NOVUS N320 - Manual

ELECTRICAL WIRING
It is important to follow the recommendations below:
Signal wires should be installed in grounded conduits and away from power or
contactor wires.
The instrument should have its own power supply wires that should not be
shared with electrical motors, coils, contactors, etc.
Installing RC filters (47 R and 100 nF, series combination) is strongly
recommended at contactor coils or any other inductors.
System failure should always be taken into account when designing a control
panel to avoid irreversible damage to equipment or people.

TEMPERATURE METER
N320
OPERATING MANUAL - V1.8x
Man 5001217
The N320 is a temperature meter that provides you in the frontal display the
measured temperature of the sensor connected to its terminals. The temperature
sensors available are NTC Thermistor, Pt100, Pt1000 and J, K, T type
thermocouple, with offset correction capability.
The features of a particular model (input sensor type, sensor range, mains supply,
etc) are identified by the label placed on the thermometer body.
SPECIFICATIONS
INPUT SENSOR: The input sensor type can be chosen form the 4 options below
(specified when placing the order):

NTC Thermistor, 10 k @ 25 °C; range: –50 to 120 °C (-58 to 248 °F);
Accuracy: 1.0 °C (1.1 °F), with original sensor;
Sensor interchangeability: 1 °C (1.35 °F). This error can be compensated by
the offset parameter in the temperature meter.
 Pt100 ( = 385); Range: –50 to 300 °C (-58 to 572 °F);
Accuracy: 0.7 °C (1.3 °F); IEC-751.
 Pt1000 ( = 385); Range: –200 to 530 °C (-328 to 986 °F); Accuracy: 0.7 °C (1.3° F);
 J, K or T thermocouple (IEC-584):

Type J: Range: 0 to 600 °C (32 to 1112 °F); Accuracy: 3 °C (5.4 °F);
 Type K: Range: -50 to 1000 °C (-58 to 1832 °F); Accuracy: 3 °C (5.4 °F);
 Type T: Range: -50 to 400 °C (-58 to 752 °F); Accuracy: 3 °C (5.4 °F);
Note: In the temperature meter with NTC input, a 3 m-sensor cable is bundled
with the instrument. The cable can be extended up to 200 m.
