3. DC or AC Fail Annunciation and/or all ‘Optional Features’, including ‘Serial Communication Interface [SCI]’.

• Lamp & Alarm TEST [LAT]    {Instead of ‘Lamp TEST’ [LT]}

No Extra Price for this Optional Feature

• Lamps [LEDs] on all Windows glow STEADY [ON] & Audible Alarms [Bell/Hooter/Buzzer] remains in ON mode, as long as Lamp & Alarm TEST [LAT] Push Button is kept pressed.
• User’s choice of “LAT” instead of ‘default’ “LT” [Lamp TEST], does not attract any Extra Price, however this feature is provided only when specified in ‘Ordering Information’.

• DC or AC Supply Fail Annunciation

Extra Price chargeable for providing this Optional Feature

Annunciator Unit is capable of working on ‘Universal’ Voltages [either DC or AC], since it is powered by ‘Switched-Mode Power Supply’ [SMPS]. Using this capability, we offer : ‘DC or AC Supply Fail Annunciation’
Principle of Operation :      [Vise-versa, for AC-operated Annunciator]

• When ‘Normal’ DC Voltage fails in a DC-operated Annunciator, ‘Stand-by’ AC Voltage is applied to Annunciator using ‘DC Fail’ ‘Changeover’ Circuitry [Kit]  … and …
• ‘DC Fail’ Buzzer is sounded using ONE pair of ‘Special’ ‘NO’ Contact [provided on Annunciator Unit].   

• “Internal” C/O Kit : ‘DC Fail’ sensing & ‘Changeover’ Circuitry provided ‘inside’ Annunciator.

Important NOTE on : DC or AC Fail Annunciation & C/O Kit

• ONE pair of ‘Special’ ‘NO’ Contact shall be provided on Annunciator only when DC or AC Fail Annunciation is Ordered as an ‘Optional Feature’.   [Ref : Ordering Information]
• Unless otherwise specified, DC or AC Fail Annunciation shall be displayed on 1st Window ONLY [Industry Standard].
• We recommend “Internal” C/O Kit since DC or AC Fail Annunciation shall be ‘Factory-Tested’, for proper functioning.

‘DC Fail’ Annunciation with ‘External’ C/O Kit  [Ref : Fig. 1] :   {Vise-versa, for ‘AC Fail’ Annunciation}

• Terminals of “External” ‘C/O Kit’, including ‘initiate’ Terminals of ‘nth’ Window {chosen to display ‘DC Fail’} shall be Wired to Annunciator Terminals, as in Fig. 1.
• Wire 'DC Fail' Buzzer to 'Special' ‘NO’ Contact on Annunciator & connect same to 'Stand-by' Supply.
• ‘Select’ ‘nth’ Window to “NonTrip” Alarm, for driving 'DC Fail' Hooter [Wired to 'Special' Contact].
• During 'DC Fail', ‘Stand-by’ Supply [via SMPS], activates not only the ‘nth’ Window, but also all Windows of Annunciator. Hence entire Annunciator functions normally on ‘Stand-by’ Supply.

1. Serial Communication Interface.

Extra Price chargeable for providing this Optional Feature

Serial Communication Interface available in following Protocols :

General Details of : ‘Bharani’ Default Protocols

Protocol 1 : MODBUS ~ in RTU/ASCII formats, through RS 485 Port, being ‘Industry Standard’, provides Serial Interface with ‘Master’ [Local Personal Computer [PC], SCADA, PLCs, etc...]

1. Description of MODBUS Serial Communication Protocol in RTU Mode for ‘Function 02’

‘Function 02’ reads Fault Status of Field Inputs [Field Contacts] to Annunciator Unit.
Logic 0 = No Fault & Logic 1 = Fault Occurred. ‘Master’ [PC or SCADA System] sends a query to Annunciator Unit [‘Slave’] to obtain the Status of Field Inputs [connected to Annunciator Unit].

1. Facilities provided to User, on Annunciator Unit :
2. ONE No. “2 Way Terminal Block” provided, to enable User to connect RS 485 Cable to Master.
3. TWO Nos. “8 Way DIP Switches” are provided, for the following :

DIP Switch 1 : For User to ‘Select & Set’ Baud Rate of Data transfer from Slave Annunciator to Master.
DIP Switch 2 : For User to ‘Select & Set’ Address of Slave Annunciator Unit.

1. Default Value for Baud Rate = 9600 & Default Value for Slave Address = 01

Protocol 2 : SPP [Standard Proprietary Protocol] ~ ‘Bharani’ – Customised Protocol, through RS 232 or RS 485 Port

1. For PC-side processing of Serial Data logged-on, a Compact Disc [CD] containing our customised Application Software is supplied along with the Annunciator Unit, to enable the User to load the Software on to the PC.
2. This Software shall be factory-loaded to display on the PC Monitor, the following [Password protected] :
3. Window Configuration [Windows per ROW  x Windows per COLOUMN] of the actual Annunciator Unit.
4. Legend on Windows [as on the Annunciator Unit]. [NOTE : “Edit’ facility provided, to alter the Legends]
5. Working Sequence of Operation [as ‘Selected’ in the Annunciator Unit].
6. Segregation of Windows [displaying different Coloured Windows] for Trip & NonTrip Audible Alarms.
7. Real Time & Date [as in PC]
8. When Serial Communication Port is connected to PC, Alarm Annunciator establishes continuous logging of status of all Windows. ‘Fault-status’ on all Windows ~ “Flashing, Steady & Off” states are displayed on the PC Monitor, similar/ identical to that in the actual Annunciator Unit.
9. Time-wise & Date-wise Data for ONE Week, of ‘Fault-status’ on all Windows, are stored in an exclusive File on PC.
