VISITED SHERPUR AT INSISTENCE OF SHAHINUL ISLAM. DAMAGE REPORTED TO TELEMETRY CABINET AND PANEL. LEFT TWX OFFICE FOR SHERPUR AT 10:00 AM - 4.5 HR DRIVE. SWINGING MODULE RACK HAD BECOME UNHINGED DURING SHIPMENT OVER ROUGH ROADS. IT HAD BOUNCED AROUND ABRADING THE EXTRUDED ALUMINUM TRIM AND COVER PLATES, BENDING THE SCREWS AND TEARING THE WIRES ON THE BACK OF THE ALARM PANELS. THE RETAINING BRACKET WAS CRACKED, THE TOP BRACKET WAS LOOSE, AND THE SIDE BRAISES IN THE CABINET WERE BENT. THE CABINET WAS SCRATCHED. TWO OF THE LOGIC

12:00

RELAYS WERE DESTROYED AND THE ELCO CONNECTORS FROM THE ALARM MODULES TO THE ALARM WERE BENT AND THE CASE OF ONE WAS CRACKED. SEVERAL SCREWS WERE MISSING FROM THE TERMINAL BLOCKS.

1. REMOUNTED SWING RACK.

2. REPAIRED, REBUILT ELCO CONNECTORS, STRAIGHTENED

KEEPER SCREWS AND STRAIN RELIEF. ALL POINTS

EXHIBITED CONTINUITY ON DIGITAL MULTI METER (DMM).

3. STRIPPED, TWISTED, WIRE NUTTED AND TAPED THE

SEVERED WIRES. CONFIRMED CONTINUITY WITH DMM.

4. USED BLANK PANEL SCREWS TO REMOUNT LOOSE

TELEMETRY RACK.

5. USED EXTRA TERMINAL BLOCK (TB) SCREWS TO LAND

SEVERED WIRES.

THE TELEMETRY CABINET SITS BY A WINDOW, NO SHADE. THE METAL TOWARD THE WINDOW WAS QUITE WARM TO THE TOUCH. THERE IS ANOTHER WINDOW ON THE OPPOSITE WALL - ABOUT 6' AWAY. WITH THE WINDOWS OPEN THE CABINET IS ESSENTIALLY OUTSIDE. THE SAME IS TRUE OF THE TERMINATING CABINET FOR THE METERING EQUIPMENT.

THERE WAS NO ELECTRIC POWER AT THE SITE AND NO GENERATOR - ALSO NO RUNNING WATER, THE GUARDS WERE COOKING WITH WOOD ON THE FLOOR AND SLEEPING ON THE DESKS AND ON WOODEN PLATFORMS WITH THIN PADS. GOATS AND CATTLE WERE GRAZING IN THE PIPE FIELD. THERE WERE NO SANITARY FACILITIES.

TITAS - STILL NO CONNECTION FROM SYSTEM POWER SUPPLY SO SET UP TEMPORARY POWER SUPPLY USING 15VDC VARIABLE SUPPLY FROM TWX AND TESTED PANEL LIGHTS BY SHORTING EACH LAMP TO COMMON. MYMENSINGH #7 BURNED OUT. REPLACED WITH LAMP FROM THE "KEY" ARRAY. TEMPORARY SUPPLY NOT SUFFICIENT TO LIGHT ALL LAMPS AT ONE TIME NOR TO OPERATE FLASHERS WHEN ALL LIT. IT APPEARS THAT ONE OR MORE FLASHERS WILL NOT WORK IN THE "MASTER" POSITION. EACH ALARM FLASHED AND WENT STEADY @ ACKNOWLEDGE INDIVIDUALLY.

REMOVED EXTRANIOUS WIRES FROM T4 AND T5 ON RTU CHASSIS 1,2, AND 3.

ALL ORIGINAL MODEM BOARDS WORKING FINE. REVISED BOARDS RESPOND TO MTU, MTU HEARS BUT DOES NOT UNDERSTAND IF MORE THAN ONE IN RACK. IF REVISED BOARD IN RACK WITH ORIGINAL, MTU HEARS BOTH BUT ONLY UNDERSTANDS THE NEW BOARD.

WHEN RAI PRESENT, MTU SDI BLINKS IN CONJUNCTION WITH SDO. THIS DOES NOT APPEAR TO AFFECT OPERATION. SPARE MTU, SPARE RTU, AND ORIGINAL RTU NEED TO BE REPAIRED.

CHASSIS NOTES: SCREWS ON RTU CHASSIS 2 AND 3 ARE CORRODED. SCREWS ON THE ALARM CHASSIS AND RTU CHASSIS 1 ARE BRIGHT AND SHINEY. THE CRATE WAS OPEN AND THE PLASTIC COVER TORN TO ABOUT THE SAME HEIGHT.
