OPERATING
GUIDE
Liquid level in the pump priming chamber is
monitored by the
SONIC START ® resonant
frequency liquid level prime sensing probe
with piezoelectric drive and sensitive circuits
to detect frequency shifts when the
SONIC
START
®
Prime Sensing Probe is covered by
liquid. If water covers the Sonic Start
®
Prime
Sensing Probe, it changes the natural frequency
and the Sonic Start
®
Relay, located inside of the
SONIC START ®
Prime Sensing Probe changes
state.

Indicating Lights
There are two (2) indicating lights in the
translucent plastic portion of the SONIC START
®
Prime Sensing Probe. One light is
Green and
one light is Red .
Power Indicating Light
A steady
Green light indicates the SONIC
START ®
Prime Sensing Probe is receiving
power and can operate. The
Green
light will be
lit whenever the 120 VAC power for the pump
station or PISTA ®
Grit Chamber is turned on.
Primed Indicating Light
The Red
light will be lit continuously when the
pump is not primed. The Red
light will turn off
when the pump is primed.
Electrical Problems Indicating Light
A flashing
Red light means that there is an
overload or short circuit in the SONIC START
®
wiring or a problem with the
SONIC START ®
Prime Sensing Probe. See the Troubleshooting
Section of this manual to determine the problem.
Simulate The Priming Process
The SONIC START ®
comes with a means to
test the SONIC START
®
Prime Sensing Probe.
This is done by changing the state of the relay
located inside of the SONIC START
®
Prime
Sensing Probe. Each
SONIC START
®
comes
with a magnet that can be used to change the
state of the relay located inside of the SONIC
START ®
Prime Sensing Probe. This allows
the operator to simulate either a primed or not
primed operation. This is important for both
testing and troubleshooting the
Sonic Start ® .
To simulate the priming process, first note which
state the SONIC START ®
is in:

Primed State
(Green Light On,
Red Light Off)
or

Not Primed State
(Green Light
On, Red Light On).
Hold the magnet up against the target symbol
on the SONIC START ®
Prime Sensing Probe
for a few seconds to change the state of the
relay located inside the SONIC START ®
Prime
Sensing Probe. If the
Red indicating light
changes state, the SONIC START
®
Prime
Sensing Probe is operating correctly.
