Alarm
Message:
Component hopper low on
material.
Component out of specifi-
cation.
Gate valve failure.
Material feed error.
Receivers material demand
exceeds alarm time.
Component hopper out of
material.
Possible Cause
Occurs ONLY with optional component
hopper proximity switches. A compo-
nent hopper proximity switch is not
covered.
Each component is programmed to
dose very accurately. Alarm occurs if
the dosed amount has an error greater
than Setup/ Component/ Alarm “Out of
specification” Setpoint.
Occurs if a component material dosing
valve leaks material, when it is sup-
posed to be closed.
Occurs if a material dosing valve, sud-
denly doses material at a rate that is
significantly different than a prior dose
rate.
Only occurs if blender has Loading
Option Hardware, and Loading Option
Software is enabled. Alarm occurs if
the receiver fill time exceeds the alarm
time set in Loading/ Setup/ Loader/
Time “Alarm Time” Set point.
Only occurs if blender has Loading
Option Hardware, and Loading Option
Software is enabled. Alarm occurs if
there are TWO blenders being loaded
with ONE vacuum Pump AND the
Ethernet communication link between
the two blender touch screens has failed.
Solution
Check the component hopper to be
sure material is present. Adjust prox-
imity switch for proper operation.
Correct component hopper loading
problem.
This usually occurs if very LOW per-
centage doses are attempted. The
valve for this low dosed component
may be too large. Increase the Setup
Alarm parameter called “Out of
Specification” for that component.
Setup/ Component/ Alarm. Consult the
factory for additional assistance.
Check each component material dosing
valve to ensure it is not held open or
leaking material.
Check the component material dosing
valve to ensure it indexes open and
closed properly. Check the material
within the component hopper for mate-
rial bridging, or bridging from an
obstruction. In the Recipe screen, reset
the Material Calibration of the problem
component, and monitor for recur-
rence.
Check the component hopper to be
sure material is present. Correct com-
ponent hopper loading problem.
Repair the Ethernet Communication
link between the two blender touch
screens.
