EN.IO.LI.24.ALW IDENTIFICATION 5.1. Manufacturer's address APLISENS S.A. 03-192 Warsaw Morelowa 7 St Poland 5.2. Transmitter identification Depending on the version of the transmitter, the nameplates may differ in the amount of information and parameters. Table 1. Symbols occurring on the transmitter nameplate. -
Page 9: Construction
The transmitter is provided with an output interference filter and overvoltage protection components. Fig. 1 shows the block diagram of the transmitter. LI-24ALW transmitter monitors its hardware re- sources and calculation accuracy. In case of a failure the transmitter specifies an error code on the LCD display and generates alarm current in the current loop. -
Page 10: Installation
INSTALLATION 7.1. General recommendations Temperature transmitter LI-24ALW can be mounted in any position. The housing of the transmitter should be protected against hot air streams by appropriate location of the transducer or by installing thermal screens so that the transmitter does not heat up to a temper- ature higher than the permissible one. -
