10.2 Configuration Parameters for CB-2 Weighed Materials Discharged Using an
Open Close Gate
When configuring the CB-2 for an open close gate it is important to know the time in seconds required to fully
open and close the gate. Manually open the discharge gate and record the amount of time in seconds required to
fully open the gate. Repeat a few times for accuracy. Average the time readings and this number will represent
the “fully open time” for the gate. This process can be repeated to calculate the “fully closed time”.

Scales
Aggregate (OR) Cement
Scale Type - Hopper
Close Time
Measured time in seconds to close the gate. This number will be used if the gate does not have a limit switch.
Gate Open Time
Measured time in seconds to fully open the discharge gate.
Wide Open Weight
When the material weight left to discharge falls below this value the inching gate will open fully. This adjustment
serves as a “clean out” action. The aggregate scale will not open fully even when the material weight falls below
this value until the cement has totally discharged. In this situation, the aggregate gate will close until the cement
is discharged and then open fully.
If this number is set too high material can overflow an aggregate belt if used. This parameter is applicable for a
hopper type scale.
