A2 Power Sensor Board Assembly
Repair Strategy
The recommended repair strategy for the A2 Power Sensor Board Assembly is to
completely replace it. Replacing this assembly is usually less costly than the time
it takes to troubleshoot and replace faulty components.
Procedure
When replacing the A2 Power Sensor Board Assembly, some soldering is required
in order to remove and replace the wires from connector J1. Remember that the
Power Sensor is a highly sensitive device. As such, it is affected by very small
temperature differences between its components. After performing any soldering
in the unit, wait several hours for the unit to reach thermal equilibrium before
using or testing it.
1
Use a temperature controlled 600F (311C) with a zero crossover tip.
2
Use a low temperature RMA flux SN 62 solder.
3
Do not attempt to remove flux residue from around solder joints. Using a
cleaning solution may spread the flux over the entire assembly in a thin sticky
layer.
