3.1 Unpacking and inspection
Complete the following steps when you unpack your instrument.
1.
Inspect the shipping container. If there is damage, contact the shipper immediately
for instructions.
2. If there is no apparent damage, remove the transmitter.
3. Ensure that all items shown on the packing list are present. If items are missing,
contact your local Customer Care representative.
4. Save the shipping container and packaging.
They can be reused to return the transmitter to the factory in case of damage.
3.2 Installation
3.2.1 General information
1. The transmitter tolerates harsh environments. For best results, install the
transmitter in an area where temperature extremes, vibrations, and
electromagnetic and radio frequency interference are minimized or absent.
2. To prevent unintentional exposure of the transmitter circuitry to the plant
environment, keep the security lock in place over the circuit end cap. To remove the
circuit end cap, loosen the lock nut until the tab disengages from the cap end and
then unscrew the cover.
3. The transmitter has two 3/4 inch conduit openings, one on each side of the housing.
Run sensor cable through the left side opening (as viewed from the wiring terminal
end of the transmitter) and run power wiring through the right side opening.
4. Use water tight cable glands to keep moisture out of the transmitter.
5. If conduit is used, plug and seal the connections at the transmitter housing to
prevent moisture from getting inside the transmitter.
CAUTION!
EQUIPMENT DAMAGE
Moisture accumulating in the transmitter housing can affect the performance of the
transmitter and may void the warranty.
6. If the transmitter is installed some distance from the sensor, a remote junction box
with preamplifier in the junction box or in the sensor may be necessary. Consult the
sensor instruction manual for maximum cable lengths.
