DIAGNOSTIC MESSAGES
FOR OPERATORS
In the event of a Trip, Alarm, or Start Block, some of the Actual Value messages are very helpful in diagnosing the cause of the condi-
tion. The SR469 will automatically default to the most important message. The hierarchy is Trip and PreTrip messages, Alarm, and
lastly, Start Block Lockout. In order to simplify things for the operator, the Message LED (indicator) will flash prompting the operator to
press the [NEXT] key. When the [NEXT] key is pressed, the SR469 will automatically display the next relevant message and continue to
cycle through the messages with each keypress. When all of these conditions have cleared, the SR469 will revert back to the normal
default messages.
Any time the SR469 is not displaying the default messages because other Actual Value or Setpoint messages are being viewed and
there are no trips, alarms, or blocks, the Message LED (indicator) will be on solid. From any point in the message structure, pressing the
[NEXT] key will cause the SR469 to revert back to the normal default messages. When normal default messages are being displayed,
pressing the [NEXT] will cause the SR469 to display the next default message immediately.
EXAMPLE:
If an Overload Trip occurred, an RTD alarm may also occur as a result of the overload, and a lockout time would be associated with the
Trip. The SR469 would automatically default to the Cause of Last Trip Message at the top of the LAST TRIP DATA queue of A1
ACTUAL VALUES. The Message LED (indicator) would flash. Pressing the [NEXT] key would cycle through the TIME and Date Stamp
information as well as all of the Pre-Trip Data. When the bottom of this queue is reached, an additional press of the [NEXT] key would
normally return to the top of the queue . However, because there is an alarm active, the display will skip to the alarm message at the top
of the ALARM STATUS queue of A1 ACTUAL VALUES. Similarly, another press of the [NEXT] would cause the SR469 to skip to the
Start Block Lockout message at the top of the START BLOCK queue A1 ACTUAL VALUES. Finally, another press of the [NEXT] key
will cause the SR469 to return to the original Cause of Last Trip message, and the cycle could be repeated.
When the [RESET] has been pressed, the hot RTD condition is no longer present, and the lockout time has expired, the display will
revert back to the normal Default Messages.
