The totalization alarm functions
and
allow the user to notify when a total value is reached.
The alarm defined as Totalization Minimum Value Alarm
) is set when the totalization value
goes below the configured setpoint.
The alarm defined as Totalization Maximum Value Alarm (
) is set when the totalization value
goes above the configured setpoint.
As the totalization value can indicate up to 99999 99999 (or -9999 99999) the set point values
behave the same way. If the adjusted SP goes above 99999 (or below -9999) the second SP part is
displayed allowing the operator to see values up to 99999 99999 (or -9999 99999).
The flags HIGH and LOW identify if the part being displayed is the SP most significant part (HIGH)
or the least significant part (LOW).
The totalization alarm (SP) is defined through the values SPA1 and SPA2. This two parameters
behave different from other parameters. The Back key allows the operator to change the SP
decimal digit to be set.
