LOOP POWERED INDICATOR OVERVIEW
Model LPI-1 is a microcontroller based Loop Powered Indicator that incorporates
bright, 4 Digit Seven Segments LED or 4 Digit high contrast Seven Segment LCD
Display indicating process value. It does not require any external Power supply to
run its own circuitry. The instrument is designed to take power and display
process value from the 4mA to 20mA current loop. Having front key operation,
Instrument is easily programmable for any values between -1999 to 9999 and
decimal point.
Loop Powered Indicator is available in three mounting types; Panel Mount,
Wall Mount and 2” Pipe Mount (Explosion Proof).

To ensure that the device can be operated safely and all functions can be used,
please read these instructions carefully.
Installation and startup must be carried out by qualified personnel only.The
relevant country-specific regulations must also be observed.
Before startup it is particularly important to ensure:
Terminal wiring :Check that all cables are correctly connected according
All wiring must confirm to appropriate standards of good practice and local
codes and regulations. Wiring must be suitable for Voltage, Current and
Temperature rating of the system.
Unused control terminals should not be used as jumper points as they may
be internally connected, which may cause damage to the unit

ROTATING DISPLAY DIRECTION
The loop Powered indicator display is designed so that it can be rotated in 90 degree increments.This is accomplished by ordering the unit as a horizontal
pipe mount or a vertical pipe mount.However there may be the need for the customer to change the angle of the display.The following are procedures for
the display rotation.
(1) Remove power from the unit.
(2) Remove the glass cover from the display side.
(3) Remove Display PCB by pressing 4 spacers, holding the display PCB to the standoffs.
(4) Rotate the display to the desired position (can be rotated in 90 degree increments).
(5) Replace and tighten firmly the 4 spacers into the standoffs.
(6) Fit the glass cover.
