3.3.30 Removing the Load Cell PCB-Temperature Sensor-Position Sensor Assembly
The Temperature Sensor, Position Sensor and the Load Cell PCB can be removed and installed
as an assembly, as follows:
Load Cell PCB
Figure 3-114. Load Cell PCB-Temperature Sensor-Position Sensor assembly.
1. Remove the three screws that secure
the Position Sensor to the Magnet.
Lift it off, gently but firmly – to
overcome the magnetic resistance,
but avoid breaking the soldered
connections to the Load Cell PCB.
(See Figure 3-115.)
Note: Do not adjust the screws
around the Temperature Sensor hole.
It could ruin the Load Cell.
2. Remove the screw on the bottom
edge of magnet that secures the
Temperature Sensor. It has a very
fine thermister extending into the
hole between the three screws on
the bottom of the Magnet. (See
Figure 3-116.)
3. Lift out the Temperature Sensor,
careful to avoid stressing the wires
connecting it to the Load Cell PCB.
