Refer to Table 9.1, “Troubleshooting Checklist and Flow Chart” and the remaining
sections of this Chapter for troubleshooting guidelines.
Follow appropriate safety precautions when troubleshooting live circuits.
TABLE 9.1
Troubleshooting Checklist and Flow Chart
TROUBLE/INDICATOR TROUBLESHOOTING ACTION
General Verify the circuit boards in the Control Panel Assembly are securely seated.
General Inspect all internal wiring for defects; verify connections are secure.
General
Verify all battery connections are correct, corrosion free and tight. Refer to
Chapter 5, Installing the Batteries for correct battery wiring.
PDB: AC Power LED
D5 (AC LED) on the PDB will be illuminated solid GREEN during normal
operation.
If the D5 LED is not lit:
•
Refer to Section 9.2.4, HPSA PDB (A4) Test Points and Voltages.
PDB: 15VDC LED
D18 (15V LED) on the PDB will be illuminated solid GREEN during normal
operation.
If the D18 LED is not lit:
• 36VDC coming to the PDB from the AC PS Switch on PDB J2
pins 5 and 4 (Gnd)
PDB:
Amplifier-1 LED
D26 (Amp-1 LED) on the PDB will be illuminated solid GREEN during normal
operation.
If the D26 LED is not lit, power is not going to the Amplifier Board from the PDB.
Check the following:
•
PDB TB1 (+) and TB2 (-) for 48VDC coming into the PDB
• TB3 pins 1 (+) and 2 (-) for 48VDC from the PDB to the Amplifier
Board.
PDB:
Low Battery Volt. LED
Low Battery LED D24 on the PDB will be OFF if the battery stack voltage is
greater than approximately 46 - 46.5 VDC.
D24 will be illuminated solid RED if the battery stack voltage is less than
approximately 45.5 - 46VDC. If the LED is lit:
•
Measure battery stack voltage
•
If battery stack voltage is less than 48VDC, disconnect and test each battery
individually for proper voltage (12VDC nominal).
•
Replace batteries as necessary.
AMB:
AC Voltage LED
D10 (No AC LED) on the AMB will be OFF during normal operation and
illuminated when the HPSA has an AC input.
If the D10 LED is illuminated, refer to Section 9.2.4, HPSA PDB (A4) Test Points
and Voltages.
