change the state of the relay located
inside the
SONIC START
®
Prime
Sensing Probe.
If the Red indicating light changes
state and turns on, the
SONIC
START
®
Prime Sensing Probe is
operating correctly. Go to
Step 3
.
If the Red light did not light up after
holding the magnet to the
SONIC
START
®
Prime Sensing Probe,
the
SONIC START
®
Prime Sensing
Probe needs to be replaced.
3.
Check the wiring to the control panel
and back. If, after checking all of
these wiring items and it does not
correct the
Red
light, then check
the
Din Connector Cable (Item 9).
Make sure the
Din Connector Cable
(Item 9)
is securely screwed in and
attached to the
SONIC START
®
Prime Sensing Probe. If the
Red
light
turns on, this was the problem and
the pump will operate normally now.
If not, go to
Step 4.
4. If the
Red
light still does not come
on, switch the
SONIC START
®
Operating
Module out with
another
SONIC START
®
Operating
Module. If this resolves the problem,
you have a defective
SONIC START
®
Operating Module and after you
replace it, the pump will operate
normally. If not, go to Step 5.
5. If this still does not solve the problem,
then switch out the
SONIC START
®
Prim Sensing Probe itself. The
Troubleshooting 3
If the pump runs, but it is not primed and the
Green
indicating light is
On
and the
Red
indicating light is
Off
, follow the steps below
until the pump will prime.
1. If the
Green
indicating light on the
SONIC START
®
Prime Sensing
Probe is lit and the
Red
light is not
lit, clean the
SONIC START
®
Prime
Sensing Probe. You can either access
the probe in two ways:
• by removing the Dome Assembly
and using a soft bristle tooth brush to
gently wipe the probe clean, or
• by unthreading the
SONIC START
®
Prime Sensing Probe from the motor
adapter and wipe it clean with a soft
paper towel.
After cleaning the
SONIC START
®
Prime Sensing Probe, reinstall it or
the dome. If the
Red
light turns on,
this was the problem and the pump
will operate normally now.
2. If the Green indicating light on the
SONIC START
®
Prime Sensing
Probe is lit and the Red light is still
not lit after cleaning the probe, test
the
SONIC START
®
Prime Sensing
Probe by changing the state of the
relay located inside of the
SONIC
START
®
Prime Sensing Probe. Hold
the magnet up against the target
symbol on the
SONIC START
®
Prime
Sensing Probe for a few seconds to
