Ransburg RCS 2 Ratio Control System - Manual (Page 66)

Horn – In the top center of the panel is a horn that
indicates when the RCS-2 controller has turned
on the “Spray Shutdown” output for the gun.
Total Flow – This is an LCD display that indicates
the current flow rate out of the applicator (or appli-
cators, if multiple applicators are fed from one fluid
panel). It operates from an analog output signal
from the RCS-2 controller with 0 VDC being 0
cc’s/min and 10 VDC scaled to be 2000 cc’s/min.
Flow Control – This is a potentiometer that varies
the analog flow control voltage into the RCS-2
channel card from 0 volts DC to 10 volts DC.
Users can program what flow rate they want for
both extremes by using the Min. Flow and Max.
Flow parameters under the edit gun screen.
Faulted/Fault Reset – This is a red illuminated
pushbutton. The lamp will be illuminated any time a
fault occurs in the RCS-2, whether that fault causes
a spray shutdown condition or not. Pushing this
button resets any fault that has caused a spray
shutdown condition. It does not reset a non-fatal
fault (one that is disabled in the “Config. Alarms”
setup screen of the RCS-2). After resetting a fa-
tal fault, the user must then push the Ready/Run
pushbutton to put the gun back into run mode to
resume spraying. Note that this lamp will flicker
when the controller is folding back the outbound
pressure of the pumps.
Ready/Run – This is a green illuminated pushbut-
ton. Pushing this button puts a gun into run mode.
When in run mode, the green lamp is illuminated.
It is extinguished in ready, halted, or faulted state.
Guns in Flush Box – These are two LED’s that
indicate when up to two sprayguns are in their
respective flush boxes. A flush or load sequence
will not be allow to start until both of these indica-
tors are illuminated. These LED’s are connected
to four pressure switches, which are actuated by
the two flush boxes. (One indicates that the gun
is in the box and the other indicates that the flush
box is closed.) The signal from these pressure
switches also feeds the Paint Fill and Purge
pushbuttons to prevent color changes and purges
from occurring unless the guns are in their flush
boxes and the boxes are closed. These pressure
switches should be jumpered if gun flush boxes
are not to be used. There are jumpers on the PC
board inside the panel to bypass these pressure
switches.
Feather Reset – This is a simple pushbutton that
sends a Feather Reset signal back to the RCS-2
control console.
Spray Test – This is a simple pushbutton that
sends a trigger signal back to the RCS-2 channel
card and also turns on the trigger solenoid to allow
operators to verify and test flow, etc. (A valid color
must be loaded for this button to work.)
Jumpers – In the lower right corner of the PC board
inside the panel there are four jumpers labeled:
JMP1, JMP2, JMP3, and JMP4. If a single gun
flush box is being used, remove the jumper at
position JMP1. If two gun flush boxes are being
used, remove jumpers JMP1 and JMP2. JMP3
and JMP4 should always remain installed.
