Chapter 8  Diagnostics and Fault Clearing
Displaying Faults from the Monitor Block Screens 
From the HHM main menu, select either F1 (Monitor Block) or F2 (Monitor/Control
Reference).  Both functions access the same set of display screens for the Remote I/O
Scanner.
MNTR           1
143#0.2 %I     1
STS 0
> ref force diag
From any Monitor screen, press F4 (diag) to display diagnostics for the  remote drop.
The Hand–held Monitor displays the first fault it encounters.  For example:
DIAG           3
143#0.3 #I    33
OVERCURRENT
mon          nxt
The Remote I/O Scanner stores faults (up to 64) in time sequence, not reference
sequence.  If the circuit that was shown on the Monitor screen when you pressed F4
(diag) has a fault, that fault appears.  If there is no fault on that circuit, the Hand–held
Monitor displays the oldest fault stored by the Remote I/O Scanner instead.
Displaying Additional Faults
Pressing F4 (nxt) displays additional remote drop faults in the same sequence in which they
occurred
.  For example, if the fourth oldest fault is being shown, pressing F4 (nxt)
displays the fifth oldest, and so on.
Multiple  Faults for the Same Circuit
If a circuit has multiple faults that occurred at different times, they will probably not be
displayed one after another.  To see whether a reference has additional faults, use the
F4 (nxt) key to go through the fault screens.  Watch the reference identification on line
2 for the specific circuit you are interested in.
Returning to the Monitor Screen
Pressing F1 (mon) returns you to the Monitor screen you started from.
