4. Connect an Earth ground wire to the nearest green ground screw
per local electrical code (not shown in illustration).
5. Connect the positive supply wire to the (+) terminal and the
negative supply wire to the (-) terminal.
6. Replace and tighten the cover to the wiring compartment of the
transmitter before applying power.

Configuration
Although the Jupiter Model JM4 transmitter can be delivered
pre-configured from the factory, it can also be easily reconfigured
in the shop or at the installation using the local LCD/Keypad,
HART communicator, or PACT
ware
/DTM. Bench configura-
tion provides a convenient and efficient way to set up the trans-
mitter before going to the tank site to complete the installation.
Before configuring any transmitter, collect all operating parame-
ters information.
Apply power to the transmitter and follow the step-by-step pro-
cedures below for the menu-driven transmitter display.
See Menu
Navigation and Data Entry Section 1.5.2
Information on configuring the transmitter using a HART com-
municator is given in Section 1.6.
1.5.1 Bench Configuration
The Jupiter Model JM4 transmitter can be easily configured at a
test bench by connecting a standard 24 VDC power supply di-
rectly to the transmitter terminals as shown in the accompanying
diagram. An optional digital multimeter is shown in the event
that mA current measurements are desired.
NOTE: Current measurements taken at these test points are an ap-
proximate value. Accurate current readings should be taken
with the digital multimeter directly in series with the loop.
NOTE: When using a HART communicator for configuration, a mini
-
mum 250-ohm line load resistance is required. Refer to your
HART communicator manual for additional information.
NOTE: The transmitter can be configured without the probe. Please
disregard the “No Probe” diagnostic indicator that will appear.
1.5.2 Menu Navigation and Data Entry
The four push buttons offer various forms of functionality for
navigation and data entry.
The Model JM4 user interface is hierarchical in nature, best de-
scribed as a tree structure. Each level in the tree contains one or
more items. Items are either menu labels or parameter names.
• Menu labels are presented in all capital letters
• Parameters are capital words
1.5.2.1 Navigating the Menu
UP
moves to the previous item in the menu branch.
DOWN
moves to the next item in the menu branch.
BACK
moves back one level to the previous (higher) branch
item.
ENTER
enters into the lower level branch or switches to the en-
try mode. Holding the ENTER down on any highlighted menu
name or parameter will show help text for the item.
1.5.2.2 Data Selection
This method is used for selecting configuration data from a
specific list.
UP
and
DOWN
to navigate the menu and highlight the item
of interest.
ENTER
allows modification of that selection.
UP
and
DOWN
to choose new data selection.
ENTER
to confirm selection.
Use
BACK
(Escape) key at any time to abort the procedure
and escape to previous branch item.
1.5.2.3 Entering Numeric Data Using Digit Entry
This method is used to input numeric data, e.g., Probe Length,
set 4mA and set 20mA.
Push Button
Keystroke Action
Up
Moves up to the next highest digit (0,1,2,3,....,9 or
decimal point). If held down the digits scroll until the
push button is released.
Down
Moves down to the next lowest digit (0,1,2,3,....,9 or
decimal point). If held down the digits scroll until the
push button is released.
Back
Moves the cursor to the left and deletes a digit. If
the cursor is already at the leftmost position, then
the screen is exited without changing the previously
saved value.
Enter
Moves the cursor to the right. If the cursor is located
at a blank character position, the new value is saved.
All numeric values are left-justified, and new values are entered
from left to right. A decimal point can be entered after the first
digit is entered, such that .9 is entered as 0.9.
Some configuration parameters can have a negative value. In this
case, the leftmost position is reversed for the sign (either “-” for a
negative value, or “+” for a positive value).
