Quick Start Guide
NOTICE
This installation guide provides basic guidelines for the Rosemount 148. It does not provide instructions for
detailed configuration, diagnostics, maintenance, service, troubleshooting, or installations. Refer to the
Rosemount 148 Reference Manual (Document No. 00809-0100-4148) for more instruction. The manual and
this QIG are also available electronically on www.rosemount.com.
Explosions could result in death or serious injury:
Installation of this transmitter in an explosive environment must be in accordance with the appropriate local,
national, and international standards, codes, and practices. Please review the Hazardous Locations
Certifications for any restrictions associated with a safe installation.
Process leaks may cause harm or result in death
Install and tighten thermowells or sensors before applying pressure.
Do not remove the thermowell while in operation.
Electrical shock can result in death or serious injury
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical
shock.
Conduit/Cable Entries
Unless marked, the conduit/cable entries in the transmitter housing use a 1/2-14 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
entries.
When installing in a Hazardous Location, use only appropriately listed or Ex certified plugs, adapters or
glands in cable/conduit entries.

Step 1: Software installation
1. Install the 148 PC Programmer software.
Place the 148 PC Programmer CD_ROM into the drive
Run setup.exe from Windows NT, 2000, or XP
2. When first using the 148 PC software, configure the appropriate COM ports by
selecting “Port Settings” from the “Communicate” menu.
3. Install MACTek Modem drivers completely before beginning bench
configuration on the Rosemount 148 system.
Note:
The software defaults to the first available COM port.
Step 2: Configure
The Rosemount 148 must be configured for certain basic variables to operate. In
many cases, all of these variables are pre-configured at the factory. 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, 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.
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.
Please see Table 1 for Spares Kit and re-order numbers. For more information,
refer to the Rosemount 148 Reference Manual (Document No.
00809-0100-4148).
Table 1. Rosemount 148 Programming Kit Spare Part numbers
Verify transmitter configuration
If the transmitter has been connected to a sensor (either a test or installation
mounting hardware), the configuration can be checked using the Information tab
on the 148 PC Programmer interface. Click 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.

Step 3: Mount the transmitter
To prevent moisture from draining into the transmitter housing, mount the
transmitter at a high point in the conduit run.
Typical European and Asia Pacific installation
Head Mount Transmitter with DIN plate style sensor
1. Attach the thermowell to the pipe or process container wall. Install and
tighten the thermowell before applying process pressure.
2. Assemble the transmitter to the sensor. Push the transmitter mounting
screws through the sensor mounting plate and insert the snap rings (optional)
into the transmitter mounting screw groove.
3. Wire the sensor to the transmitter.
4. Insert the transmitter-sensor assembly into the connection head. Thread the
transmitter mounting screw into the connection head mounting holes.
Assemble the extension to the connection head. Insert the assembly into the
thermowell.
5. Slip the shielded cable through the cable gland
6. Attach a cable gland into the shielded cable.
7. Insert the shielded cable leads into the connection head through the cable
entry. Connect and tighten the cable gland.
8. Connect the shielded power cable leads to the transmitter power terminals.
Avoid contact with sensor leads and sensor connections. (See Step 4 for
instructions on grounding the shield wire.)
9. Install and tighten the connection head cover. Enclosure covers must be fully
engaged to meet explosion-proof requirements.

Typical North and South American installation
Head Mount Transmitter with Threaded Sensor
1. Attach the thermowell to the pipe or process container wall. Install and tighten
thermowells before applying process pressure.
2. Attach necessary extension nipples and adapters to the thermowell. Seal the
nipple and adapter threads with silicone tape.
3. Screw the sensor into the thermowell. Install drain seals if required for severe
environments or to satisfy code requirements.
4. Pull the sensor wiring leads through the universal head and transmitter. Mount
the transmitter in the universal head by threading the transmitter mounting
screws into the universal head mounting holes.
5. Mount the transmitter-sensor assembly into the thermowell. Seal adapter
threads with silicone tape.
6. Install conduit for field wiring to the conduit entry of the universal head. Seal
conduit threads with silicone tape.
7. Pull the field wiring leads through the conduit into the universal head. Attach
the sensor and power leads to the transmitter. Avoid contact with other
terminals.
8. Install and tighten the universal head cover. Enclosure covers must be fully
engaged to meet explosion-proof requirements

Step 4: Connect the wiring
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). To prevent damaging the
transmitter, do not allow terminal voltage to drop below 12.0 Vdc when
changing the configuration parameters.
Power the transmitter
1. Connect the positive power lead to the “+” terminal. Connect
the negative power lead to the “–” terminal.
2. Tighten the terminal screws.
3. Apply power (12 – 42 Vdc).
