3. Introduction
3.1 Purpose and use of this manual
The content of this technical documentation and of its various
annexes is intended to provide information on the HART
®
Interface of
the LP Series. All safety related information is in the product specic
operation manual.
3.2 Used symbols and warnings
Warnings are intended for your personal safety and for avoidance
of damage to the described product or connected devices. In this
documentation, safety information and warnings to avoid dangers that
might affect the life and health of personnel or cause material damage
are highlighted by the preceding pictogram, which is dened below.
4. Safety instructions
4.1 Intended use
The purpose of this document is to provide detailed information on
the protocol interface. All safety related information is in the product
specic operation manual. Consult the operation manual before
connecting to the level transmitter.
5. Quick start-up guide
5.1 Before you begin
Tools needed:
• 24 Vdc linear regulated power supply
• Current meter
5.2 Quick start-up procedure
1. Connect 24 Vdc power supply to Loop 1.
2. Turn on power supply.
3. Connect Current Meter to test pins on interconnect board.
4. Move the oat towards the tip of the pipe and verify 4 mA set
point.
5. Move the oat towards the top of the pipe and verify 20 mA set
point.
6. If using two oats, repeat steps 4 and 5 for second oat. Note
both oats must be present or else the level transmitter will go
into alarm.
Before starting the operation of the equipment read this documentation
thoroughly and follow the safety information.
Symbol Meaning
This symbol is used to point to situations
that may lead to material damage and/or personal
injury.
7. Turn off power and disconnect power supply and current meter.
8. Install in tank.
6. Display Menu
All LP-Series liquid level transmitters are shipped with a Stylus (MTS
Part # 404108) to be used for manipulating the display. For single and
dual cavity housings, the Stylus is designed to allow for programming
of the unit without removing the housing. When using the Stylus make
sure to align the Stylus with the shape outline around the buttons in
the same orientation. Failure to correctly align the Stylus can cause the
display to not function properly.
Note:
Do not use any device other than the MTS Stylus to operate the display
on the LP Series.
Note:
Improper use of the Stylus can cause the display to not function
properly.
6.1 Operation Modes
The LP Series level transmitter runs in one of the following modes of
operation. You can use these modes to calibrate and set up various
operating parameters.
6.1.1 Run Mode
Run mode is the primary mode of operation. This mode will perform
measurements, display data, and respond to HART
®
commands.
6.1.2 Program Mode
Program mode is the primary mode for commissioning and trouble-
shooting the level transmitter. The full menu and available functions are
shown in section 6.3 Menu Structure. To enter program mode use the
Stylus and press the Enter Key as shown in section 6.2 Display Diagram.
Program Mode is protected by a password to keep unwarranted chan-
ges from occurring. The factory default password is 27513. When in
program mode, remote communications are not functional. An automa-
tic timeout feature is provided so that the transmitter does not remain
inadvertently in program mode. The timeout is set for 1 minute before
prompted for additional time. Total timeout is 2 minutes.
Note:
Whenever program mode is exited from the display the unit will reset
itself to insure all changes have been accepted. The reset will take
approximately 5 seconds before the level transmitter is able to respond
to commands.
Note:
In program mode, the transmitter will not respond to incoming HART
®
commands. A busy error will be sent to the controller to notify the
unit is in program mode. This function will prevent a user at a remote
terminal from programming the unit while a user is accessing program
mode from the display.
Note:
Output will vary depending on the location of the 4 and 20 mA set
points.
