SAFETY INSTRUCTIONS
Ex/I.S. installation:
• For correct use and installation the manufacturer’s manual must be followed.
When programming the Transmitter by PC and communication interface or a
HART® terminal the intrinsically safe data shall be observed.
• The designation galvanic isolation between the transducer input and the
loop supply indicates signal isolation only. It shall not be interpreted as an
Intrinsically Safe galvanic isolation like an isolating barrier. Therefore ordinary
care in selecting barrier and grounding shall be considered.
• The apparatus must be installed in an enclosure with an Ingress Protection of
at least IP 20.
• The terminals 1 and 2 of the equipment have to be electrically connected to a
linear barrier located in the non hazardous area.
• For Ex/I.S. data, see chapter 7. Approvals Options.
The YTA70 is a head mount type of temperature transmitter that accepts
thermocouple or RTD input and converts it to a 4 to 20 mA DC signal for
transmission. The YTA70 specifies HART communication protocol for remote
configuration.
It is imperative that usres observe the instructions in this manual to ensure the
protection and safety of operators.
