to a dry contact relay with allowable current limited
to 1 amp 45 volts, AC or DC (exceeding this limit
may damage the output on the channel card).
Although a myriad of voltages could be used, it
is recommended that the Hi signal be connected
to the +24 VDC terminal (terminal #1331) and the
output be taken from the Lo output terminal. This
terminal will supply 24 VDC when the output is
energized by the software. (Referenced ground
terminal is #1113.)
An alternate way of connecting these outputs
would be to connect the positive supply voltage to
the load, the common of the load to the Hi output
terminal of the RCS-2 output, and connect the Lo
output terminal to both the ground of the supply
connected to the load and the ground terminal
(terminal #1113). Once again, current must be
limited to 1 amp and should never exceed 40 volts.
Volume Fill
Type of input: Gun
Type of signal: Pulsed
By pulsing the volume fill discrete input, the unit
will be put into the V. FILL mode. (The gun must
be in the ready state prior to this.) When the
gun trigger input goes high, the pumps will run
at the programmed flow rate and ratio until the
volume programmed in for Fill Volume (on the
Job parameters screen) is dispensed. If more
than one gun trigger inputs goes high (triggers 2,
3, or 4) the unit will multiply the flow rate by the
number of high inputs but still only run until the
programmed volume is dispensed. When that
volume is reached, the gun will be halted and
returned to the ready state.
Volume Fill with Fast Fill Mode
It is possible to volume fill and fast fill simultane-
ously. If the gun is put into volume fill mode, and
then the fast fill input is pulsed, the unit will run in
fast fill mode until the volume programmed in for
fill volume is dispensed. At that time, the gun will
be halted and returned to the ready state. This
happens regardless of the condition of the gun
trigger inputs.
Push Out
Type of Input: Gun
Type of signal: Pulsed
This feature allows a customer that uses dual purge
applicators to use two resin pumps that share a
common catalyst pump and pushout the resin with
solvent on one side of the dual purge applicator
while loading the other side of the applicator with
the next material to be sprayed. For additional
details on how to implement this feature, refer to"
Appendix L".
DISCRETE CHANNEL AND
GUN OUTPUTS
All discrete outputs have two terminals, one labeled
Hi and one labeled Lo. They operate very similar
