amount (2% elongation or greater). The
wave may also be somewhat choppy because
of the low system volume. If the outputs were
originally only slightly lower or higher than
the inputs, the problem is likely not a leak
but calibration. Call Flexcell
®
for further
instructions. If the output max % elongation
increases significantly when the quick
disconnects are connected together, the leak
is most likely in the baseplate or gaskets.
Solution 1:
Remove gaskets and plates from
baseplate. Check to see that each gasket is
firmly seated in each plate without any folds
in the thin bottom lip of the gasket and with
each inside corner butted up against each
outside corner of the BioFlex
®
plate. Place
each plate and gasket carefully into each
baseplate well. Check to be sure that the
gaskets are flatly seated in the wells; i.e., none
of the sides touching the baseplate to the point
that the gasket is not able to fully enter the
well. Move each gasket forward and back and
side to side within the well to be sure that they
are somewhat loose in the plane of the
baseplate. This will allow the vacuum
pressure to pull the gaskets and plates firmly
down to seal flat against the baseplate surface.
Run a regimen. The plates and gaskets may
require some initial hand pressure to start the
seal. Place the Plexiglas cover and a couple of
lead weights (approx. 10 lbs total; variable) on
top of the plates. If there is still a noticeable
leak, check all sides of each BioFlex
®
plate to
see if the membrane is protruding from any
side. If there is any noticeable membrane
protrusion, remove this with a razor blade.
Problem 2: Regimen wave is flatlining
Solution 2:
Remove the
SYSTEM
vacuum line at the
back of the FlexLink
®
and check to be sure
that there is vacuum coming through the line.
Check the
VENT
port at the back of the
FlexLink
®
when the system is running to see
if air is moving in or out. If not, it is possible
that the valves are locked due to residue
buildup. Try applying positive pressure to
the
VENT
port to free the valves.
If the regimen wave is flatlining but the
plates are still cycling air pressure, try the
following:
Disconnect the blue 1/4" (6.4mm)
FLEX IN
tubing from the back of the unit and place a
finger over the end of the tubing while a
regimen is running. If air is cycling at the
end of the tubing then the problem is with
the FX5K
™
Tension FlexLink
®
. Contact
Flexcell
®
International for further
instructions.
Problem 3: Regimen wave is fluttering or
not smooth
Solution 3:
This problem could be due to water in
the valves or the system being out of
calibration. Run the drying regimen with the
drying filter (as described in the manual) to
dry the system and valves. If this does not
resolve the problem try running the drying
regimen once more. If the problem
continues, contact Flexcell
®
for further
instructions.
Problem 4: Programming a long regimen
(1 day or more) but the software will not
allow the regimen to be saved.
Solution 4:
The software has a limit on the number
of cycles that can be entered into any given
step (65,535). If a regimen is programmed
with a step that requires more than 65,535
cycles, the software will give an "invalid
entry" error. To run the regimen for the time
required additional steps will need to be
programmed. This will not create any breaks
in the regimen. Simply divide the total time
in half (or as many times as is necessary) and
make additional steps with the same
parameters. See section 3.5 of the manual for
