Fault

This output is energized anytime a fault condition

is recognized by the software. Even if the fault

is disabled (turned off) on the Configured Alarms

screen, this output will be energized as long as

the condition persists. Fluid flow will not be halted

when this output is energized unless it is con-fig-

ured to do so on the Configured Alarms screen.

Ready

This output is energized if the gun is configured

properly, a good job number has been loaded,

and the gun has been placed in run mode. This

output goes off if a fault occurs.

Spray Shutdown

This output is energized if a fault condition exists

and the specific fault that exists is enabled on

the Configured Alarms screen (turned on). This

indicates that the flow of fluid from the fluid panel

has been stopped as the result of a detected fault

condition.

Flush Request

This output is energized when the pot-life timer

has expired from the mixed material. (For more

information, see "Mixed Volume and Pot-Life

Timer" in the "Operation" section.)

Motor On

This output is energized by the software when it

wants to control the motor. It is connected to the

input of the motor amplifier that causes the motor

to be controlled. Do not connect external devices

to this terminal.

Motor Amp Reset

This output is energized by the software when it

is necessary to reset a faulted motor amplifier.

Typically, by pushing the Clear Faults button on

the front panel or by pulsing the Halt/Reset digital

input, this output will be energized momentarily

to reset the amplifier. Do not connect external

devices to this terminal.

ANALOG INPUTS

Analog inputs are jumper selectable to be 0 to 10

VDC or 4-20 mA with the exception of the hardener

flow sensor which is fixed at 4-20 mA.

Hardener Flow

Type of Input: Channel

Type of Signal: Fixed at 4-20 mA

Factory Setting: Not applicable

This is a 4-20 mA input that is normally connect-

ed to the output of a thermal shedding type flow

sensor placed in the catalyst fluid stream. Since

the feedback from the motor tachometer can only

indicate that the motor is turning and not that fluid

is actually flowing, this optional sensor is added to

prevent spraying fluid without any catalyst.

Flow Rate

Type of input: Gun

Type of signal: Jumper Selectable

Factory Setting: 0-10 VDC

This input is used if it is desired to have the ability to

vary the flow rate as the unit is spraying. Minimum

and maximum flow rates are programmed and an

external device (robot, PLC, potentiometer, etc.)

controls the actual flow rate by varying the input

between 0 and 10 volts or 4 and 20 milliamps.

(See "Minimum Flow and Maximum Flow in the

"Operation" section.)

Feather Pressure

Type of Input: Gun

Type of Signal: Jumper Selectable

Factory Setting: 4-20 mA

This input allows an optional pressure sensor to

be placed near the spraygun. Handgun operators

can use this to program a set feather pressure

at the inlet of the spraygun and the RCS-2 will

maintain that pressure while spraying.
