When enabled, the RBX function automatically clears an instrument alarm after an alarm parameter has
returned to its normal operating range, buffered by a user specified deadband (hysteresis). The deadband
values are specified in items 166 (Pressure 1), 167 (Temperature), 169 (Flow Rate), and 459 (Pressure 2).
When disabled, the alarms remain in their current state until the user manually clears it.
