MTL MTL4541

Not used voltage inputs 0 .. 5 V have to be terminated with jumpers. Not used current inputsare terminated with the shunt, not used voltage inputs 0...10 V with the voltage divider in thecable connector.

Notes to the safety-related operation and useScreened cables have to be used for the field input circuits, twisted cables are recommendedif it is sure that the environment of the transmitter up to the module is free from interferencesand the distance is relatively short (e. g. inside a cabinet) then the cabling can be performedwithout screened cables or twisted cables. However, the interference immunity of the analoginputs can only be achieved by using screened cables.

Planning notes for ELOP IIFor each input channel of the module exists an analog input value and an appertaining channelfault bit. With activated channel fault bit a safety-related reaction has to be programmed inELOP Il related to the corresponding analog input.

Recommendations for the use of the module according to IEC 61508, SIL 3Cables for power supply shall be locally separated from the input circuits,Application of a suitable earthing must be regarded,Measures against rising of the temperature have to be taken outside of the module, e. gfans in the cabinet,

Recording events in a logbook for operation and maintenance.

A maintenance of the module is not required. ln case of fault there is a switch-off. The failedmodule must be replaced.
