Troubleshooting
The Powermonitor Software will alert the system operator to conditions that
will cause incorrect operation of the software. This is accomplished by
displaying messages at the bottom of the computer screen and, in some
cases, annunciating an audible alarm.
Provided below are detailed descriptions of possible the Powermonitor
Software error conditions, their potential sources, and recommended steps to
rectify each problem.
ERROR MESSAGE POSSIBLE CAUSE SOLUTION
Password Not Correct Operator incorrectly entered password.
Operator forgot password.
Disk file in which the Powermonitor Software saves
the password may have been corrupted.
Re-enter the password.
Re-install the software to reset the password to the
default value of 0
OR
Contact the Allen-Bradley Technical Support
Division.
Serial Port Setup Error One or both of the computer’s communication ports
is configured incorrectly. Refer to the operation manual for the computer.
REMOTE COMMUNICATION ERRORS Perform a systematic check of each possible cause. If you are using the Powermonitor Software for the
first time, there is a high probability the difficulty is caused by one of the first three possible causes. If you
are a seasoned user, the difficulty is likely to be the first, fourth, or fifth possible cause.

1. Fault with the communications link between
the computer and the Powermonitor (including
communications wiring, modem configuration
or correct operation, etc.)
See Page 8–2 for continued possible cause
listings.
RS-232. Perform the following checks:
Check that the cable to the computer is inserted in
the correct communication port.
Check that the cable is not faulty.
Make sure the RS-232C transmit and receive wires
are connected to correct locations on the
Powermonitor(s).
Verify that the correct communications mode
(RS-232C) is selected at the Powermonitor(s).
RS-485. Perform the following checks:
Make sure a 25 pin conductor cable is installed
between computer and RS-232C to RS-485
converter.
Check that the supply power is applied to RS-232C
to RS-485 converter device.
Make sure DATA+ line on the converter is
connected to DATA+ line on each Powermonitor
and DATA – line on converter is connected to
DATA– line on each Powermonitor(s).
Verify that the correct communications mode
(RS-485) is selected at the Powermonitor(s).
