While conducting a site assessment and power usage study to determine the battery backup time required before the replacement, Brian Tenters, Eaton’s Northeast area supervisor, found that MWO had reduced its equipment since the UPS was first installed. And, Tenters determined that 90 minutes of runtime—rather than the originally slotted 170 minutes— would be more than sufficient for the organization.
Tenters and another field technician, Phil Percoski, trekked to the top of Mt. Washington in August with four new strings of batteries for the observatory. And, Tenters and Percoski performed comprehensive preventive maintenance on the 9355 as part of a new, two-year service agreement. Under the contract, Eaton will provide after-hours and preventive maintenance on the UPS and batteries twice a year, as well as an eight-hour response time in the event of an alarm.
MWO also uses Eaton’s PredictPulse remote monitoring service, which provides real-time monitoring of more than 100 UPS and battery alarms. Monthly reports on the UPS status include information on voltages, loads, temperature and humidity and summarize battery events, availability percentage, comparative status against recommended specification and the top 10 performance and environmental parameters. If any type of power anomaly is detected, MWO will be notified immediately.
An additional benefit of PredictPulse is that Eaton remotely monitors the UPS and batteries at all times. This allows for some issues to be resolved remotely— often before a customer even knows a potential problem exists. In instances where a site visit is required, Eaton will automatically dispatch a technician within the specified response time window. The upgrade to PredictPulse came with an Eaton environmental monitoring probe too, which Roger Pushor, a weather observer and IT specialist at MWO, deems a “super bonus.” The small, single module enables remote monitoring of environmental conditions such as temperature and humidity.
With a more compact UPS solution, real-time system updates and the addition of an environmental monitoring probe, MWO is in an excellent position to preserve its 80-year weather history and capture as much data as possible during extreme weather.
