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 fresh
powder transfer pump is activated to refill the hopper. When the level
sensor detects powder, the fresh powder transfer pump is turned off. IF the
level sensor detects no powder for more than three minutes
(field-adjustable), the low powder alarm turns on.
The sensing distance can be changed by adjusting the potentiometer on the
sensor.
