Screen IdentificationFault ScreensA fault is a type of error that stops the machine from operating. The following are potential fault screens that mayappear:These screens indicate that a material low level condition has occurred. This usually indicates that the material pailsneed to be changed. The low level indicators are adjustable to ensure as little waste as possible. Refer to PailChange-Over, page 34, for material changeover procedures. If the fault condition still exists after the “AcknowledgeFault” key is pressed, the alarm and fault screen will activate again. This will prevent an accidental reset withoutchanging the pails.The color injector is designed to dispense the entire contents in about 0.2 seconds. This depends on the air pressuresupplied to the color injector. The refill time is approximately the same as the dispense time. It also relies upon the airpressure supplied to the unit. The message will be generated when a shot size is too small. Refer to Adjust the ColorantInjector Shot Size, page 30.The pump listed in the screen title has traveled past the other pump by X amount of encoder counts in the downwarddirection, as defined on the Fault Preset Screen. This fault indicates that there is a problem with the pneumatic circuitthat allowed the pump to relax. When the pump is waiting for the activation signal from the injection mold machine, allof the valves are in the locked-center position, locking pressure inside the pumps for the next cycle.332312A 23
