CEOP8086
2.2 Receiver Connections and Installation Instructions
The receiver connection and installation instructions are shown below.
Under all circumstances, single phase loads only are to be connected to the receiver output
relays. Control of multi-phase loads such as poly-phases motors, etc, must be carried out
via a separate external multiphase contactor controlled by one of the three available output
relays.
For installations with multiple phases available to them, the individual single phase
controlled loads may be balanced across the available phases by using the multiple output
relays. For this arrangement, it is still a requirement that one active of one of the available
phases is looped to the receiver active link as per the connection and installation instruction.
It should be noted that installation and connection instructions are provided with each new
receiver and these guidelines must be adhered to. The guideline also acts as a drilling
template for the receiver footprint.
3 OPERATING PRINCIPLE
3.1 Decoder
The LCR212 processes all standard ripple control protocols and is also capable of handling a
second protocol with secured data transmission (VERSACOM).
Two decoders are needed due to the fact that two ripple protocols have to be processed:
one for conventional ripple control systems and one for VERSACOM.
