
Talker Mode:Error-Timeout occurred is recorded, for systems operating in
Poll/Standalone mode, when five minutes goes by without the system receiving a valid
poll from the Harriman Dispatch Center. This message is also recorded for systems
not connected to Harriman. This entry appears each time the talker-mode setting
automatically changes due to a loss of communications with Harriman. If the
talker-mode setting is talk-on-defect, it changes to talk-freely. If the setting is already
talk-freely, it stays talk-freely.

Talker Mode:Timeout condition corrected is recorded when a valid poll is received
after a prior Talker Mode:Error-Timeout occurred event was recorded. This entry
appears each time the system restores its prior talker-mode setting as a result of
reestablishing communications with the Harriman Dispatch Center. The talker-mode
setting that is restored is the one in existence just before the
Talker Mode:Error-
Timeout occurred event was recorded.

Talker Mode:NAK condition corrected is recorded when a ZA or ZU message
transmission is acknowledged by the Harriman Dispatch Center after a prior Talker
Mode:Error-NAK occurred event was recorded. This entry appears each time the
system restores its prior talker-mode setting as a result of processing an acknowledged
ZA or ZU message transmission. The talker-mode setting that is restored is the one in
existence just before the
Talker Mode:Error-NAK occurred event was recorded.

Wind Monitor:Error-Direction suspicious is recorded when the wind monitor reports
a constant wind-direction reading for at least 30 minutes.

Wind Monitor:Direction restored is recorded when the wind monitor reports a
different wind-direction reading than the last reported one after a prior Wind
Monitor:Error-Direction suspicious event was recorded.

Wind Monitor:Error-Speed suspicious is recorded when the wind monitor reports a
constant wind-speed reading for at least 30 minutes.

Wind Monitor:Speed restored is recorded when the wind monitor reports a different
wind-speed reading than the last reported one after a prior Wind Monitor:Error-Speed
suspicious event was recorded.

Wind Monitor:Error-Loss of communications is recorded when the wind-monitor
hardware fails to produce a valid response for at least two minutes.

Wind Monitor:Communications restored is recorded when the wind monitor
correctly responds to a system poll after a prior Wind Monitor:Error-Loss of
communications event was recorded.
Wind-monitor support must be enabled in order for the system to post any of the wind-monitor
events. You can enable wind-monitor support by using the Polling System submenu of the
Setup menu.
Chapter 11 - Serial Interface tells how to set this value.
