INTRODUCTION

N1500LC is a digital panel meter designed for a weighing systems with load cells. It accepts a wide variety of electrical signals. It has a display with 6-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. The main features of the basic version are as follows:.

• Input: 4-20 mA, 0-20 mA, 0-50 mV, 0-20 mV, and -20 to 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, it can have:
• Process Variable (PV) retransmission in 0-20 mA or 4-20 mA
• RS485 Modbus RTU serial communication
• 3rd and 4th alarm relays

The front panel is shown below:

Display: Displays the value of the measured variable (PV) and the mnemonics of the device programming parameters.
A1, A2, A3, and A4: Display active alarms.
Rx and Tx: Display RS485 communication line is active.

• P key: Key used to access different displays with the programmable parameters of the device.
• BACK key: Key used to go back to the previous parameter displayed in the menu display.
• INCREMENTS/ZERO key and DECREMENTS/ZERO key: Keys used to 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 AND DIGITAL INPUT section of this manual.

PROCESS VARIABLE INPUT − PV

The type of input to be used by the digital panel meter must be set via keyboard, among types established in Table 1. All input types available are factory calibrated and require no further adjustment, except the definition of range of indication.

ALARMS

The digital panel meter has 2 alarm outputs in the basic version and up to 4 alarms outputs optionally. Each alarm has a Warning Light in the front panel that shows when it was activated.

ALARM FUNCTIONS
The alarms can be set to operate in seven different modes. These modes are shown in Table 2 and described below. The alarm can also be set as disabled.

OPEN SENSOR – IERR
The alarm is triggered whenever the sensor breaks or is badly connected or broken.

LOW ALARM – LO
Triggered whenever the measured value is below the alarm Setpoint.

HIGH ALARM – KI
Triggered whenever the measured value is above the alarm Setpoint.

DIFFERENTIAL LOW – DIF.LO
Triggered whenever the measured value is below the point set by: (ALrEF – Deviation)

DIFFERENTIAL HIGH − DIF.KI
Triggered whenever the measured value is above the point set by: (ALrEF + Deviation)

DIFFERENTIAL (OR BAND) OUT OF RANGE − DIF.OU
For Differential alarm, it is necessary to define two parameters: Differential alarm reference value (ALrEF) and Alarm differential Setpoint (Deviation). The Differential out of range alarm occurs when the measured value is outside the range defined by: (ALrEF – Deviation) and (ALrEF + Deviation)

DIFFERENTIAL (OR BAND) WITHIN RANGE − DIF.IN
Same as previous but acting within the range defined above.

ALARM TIMER
N1500LC allows programming of the Time Setting of Alarms, being able to set delays in alarm conditions; send a single pulse at the time of trigger; or allow the generation of sequential pulses.
Table 3 shows these advanced functions. Times T1 and T2 can be programmed from 0 to 6500 seconds and are defined when setting up the device. For alarms with no time delays, set T1 and T2 with value 0 (zero). The warning LEDs associated with the alarm always light up when the alarm condition occurs, regardless of the status of the output relay, which may be de-energized momentarily due to a time delay.

Table 3 – Timer alarm functions

INITIAL BLOCK ALARM
The Initial Blocking option inhibits the alarm from being recognized if an alarm condition is present when the controller is first energized. The alarm will be triggered only after the occurrence of a non-alarm condition followed by a new occurrence for the alarm. The initial blocking is disabled for the Open Sensor alarm function.

SPECIAL FUNCTIONS

SPECIAL FUNCTION KEY AND DIGITAL INPUT
The key (special function key), as well as the Digital Input, may be assigned different functions that will be chosen during the setup. The possible functions are:

ZERO – ZERO FUNCTION

Available only for the key. It resets the scale. This function is used to eliminate the influence of interference or small deviations in the zero of a scale. Reset is only accomplished if the value shown in the scale is within 2 % of the end of scale. Zero is not lost if the scale is turned off.

Note: This function can be performed automatically using the parameters En A.z and A.Z.rAn.

LO – DISPLAYS MINIMUM
Set the key to, at the first touch, displays the minimum (Low) value the digital panel meter measured since the last reset. On the second touch, to show the maximum (High) measured by the digital panel meter since the last reset. On the third touch, the device returns to normal display. Press the button for more than 5 seconds to reset. This way, the minimum and maximum values will be erased, starting a new cycle.

XI – DISPLAYS MAXIMUM
Displays the maximum (High) value the digital panel meter measured since the last reset.

PKOLD – MAXIMUM VALUE
The digital panel meter will automatically work in the Peak Hold mode whenever the key or the digital input are programmed as PkoLd. This operation mode makes that the digital panel meter always shows the maximum value measured, since the last time the key or the Digital Input were pressed. Each activation of the key or digital input triggers a new Peak Hold cycle, resetting the reading of the display to the current value of the measure.

RST − CLEARS MAXIMUM AND MINIMUM

If configured with rSt, each activation of the key or digital input clear the memory for a new cycle of maximum and minimum values.

KOLD – FREEZE MEASURED VALUE
The Hold function freezes the measured value showed in the display. Each time the key or the Digital Input is selected, there is a change from Hold to normal mode.
Whenever the digital panel meter is in the Hold mode, the message koLd will be displayed so that the operator will be aware that the value displayed is the frozen value and not the current reading.

TARE – TARE FUNCTION
It is available only in the digital input configuration or through the key. It changes indication to zero (0000.0), regardless of the value applied to the input. It is used to eliminate indications of defined values. To eliminate the tare, you must press the key.

AND KEYS

The same Tare function available for the Digital Input can be quickly applied by using the key, which does not need to be set up. The key is used to eliminate the tare applied. The digital panel meter accepts successive tares, provided that the input signal (gross weight) does not exceed the end of the scale.

PROCESS VARIABLE RETRANSMISSION
As an option, the digital panel meter can be supplied with an isolated 0-20 mA or 4-20 mA analog output for Process Variable (PV) retransmission. Available at terminals 29 and 30 of the rear panel of the device. When this option is available, retransmission is always enabled and does not require any intervention. The PV values that define the scale of the 0 mA / 4 mA to 20 mA retransmission can be programmed in the high and low output limits (0v.lol and 0v.kol) at the Configuration Cycle. These limits can be defined freely, and you can make retransmission with increasing or decreasing behavior toward to the indicated value. For a voltage output signal, an external shunt (calibrated resistor) should be installed at the analog output terminals.

LOAD CELL POWER SUPPLY (AUXILIARY P. S.)
The digital panel meter provides a voltage power supply of 10 Vdc to excite field transmitters with 50 mA current capacity. Available at the back panel terminals 16 and 17.

CUSTOMIZED LINEARIZATION
The digital panel meter has five types of input for non-linear signals:
c.4-20, c.0-20, c.50, c.-20 and c.20
For using these signals, is necessary to adopt the Custom Linearization option. This feature combines the input signal to 30 user-defined line segments; setting two points for each segment, a start and end and the respective display values. Thus, the indication will have a non-linear behavior set by the input signal. The following figure shows an input signal associated with four-line segments (a, b, c, and d), causing that the resulting indication can be approximated to the ideal value (characteristic curve). The resulting indication is as best as the best straight segments are chosen.

Figure 2 – Custom linearization for a nonlinear signal

Note: The non-linear input signal shall have increasing pattern.

CONFIGURATION PROTECTION
As a safety measure, parameter changes can be prevented through a key combination performed at each level. With this protection, the parameters are still displayed but cannot be changed.To protect any level, just go to the level and press the and keys simultaneously for 3 seconds. To unlock the level, press the and keys for 3 seconds. The display will flash briefly to confirm locking or unlocking level. Inside the controller, the PROT key complements the protection function. In the OFF position, you can do and undo the protection of cycles. In the ON position, you cannot make changes. If there are protections cycles, these cannot be removed; if there is not, they cannot be promoted.

INSTALLATION

The digital panel meter is designed to be panel mounted. Remove the two plastic fixing clamps from the instrument, insert the device into the panel cut-out and slide firmly the fixing clamps from the rear against the panel.

INSTALLATION RECOMMENDATIONS

• The wires of the input signals must be installed separated from the output wires and power. If possible, in grounded conduits.
• he power supply for the instruments must be provided from an exclusive power source.
• In controlling and monitoring applications, possible consequences of any system failure must be considered in advance. The internal alarm relay does not warrant total protection.
• Use of RC FILTERS (47 R and 100 nF, serial) are highly recommended when driving solenoids, contactor coils or other inductive loads.

ELECTRICAL CONNECTIONS
The whole inner part can be removed without the need to make any disconnection.
Figure 3 shows the connection arrangement at the rear panel of the digital panel meter:

POWER CONNECTION
First check if the voltage required by the digital panel meter is compatible with the voltage of the instrument power supply. Provide adequate protection devices.

INPUT SIGNAL CONNECTION
It is important that they are very well connected, the sensor wires must be well fixed in the terminals of the rear panel.

LOAD CELL CONNECTION USING THE POWER SUPPLY

DIGITAL INPUT (DIG IN)
To use the Digital Input, a switch must be connected to respective terminals (dry contact), as shown in Figure 8:

ANALOG OUTPUT (4-20 MA OUTPUT)
The analog output may be 0-20 mA or 4-20 mA, selected in the configuration. The output is available at terminals 29 and 30, as requested in the purchase order.

OPERATION

For best results, this digital panel meter requires correct basic set of parameters or a definition for parameters displayed. It is necessary to define, for example Input type (0-20 mA, 4-20 mA, etc.), range display, alarm set point, alarm function etc. To make configuration easier, the parameters are divided in five cycles (or groups):

The work cycle has free access. All other cycles require a certain combination of keystrokes to be accessed. The combination is: and keys pressed simultaneously Once within a cycle, just press to move to the subsequent parameters of this cycle. At the end of each cycle the display will go back to the work cycle. At the desired parameter, just press the buttons or to promote the desired changes. These changes are saved into protected memory and given as valid when we move to the next parameter. After 25 seconds with no key pressed the digital panel meter will return to the Measurement screen at work cycle.

Note: It is recommended to disable/suspend the control whenever it is necessary to change the device settings.

PROGRAMMING THE DIGITAL PANEL METER

WORK CYCLE

Table 6 – Error messages
Other error messages shown by the digital panel meter must be reported to the manufacturer. Inform the serial number if this should occur. The serial number can be viewed at the display by pressing the key for about 3 seconds. The software version of the device can be viewed at the time it is powered. When not properly configured, the device may show false error messages, particularly those related to the input type selected.

SPECIAL RECOMMENDATIONS
Should the digital panel meter be repaired, some special handling should be taken. The device must be withdrawn from the housing and immediately placed in an anti-static wrap; protected from excessive heat and humidity.

INPUT CALIBRATION
When recalibration of some type of input is required, proceed as described below. You must use an appropriate framework for calibration, with equipment capable to provide the proper electrical signals.

• Set the digital panel meter for the input type to be calibrated (See Table 1).
• Program the desired upper and lower display limits (in.lol and in.kil) with limits on the type of configured input (See Table 1).
• Access the inLo( parameter and applied to input a signal corresponding to a known value and slightly above of the lower limit.
• Set the indicated value using the and keys to adjust the expected value for the applied signal.
• Access the inki( parameter and applied to input a signal corresponding to a known value and slightly below of the upper limit.
• Set the indicated value using the and keys to adjust the expected value for the applied signal.
• Exit the Calibration Cycle and verify that the calibration became adequate. Repeat c to f until no new adjustment is necessary.

PERFORMING AUTOMATIC CALIBRATION
To perform automatic calibration, the system must already be installed and configured with the input type and range already defined.

• Access the Auto Calibration Cycle and the A(all parameter.
• Put on the load cell the minimum reference weight and wait to stabilize.
• Adjust the A(all parameter to display the desired value.
• Press the key to save this value and advance to the parameter A(alk parameter.
• Put on the load cell the maximum reference weight and wait to stabilize.
• Adjust the parameter A(alk to display the desired value.
• Press key to save this value and terminate the procedure.
• At this time, the digital panel meter will show the weight on the load cell.

SERIAL COMMUNICATION

The digital panel meter can be supplied with an asynchronous RS485 digital communication interface for master-slave connection to a host computer (master). The digital panel meter always works as a slave. Communication is always initiated by the master, which sends a command to the slave address with which to communicate. The addressed slave takes over the line and sends the requested reply.
The digital panel meter accepts broadcast commands (addressed to all instruments of the network). In this type of command, the digital panel meter does not send any response N1500LC uses signals compatible with the RS485 standard allows 2-wire connection with a master and up to 31 digital panel meters (and can address up to 247) with bus topology. Maximum connection distance: 1000 meters. Digital panel meter off time: Maximum 2 ms after the last byte. Communication signals are electrically isolated from the rest of the device, with selectable Baud Rate between 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115600 bps.

• Number of data bits: 8 with no parity or even parity.
• Number of stop bits: 1
• Response start time: Maximum 100 ms after receiving the command.
• Protocol: MODBUS (RTU)

Signals from the RS485 interface are:
