If
you are having trouble with your SpeedCoach Gold please check the following potential trouble spots:
|
IMPELLER
- should
go 16'3" from the bow. If elsewhere on the boat, the
SpeedCoach Gold should be recalibrated.
- should
be approximately under footstretchers
- need
not be on the centerline, but must be submerged (if
NOT centered be sure to align the sensor accordingly)
- can
be adhered with double-sided tape (included) or good
electrical tape
|
| SPEEDSENSOR (BLUE SENSOR)
- should
be as close to the impeller as possible (maximum or 11")
- must
be on opposite site of the hull from impeller
- can
be perpendicular to impeller directly above impeller, or
be parallel to impeller one impeller length in front or behind
impeller
- must
be fixed securely to shell (NOT loose)
- clean
surface well before taping to boat
|
|
| SEAT SWITCH (BLACK SENSOR)
- should
be mid-way through the slide length
- must
be oriented perpendicularly to the axis of the boat
|
|
| MAGNET
- should
be between 3/4" and
1 1/2" from the
deck
- must
be oriented perpendicularly
to the axis of
the boat
|
|
| CALIBRATION
- The
SpeedCoach
Gold
is
factory
calibrated
to
provide
reasonably
accurate
performance
in
most
shells
with
the
impeller
installed
approximately
16'
3" (5
m.)
from
the
bow.
Calibration
is
an
optional
step
which
allows
the
display
unit
to
compensate
for
different
impeller
locations
and
to
perform
very
accurately.
You
do
not
need
to
calibrate
your
system
if
you
are
concerned
only
with
comparing
performance
from
day
to
day.
To
calibrate
your
system,
row
or
paddle
over
a
measure
distance
on
still
water
(on
moving
water
row
or
paddle
both
up
and
down
stream
and
average
the
results
shown
on
your
display).
Then,
use
the
following
formula
to
obtain
your
calibration
value:
|
|
- Make
a
record
of
your
claibration
value
for
future
reference.
If
you
move
your
unit
to
a
new
boat,
or
modify
the
location
of
your
impeller,
you
may
want
to
recalibrate
it.
- Please
note:
Calibration
is
boat
and
location-specific.
If
you
move
your
unit
to
a
new
boat,
or
modify
the
location
of
your
impeller,
you
may
want
to
recalibrate.

TROUBLESHOOTING THE SPEEDCOACH GOLD
Always try to borrow a fellow rower’s SpeedCoach or SpeedCoach Gold so that you can narrow down the variables. By testing your boat’s docking station with a functional unit, and having your unit tested in a functional docking station, you can help determine where the problem exists. Make sure that the SpeedCoach Gold you are using has a calibration of 1.000 and is set in 2-Stroke Mode.
Initial Checklist
If a functional unit will not work in your boat, then the problem most likely exists with your wiring and/or docking station...
- Check to make sure there are no cuts, nicks or pinched areas along the wire. (a flashlight will be helpful here.)
- Be sure that both sensors are aligned correctly (see Installation).
- Be sure that there is no debris or corrosion on the impeller.
- Check that the metal contacts on the mounting dock are flush with the surface of the dock, (contacts may be cleaned with a non abrasive cleanser, like Bon-Ami, to ensure true surface). DO NOT use solvents on the docking station as it may cause damage and voids the warranty.
Problem 1: Speed or Pace Readings are Inaccurate
- TroubleShoot 1: Is the Calibration Value Set Correctly? The calibration value should be set at 1.000 unless you have completed the necessary steps to re-calibrate your unit.To check and/or reset your calibration value, see “Calibration” on page 12.
- TroubleShoot 2: Is the Impeller Properly Installed? The impeller is to be placed 5 meters from the bow of the boat (see “Installation”on page 11). If for any reason you cannot place the impeller in the proper location, the unit will provide incorrect information unless recalibrated.
- TroubleShoot 3: Does the Impeller Spin Freely? If the impeller begins to accumulate any debris or slight corrosion, it may not spin freely which will lead to inaccuracy. If you are unable to clear the debris, a new impeller can be purchased. If impeller is still covered by the 1-year warranty, the customer can return the faulty impeller for a replacement.The impeller may be unscrewed and replaced without removing the hull mount. Note:Any slight hum created by the impeller should fade within a week or so.
Problem 2: No Stroke Rate or Rate Seems Incorrect
- TroubleShoot 1: Is Unit Making Contact with Bracket? The unit must have clear contact with contact pins on mounting bracket. Push unit into mounting bracket until “click” is heard. Be sure lanyard is not interfering with the connection.
- TroubleShoot 2: Is the Magnet and Sensor Aligned? Double check the set-up and orientation of the seat magnet and black sensor (see page 10 ).
- TroubleShoot 3: If Rate Seems High, Check Stroke Mode. If your stroke rate consistently seems very high, almost double what it should be, the unit may be in single stroke mode (1-Str).Make sure unit is set in 2 stroke mode (2-Str).
- TroubleShoot 4: Is the Unit in Memory Recall Mode? If there is no rate, time or distance displaying make sure the unit is not in Memory Recall mode. If so, hold down the top button for 2 seconds to exit. If the timer is only displaying rate and split, but no time, distance or stroke count, the unit is in STOP mode. Press the top button once to exit STOP mode.
