Powder Level Sensor Operation
Hopper Operation
When the level of powder falls below the level sensor, a delay timer
(field-adjustable) is started. When the delay timer runs out, the virgin transfer
pump is turned on to refill the hopper. When the level sensor detects powder,
the virgin transfer pump is turned off. If the level sensor detects no powder for
greater than 3 minutes (field-adjustable), the low powder alarm is turned on.
Silencing the Low Powder Alarm
Touch the alarm silence icon on the touch screen.
