUXILIARY Relays
Select the output relays required.
ANALOG THRESHOLD 1
PICKUP: 100
µ
A
Range: 0 to 65535 in steps of 1 unit
Enter the pickup value for this analog input monitoring element. The units dis-
played will be those entered in the analog input setup. For example, if a tem-
perature transducer is connected to the analog input, and an alarm is required
when the temperature exceeds 90°C, enter
90 for this setpoint. When the
measured value of analog input exceeds this setting for a period longer than
the delay setting, an output will occur and the user selected relays will signal
an output.
