Safety messages
This guide provides basic guidelines for installing the Rosemount 148 Temperature Transmitter. It does not provide instructions for detailed configuration, diagnostics, maintenance, service, troubleshooting, or installations. Refer to the Rosemount 148 Temperature Transmitter Reference
Manual for more instruction. The manual and this guide are also available electronically at Emerson.com/Rosemount.
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 restricions associated with a safe installation.
WARNING
Process leaks
Process leaks could result in death or serious injury.
Install and tighten thermowells or sensors before applying pressure. Do not remove the thermowell while in operation.
WARNING
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.
WARNING
Conduit/cable entries
Unless marked, the conduit/cable entries in the transmitter housing use a ½-14 NPT thread form. Entries marked "M20" are M20 X 1.5 thread form. On devices with multiple conduit entries, all entries 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.

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.

March 2020 Quick Start Guide

1 Software installation

Procedure
1. Place the Rosemount 148 PC Programmer CD_ROM into the drive.
2. Run setup.exe from Windows™ XP, 7, 8, or 10.
3. When first using the software, configure the appropriate COM ports by selecting Port Settings from the Communicate menu.
4. Install MACTek® modem drivers completely before beginning bench configuration on the Rosemount 148 system.
Note
The software defaults to the first available COM port.

Quick Start Guide March 2020

2 Configuration

2.1 Configuring the transmitter

The Rosemount 148 must be configured for certain basic variables to operate. Transmitters are pre-configured in the factory to order specifications or factory defaults. Configuration may be required if the transmitter is not configured or if the configuration variables need revision. This can be done in two ways: by ordering factory-configuration by Emerson Automation Solutions, or by using the Rosemount 148 PC Programming interface in a bench configuration setting. The Rosemount 148 PC Programming Kit includes configuration software and a communication modem. The Rosemount 148 device will need an external power supply of 12–42.4 Vdc for configuration. To configure the transmitter:
Procedure
1. Hook up the transmitter and a load resistor (250–1100 ohms) wired in series with the power supply.
2. Attach the modem in parallel with the load resistor and connect it to the PC.

2.2 Verify the transmitter configuration

If the transmitter has a sensor connected (either a test sensor or actual installation hardware), the configuration can be checked using the Information tab on the Rosemount 148 PC Programmer interface. Select Refresh to update the status and confirm that the transmitter has been configured correctly. If there are any problems, refer to the Reference
Manual for troubleshooting suggestions.

4 Connect the wiring

4.1 Diagrams and power

Wiring diagrams are located on the top label of the transmitter.
An external power supply is required to operate the transmitter.
The power required across the transmitter power terminals is 12 to 42.4
Vdc (the power terminals are rated to 42.4 Vdc).
Note
To prevent damaging the transmitter, do not allow terminal voltage to drop below 12.0 Vdc when changing the configuration parameters.

4.2 Power the transmitter

Procedure
1. Connect the positive power lead to the “+” terminal.
2. Connect the negative power lead to the “–” terminal.
3. Tighten the terminal screws.
4. Apply power (12–42 Vdc).
