To install Intrinsically Safe wiring:
1. Make sure the IS barrier is properly installed in the safe
area (refer to local plant or facility procedures). Complete
the wiring from the barrier to the Model 805 transmitter.
See
Agency Specifications – Intrinsically Safe Installations,
Section 3.4.1
.
2. Remove the cover to the wiring compartment of the trans-
mitter. Install the conduit plug in the unused opening.
3. Install a conduit fitting and pull the supply wires.
4. Connect shield to an earth ground at power supply and
leave floating at the transmitter.
5. Connect an earth ground wire to the nearest green ground
screw. (Not shown in illustration.)
6. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal.
7. Replace the cover to the wiring compartment of the
transmitter.

Configuring and Calibrating the
Transmitter (LCD version)
Before configuring the Model 805 transmitter, collect the
operating parameters information. Then, power-up the
transmitter. Information on configuring the transmitter
using a HART communicator is given in
Configuration
Using HART, Section 2.7
.
2.6.1 Operating Parameters
Some key information is needed to calibrate the Model
805 transmitter. Complete the configuration information
table. See
Configuration Information, Section 1.1.2
.
2.6.2 LCD Transmitter Display and Keypad
The Model 805 LCD transmitter has a liquid-crystal dis-
play (LCD) capable of showing two lines of 8 characters
each. Transmitter measurements and configuration menu
screens are shown on the LCD.
The transmitter default display is the measurement screen.
It cycles every 5 seconds to display LEVEL, %OUTPUT,
and LOOP information. The transmitter defaults to this
display after 5 minutes if no keystrokes are sensed.
The keypad has three arrows used to scroll through the
displays and to calibrate the transmitter – the Up ( ) or
Down ( ) Arrow keys and the Enter ( ) key.
Either the Lo Cal or Hi Cal point levels can be entered
first. It is not necessary to do the Lo Cal first. In addition,
the 4 mA and 20 mA setpoints can be entered for either
DIRECT action or REVERSE action as desired.
