delay.
You can also enter a hysteresis value to prevent the alarm monitor from
unwanted rapid “switching”, when the input signal is around the limit or
criteria.
.
For example: A MajorHigh Limit is set to 57.00VDC, with a Hysteresis of
0.10VDC and a Time delay of 5 seconds.
An input signal of 57.08VDC lasting 3 seconds will not cause the alarm
monitor to raise an alarm.
The alarm will only be generated when the input signal is over 57.00VDC for a
longer period of time than 5 seconds (the Time delay).
The alarm will only be switched off when the input signal is lower than
56.90VDC (the hysteresis).
 Monitored Limits and Events
Analogue and numeric alarm monitors compare the measured input with from
one to four user-defined values or limits; two above normal value (Major High
and Minor High) and two below normal value (Minor Low and Major Low).
The type and number of internal actions (events) are usually defined from
factory.
Logical alarm monitors only compare the measured input signal with a logical
state (normally open or closed). The user can define the alarm group that the
monitor will activate when the input signal is not in the normal state.
 Alarm output groups
For each value or limit, you can select which alarm output group (AOG) the
alarm monitor will activate, in the event the measured input reaches the specific
limit
 Measured Average Value
The alarm monitor stores all input signal measurements and performs average
calculations every minute. Then, the monitor continuously displays the input
signal average value, and the period of time the input signal has been
measured. You can restart the monitor’s average calculations.
 Measured Peak Value
The alarm monitor stores all input signal measurements. Then, the monitor
continuously displays the input signal peak value, since the measurements
started. You can restart the monitor’s peak value measurements.
In addition, you can configure the alarm monitors with a description of the alarm monitor
and other configuration parameters.
