 Solidstate
Controls, Inc. (SCI) Preventive and Predictive Maintenance Service
(PPM) is custom designed to allow clients to keep their battery
charger, inverter, UPS system and other products supplied by SCI,
in the best operational condition possible. A regular PPM will minimize
downtime caused by:
- Dirty or corroded components
- Components with excess wear
- Damage due to adverse environmental conditions
- Components reaching the end of their life
- Improper alignment of circuit boards and/or assemblies
- Other identified problem areas

Testing |
| |
Battery maintenance is limited
to visual inspections, VPC/VPB readings, and intercell connection
tightness. Where possible, to ensure proper operation of the
systems under transfer of the load to battery, after permission
from the client is obtained, the battery charger supplying the
UPS will be interrupted or lowered in output voltage to cause
the system to operate from the batteries. The system will be
returned to a normal operational state prior to completing discharge
of the battery. Equalize and float voltages will be adjusted
as necessary to return them to their desired values. System
battery functional testing should not be used in lieu of dedicated
maintenance and inspection testing of the battery system as
outlined elsewhere in this brochure and/or battery manufacturer's
installation guides. |
