NR9000 outputs
•
4 TRIAC Outputs to drive 3P valves (HOT valve and COOL valve).
Contact Rating 24-250V 4 A;
•
3 RELAY Outputs to drive 3 speed FAN (V1, V2, V3). Contact Rat
-
ing 24..250V 8 A;
•
2 Analogue Output 0-10V to drive proportional valves. It is possi
-
ble to use 0-10V outputs to drive a modulating FAN plus modu
-
lating valves in sequence (0-5/6-10);
•
2 Open Collector Outputs: OC1 and OC2. They have a max
-
imum load of 18mA and can be used to drive 12Vdc relays
whose maximum power is 220mW and winding resistance >=
640Ohm (ref. Controlli relay module mod. DGSRMV);
•
OC1 output follows the ON/OFF input and it can be used,
through an external relay, to enable electrical loads. If the
local operation mode is enabled (through controller pass-
word) OC1 follows the input DI2 (override turn off), so if DI2
is open, OC1 is ON too, instead if DI2 input is closed, OC1 is
OFF too. If the local operation mode is disabled, OC1 fol-
lows the value set at 9011 ModBus address;
•
OC2 output is used to enable auxiliary functions described
in the “Controller functions” paragraph. If the temperature
sensor S3 is present, the ON/OFF auxiliary loop which con-
trols OC2 will be automatically enabled; otherwise it is pos-
sible to enable the electrical coil in emergency (through
controller password) which controls OC2. If the sensor S3
is not present, OC2 follows the value set at 9013 ModBus
address;
•
1 Bus to connect remote terminal NR9000-RT;
•
1 Bus Modbus to connect supervisor system;
•
1 Bus Link to connect IO expansion;
•
1 communication connector with infrared receiver module
NR9000-RX (through a 80cm flat cable)
Directives and Standards
Standard CEI EN 60730-1 for EMC directive.
Standard CEI EN 60730-1 and CEI EN 60730-2-9 for LVD directive.
INSTALLATION
Installation of NR9000 controller
NR9000 are suitable for mounting on a DIN rail with a quick coupling.
Connections shall be in compliance with existing rules and using max
2,5mm
2
cross section wires for J1 and J2 terminals and 1,5mm
2
cross
section wires for J3 and J4.
To use wire terminals on power supply wires follow the instructions in
order to prevent accidental contacts between cables at different
voltages in case of wrong installation.
The main power is fully isolated but we suggest to install a protection
device compliant to existing national rules with a 125mA intervention
threshold and a minimum 3mm contact opening. The device is not
supplied with the product.
To use the infrared remote control (NR9000-TC) it is necessary to con-
nect NR9000 to the receiver module NR9000-RX through the cable
supplied with the controller.
The connection port of the receiver module is placed on the upper
side of the NR9000 controller. The receiver can be installed in the
range of the infrared remote control through the double-side tape
supplied with the receiver. The infrared remote control NR9000TC is
powered by 2 AAA batteries (included) and it is equipped with a
support for wall mounting (further information on page 17).
Installation of NR9000-RT remote sensor
NR9000-RT is suitable for flush mounting in standard box 503E or for
wall mounting on the basis of the model. The supporting frame is
compatible with BTicino cover plates Livinglight (square cover) or
Living International (round cover) otherwise with Vimar Plana cover
plates modifying the supplied supporting frame as shown in the fol-
lowing figure.
Using a screwdiver
press the snap and
push down.
