FUNCTION:
The SR469 has an Open RTD Sensor Alarm. This alarm will look at all RTDs that have either an alarm or trip programmed and deter-
mine 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.

FUNCTION:
The SR469 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
o
C). Any RTDs that do not have a trip or alarm asso-
ciated 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.
