NOVUS AUTOMATION 1/5
N1500G
UNIVERSAL INDICATOR - OPERATING MANUAL
1. PRESENTATION
N1500G is a universal process indicator which accepts a large
variety of input signals and sensors.
A five-digit LED display shows measured value and all programming
parameters.
Instrument configuration is achieved from the keyboard, without any
hardware change.
The user should read this manual thoroughly before using the
instrument. It is a fine electronic device and should be used
accordingly for best results.
Some of the features of the basic version are:
•
Universal input: Pt100, thermocouples, 4-20 mA, 0-50 mV and 0-5
Vdc
•
24Vdc power supply for remote transmitters excitation
•
Maximum and minimum memory
•
Digital input with Hold Peak Tare and hold function
•
Process Variable retransmission in 0-20 mA or 4-20 mA
•
RS485 MODBUS RTU serial communication
Display: Shows process variable (PV) and the programming
prompts.
ALM1 and ALM2: show alarm status.
INDEX key - This key is used to access the programming
menu and prompts.
BACK key - This key is used to go back to the previously
reached prompt in the menu cycle.
UP / MAX key and DOWN / MIN - Used to increase
and decrease parameters values, these keys are also used
to display maximum and minimum values stored in memory..
Special FUNCTION key - This special function key is used
for pre-programmed functions as explained in the SPECIAL
FUNCTION KEY section of this manual.
2. PROCESS VARIABLE INPUT - PV
The Process Variable input type should be keyboard programmed by
the user according to the codes shown on table 1 (refer to INPUT
TYPE parameter "in.typ
in.typ in.typ in.typ").
All input types are factory calibrated and no additional calibration is
required.
Thermocouples are calibrated to NBS standards. RTD’s are
calibrated to DIN 43760 (
α
=0.00385).

Table 2 - Alarm functions
3.1. ALARM FUNCTIONS
The alarms can set to operate in six different functions: Sensor
break, Low Alarm, High Alarm, Differential Low, Differential High or
Differential (Band). These functions are shown in table 2 and
described as follows
3.1.1. Sensor break
The alarm will go ON whenever the sensor breaks or is badly
connected.
3.1.2. Low alarm
The alarm relay will go ON whenever the measured value is below
the alarm set point.
