Calibration Overview:
calibration teaches the Processor the
unique plumbing and flow characteristics of each connected
device, and enables SSA to distinguish between normal and
below normal flow over the full range of operating conditions.
Air conditioners, generators, circulator pumps, refrigeration
pumps, and r/o systems operate at a constant speed, so one
calibration flow rate is required. Propulsion engines operate at
variable speed, determined by throttle setting, so calibration is
required at multiple throttle settings.
calibration takes place at the helm (or at any location if multiple
stations are installed) and can be conducted by one person, but
we suggest calibrating with two persons - one to operate the
vessel and one to perform the calibration.
the touchpad has two buttons – an “acknowledge” (bell) button
and a hidden button located next to the bell button. lightly
pass your finger over the hidden button location to detect a
slight bump. both buttons will be used during calibration.
You may calibrate constant speed devices (generators, air
conditioners and pumps) while at berth, but engines must be
calibrated in open water where full throttle operation is safe.
calibration notes:
*before calibrating any device check these maintenance items
that will affect flow rate:
-the raw water strainer filter basket is clean
-Pumps impellers have no broken or missing blades
-the seacock is fully open and clear
-Plumbing connections are tight and free of leaks
-there are no hose kinks
*calibration mode will automatically end if no buttons are
pressed for five minutes. You will not lose calibrations already
successfully completed.
*if a calibration attempt is not successful you will hear 2 short
beeps and the corresponding leD will return to a solid light.
refer to the troubleshooting Section.
to cAlibrAte conStAnt SPeeD DeviceS:
1. turn on the pump, air conditioner or generator and observe
that raw water flow is present.
2. to enter calibration mode – press and hold both buttons for
3 seconds. All leDs will flash 3 times to confirm calibration
Mode. release both buttons. A solid leD identifies which
device is offered for calibration. if this is not the device you
want to calibrate press the hidden button to advance to other
devices. When the device you want to calibrate is indicated by
a solid leD press the bell button to accept this device; the leD
will flash at a one second interval.
3. to calibrate the device - press the bell button. rapid beeping
indicates that the Processor is collecting data. When data
collection is complete the leD will automatically advance to
the next device.
4. When the device you want to calibrate is indicated by a solid
leD press the bell button to accept this device; the leD will
flash at a one second interval.
5. repeat step 3 for each constant speed device.
6. to exit calibration mode - press and hold both buttons for
3 seconds. All leDs will blink three times, the horn will beep
simultaneously, and the leD’s will cycle to indicate that the
calibration mode has been exited.
to cAlibrAte enGineS:
engine calibration note: engines with 3/4" to 1-1/2" plumbing
will collect flow data quickly (in about 2 seconds). engines with
2" and larger plumbing may take up to 10 seconds to collect flow
data.
the data collection process is indicated by rapid beeping. Do not
change throttle setting or make touchpad selections during data
collection.
1. run the engine(s) at idle speed and confirm that water flow is
present. Proceed to open water (you will have to operate at
idle speed and at full throttle to complete the calibration
process for each engine).
2. to enter calibration mode - press and hold both buttons. All
leDs will flash 3 times to confirm calibration Mode. release
both buttons. A solid leD identifies which device is offered
for calibration. if this is not the engine you want to calibrate,
press the hidden button to advance to the next engine. Press
the bell button to accept the engine for calibration.
3. to calibrate this engine at idle speed - press the bell button
again; rapid beeping indicates the collection of flow data.
When beeping stops, idle speed data collection is complete.
4. the leD flashing rate will increase – accelerate to full throttle
When SAFe to Do So. After the vessel has reached plane
and is running at stable speed wait 15-seconds to allow raw
water flow to stabilize.
5. to calibrate this engine at full throttle press the bell button –
rapid beeping indicates the collection of flow data. When
beeping stops, data collection at full throttle for this engine is
complete; the leD will automatically advance to the next
device.
6. repeat steps 3, 4 and 5 for each engine.
7. to exit calibration mode - press and hold both buttons. All
leDs will blink three times, the horn will beep simultaneously,
and the leD’s will cycle to indicate that the calibration mode
has been exited.
