5.0MAINTENANCE

5.1General

The following is a list of general preventive maintenance procedures which should be performed periodically as required according to the environmental conditions and customer maintenance policy to ensure trouble free operation of the Helios DC System 4000/48:

•clean all ventilation openings

•if these are used, clean or replace the air filters on the rectifiers

•tighten all electrical connections

•check for hot fuses or breakers (loose, undersized or overloaded)

•verify alarms and alarm thresholds

•verify calibration settings

•verify rectifier settings

The voltage and alarm settings of the controller and rectifiers are based on the type of batteries used with the power system. The recommended settings for various types of batteries can be found in SL-60026, Voltage Level Limits for Power Plants, Rectifiers and Controllers. If unlisted models of batteries are used, it may be necessary to follow specific customer or manufacturer requirements.

The following is list of the tools and test equipment required to adjust the equipment in the Helios DC System 4000/48:

•a potentiometer screwdriver, Bourns No. 60 or equivalent

•a digital voltmeter, Fluke 8050A or equivalent

•a dummy load, 5 kVA
