Z Soft Switch

• Totalization and External Pulse Input Scaling

– Enables combinin data from u to 5 meters

• 4 external meter inputs plus the kV2 metered data

• External inputs require use of the Multiple I/O option board

“ ” – --

• Add or subtract inputs with the same engineering units

• May use one totalization channel as input to a secondtotalization channel

– Enables data scaling of external pulse inputs

• External inputs may be recorded and displayed as unscaled

raw pulse counts without the Z soft switch installed

Page 50kV2 Overview



Options

• Input/Output option boards

– Sim le I/O

– Multiple I/O

• Internal Modem

- .

• Revenue Guard - 3 phase power supply

• Soft Switches – 15 function sets controlled by soft switch upgrades

Page 51kV2 Overview





Multiple I/O Option Board

• Expanded Functionality

– 2 Three-Wire Out uts

– 6 Two-Wire Outputs

– 4 Pulse Inputs (Three-Wire or Two Wire)

–

• All outputs configurable for:

– Pulse Initiator functions – Alerts, Diagnostics, & Cautions

– Load Control Operation

• Solid State rela s

– Max. ratings: 120 VAC, 0.1 AAC; 170 VDC, 0.1 ADC

• RTP and pulse inputs require 5~24 VDC, 8 mADC minimum

Page 53kV2 Overview



I/O Option Boards - Output Choices

• Pulse Initiator

– Any available cumulative measure (Wh, varh, V2h, etc.)

• Diagnostics

– Individually selectable by diagnostic type (1~8)• Cautions individuall selectable

– Low Battery (timekeeping) CA 000001

– Low Potential CA 000400

– Demand Overload CA 004000 – Received kWh CA 400000

Internal Modem

• 2400 baud design -- essentially the same as the kV

– New kV2 modem compatible with kV meters

– Old kV modem not compatible with kV2 meters

• Call Origination – Schedule, Event, Power Restoration, Power Outage (optional)

– Three phone numbers, primary & alternate defined for each call type

• Call Answer

• Shared phone line friendly – Answer window, number of rings, and call origination window

– Other phone detect circuitry

• Line sharing - up to 5 meters on one phone line

• Designed for open systems & third party integration

– Designed to meet ANSI C12.18, C12.21, and C12.19

– Supports UTS “I” command

Page 55kV2 Overview

Call in on Power Outage



Call in on Power Outage

• Optional capability to call during a power outage

– Enable with a C soft switch

• Requires additional, larger battery

• Programmable features to minimize battery use

–

– Minimum time between power outage calls

– Separate Retry Algorithm: Conserves CIO battery• Available option on Modem option board or RSX option

board (in external modem mode)

Page 56kV2 Overview

RSX O ti B d



RSX Option Board

• Jumper selectable operation

– RS-232

– RS-485

– External Modem• Enables faster communication speeds

– Up to 9600 baud communications supported

• Provides communication link to 3rd party AMR devices

– Uses ANSI C12.18 PSEM standard communication protocol• Direct “point-to-point” communication using RS-232/485

– Up to 50 feet away in RS-232 mode

– Up to 3500 feet away in RS-485 mode

• Backward Compatible – New kV2 RSX board compatible with kV meters

– Old kV RSX board not com atible with kV2 meters

Page 57kV2 Overview
