Troubleshoot with LEDs
Chapter 11
11-2
Table 11.A shows how to interpret QDC module LEDs. The QDC module
monitors its own operation and reports detected conditions by illuminating
its LEDs in the following combinations:
Table 11.A
LED Indicator Conditions
ACTIVE FAULT COMM Condition: We recommend that you:
Flashing Off Off PowerĆup. The QDC module has completed its powerĆup diagnosĆ
tics, the QDC module hardware and firmware are OK, and the QDC
module is awaiting download of the MCC block.
Download the MCC block. ProĆSet 600 downloads
the MCC when you switch your PLCĆ5 processor
from program mode to run mode.
Flashing Red Yellow Software Error. The QDC hardware and firmware are OK, the last
BTW received by the QDC module had a recognizable block ID, but
the last MCC received by the QDC module contained a programĆ
ming error.
1. Fine and correct the MCC programming error.
2. Use the MCC download procedure in chapter 3
to download corrected data to the QDC module.
Flashing Red Off Software Error. The QDC hardware and firmware are OK, but the
last BTW received by the QDC module did not have a recognizable
block ID, and the last MCC received by the QDC module contained
a programming error.
1. Find and correct the MCC programming error.
2. Use the MCC download procedure in chapter 3
to download corrected data to the QDC module.
3. Verify block IDs in your BTW data files.
Flashing Flashing Flashing You put the Run/Calibrate jumper (E1) in the Calibrate position. Put the E1 jumper in the Run position (chapter 2).
Green Off Yellow Normal operation. The QDC hardware and firmware are OK, no
programming errors exist, and the last command block
received by the QDC module had a recognizable block ID.
Do nothing.
Green Off Off Software Error. The QDC hardware and firmware are OK, no proĆ
gramming errors exist, but the last command block received by the
QDC module did not have a recognizable block ID.
Verify block IDs in your BTW data files.
Green Red Yellow Limited operation. The QDC hardware and firmware are OK, the
last command block received by the QDC module had a recognizĆ
able block ID, but a programming error(s) exists.
1. Find and correct the programming error.
2. Use the download procedure in chapter 4 to
download corrected data to the QDC module.
Green Red Off Software Error. The QDC hardware and firmware are OK, but a
programming error(s) exists, and the last command block
received by the QDC module did not have a recognizable block ID.
1. Find and correct the programming error.
2. Use the download procedure in chapter 4 to
download corrected data to the QDC module.
3. Verify block IDs in your BTW data files.
Off Off Flashing Communications Error. The QDC hardware and firmware are OK,
but the module is not completing continuous transmission of status
data blocks to the host PLC processor. The QDC module is inoperĆ
able until continuous BTR communication is reĆestablished with the
host PLC processor.
1. Verify your PLC is in run mode.
2. Reseat your QDC module in the I/O chassis.
3. Check for PLC ladder programming problems.
Off Red Yellow
or Off
Hardware fault. The QDC module is inoperable. 1. Cycle power to the QDC module.
2. Replace the QDC module
3. Return it for factory repair.
We recommend that you re-calibrate your QDC module every two years.
To calibrate it yourself, refer to the Reference Manual, 1771-6.5.88 (dated
November 1992), for calibration instructions. Otherwise, return it to the
factory with this order number: 1771-QDC/(Rev Letter) – CAL.
