(5) Control circuit board (JT-30M10/JT-30M10A)
1 Disconnect the lead wires from the control circuit board.
2 Unscrew the clamping screw, and remove the control circuit board
(JT-30M10/JT-30M10A).
(One spl screw 4×12, indicated by )
Assembly precaution
Take care not to pinch the lead wires.
(6) Sensor circuit board (Middle sensor) (JT-30S2R)
1 Unscrew the clamping screws for the panel holders left (L) and right (R).
(Two PTT screws 4×16, indicated by )
2 Unscrew the clamping screws for the fix pieces.
(Two spl screws 4×12, indicated by )
3 Slightly push aside the panel holders to take out the fix pieces. (Two
locations)
4 Remove the sensor circuit boards (JT-30S2R) from the fix pieces.
Assembly precautions
• Insert the sensor circuit board between the claws
of the fix piece.
• Take care not to pinch the lead wires.
• After installing the circuit board, make sure that
the LED is upright.
(7) Power circuit board (JT-34P1H)
1 Unscrew the clamping screws, and remove the circuit board (PCB)
cover.
(Two PTT screws 4×16, indicated by )
2 Disconnect the lead wires from the power circuit board (JT-34P1H),
and remove the power circuit board.
Assembly precautions
• When attaching the PCB cover, take care not to pinch the lead
wires.
• Connect the lead wires as printed on the power circuit board.
