1 First steps
1.1 Unpack and inspect
To unpack the instrument:
Procedure
1. Inspect the shipping container(s). If there is damage, contact the
shipper immediately for instructions.
2. If there is no apparent damage, unpack the container(s).
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 used to return the instrument to the factory in case of
damage.
1.2 Installation
1.2.1 Installation guidelines
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 ¾-in. (19.1 mm) 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 using conduit, 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.
Quick Start Guide 5
Quick Start Guide April 2020
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 Quick Start Guide for
maximum cable lengths.
1.2.2 Orient the display board
The display board can be rotated 90 degrees, clockwise or counterclockwise,
from the original position. To reposition the display:
Procedure
1. Loosen the cover lock nut until the tab disengages from the circuit
end cap. Unscrew the cap.
2. Remove the three bolts holding the circuit board stack.
3. Lift and rotate the display board 90 degrees, clockwise or
counterclockwise, into the desired position.
4. Position the display board on the stand offs. Replace and tighten the
bolts.
5. Replace the circuit end cap.

2.2.2 Wire the transmitter with HART® or FOUNDATION™ Fieldbus
Procedure
1. Run the power/signal wiring through the opening nearest terminals
15 and 16.
2. Use shielded cable and ground the shield to the power supply.
3. To ground the transmitter, attach the shield to the grounding screw
on the inside of the transmitter case.
You can also use a third wire to connect the transmitter to earth
ground.
Note
For optimum electromagnetic interference/radio frequency
interference (EMI/RFI) immunity, shield the power supply/output
cable and enclose it in an earth grounded metal conduit. Do not run
power supply/signal wiring in the same conduit or cable tray with AC
power lines or with relay actuated signal cables. Keep power supply/
signal wiring at least 6 ft. (2 m) away from heavy electrical
equipment. An additional 0-1 mA current loop is available between
TB-14 and TB-15. A 1 mA current in this loop signifies a sensor fault.
See Figure 2-2 for wiring instructions.

Use the IRC to read diagnostics messages, calibrate connected sensors, and
program the transmitter. Hold the IRC within 6 ft. (1.8 m) of the transmitter
and less than 15 degrees from the horizontal of the display window.

April 2020 Quick Start Guide
Guidelines for using IRC
• Do not use harsh chemicals or abrasive brushes when cleaning the
remote control.
• If the green LED does not light when you press a key, the issue is
probably a weak battery. To restore operation, remove four screws to
access and replace the two batteries. Observe the two warning messages
posted at the rear of the remote control.
• Requires two 1.5 V AAA batteries. If used in hazardous areas,
replacement batteries must be Energizer E92/EN92 or Duracell MN2400/
PC2400.
• All functions for remote control PN 24479-00 are the same as those for
the previous remote control, PN 23572-00.
