ASCO 5101 Engine Start Monitoring System

Monitor Back-up Generator Start Signals and Prevent Outages

An NEC®-compliant engine-generator starts automatically when it receives a start signal from an automatic transfer switch. If signaling wires are damaged, an engine will not receive the start signal needed to begin supplying mission-critical power. Without Engine Start Circuit monitoring and control, facility operators will never know when wiring is compromised, placing the facility at risk for an outage.
