Ransburg RCS 2 Ratio Control System - Manual (Page 37)

Alarm Tolerance Time
This parameter is in seconds and can be any value
from 0.000 to 20.000 seconds. This parameter al-
lows users to program how long an error condition
can persist before the unit issues a fault for that
gun. Users are warned against programming this
value too small as nuisance faults may become
a problem. A value of 3.000 seconds has been
found to be a good value for most applications.
Solvent Pulses Per Liter
This parameter can be any integer value for 1 to
100,000 pulses per liter.
This value is used by totalization software to track
the amount of flush solvent used by the gun
.
Horn Code
This allows the user to enable or disable the horn
(on top of the control console) for various errors
and faults. There are 6 possible settings for this
parameter:
a. Disabled - the horn will not sound for any
gun faults or errors.
b. SSD - the horn sounds only if a Spray
ShutDown for that gun occurs.
c. AE - the horn sounds if Any Error occurs on
that gun, even if they are not programmed to
cause a spray shutdown.
d. PLT - the horn sounds if the Pot-Life Timer
expires.
e. SSD+PLT - the horn sounds if either a spray
shutdown occurs or a pot-life timer expires for
that gun
f. AE+PLT - the horn sounds if any gun errors
occur or if the pot-life timer expires.
Default Job Number
This parameter can be any integer from 1 to 199.
It indicates which job number an operator wants
to automatically load into the gun upon power up
of the system.
Mixed Volume
The range of allowable volumes for this param-
eter is from 1 cc to 5000 cc. This volume is the
amount of material in the fluid lines between the
mix-block and the applicator or applicators. It
is used by the pot-life timer to keep track of the
age of the mixed material. If the material in the
applicator (the ma-terial that has been mixed the
longest) exceeds the programmed pot-life of the
material, a flush request is issued by the RCS-2
for that gun.
Tolerance Percentage
Allowable value for this parameter is any integer
form 1% to 100%.
This parameter indicates how far off from the
target flow rate any channel is allowed to be or
how far off from the target ratio the actual ratio
is allowed to be before a fault is issued by the
RCS-2 controller.
Tolerance Volume
Allowable volumes for this parameter are from
0 cc to 255 cc's.
This parameter indicates how often the software
verifies that the actual ratio being expelled from
the fluid panel is within the programmed tolerance
limit of the target ratio. Every time this volume of
material passes out of the mix tube, the controller
calculates the actual ratio based on the actual
volume of resin and the actual volume of catalyst
that was contained in that sample. It then compares
that ratio to the target ratio and checks to see if
the actual ratio is within the tolerance limit of the
target ratio. If not, a Ratio Out of Tolerance Fault
is issued by the controller.
If a 0 (zero) is entered for the tolerance volume
prarameter, ratio is automatically checked every
10 milliseconds. This check,however, is based
on flow rate data, not volume data.
