Level Sensor Modules
Lance Mounted Level Sensor Function
When the powder source switch is set to Hopper, the lance is lowered down
into the powder in the hopper to the position determined by the hopper
proximity switch on the lift cylinder. The hopper level sensor is positioned to
maintain the desired level of powder in the hopper, turning on and off the
virgin transfer pump as the powder level rises and falls. If the level sensor
detects a low powder condition for greater than 3 minutes (field adjustable),
the low powder alarm is turned on.
When the powder source switch is set to Box, the lance is lowered until the
box level sensor contacts the powder. When the powder level falls below
the level sensor, the lance is lowered further into the box. The box proximity
sensor on the lift cylinder prevents the lance from crashing into the bottom
of the box.
To adjust the position of each level sensor for the application, loosen the
clamp screw (4) with a hex key.
