The next step is to check power and voltages as indicated below in Section 9.1.1. Once
Primary AC Power and Battery Backup Power are verified, the technician should refer to
Table 9.1, “Troubleshooting Checklist and Flow Chart” and the remaining sections of this
Chapter to assist with more detailed troubleshooting guidelines.
9.1.1 Power Verification
The following power components of the HPSA-7100-R should be verified if the HPSA or
any of its sub-assemblies lose power.
9.1.1.1 AC Power
Verify AC Power is applied to the HPSA. If AC Power is not available at the input to the
HPSA, the HPSA should be powered by the Backup Batteries.
Troubleshoot as follows:

Verify status of AC circuit breaker/disconnect

Verify 110 - 240 VAC at input to HPSA TB6 L-N-G

Verify Backup Battery status and voltages as indicated in Section 9.1.1.2
9.1.1.2 Battery Voltage
Battery Monitoring consists of three functions: Battery Low, Battery OK and Low Voltage
Disconnect (LVD). The battery voltage is queried periodically using a two-stage test. The
first stage applies a constant current of 4A, the second stage applies a constant voltage of
54.6 V. If the battery string voltage is less than 54.5 VDC (13.63 V/battery, 2.27 V/cell)
then the battery charger will turn on and charge the batteries.
If the battery string voltage is approximately 46 VDC, a low voltage indication is
activated, and in an effort to preserve the batteries from deep discharge, the system will be
shut down by the controller in approximately three minutes (if a message is not in
progress). If a message is in progress, the system will remain active until the message is
complete.
If an LVD event occurs, the system power will not be restored until the battery voltage is
between 47-48 VDC (11.87 V/battery,1.98 V/cell). When correct voltage conditions are
met, the supply voltage automatically turns on shortly after the AC Mains charging
voltage exceeds the under-voltage threshold.
If there is no AC Voltage into the HPSA, perform the following:
•
Determine the Low or No Battery status as indicated on the PDB, AMB or
scrolling thru the Control Panel on the HPSA
•
Measure battery stack voltage on the PDB TB1 and 2
•
If no DC voltage is present on the PDB, verify the Fuse in line with the Battery’s
positive (+) voltage is not blown
•
If battery stack voltage is less than 48VDC, disconnect and test each battery
individually for proper voltage (12VDC)
•
Replace batteries as necessary
