ED830
Sales Literature Instruction Manual
The ED830 is a four zone level alarm control unit, each zone is totally independent, with separate circuitry, switches, fuses, output relays, lamps, etc. In addition the zone wiring is fault monitored. Both on and off delay times can be adjusted for each zone giving a pump run on facility and avoiding nuisance alarms due to movement of the vessel. With the flexible circuitry the ED830 allows additional float switches to be fitted without the need for modification.
