4.9.6 OPEN RTD SENSOR
The 469 has an Open RTD Sensor Alarm. This alarm will look at all RTDs that have either an alarm or trip pro-
grammed 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 recom-
mended that if this feature is used, the alarm be programmed as latched so that intermittent RTDs are detected
and corrective action may be taken.
4.9.7 RTD SHORT/LOW TEMP
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 pro-
grammed as latched so that intermittent RTDs are detected and corrective action may be taken.
