Ransburg RCS 2 Ratio Control System - Manual (Page 50)

Once the operator responds to the above prompts,
a screen similar to the following appears:
This chart displays a simple 6 step sequencer
where the user defines how long they wish each
step to take and which valves or signals should
be energized at each one of those steps. There
are 6 steps for the flush cycle and 6 steps for the
fill cycle. When a color change is desired, the
sequencer automatically runs the flush sequence
followed by the load sequence.
The following solenoid valves can be controlled
by the sequencer:
Resin/Solvent Air Chop
Resin Solvent
Resin Air
Paint
Resin Pump Bypass
Resin Pump Flush
Trigger Solenoid
Resin Override
Dump Valve
Catalyst Select Valve
Catalyst Solvent
Catalyst Override
The following RCS-2 inputs can be controlled by
the sequencer:
RCS-2 Run
RCS-2 Halt
RCS-2 Fast Fill
RCS-2 A Fill
RCS-2 B Fill
RCS-2 Trigger
Note that there are too many valves and signals
to be displayed on one screen. Therefore, the
operator must scroll down to see the bottom five
items.
There are 8 function buttons defined while editing
flush, load, and color change sequences:
F1: Modify - This button brings up a numeric
keypad if cursor is on one of the step duration
cells. If cursor is on one of the valve condition
cells, that cell is toggled from off to on or on to off.
F2: Air Chop Time - This button allows the user
to program how long the air valve remains on for
each step of the solvent/air chop timer.
F3: Solvent Chop Time - This button allows the
user to program how long the solvent valve re-
mains on for each step of the solvent/air chop timer.
F4: Edit Flush or Fill - This button opens the
screen that allows viewing and editing of the
sequences. (If the flush screen is displayed, it
switches to fill, or vice-versa.)
F5: Send to Opto22 - This button allows the op-
erator to immediately send the edited sequence
to the sequencer (located in the motor amplifier
panel). Note that the sequences are automati-
cally sent to the sequencer every time a new Job
Number is loaded.
F9: Read In File - This button allows the operator
to load flush and load sequences from a diskette.
Note that all sequences for all guns and all jobs
are overwitten on the flash drive, using the data
on the diskette.
