Rice Lake CB-2 Concrete Batch Controller Version 2.0 - Manual (Page 5)

Installation/Operation Manual - Safety 1
About This Manual
This manual is intended for use by service technicians responsible for installing and servicing the CB-2 and the
end user who will be operating the CB-2 automated concrete batching system.
In this manual, you will see many references to the CB-2 and the 920i. To clarify, the CB-2 is a stand-alone batch
panel that includes Rice Lake’s 920i
® HMI digital weight indicator. The 920i is the heart and brain of the CB-2
and is responsible for weight/scale data as well as running the CB-2 batching program. The CB-2 also contains
additional hardware that is interfaced to the 920i. The majority of the additional hardware is for controlling the
batch plant through digital I/O and then through solid-state 120V/240V relay modules.
