Rice Lake CB-2 Concrete Batch Controller Version 2.0 - Manual (Page 39)

Installation/Operation Manual - Configuration of User Parameters 35
Zero Tolerance Band On a hopper type scale, the tolerance band for the initial empty condition
Cleanout Time On a hopper type scale, amount of time in seconds to keep the discharge
gate open after it has reached the empty level to allow it to totally empty.
Close Time For scales with a discharge gate that does not have a limit switch, the amount
of time in seconds the gate takes to close.*
Discharge Delay Time in seconds after the discharge cycle begins before this scale’s
discharge is to begin
Start Discharge % Full For the cement scale, this indicates the % of the aggregate remaining to be
discharged before the cement discharge will begin. This parameter is ignored
for the aggregate or water scales
Target Discharge Rate
Start Vibrator Weight Weight below which the vibrator will be operated
Wide Open Weight For a hopper type scale, the weight below which the inching gate will be
opened fully.
For the aggregate scale, if the cement scale is still discharging when the
remaining total aggregate weight to be discharged drops below this weight,
the aggregate discharge gate will be closed until the cement hoper has
finished discharging
Gate Open Time Time in seconds for the discharge gate to open fully.*
Inch Time Time in milliseconds to pulse the open or close output to inch an inching
gate.*
Initial Burst Time Time in seconds to hold on the open output to initially open an inching gate.*
Control Rate Filter Number of samples to average to calculate the flow rate
Discharge Rate Tolerance Discharge rates within this tolerance % of the target rate will not cause any
gate adjustment..
Total Under Tolerance Percentage of total weight the scale may be below the total target.
Total Over Tolerance Percentage of total weight the scale may be above the total target
Discharge Controls Connection to additional scale data
* For decumulative scales with more than one material bin, these values are specified with the “location” definition for the individual
materialsm
Gate Open Output Digital output address of port used to open the discharge gate
Gate Close Output Digital output address of port used to close the discharge gate
Vibrator Output Digital output address of port used to run the vibrator.
Aerator Output Digital output address of port used to run the aerator during the discharge
Limit Switch Present No
Yes Discharge gate closed limit switch exists
Limit Switch Input Digital input address of port used to receive the gate closed limit switch signal
Gate Type Open/Closed
Inching
Skiphoist Discharge gate is either simple open/closed or inching type or skiphoist.
Skip Hoist Up Control Output port for signal used to move bucket to top posit
Skip Hoist Down Control Output port for signal used to move bucket up to 75% position
Skip Hoist Mid Control Output port for signal used to return bucket to bottom position
Skip Hoist Up Signal Input port for signal that bucket is in top position
Skip Hoist Down Signal Input port for signal that bucket is at 75% position
Skip Hoist Mid Signal Input port for signal that bucket is in bottom position
