SAFETY ALERTS

The symbols below are used on the equipment and throughout this
manual to draw the user´s attention to essential information related to
the equipment safety and operation.
CAUTION:
Read the manual thoroughly
before installing and operating
the instrument.
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 instrument is used in a manner not
specified by the manufacturer, the protection provided by the
equipment may be impaired.

PRESENTATION

N1540 is a quite versatile process digital panel meter. With a wide list
of input types − thermocouples, thermo-resistance, voltage and current
– the N1540 can measure most of the variables and sensors
encountered in industrial processes.
It contains two alarms (six functions), sensor offset, configuration of
parameters protected by password, serial communication, indication in
degrees Celsius (°C) or Fahrenheit (°F), among others.
Configuration can be performed either directly on the digital panel
meter or via the USB interface once QuickTune software has been
installed on the computer to be used. Once connected to USB, the
device will be recognized as a serial communication (COM) port
operating with Modbus RTU protocol.
Through the USB interface, even if disconnected from the power
supply, the configuration performed in a piece of equipment can be
saved in a file and repeated in other pieces of equipment that require
the same configuration.

ALARMS

The digital panel meter has two alarms. Each alarm is associated with
an output with the same name: AM1 and ALM2.
The alarms can assume the functions described on Table 02.
Alarm off.
off
Alarm of the absolute minimum
value. It triggers when the PV
value is below the value
lo
defined by the alarm Setpoint
(SPA1 or SPA2).
Alarm of the
maximum value. It triggers
when the PV value is above
ki
the value defined by the alarm
Setpoint.
Alarm of the differential value. In this function, the SPA1
and SPA2 parameters 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 PV value is below the point defined by:
ALrF-SPA1 (using alarm 1 as an example).
