These alarms can:

• Turn on an LED, LCD Indicator or relay output

• Record an event in the event log

• Trigger an event such as a remote alarm or dial an emergency number via scripts

Extensions for Customer Applications: standard or to order

The Genius meter introduces the concept of Extensions to the revenue metering world. The increasingly complex nature of revenue metering has necessitated the development of exciting new programming tools that allow customers to tailor the meter for specific applications. Using

“EziScript”, a scripting language developed by EDMI, complex register manipulations can be performed allowing sophisticated changes to the meter operation. EDMI offers custom Extension writing services. New Extensions are constantly under development - contact us to find out the latest updates

Examples of currently available Extensions are:

• Send SMS at percentage of maximum demand

• Average power factor for billing period

• LCD menu system

• Magnetic tamper detection

• Power factor control extension

• Maximum demand control of loads via pulsing outputs

• Average voltage, current, unbalance, THD etc

• Voltage sag / swell or power outage

• Power factor / power quality

• Voltage quality

• Send SMS on equipment failure alarm

Software

• EziView Windows software (optional), can be used for programming and reading the meter

• EziView also allows offline configuration of tariff programs and all meter parameters, for later upload
