TROUBLESHOOTING
The red light shows that the signal is being transmitted
into the water - it should be bright. If this is not the case
check the following:
1. The ferrites should be assembled and the screws tight.
2. The mains supply should be on. Check that the PSU
is fully plugged into the mains and that the DC jack
is fully plugged into the unit.
3. If fitting to metal pipework, avoid placing unit into an
electrical loop (see below).
If the unit is fitted in a loop, move the unit to a location
outside the loop.
LOOPS
An electrical loop occurs when the signal can travel through
metal from one side of the unit to the other (I). If the unit
is fitted in a loop, the signal does not propagate correctly
and is trapped in the loop. Earth bonding or pipework is a
common cause. Loops cannot be formed if the unit is fitted
to plastic pipe.
Moving the unit to a location outside the loop – for example
“before” the earth bonding - allows the signal to propagate
correctly (J). To remove the unit from the pipe, re-insert the
split pin.
A quick test to see if the unit is in a loop is to remove
the unit from the pipe, reassemble it off the pipe,
and see if the light becomes brighter.
