Tank Level Sensing and Velocity Change
(“ ”) Options (C6)
If tank level sensors are installed into the system, an
alarm is generated when a tank is almost empty. If the
feature is turned ON, a Tank A low (“
”), a Tank B
low (“
”), or a both tanks are low (“ ”) error will be
generated if the condition exists.
The machine also measures the piston velocity and
will generate an alarm if the piston velocity has
changed significantly since the machine was last
calibrated. A significant change is piston velocity,
usually caused by a change in air pressure, can
degrade shot size accuracy.
The user has the capability to turn the
feature OFF
by selecting a level of 0%, or ON by selecting
levels
of 20%, 40% or 60%. For instance, if 40% is selected,
and the piston velocity changes by + or – 40%, an error
code will be generated after the corresponding shot to
inform the operator of the situation. If the velocity
increases above the selected level, a
error will be
generated, and if the velocity decreases below the
selected level a
error will be generated.
The
feature is automatically disabled when the
machine is in Operator mode, or when the machine is
executing a purge shot.
From the Run screen, press
