Table 2 - Alar functions
4.1. ALARM FUNCTIONS
The alar s can set to operate in six different functions: Sensor
break, Low Alar , High Alar , Differential Low, Differential High or
Differential (Band). These functions are shown in Table 2 and
described as follows.
4.1.1. Sensor break
The alar will go ON whenever the sensor breaks or is badly
connected.
4.1.2. Low alarm
The alar relay will go ON whenever the easured value is below
the alar set point.
4.1.3. High alarm
The alar relay will be ON whenever the easured value is above
the alar set point.
4.1.4. Differential (Band)
For differential alar 2 para eters ust be set: Differential Alar
Reference value (ALrEF
ALrEFALrEF
ALrEF) or alar setpoint and Alar Deviation
(Band).
For a positive deviation the alar will switch on whenever the
easured value is out of the band defined as:
(ALrEF
ALrEFALrEF
ALrEF - Deviation) and (ALrEF
ALrEFALrEF
ALrEF + Deviation)
For a negative deviation the alar will be switched on whenever the
easured value is within the band defined above.
4.1.5. Differential Low
The alar relay will be ON whenever the easured value is below
the band defined as:
(ALrEF
ALrEFALrEF
ALrEF - Deviation)
4.1.6. Differential High
Alar relay will be ON when the easured value is above the band
defined as:
(ALrEF
ALrEFALrEF
ALrEF + Deviation)
4.2. ALARM TIMER
The alar s can be progra ed to have ti er functions where the
user can set a delayed alar action, just one pulse in an alar
event, or an oscillator function with sequential pulses.
Table 3 shows these advanced functions. Ti es T1 and T2 can be
progra ed fro 0 to 6500 seconds (refer to ite 8.2). Set 0 (zero)
at the T1 and T2 pro pt for a nor al non-ti er alar operation.
The LEDs alar indicators will go ON whenever there is an alar
condition regardless of the present alar status which ay be
te porarily off because of ti er action.

4.3. ALARM INITIAL BLOCKING
The initial blocking option inhibits the alar fro being recognized if
an alar condition is present when the controller is first energized.
The alar will actuate only after the occurrence of a non alar
condition followed by a new occurrence for the alar .
The initial blocking is disabled for the sensor break alar function.
5. SPECIAL FUNCTIONS
5.1. MAXIMUM AND MINIMUM
The indicator e orizes the easured axi u and ini u
values (peak and valley). These two values are shown by pressing
either the or key. Pressing both keys si ultaneously will
clear the e ory for a new peak and valley detection.
5.2. SPECIAL FUNCTION KEY AND DIGITAL INPUT
The F key and the optional digital input can execute special functions
according to the user selection.
These functions can be chosen independently to the F key or to the
digital input. A closed contact or a short circuit at ter inals 12 and 13
is recognized as activating the digital input.
The special functions for the F key and for the digital input are
explained as follows.
5.2.1. Hold
The hold function freezes the easured value in the display. Each
touch at the F key or closing the digital input alternates fro hold to
nor al ode.
Whenever the indicator is in the hold ode a “HoL
HoLHoL
HoL ” essage is
briefly displayed to show the operator that the displayed value is the
frozen value and not the present reading.
5.2.2. Peak Hold
The indicator turns auto atically to Peak Hold ode whenever the F
key or the digital input are progra ed for “P
PP
PHoL
HoLHoL
HoL ”
This operation ode akes the indicator display only the axi u
reading value fro the ti e the key was pressed of the digital input
was activated.
Each activation of the F key or digital input triggers a new Peak Hold
cycle and the display resets with a new peak value.
5.2.3. rESEt
rESEtrESEt
rESEt (clears axi u and ini u )
This function works the sa e way as the and keys
pressed si ultaneously, as explained in the 5.1 section.
If this “rESEt
rESEtrESEt
rESEt” function is progra ed, for every touch of the F key
or activation of the digital input the e ory will be cleared and a new
cycle of axi u and ini u will start.
5.2.4. AL.oFF
AL.oFFAL.oFF
AL.oFF - Alarm blocking
This function allows the user to block or inhibit the alar relays by
pressing the F key or by activating the digital input. Each touch of
the key or activation of the digital input will alternate the function fro
ON to OFF and vice-versa.

Indicator N1500G
NOVUS AUTOMATION 3/6
If an alar situation occurs, the respective alar status LEDs in the
front panel will light regardless of the relay alar blocking status.
5.2.5. Tare
This function is used to zero the display. The tare residual values is
subtracted or added to the total easured value. This function is
generally used with load cells and strain gauges and applies to linear
4-20 A, 0-50 V and 0-5 V inputs.
5.3. PROCESS VARIABLE RETRANSMISSION
As an option, the indicator can be supplied with an isolated 0-20 A
or 4-20 A analog output for Process Variable (PV) retrans ission.
The PV values which define the range of the 0-20 A or 4-20 A
retrans ission can be progra ed by the user in the high and low
indication limits.
Note – PV retrans ission does not take an action of the special Hold
and Peak Hold functions.
5.4. CUSTOMIZED LINEARIZATION
The indicator features three types of input signals that allow for
custo linearization, this is, the user can configure the device in
order to obtain accurate indications for electrical signals with non-
linear and ever increasing characteristics. The three types of input
signal are: c.0
c.0c.0

creates the Custo Linearization Cycle.
The input signal ust be divided in seg ents ( axi u 19), defined
in order to ini ize the error between the input signal and the
corresponding indication. In the Custo Linearization cycle the user
finds the para eterinp.01

para eters ust be set before these Custo Linearization settings.
In this ode the sa pling rate is 4 easure ents per second.
6. INSTALLATION
6.1. PANEL ASSEMBLY
The indicator is co posed of two parts: the fixing base and the front
part with ain circuits. The base ust be re oved fro the front and
fixed onto a wall by eans of four designed holes as shown in
Figure 1.

4X 4mm
3X 12mm
Figure 1 - Mounting the indicator in the panel cut-out.
The front part is only attached to the fixing base after all electrical
wire connections are done.
6.2. ELECTRICAL CONNECTIONS
The internal electronics can be re oved fro the front panel without
any cable disasse bly. The input signals and power connections are
shown in Figure 2.
Figure 2 - Back panel ter inals
Note: The left side of the indicator is re ovable. It is fixed there
a label containing the connections.
6.2.1. Recommendations for Installation
• Input signal wires should be laid out away fro power lines and
preferably inside grounded conduits.
• Instru ent ains (line) supply should be suitable for this purpose
and should not be shared.
• In controlling and onitoring applications, possible consequences
of any syste failure ust be considered in advance. The internal
alar relay does not warrant total protection.
• RC filters (47 Ω and 100 nF) are highly reco ended for valve
and contactor coils, etc.
6.2.2. Sensor or input signal connection
These connections should be properly done and ter inals ust be
well tightened. Ther ocouples ust be installed with proper
extension or co pensation cables.
Pt100 RTDs ust be 3-wire connected and the wires connected
should have the sa e electrical resistance (sa e wire gauge) for
correct cable length co pensation. Four-wire RTDs can be
connected by disconnecting the fourth wire. Two-wire RTDs can be
connected by shortening ter inals 7 and 8 and connecting the Pt100
to ter inals 8 and 9.
7. OPERATION
For best results this indicator requires correct setting of para eters
as input type (T/C, Pt100, 4-20 A, etc), alar s actuation point,
alar function, etc.
These para eters are divided in five levels or groups of para eters
which we will refer to as CYCLES.

9. DIGITAL COMMUNICATION
The indicator can be supplied with an asynchronous RS-485 digital
co unication interface for aster-slave connection to a host
co puter ( aster).
The indicator works as a slave only and all co ands are started by
the co puter which sends a request to the slave address. The
addressed unit processes the co and and sends back the answer.
Broadcast co ands (addressed to all indicator units in a ultidrop
network) are accepted but no response is generated.
9.1. CHARACTERISTICS
-RS-485 co patibility with two-wire bus fro the host to up to 31
slaves in a ultidrop network topology.
-Up to 247 units can be addressed by the MODBUS RTU protocol.
-Maxi u network distance: 1200 .
-Ti e of indicator disconnection: Maxi u of 2 s after the
delivery of the last byte.
-Co unication signals electrically isolated fro the rest of the
instru ent.
-Baud rate: 1200, 2400, 4800, 9600, 19200, 38400 or 57600 bps.
-Nu ber of data bits: 8, without parity or even parity
-Nu ber of stop bits: 1
-Ti e to start response trans ission: 100 s axi u delay after
acknowledging the co and.
-Protocol: MODBUS (RTU)
9.2. RS485 INTERFACE: ELECTRICAL CONNECTION
The RS-485 signals are: D1 = D: Bidirectional data line
D0 =
D:
Inverted bidirectional data line
C = GND: Optional connection. I proves
co unication perfor ance for
long cable runs.
REDUCED REGISTERS TABLE FOR SERIAL
COMMUNICATION
COMMUNICATION PROTOCOL
The MOSBUS RTU slave is i ple ented. All configurable
para eters can be accessed for reading or writing through the
co unication port. Broadcast co ands are supported as well
(address 0).
The available Modbus co ands are:
01 – Read Coils 05 – Write Single Coil
03 - Read Holding Register 06 - Write Single Register
HOLDING REGISTER TABLE
Follows a description of the usual co unication registers. For full
docu entation download the Registers Table for Serial
Communication in the N1500G section of our website –
