Alarms include high and low voltage, high current, and low battery.AC System MonitoringMonitors a single AC voltage, current, and frequency. Alarms include high and low voltage, high current, and high and low frequency.Bilge & Tank MonitoringTwo inputs can be configured as a bilge or tank monitor. As a bilge input, monitoring functions include pump active, 24 hour cycle count, 24 hour average cycles, and total cycles. Alarms can be set for both the minutes of run time in the last hour and the number of 24 hour cycle counts.
