TEMPERATURE ALARM HOLDOFF
This variable is the sometimes known as deadband or hysteresis. It is the amount by which the alarm limit must
be cleared before the alarm is deactivated. For example, if the High temperature alarm setpoint is 10 and the
temperature alarm holdoff is 1, the temperature must return to a value of 9 before the High temperature alarm is
deactivated. This variable is entered when configuring the tank point and cannot be modified from Operate
DENSITY ALARM - COMPOSITE DENISTY ALARM
This variable is a composite value that displays a coded variable representing the highest priority density alarms
for the tank. Possible values are Normal, High or Low. FuelsManager calculates this alarm based on the current
density and the alarms limit configured for the tank point
DENSITY HIGH LIMIT - CURRENT HIGH DENSITY LIMIT
This variable is the limit for a High density alarm. If the tank density exceeds the High Alarm value, then a High
alarm is activated. This variable is entered when configuring the tank point, but can be modified from Operate by
a user with sufficient privileges
DENSITY LOW LIMIT - CURRENT LOW DENSITY LIMIT
This variable is the limit for a Low density alarm. If the tank density falls below the Low Alarm value, then a Low
alarm is activated. This variable is entered when configuring the tank point, but can be modified from Operate by
a user with sufficient privileges
DENSITY ALARM HOLDOFF
This variable is the sometimes known as deadband or hysteresis. It is the amount by which the alarm limit must
be cleared before the alarm is deactivated. For example, if the High density alarm setpoint is 10 and the density
alarm holdoff is 1, the density must return to a value of 9 before the High density alarm is deactivated. This
variable is entered when configuring the tank point and cannot be modified from Operate
FLOW ALARM - COMPOSITE FLOW ALARM
This variable is a composite value that displays a coded variable representing the highest priority flow alarms for
the tank. Possible values are Normal, High or Low. FuelsManager calculates this alarm based on the current
flow and the alarm limits configured for the tank
FLOW HIGH LIMIT - CURRENT HIGH FLOW LIMIT
This variable is the limit for a High flow alarm. If the tank flow exceeds the High Alarm value, then a High alarm
is activated. Please note that FuelsManager compares the value of the flow variable regardless of it's sign,
meaning that a flow of -10000 gpm would trigger a high flow alarm if the High flow limit was 9999. This variable
is entered when configuring the tank point, but can be modified from Operate by a user with sufficient privileges
FLOW LOW LIMIT - CURRENT LOW FLOW LIMIT
This variable is the limit for a Low flow alarm. If the tank flow falls below the Low Alarm value, then a Low alarm
is activated. Please note that FuelsManager compares the value of the flow variable regardless of it's sign,
meaning that a flow of -10000 gpm would trigger a high flow alarm if the High flow limit was 9999. This variable
is entered when configuring the tank point, but can be modified from Operate by a user with sufficient privileges
