Diagnostics History
Whenever a problem is detected by the self-diagnostics feature that
causes the unit to shut down, the event is recorded and stored in NVM.
This is particularly helpful when dealing with intermittent failures but not
so helpful if the unit is always shutting down.
The diagnostics history pages are retrieved by pressing the "DISPLAY",
"5", "VOL –" and "POWER" buttons in sequence on the remote commander
when the unit is off. The diagnostics history page will appear as shown in
Figure 5-3
Note that a running count is kept anytime one of the detection circuits is
activated. This running count will continue until it is reset. This is performed
by pressing the "8" key on the remote followed by the "0" key. This should
always be done in order to clear the history and provide a clean table for
future use.
The diagnostics page also contains 3 sets of 5-digit numbers. The first
set, beginning at the left, indicates the number of hours, in decimal format,
that the set has been operating. The next set is the boot count. This is the
number of times the unit has been turned on. The third set is the number
of hours the panel has been operating. This number can be reset to zeros
by pressing the "7" key followed by the "0" key. Only the panel hours will
be reset.
NOTE: Although a 13X BALANCER error is displayed it is not used in this
model.
