UNCLASSIFIED OPERATIONAL PROCEDURE - Elster LCR-212 Single Phase Load Control Ripple Receiver Installation and Use CEOP8086 2.1 Receiver Indications LED Indications The LCR212 has two Led’s to indicate the function and the status of the receiver. LED 1: (green) indicates evaluation of audio frequency pulses. LED 2: (red) indicates the corresponding function status of the receiver as follows: 0.2 seconds ON/1.8 seconds OFF flashing rate normal functioning without AF signal. 0.5 seconds ON/0.5 seconds OFF flashing rate processing of a cyclic switching command. The red LED shows steady light during reception of a telegram. 22 March 2011 - Issue 3 Approved By: General Manager Technical Services Page 6 of 17 UNCLASSIFIED UNCONTROLLED COPY IF PRINTED
UNCLASSIFIED OPERATIONAL PROCEDURE - Elster LCR-212 Single Phase Load Control Ripple Receiver Installation and Use 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. 22 March 2011 - Issue 3 Approved By: General Manager Technical Services Page 7 of 17 UNCLASSIFIED UNCONTROLLED COPY IF PRINTED
