The 469 has an Open RTD Sensor alarm. This alarm will look at all RTDs that have
either an alarm or trip programmed and determine if an RTD connection has been
broken. Any RTDs that do not have a trip or alarm associated with them will be
ignored for this feature. When a broken sensor is detected, the assigned output
relay will operate and a message will appear on the display identifying the RTD that
is broken. It is recommended that if this feature is used, the alarm be programmed
as latched so that intermittent RTDs are detected and corrective action may be
taken.

The 469 has an RTD Short/Low Temperature alarm. This alarm will look at all RTDs
that have either an alarm or trip programmed and determine if an RTD has either a
short or a very low temperature (less than –50°C). Any RTDs that do not have a trip
or alarm associated with them will be ignored for this feature. When a short/low
temperature is detected, the assigned output relay will operate and a message will
appear on the display identifying the RTD that caused the alarm. It is recommended
that if this feature is used, the alarm be programmed as latched so that intermittent
RTDs are detected and corrective action may be taken.
