Using Diagnose Mode
To run diagnose mode, first remove power from the PES indoor unit and DISCONNECT THE IFL CABLE FROM
THE REAR OF THE PES 5000 VERSION 3. Note that the IFL cable has to be disconnected in order to run the
diagnostic IFL loopback test successfully.
Connect a site commissioning computer to the PES 5000 version 3 service connector marked MAINTENANCE. Apply
power to the site commissioning computer and the PES indoor unit. Select 2 for PES Model X000 when the screen
displays:
Enter Config Editor Mode
1) Type 1/Type 2 (IOC) mode
2) Model X000 series (IFM) mode
3) Exit
Enter choice (1, 2, or 3) ?
At the main menu, enter SWITCH <ENTER> to select the SWITCH function. Use the < key to move the X under DIAG
so the display shows:
Serial No. XXXXXXXXXX Rev Lev. XXXX
DIAG-----NORMAL-----COMM-----INSTALL
X
Use ’<’ and ’>’ keys to move switch
Hit <ENT> to exit.
Exit the switch function. The PES 5000 resets, performs self-tests and begins a series of diagnose mode tests.
During DIAGNOSE mode the LCD display shows the words “DIAG Mode” and a code number.
DIAG Mode
NN/SS Pass 0001
Where NN is the test number in table 5 and SS is the sub-test number in table 10. Diagnose mode progresses thru the tests
in the order listed in table 5. When DIAGNOSE mode starts, the status LED (figure 8 on page 9) stops glowing.
Within approximately four minutes, the diagnose mode test should complete successfully as indicated by changes in the
LCD display. The unit returns to NORMAL mode. The LCD display returns to giving the PC: and IF: codes in the
locations shown in figure 8 on page 9. Remove power from the unit and re-attach the IFL cable. Re-apply power and
verify normal operation
If DIAGNOSE mode fails, the status LED glows with a red color and the number of the test that failed is shown in the
LCD display. Table 10 lists the numbers and names of these tests. When the unit fails, it can only be set back to normal
by pressing the SELECT button on the front panel. If DIAGNOSE mode fails, replace the PES 5000 version 3 indoor
unit.
Note that DIAGNOSE mode does not test user ports 3 and 4. If DIAGNOSE mode passes yet there are problems on ports
3 or 4, replace the PLC.
NOTE: As of this writing, the PES 5000 version 3 is not capable of doing Remote Field Diagnostics (RFD) as
described in CSB 201A.
