SAFETY INSTRUCTIONS

Ex/I.S. installation:
• For correct use and installation the manufacturer’s manual must be fol-
lowed.
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 Protec-
tion 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. SAFETY APPROVALS.

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 re-
mote configuration.
It is imperative that usres observe the instructions in this manual to ensure
the protection and safety of operators.

6.WIRING

See wiring diagram. For output signal, use twisted pair or cables with
performance equivalent to 600V vinyl insulate cable. For wiring in high or
low temperature, use a wire or cable suitable for such temperature. Use
cables and wires which meet atmospheric conditions. Take necessary
measure to avoid corrosion or damage of cables and wires.
IMPORTANT
When mounting on a sensor head, do not overtighten the screws.

8.HART COMMUNICATION

8.1 Connection and Requirements

A standard HART communicator can be used for programming the YTA70.
The HART communicator must be loaded with the appropriate DDL driver
for YTA70.
Minimum loop resistance is 250Ω. If the receiving equipment has a lower
resistance, a serial resistor must be inserted to communicate with the
HART communicator.
