Battery Discharge Test
Perform the test procedure in Table 2-8 only when the battery current is
less than 5 Amps per string. Refer to Table 2-7 on the procedures for
checking current levels.
Table 2-8: Battery Discharge Test
Step Action
1 Turn the BATT TEST switch on the MAP ON (Figure 2-9). The rectifier output voltage and current
should decrease by approximately 10% as the batteries assume the load. Alarms for the MAP may
occur.
2 Measure the individual battery string current using the clamp-on DC current probe and DMM. The
battery discharge current in each string should be approximately the same (within +
5 amps).
3 Turn BATT TEST switch OFF.
CAUTION
Failure to turn off the MAP BATT TEST switch before leaving
the site will result in low battery capacity and reduce battery life.
