1 About this guide

This guide provides basic guidelines to install the Rosemount 248 Head Mount Temperature Transmitter. It does not provide instructions for detailed configuration, diagnostics, maintenance, service, troubleshooting, or installations. Refer to the Rosemount 248 Temperature Transmitter
Reference Manual for more instruction. The manual and this guide are also
available electronically at Emerson.com/Rosemount.

1.1 Safety messages

WARNING
Explosions
Explosions could result in death or serious injury.
Installation of device in an explosive environment must be in accordance with appropriate local, national, and international standards, codes, and practices.
Review the Hazardous Locations Certifications for any restrictions associated with a safe installation.
Process leaks
Process leaks could result in death or serious injury.
Install and tighten thermowells and sensors before applying pressure. Do not remove the thermowell while in operation.
Electrical shock
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical shock.
Unless marked, the conduit/cable entries in the housing use a ½–14 NPT thread form. Entries marked “M20” are M20 × 1.5 thread form. On devices with multiple conduit entries, all entries will have the same thread form. Only use plugs, adapters, glands, or conduit with a compatible thread form when closing these entries.
When installing in a hazardous location, use only appropriately listed or Ex certified plugs, glands, or adapters in cable/conduit entries.
Quick Start Guide 3
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users’ equipment. This could be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for all systems used within the facility.

2 Configuration

2.1 Bench calibration

There are three ways to configure the transmitter:
• Field Communicator
• Rosemount 248 PC Programming Kit
• Custom at the factory using the C1 option code
Refer to the Rosemount 248 Reference Manual and the Field Communicator
User Guide for more information.
Connecting a field communicator
The Field Communicator Field Device Revision Dev v1, DD v1or later is required for complete functionality.

Quick Start Guide 5

2.2 Verify transmitter configuration

To verify operation using a Field Communicator, refer to the Rosemount 248
Reference Manual for more detailed description.

2.3 Install PC programmer kit (HART® 5 only)

Procedure
1. Install all necessary software for PC configuration: a) Install the Rosemount 248C software
1. Place the CD-Rom in the drive.
2. Run setup.exe from Windows™ 7, 8, 10, or XP.
b) Install the MACTek® HART modem drivers completely before
beginning bench configuration with the Rosemount 248 PC Programming system.
Note
For USB modem: Upon first use, configure appropriate COM ports within the Rosemount 248 PC software by selecting Port Settings from the Communicate menu. The USB modem driver emulates a COM port and will add to available port selections in the software’s drop-down box. Otherwise software defaults to first available COM port, which may not be correct.
2. Set up configuration system hardware: a) Hook up the transmitter and load resistor (250-1100 ohms)
wired in series with the power supply. The device will need an external power supply of 12-42.4 Vdc
for configuration.
b) Attach the HART modem in parallel with the load resistor and
connect it to the PC.

5 Perform a loop test

5.1 Overview

The loop test command verifies transmitter output, loop integrity, and operation of any recorders or similar devices installed in the loop.
Note
This is not available with the Rosemount 248C Configuration Interface.

5.2 Initiate loop test

Procedure
1. Connect an external ampere meter in series with the transmitter loop (so the power to the transmitter goes through the meter at some point in the loop).
2. From the Home screen, select: 1. Device Setup → 2. Diag/Serv → 1. Test Device → 1. Loop Test
3. Select a discrete milliampere level for the transmitter to output. At Choose Analog Output, select 1. 4 mA, 2. 20 mA, or 3. Other to manually input a value between 4 and 20 mA.
4. Select Enter to show the fixed output.
5. Select OK.
6. In the test loop, check that the fixed mA input and the transmitter’s mA output are the same value.
5.3
16
Note
If the readings do not match, either the transmitter requires an output trim or the current meter is malfunctioning.
After completing the test, the display returns to the loop test screen and allows you to choose another output value.

End the loop test

Procedure
1. Select 5. End.
2. Select Enter.
