How to Run MOSS Diagnostics
These tests can be run without stopping the cus-
tomer's application.
Ÿ Error conditions will result in a control panel
code being displayed. Actions for these
codes are defined in “3745 Control Panel
Codes” on page 1-15.
or
Ÿ
Some errors will result in a reference code at
IML completion. These types can also be
recognized by the panel code displaying F0D.
Refer to “Using Reference Codes” on
page 1-14 for action.
Ensure that the MOSS is offline or alone (look at
MOSS Status Area on the second line of the
console screen) and that service mode (panel) is
0 or 1.
From the 3745 Console
1. On the 3745 console, select Menu 1 (see PF
key line).
2. In Menu 1, type IML in the selection area for
IML MOSS.
3. After approximately 2 minutes the console will
be re-initialized with the Channel
Enable/Disable screen which indicates that a
successful run of MOSS diagnostics and the
MOSS IML have been completed.
4. If the console has not been re-initialized, an
error was detected.
From the Control Panel
1. Set the function to MOSS IML:
a. Press Service until the number 0 or 1 is
displayed in the service window. (No
bypass of MOSS diagnostics.)
b. Press Validate.
c. Press Function until the number 1 is dis-
played in the function window.
d. Press Validate.
2. If after approximately 2 minutes the control
panel displays code F0F, the MOSS diagnos-
tics and a MOSS IML have been successfully
completed. Code F0E can be displayed if the
MOSS was previously alone (that is not in
offline mode).
3. If any other code is displayed, an error was
detected.
