190 Info. The controller module's supercapacitor pack has started charging.
This change met a condition to trigger the auto-write-through feature, which has disabled write-back cache
and put the system in write-through mode. When the fault is resolved, event 191 is logged to indicate that
write-back mode has been restored.
Recommended actions:
• If event 191 is not logged within 5 minutes after this event, the supercapacitor has probably failed and the
controller module should be replaced.
191 Info. The auto-write-through trigger event that caused event 190 to be logged has been resolved.
Recommended actions:
• No action is required.
192 Info. The controller module's temperature has exceeded the normal operating range.
This change met a condition to trigger the auto-write-through feature, which has disabled write-back cache
and put the system in write-through mode. When the fault is resolved, event 193 is logged to indicate that
write-back mode has been restored.
Recommended actions:
• If event 193 has not been logged since this event was logged, the over-temperature condition probably still
exists and should be investigated. Another over-temperature event was probably logged at approximately
the same time as this event (such as event 39, 40, 168, 307, 469, 476, or 477). See the recommended
actions for that event.
193 Info. The auto-write-through trigger event that caused event 192 to be logged has been resolved.
Recommended actions:
• No action is required.
