The Javelin D is easy to set up and program because
everythingisdoneusingthesimplefour-buttonprogramming
method. There are no jumpers, and no need to ever open the
case.After completing setup of one meter, additional meters
can be “cloned” using the time-saving Copy function.

User Friendly Menu Structure
To simplify programming, the Javelin’s setup functions are
divided into two menus. A main menu handles all the basic
setup functions.
An advanced features menu handles the special functions
not commonly used.
•Press the Menu button to enter or exit the Programming
Mode at any time.
•Press the Right arrow button to move to the next digit
during digit programming.
•Press the Up arrow button to scroll through the menus,
decimal point, or to increment the value of a digit.
•Press the Enter/Ack button to access a menu, accept a
setting, or to acknowledge relays.
Setting Numeric Values
The numeric values are set using the Right and Up arrow
buttons. Press the Right arrow button to select next digit and
the Up arrow button to increment the digit value.
The digit being changed is displayed brighter than the rest.
Press the Enter/ACK button, at any time, to accept a setting
or the Menu button to exit without saving changes.

Main Menu
The main menu consists of the three most commonly used
functions: Setup, Program, and Password. Press the Menu
button to enter the Programming Mode then press the Up
arrow button to scroll main menu.
The Setup menu is used to select the input signal, °F or
°C, and relay setup. The Program menu is used to calibrate
the meter. The Password menu is used to program a
password.
The display moves to the next menu after the Enter/ACK
button is pressed.

Advanced Features Menu
To simplify the setup process, the least used features in
most applications are located in the Advanced Features
menu.
To access the Advanced Features menu, press and hold the
Right arrow button first and then press and hold the Menu
button for three seconds.

The meter can be programmed to filter small input changes
(with the noise filter function), but allow larger input changes
to be displayed immediately by setting the noise filter bypass
function accordingly. If the change in input signal exceeds
the bypass value, no filtering will occur and the new value
will be displayed immediately.

All relay functions are set up from the front panel
• Automatic reset only
• Automatic or manual reset
• Latching or non-latching relays
• Alternation control
•On and off time delays from 0 to 199 seconds
•Fail-safe operation is user selectable
Maximum/Minimum Readings
To display the maximum and minimum readings since the
last reset/power-up, use the MAX button.
Serial Communication (SerL)
This menu is used to program the Serial communication
parameters such as the address for each meter when used in
a multi-drop mode.
The meter is equipped with serial communication capability as
a standard feature using PDC Serial Communication Protocol.
The Modbus RTU Protocol is optional and can be purchased
at any time.
Meter Copy (Copy)
The Copy function is used to copy (or clone) all the
settings from one Javelin D meter to other Javelin D
meters
In less than 5 seconds!
The Copy function is a standard feature on all meters, and
does not require a serial communication adapter.
Diagnostic Menu (diag)
The Diagnostic function aids in troubleshooting by
providing a convenient way to review setup and
programming parameters.

The Protocol selection menu is used to select either
the PDC or the Modbus protocol. If Modbus option is
purchased separately, it is necessary to enter a four-digit
code to permenantly enable the Modbus protocol.
Select Menu (SELc)
The Select menu is used to select display intensity. Selection
for analog output is a factory setting depending on the option
installed.
Voltage Input
The Javelin D is factory calibrated to accept DC voltages
up to 300 VDC.

The NEMA 4 and NEMA 4X enclosures are available in plastic,
stainless steel, and steel. They come with pre-punched 1/8 DIN
cutouts for up to ten meters. The meters are mounted in the
enclosure door so they can be programmed without opening the
enclosure. Options include 2"pipe mounting kits and engraved
plastic labels.
See the Trident Enclosures data sheet for complete details and
specifications regarding the NEMA 4 and NEMA 4X Enclosures.

These custom engraved plastic labels are the perfect
solution for identifying both the enclosure and labeling each
individual meter.
Whether the meters are mounted in one of our enclosures
or installed into your existing control panel these custom
engraved plastic labels are the answer you’re looking for!
The PDA2801 is a
low-cost, compact,
plastic NEMA 4X
enclosure that will
house one Javelin.
