4.5.5 Flexible Limits
General notes
CAUTION!
Hazards due to improper configuration of protective functions
Flexible Limits must not be used for protective functions, because the monitoring
function is not guaranteed beyond an exceeding of 320 %.
It is not possible to monitor temperature values in Degree Fahrenheit and pressure
values in psi. Although parameters
╚═▷ 3631 or ╚═▷ 3630 are configured to a value
display in °F or psi, flexible limit monitoring always refers to the value in Degree Celsius
or bar (J1939 protocol: kPa).
This control unit offers 40 flexible limits. They may be used for "limit switch" functions of
all measured analog values. It is possible to choose between alarm (warning and
shutdown) and control operation via the LogicsManager.
If an alarm class is triggered, the display indicates "Flexible limit {x}", where {x}
indicates the flexible limit 1 to 40, or the text configured using ToolKit and the logical
command variable "15.{x}" will be enabled.
The flexible limits 25 through 32 are configurable additionally with a 'Fallback time' e.g.,
for load shedding.
The flexible limits 33 through 40 are disabled during idle mode operation (refer to ╚═▷
“4.4.1.4 Idle Mode” ).
