Novus N1040i Instruction Manual

N1040i Indicator
UNIVERSAL INDICATOR – INSTRUCTIONS MANUAL – V2.0x A
PRESENTATION
N1040i is a quite versatile process indicator. With a wide list of input
types - thermocouples, thermo-resistance, voltage and current – the
N1040i is capable of measuring the majority of the variables and
sensors encountered in industrial processes.
The configuration can be performed directly on the indicator or through
the USB interface. The NConfig software (free) is the configuration
management tool. Connected to the USB of a Windows computer, the
indicator is recognized as a serial communications port (COM) running
with a Modbus RTU protocol.
Through the USB interface, even if disconnected from the power
supply, the configuration performed in a piece of equipment can be can
be saved in a file and repeated in other pieces of equipment that
require the same configuration.
It also features various alarm functions, display offset, configuration
with password protection, serial communication, indication in degrees
Celsius (°C) or Fahrenheit (°F), among others.
FEATURES
SIGNAL INPUT (INPUT)
The input type to be used by the indicator is defined in the equipment

ALARMS
The 1040i can have none, one or two alarms. Each alarm present is
associated to one output with the same name (ALARM1 and ALARM2).
OUTPUT ALARM1 - Relay SPDT. Available in terminals 10, 11 and
12 of the indicator.
OUTPUT ALARM2 - Relay SPST-NA. Available in terminals 13 and
14 of the indicator.
The alarms can assume the functions described on Table 02.
Alarm off.
off
Alarm of the Absolute Minimum
Value. It triggers when the
value of the PV is below the
lo
value defined by the alarm
Setpoint (SPA1 or SPA2).
Alarm of the Absolute
Maximum Value. It triggers
when the value of the PV is
ki
above the value defined by the
alarm Setpoint.
Alarm of the Differential Value. In this function the
parameters "SPA1" and "SPA2" represent errors
(difference) between the PV and one reference value
ALrF.
dif
PV
ALrF–SPA1 ALrF ALrF+SPA1
SPA1 positive
Alarm of the Minimum Differential Value. It triggers when
the value of the PV is below the point defined by:
ALrF-SPA1 (using alarm 1 as an example).
difl
PV
ALrF – SPA1

SPA1 positive
Alarm of the Maximum Differential Value. It triggers when
the value of the PV is above the point defined by:
ALrF+SPA1 (using alarm 1 as an example).
difk
ALrF ALrF + SPA1
SPA1 positive
Alarms of the Sensor Break (Sensor Break Alarm). It is
activated when the Input presents problems such as
ierr
interrupted sensor, bad connection, etc.
