6. Some further important advantages of the electronic alarm system arc:
— All transducer signals are individually processed, i. e. by one circuit board per measuring and alarm channel. If one of the channels should fail, the rest of the system will remain uneffected.
— Data for each channel, time delay, alarm group, scale gaud number of decimals, are set by programming on each circuit board.
— If necessary the system layout can be modified by the customer, by moving the transducer connections, the corresponding circuit board and the transparent legend plate, without the need for taking the programming into consideration.
— Each channel can be equipped with separate lamps for alarm indication on mimic diagrams and analog instruments, for continuous presentation of the measured values.
Look through the text and list the advantages of the electronic alarm system.
