8–2 889 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL
ENVIRONMENTAL HEALTH REPORT CHAPTER 8: MAINTENANCE
Environmental Health Report
Prolonged exposure to harsh environments and transient conditions that exceed those
stated in Section 1 - Specifications reduce the life of electronic products. The 889 has an
Environmental Awareness Module (EAM) to record environmental data over the life of the
product. The patented module measures temperature, humidity, surge pulses and
accumulates the events every hour in pre-determined threshold buckets over a period of
15 years. The user can retrieve this data in the form of a histogram using EnerVista Setup
Software to ensure any change in the operating condition of the installed fleet is identified
quickly so remedial action can be taken.
