NOVUS AUTOMATION 1/4
Controlador N960
CONTROLADOR DE TEMPERATURA - MANUAL DE INSTRUÇÕES – V3.0x E
INSTALLATION
The controller must be installed in panels with square slots. To fix it,
insert the controller in the panel slot through the front side and fix the
clamps on the controller body through the rear end of the panel.
Press the clamps tightly to fix the controller on the panel.
You can withdraw the internal part of the device from its case through
the panel front side, it is not necessary to remove the case, the
clamps or connections. Pull firmly the controller from the front panel
and it will leave the case.

EMC: EN61326-1:1997 and EN61326-1/A1:1998
Emission: CISPR11/EN55011
Immunity: EN61000-4-2, EN61000-4-3, EN61000-4-4, EN61000-
4-5, EN61000-4-6, EN61000-4-8 and EN61000-4-11
Safety: EN61010-1:1993 and EN61010-1/A2:1995 (UL file
E300526)
Accuracy: 0.20 % of the maximum range 1 °C for Pt100
0.25 % of the maximum range 1 °C for Thermocouple
The thermocouples must be connected to the 11 and 12 pins,
observing polarity. A compensation or extension cable is required.
Pt100 sensors must be 3-wire connected to terminals 10, 11 and 12
as Fig. 1 shows. For an adequate cable resistance compensation, all
the conductors must have the same electrical resistance. If the Pt100
is a 4-wire sensor, leave one disconnected by the controller. For 2-
wire Pt100, use a jumper in the 10 and 11 terminals of the controller
(in this case, there is no auto compensation of the cables length, 1
°C is added to each 0.4 of the total cable resistance).
Table 1 shows the different types of temperature sensor the
controller can accept and the keypad code for their selection.

POWER SUPPLY
Power is supplied through the terminals 13 and 14. Check the voltage
written on the device box.
ELECTRICAL CONNECTIONS

CONTROL OUTPUTS AND ALARM
There are THREE outputs for process control or alarm.
O/I 1: - Relay output, SPDT 3 A / 250 Vac (3 A / 30 Vdc);
O/I 2: - Relay output, SPDT 3 A / 250 Vac (3 A / 30 Vdc);
O/I 5: - Output current 0-20 mA / 4-20 mA; 500 R max;
- Digital Pulse Output; 12 V / 25 mA;
The output features (control or alarm) are user-defined at the
controller settings. The I/O output is able to provide a current signal
of 0-20 mA or 4-20 mA and a voltage pulse digital signal with no
changes in the controller hardware required.
Different outputs may be set up to perform the same function. The
outputs are automatically turned off whenever the controller
displays the message “ER1”, which accounts for a device fault or
disconnection.
