Pre-installation
Before installing the transmitter, there are several pre-installation steps that
should be completed to make the installation process easier:
•
Identify options and configurations that apply to your application
•
Set the hardware switches if necessary
•
Consider mechanical, electrical, and environmental requirements
Note
Refer to the product reference manual for more detailed requirements.
Identify options and configurations
The typical transmitter installation includes a device power connection, a
4-20mA output connection, and sensor coil and electrode connections.
Other applications may require one or more of the following configurations
or options:
•
Pulse output
•
Discrete input/discrete output
•
HART multidrop configuration
Hardware switches
The transmitter may have up to four user-selectable hardware switches.
These switches set the alarm mode, internal/external analog power, internal/
external pulse power, and transmitter security. The standard configuration
for these switches when shipped from the factory is as follows:
Table 3-1:

Alarm mode
Internal/external analog power
Internal/external pulse power
Transmitter security
The analog power switch and pulse power switches are not available when
ordered with intrinsically safe output, ordering code B.
In most cases, it is not necessary to change the setting of the hardware
switches. If the switch settings need to be changed, refer to the product
reference manual.
