Your
tray agitation system is warranted for three years and it is designed to
give you many
years
of trouble free service.
The
Edwards Tray Agitation System or tray rocker consists of three assemblies.
The
Rocker
Platform has three sections, which support your clearing bath trays.
The Control
Arm
assembly connects the rocker platform to the Control Unit. The Control
Unit mounts
on
a wall behind your sink.
1.
Connect the three rocker platforms with the nylon screws and thumb-nuts.
Match up
numbers
0-0 or 8-8, or how ever the sides are stamped on the sides of the tray
to the corresponding
holes.
The center tray platform should have the control arm bracket with a ball-joint
screw on the
front
edge, when youcomplete your assembly.
2.
Place the assembled platforms in your sink, at the location you plan to
use the tray
rocker
system. Control Arm bracket with ball-joint screw, should be towards
the front of your sink.
The
back edge of the platform should be a minimum of 2-1/2" to a
maximum
of 7-1/2" from the wall where the Control Unit mounts.
At
the location of the ball-joint screw, measure 23" vertically from the bottom
of your sink,
and
mark this point on the wall (this will be the top edge of the Control Unit
mounting
board).
From this mark, measure 4-1/2" straight across to the right, and draw a
2 or 3" line
straight
down (this is the location of the right edge of the Control
Unit mounting board).
3.
Place the right edge of the Control Unit mounting board on 2-3" vertical
line and the
top
edge on the 23" mark, level the unit and mark the five (5) mounting holes
with
the(special)
nail provided. Assistance may be required to hold the unit level
while the
location
are marked.
4.
For sheet rock walls, use the anchors provided by simply screwing in the
anchors until
flush,
at each mark. If a stud is encountered, remove the anchor and just
use one of the
screws
provided.
5.
It
is important that the Control Unit be firmly and securely attached to a
fixed vertical
surface.
Alll five (5) mounting locations are necessary. Failure to properly
and securely
attach
Control Unit could cause severe personal injury, if the unit were to pull
or fall from
the
wall, and splash the clearing bath acids on you.
6.
Before attaching the Control Unit to the wall, open the hinged door
on the right side of
the
unit . Attach the Control Arm at the quick-disconnect ball-joint;
a slight twisting and
pushing
force is requried. Next, screw the Control Unit to the wall with
the
Control Arm hanging down. Assistance may be required.
7.
Loosen the three (3) slotted set screws in the control arm.
Snap on the brown plastic
snap-on
ball socket on ther center tray. Note: Platform can be
easily unattached for
cleaning
sink or using sink for other purposes.
8.
Plug the unit into an electrical outlet and check the GFIC (Ground Fault
Interrupt Circuit
outlet)
before turning on the switch. Push in the red or reset button until
you feel a click
(if
it has been tripped and is sticking out slightly). Test the GFIC
weekly by pushing the
test
button and resetting with the red or reset button. If you can reset
with the red or
reset
button, then the GFIC will protect you from electrical shock when using
your tray
rocker.
9.
Push both rocker switches to the up position (white dots). The motor
should run
continuously
and there should be some movement of the control arm. Carefully open
the
side
door on the Control Unit, being careful not to put your hand or fingers
into the
unit,
to observe the position of the ball-joint screw. Jog the unit with the
left rocker switch,
until
you get the screw to stop in the horizontal position or the 3 or 9 o'clock
positions.
This
may take several attempts.
10.
Rotate the tray platform so that it is horizontal position without any
tilt, check both ball-
joints
to make certain they are not in a bind and are free to rotate, then tighten
the three
slotted
set screws in the control arm. Do not over tighten the slotted-set
screws or the
plastic
treads will strip. Just snug them up firmly, the cupped point
on the set screws will
grip
the stainless rod. Check the rocker for uniform rocking front-to-back,
and adjust the
set
screws as necessary to get an even rock. Now you are ready to rock.
General Information:
The
rocking motion of the tray platform sends a small wave over the surface
of the clearing
solutions.
As this wave travel across your print, it produces a shearing action which
pushes
the salts away from the prints surface and pulls fresh solution behind
it. This wave
is
like the smaller second wave that follows the first wave, we see along
the beach.
| Left Rocker Switch | Right Rocker Switch | ||
| Up = "On" | Up = "Continuous Rocking" | ||
| Down = "Off" | Down = "Intermittent Rocking" |
Rotating Knob thru the 12 clock dial positions
1:00 = ~2 Seconds Between Rocks
4:00 = ~15 Seconds Between Rocks
8:00 = Continuous Rocking
Most
printers seem to operate their units between settings 3-6 seconds for the
intermittent rocking
motion.
You
will have to work with the amount of solution in the tray and the timing
to get the best
results
without splashing or damaging prints. Use a set of practice prints
to set-up your
optimum
conditions.
Some
printers operate on "Continuous" for the first 2-5 minutes when they put
a new print
in
the first clearing bath, then switch to the " intermittent rocking motion".
A
lab timer can be plugged into the GFIC outlet on the left hand side of
the Control Unit.
Maximum
outlet power is 125 VAC at 5 AMPS.
Do Not block the air cooling holes along the back edge on the top of the Control Unit.
The
cam located in the Control Unit has three (3) positions to control the
length of stroke,
but
your unit has been set for your tray size, and should not require
changing. If it is
necessary
to adjust the length of stroke, unplug the "Control Unit" from the power
source
before opening the right side access door, and remove the quick-disconnect
ball-joint.
To change the position the ball screw, you must hold the cam body with
channel
lock
pliers, while rotating the ball screw CCW (to remove) with a small wrench.
Grasp the
ball
screw firmly as the treads are coated with vibration resistant compound.
If you have
large
fingers and/or hands, you may have to remove the Control Unit from the
wall,
because
of the limited space.
Larger
trays will require the longer stroke. Setting a longer stroke with
small (8X10) trays,
produces
too much agitation and shorter stroke with larger trays will not produce
the
traveling
wave.
If
you want to start processing larger prints, you do not need to buy a new
unit.
You simply buy new rocker platforms for your new tray size. You can
contact
me for a quote.
Keep
the lower snap-on ball joint screw coated with silicone grease, as this
part is not
stainless
steel and it tends to rust slightly. This part is not available in
stainless steel, but
when
it I find a source I will send you one at no charge.
With
the repeated rocking motion, the tray platform will tend to "walk" or rotate
slightly
about the control arm pivot point . Most people do not notice this
phenomenon,
since
the sink walls keeps it in check it. Some printers put a graduated
cylinder or short
piece
of PVC pipe at the top or bottom edge of the tray platform, to keep it
in check.
Contact
me at 512-267-4274 if you have any questions or you have problems with
your
process trays fitting the rocker platform properly. The best time
to catch me
is
after 7:00 p.m. CST..
Keep
on Rocking.....Happy Printing......Enjoy. You will wonder how you
ever got
along
without it!!!
