3.28 Limit Value Monitoring (Function Group LIMIT)
The limit value monitoring function (LIMIT) monitors measured values which have
been obtained from the analog measured data inputs.
3.28.1 Enabling or Disabling the Limit Value Monitoring Function
The limit value monitoring function can be disabled or enabled via setting
parameters.
3.28.2 Monitoring the Linearized Measured DC Values
The direct current, linearized by the analog measured data input, is monitored by
two stages to determine if it exceeds or falls below set thresholds. If any of the
measured values exceed or fall below the thresholds then a signal is issued after
the associated time-delay has elapsed.
