Powerware 9315 operation manual Relay Interface Module

Relay Interface Module

An optional Relay Interface Module (RIM) uses relay contact closures to indicate the operating status and alarm condition of the UPS system. A maximum of two monitoring accessories (RMPs, RIMs, or SCMs) can be installed. See Table 1 for the number of accessories permitted. Figure 21 shows the RIM with its four 15-pin connectors labeled J1 through J4.

The RIM can provide these signals:

·UPS AVAILABLE (pins 1 and 12) Contacts are closed when the UPS is offline.

·UPS OFF LINE (pins 3 and 13) Contacts are closed when the UPS is operating in Normal mode.

·UTILITY FAILURE (pins 6 and 15) Contacts are closed when Utility Failure is detected.

·BATTERY WEAK (pins 5 and 14) Contacts are closed when approximately 2 minutes of battery time is remaining, before the critical load is lost.
