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 , then press , then press 5 times. The following screen will be displayed.
