When set to Alarm or Latched Alarm, this element monitors all the RTDs that are either
programmed as Alarm or Trip or Configurable and generates an alarm if any of the RTDs
are detected as Open or Shorted. Upon detection of an RTD Open or Shorted condition, the
element also asserts the RTD Trouble PKP and RTD Trouble OP and operates the assigned
output relay.
