System Value Sources
Parameter
Setting
SA Num
Type the number (from the
Smart Alarm States
table) of the
Smart Alarm
for
which this source is an input.
Status
Set to
Enabled
.
System Value
Set to the required value (
Bus Voltage, Rectifier Current, Load Current, Battery
Current, Battery Temperature, Load Power, System Power, Ah Discharged, Number
Of Rectifiers Failed, Number Of Rectifiers Comms Lost, AC Voltage, DC Input
Voltage, Rectifier Input Voltage, Battery Time Remaining, Battery Health, Alternative
Source Current, Solar Current, Solar Power, Generator Power, Highest Rectifier
Heatsink Temperature, Fuel Level, Generator Backup Time, Fuel Remaining Time,
Smart Analog, Energy Meter, Power Meter, Current Meter, Voltage Meter
).
System Value
Index
Where the System Value is in a table of values, the position in this table.
This
applies to Smart Analog, Energy Meter, Power Meter, Current Meter, and Voltage
Meter items.
Threshold Type
Set to either:
High
- the System Value Source will be true when the System Value goes
above the Threshold.
Low
– the System Value Source will be true when the System Value goes
below the Threshold.
Threshold
The System Value Source will be true when the System Value goes above or
below (depending on the Threshold Type) this value.
Hysteresis
Determines when an active
System Value Source
will become false:
If
Threshold Type
is set to
Low
the
System Value Source
will become false when
the
System Value
goes above
Threshold
+
Hysteresis
.
If
Threshold Type
is set to
High
the
System Value Source
will become false when
the
System Value
goes below
Threshold
-
Hysteresis
.
Invert
The source is inverted before it is used to trigger the
Smart Alarm.
The
Smart
Alarm
will be triggered when the source becomes inactive.
Invert
The source is inverted before it is used to trigger the
Smart Alarm.
The
Smart
Alarm
will be triggered when the source becomes inactive.
Active Count
Sets the number of transitions before the Smart Alarm becomes active. E.g. If
this is set to 2, then two inactive to active transitions are required before the
Smart Alarm becomes active.
Trigger
Specify how the source is used to trigger the
Smart Alarm.
Level –
triggered as long as the source is active.
Edge Set
– triggered when the source becomes active
.
Edge Reset
– triggered when the source becomes inactive
Edge Latch –
triggered when the source becomes active. The Smart Alarm
remains active as long as the source is active.
Manual Sources
Parameter
Setting
SA Num
Type the number (from the
Smart Alarm States
table) of the
Smart Alarm
for
which this source is an input.
