CAUTION: DISCONNECT LS200 FROM POWER SOURCE BEFORE SERVICING.
F TRANSFORMER ASSEMBLY R & R.
NOTE: TO CHECK FOR DEFECTIVE TRANSFORMER, MEASURE:input (120V) 60HZ
AND OUTPUT (12.6 VAC,+/-.2 VAC @5 Amps.) SEE DWG# 441048. LOW
OUTPUT INDICATES A DEFECTIVE TRANSFORMER. HOWEVER, EVEN A
GOOD TRANSFORMER WILL PRODUCE LOW OUTPUT IF INPUT VOLTAGE
IS BELOW REQUIREMENTS. MEASURE BOTH. LIGHT INTENSITY IS
PROPORTIONAL TO CURRENT PASSING THROUGH THE LAMP FILAMENT.
F 1. REMOVE BACK HOUSING.
DISCONNECT LS200 FROM MAINS. REMOVE TRANSFORMER ASSEMBLY
FROM POLE OF MOBILE STAND IF SO EQUIPPED. REMOVE FOUR
SCREWS AND REMOVE BACK HOUSING.
F 2. REMOVE OLD TRANSFORMER.
DISCONNECT FIVE (5) TRANSFORMER WIRES FROM POWER
CONNECTOR AND SECONDARY CABLE (GRAY CORD). REMOVE
TRANSFORMER STRAPS BY UNSCREWING FOUR PHILLIPS HEAD
SCREWS. LIFT TRANSFORMER OUT OF FRONT HOUSING.
F 3. INSTALL REPLACEMENT TRANSFORMER.
ALIGN TRANSFORMER (WITH WIRES “DOWN”) WITH THREE (3)
PRIMARY WIRES TOWARDS THE POWER CONNECTOR. THESE WIRES
MUST PASS BETWEEN THE RIBS OF THE TRANSFORMER SUPPORT.
ALIGN STRAPS SO THAT HOLES IN STRAPS MATCH WITH HOLES IN
TRANSFORMER. SECURE THE TRANSFORMER WITH TWO STRAPS AS
SHOWN ON ASSEMBLY DRAWING #441019, AND FOUR STRAP-
HOLDING SCREWS. TIGHTEN SCREWS.
F 4. RESTORE ELECTRICAL CONNECTIONS.
CONNECT SPADE CONNECTORS OF TRANSFORMER ‘PRIMARY’ WIRES
TO TERMINALS OF POWER CONNECTOR AS SHOWN IN ASSEMBLY
DRAWING. BUNDLE THE THREE LINE SIDE WIRES TOGETHER WITH
A WIRE TIE. CONNECT SECONDARY TRANSFORMER WIRES TO CABLE.
F 5. ATTACH BACK HOUSING OF POWER SOURCE.
MAKE SURE THE STRAIN RELIEF AND IEC CONNECTOR ARE IN
PLACE. PLACE THE COVER ONTO THE POWER SUPPLY HOUSING
BEING CAREFUL NOT TO PINCH WIRES BETWEEN THE CASES.
FASTEN WITH FOUR (4) SCREWS.
F 6. TEST TO VERIFY SAFE OPERATION.
CONNECT LS200 TO POWER SOURCE AND VERIFY THAT ALL THREE
LAMPS ARE LIT. CONDUCT HI-POT TEST PER A-02861.
