Replacing The Heating Element - aoyue Int936A Instruction Manual

REPLACING THE HEATING ELEMENT

The heating element can be replaced as follows:
1. Follow the steps in "disassembling the soldering iron".
2. Unsolder the heating element wires (RED) and the sensor wires
(blue and/ or white).
3. The old heating element can now be detached from the hand
piece board.
4. Detach the metal protector located at the bottom part of the
heating element. (Int936 / 936 only)
5. Reattach the metal protector to the bottom part of the new
heating element. (Int936 / 936 only)
6. Pass the New heating elements wires (RED) thru the holes located
on top of the board.
7. Solder the heating element's wires and the sensor wires to the
board match with the same colored wires (red wire to red wire on
board, blue wire with blue wire on board etc.)
For Int936A / 936A:
Solder one RED wire of heating element with red wire on PCB.
◆
Solder the other RED wire of heating element with blue wire on PCB.
◆
Solder one BLUE wire of heating element with white wire on PCB.
◆
Solder the other BLUE wire of heating element with green wire on
◆
PCB
For Int936 / 936:
Solder one RED wire of heating element with red wire on PCB.
◆
Solder the other RED wire of heating element with blue wire on PCB.
◆
Solder BLUE wire of heating element with GREEN wire on PCB.
◆
Solder WHITE wire of heating element to with WHITE wire on PCB

TROUBLESHOOTING CONNECTIONS
The 5 pin socket can be tested to detect faults in the
handpiece:
Pins 4 & 2
Pins 4 & 1
Pins 5 & 1
Pins 5 & 2
Before plugging in the hand piece conduct the following test:
If any of the above mentioned combination registers a short review the
steps in "replacing the heating element" to ensure proper connections.
Warning: Ensure none of the above mentioned conditions are
present before plugging in the hand piece. Failure to do so can
damage the internal circuitry of the unit.
Test the resistances of the following configurations:
For Int936A / 936A:
Pins 1 & 2
Pins 4 & 5
Pin 3 & solder tip
For Int936 / 936:
Pins 1 & 2
Pins 4 & 5
Pin 3 & solder tip
