Note: the HART current output (source mode or sink mode) of the current output module are safely electrically
isolated from earth and all other circuits.
Schedule of Limitations:
1) The interface circuit RS485 serves exclusively for intercommunication of the probes and must not be
connected to an external RS485 circuit.
2) In gas atmospheres for the choice of Group IIB or IIC for the intrinsically safe circuits, all intrinsically
safe circuits and the scintillation meter LB 480 series shall be fully operated in the selected Group IIB or
IIC.
