M‑7600 Series Protection and Control System Applications

The M‑2032B in conjunction with the M‑7600 Series includes smart battery charging

features that are a result of the Beckwith Electric proprietary communication protocols

employed between the M‑2032B and M‑7600 Series utilizing a SATA cable connected

via the Aux I/O port on the M‑7600 Series. The following features are provided when

a M‑2032B is connected to a M‑7600 Series:

• Receives commands to:– Turn‑on/off battery test load– Turn‑on/off 13.8 Vdc

accessory supply– Turn battery supply off 

• Communicates the following to the M‑7600 Series:

– Charger state

– Main power supply status

– Battery Voltage

– Battery Current

– Recloser Gas Pressure (if recloser is equipped with sensor)

• Includes a Wakeup system that is initiated by the local panel pushbutton.

Turn-on/off Battery Load Test Command

M‑2032B Battery Charger/Power Supply – Specification

The M‑7600 Series issues the “Turn‑on/off Battery Load Test” command to the

M‑2032B to test the battery capacity when the unit is operating from the main

power supply.

Turn-on/off 13.8 Vdc Accessory Supply (Aux Power)

The accessory supply provides power for external devices such as radio,

modems, etc. When the M‑2032B is used in conjunction with the M‑7600

Series, the 13.8 Vdc output can be enabled/disabled utilizing the control’s

HMI, IPScom, or communication protocols.

Turn Battery Supply Off Command

When the battery voltage decreases to less than a level set by the user, the

battery supply to the M‑7600 Series will be turned off (Sleep Mode) to protect

the battery. Discharging batteries below certain levels will shorten the life of

or damage the battery.

Wakeup System Command

The Wakeup system command is initiated by the M‑2032B local panel pushbutton.

The wakeup system command allows the user to wake the M‑7600 Series from

the Sleep Mode that was initiated by the Battery Supply Off command.

The wakeup system command restores power to the unit for a user defined time

period. If the main source power is not restored, then the Turn Battery Supply

Off command will be reinstated placing the M‑7600 Series in Sleep Mode.

Introduction

The M‑2032B Battery Charger/Power Supply provides 24 Vdc output to power

the low voltage configured M‑7600 series of Beckwith Electric Protection and

Control Systems. Also provided is a 13.8 Vdc output which can be used to

power radios or other auxiliary equipment.

In addition to providing output power, the M‑2032B is capable of charging 24

Vdc batteries when main power is supplied. Included is circuitry to detect a

loss of main power and automatically provide backup power from the 24 Vdc

batteries ensuring operation is not interrupted.

Battery Charger Monitoring System

The Battery Charger Monitoring System must be enabled in the Setpoints/Common

Setpoints/PSBC/IED Power Supply/Battery Charger Monitor dialog screen (Figure 1).

Also included in the Battery Charger section are the settings for:

• Minimum battery voltage to turn OFF IED

• Enable/Disable and set time to perform Load Test

• Power Off Delay After AC Loss

• Power Off Delay After Wakeup

• Enable/Disable 13.8 Vdc Accessory Supply (Aux Power)

• Provides 24 Vdc power to any Beckwith Electric M-7600 Series

Protection System or Control configured with Low Voltage power supply

• Provides 13.8 Vdc Accessory power

• Accepts AC or DC power input from 105 to 285 Vac (50/60 Hz) or 120

to 285 Vdc

• Charges a 24 Vdc battery system which upon AC power interruption

can be used as temporary power (UPS) supply

• Transient protected

• Substation hardened -40° C to +85° C

• Conformal coated

Stand Alone Applications

In a stand alone application the M‑2032B is designed to provide the following

features:
