1.1 Unpacking
Remove the packing list and verify that you have received all equipment. If
you have any questions, contact the nearest Customer Service
Department, as listed on the cover of this manual.
Upon receipt of shipment, inspect the container and equipment for any
signs of damage. Note any evidence of rough handling in transit.
Immediately report any damage to the shipping agent.
Note: The carrier will not honor any claims unless all shipping
material is saved for their examination. After examining and
removing contents, save packing materials and carton in the event
reshipment is necessary.
1.2 Safety and EMC Considerations
This instrument is a Class III device (8 to 35 Vdc).
Always use a power supply, which complies with EN 60950 safety
standard.
•
Do not expose the transmitter to rain or condensing moisture.
•
Do not operate the transmitter in flammable or explosive atmosphere.
•
As with any electronic instrument, you may encounter high voltage
exposure when installing, calibrating or removing parts of the
transmitter.
EMC Considerations
•
Whenever EMC is an issue, always use shielded cables.
•
Never run signal and power wires in the same conduit.
•
Use signal wire connections with twisted-pair cables.
•
Install Ferrite Bead(s) on signal wires close to the instrument if EMC
problems persist.
Failure to follow all instructions and warnings may result in injury!
1.3 General Description
The Two-Wire RTD Transmitter will produce a standard 4-20mA output
signal proportional to that produced by its RTD input temperature sensor.
Transmission of the proportional current output may be accomplished by
using inexpensive copper wire. The RTD transmitter accepts two-wire or
three-wire ohm platinum RTD sensors (PT100,alpha = 0.00385).
