SAFETY ALERTS 

The symbols below are used on the equipment and throughout this 

document to draw the user’s attention to important operational and 

safety information. 

 

 

CAUTION: 

Read this manual carefully prior to 

installation and operation of the 

unit. 

CAUTION OR DANGER: 

Electric shock hazard 

All safety related instructions that appear in the manual must be 

observed to ensure personal safety and to prevent damage to either the 

instrument or the system.  If the device is used in a manner not 

specified in this manual, its safety features may be impaired. 

INTRODUCTION 

The N1500LC is an indicator designed for weighing system with load 

cells. It accepts a wide variety of electrical signals. It has a display 

with six-digit LED display for the measured value and device 

parameters. 
The whole device configuration is done through the keyboard without 

any change in the circuit. Thus, the selection of input type and the 

type of alarms action, besides other special functions are all 

accessed and programmed through the front keypad. 
It is important that you read this manual carefully before using the 

instrument. This is an electronic device that requires care in handling 

and operation, and if properly used, it will be very efficient in the work 

required. 
The main features of the basic version of N1500LC are as follows: 

 

Input: 4-20 mA, 0-20 mA, 0-50 mV, 0-20 mV e -20 a 20 mV; 

 

Increasing or decreasing display; 

 

10 Vdc (or 5 Vdc) power supply for load cells; 

 

Memory for maximum and minimum values; 

 

Hold, peak hold, tare, zero tare and automatic zero functions;  

 

Digital input; 

Optionally can have: 

 

Process Variable (PV) retransmission in 0-20 mA ou 4-20 mA; 

 

RS485 MODBUS RTU serial communication; 

 

3rd and 4th alarm relays. 

 
 
 
 

The front panel is shown below, with a description of its elements.

: Displays the value of the measured variable (PV) and the 

mnemonics of the device programming parameters. 

A1, A2, A3 

and

 A4

: show active alarms. 

Rx

 and

: indicate RS485 communication line is active. 

 

P

 

key 

- This key is used to access different displays with the 

programmable parameters of the device. 

 

BACK  key

  -  This key is used to go back to the previous 

parameter displayed in the menu display. 

 

INCREMENTS/ZERO key and 

 

DECREMENTS/ZERO 

key 

-

 

They make possible the change the parameter values. 

They are also used to display maximum and minimum 

values stored in memory. 

 

Key Special FUNCTION 

- This special function key is used for 

programmed functions as explained in the SPECIAL FUNCTION KEY 

section of this manual. 

PROCESS VARIABLE INPUT - PV 

The type of input to be used by the indicator must be set by the user 

via the keyboard, among types established in 

Table 1

All input types available are factory calibrated and require no further 

adjustment by the user, except the definition of range of indication.
