Flow Switch Circuit Test
1.
First confirm visually that the flow switch reed clamps have not been
dislodged during handling or installation.
The clamps must be fully located within their flow switch body groove
as shown.
2.
To carry out the following test you will need to a magnet.
3.
Ensure the power supply is switched on.
4.
Position the magnet directly in front of the reed clamp as shown.
If pump does not start, then slowly move the magnet up and down to a
position that exceeds the extent of the reed clamp.
The pump should instantaneously start at some point during this extent
of movement.
If this does not happen, this indicates a possible fault with the reed
switch or the P.C.B which is located within the terminal box.
These should be checked electrically. Consult Stuart Turner for further
instructions.
