enabled to perform this function). Display the
circuit you want to force. Press F3 (force).
For a discrete circuit , the HHM displays:
m o n o n o f f r e l e s
Press F2 (on) or F3 (off) to force the circuit. The
forced state appears on line 3. To release the force,
press F3 (reles).
For an analog circuit , the HHM displays:
S T S 4
f o r c e r e l e a s e
Press F2 (force) to force the circuit. The screen
next displays:

force/release screen.
Displaying and Clearing Remote Drop Faults
To display diagnostics for a circuit, press F4 (diag)
from the Monitor screen. If there is a fault, it
appears on line 3. For example:
D I A G 3
1 4 3 # O . 3 % I 3 3
O V E R C U R R E N T
m o n n x t
If there is no fault on the circuit you are
monitoring, the Hand-held Monitor searches the
Remote I/O Scanner’s internal fault table to see
whether there are any faults on the remote drop.
If there are any uncleared faults on the remote
drop, the HHM displays the fault that occurred
first (the oldest fault). For example:
D I A G 3
1 4 3 # O . 2 % A I 1
U N D E R R A N G E
m o n n x t
The HHM identifies the location where the fault
occurred (on line 2). From this screen, you can
display additional faults on the remote drop by
pressing F4 (nxt). Faults will appear in the same
sequence in which they occurred. For example,if the
fourth oldest is being shown, pressing F4 (nxt)
displays the fifth oldest, and so on.
To return to the Monitor screen you started from,
press F1 (mon).
Clearing Faults
After correcting fault–causing conditions, you can
return to the Block/Bus Status menu to clear all
fault messages for the remote drop. (The Clear
Block Faults function must be enabled to use this
feature).
