NOVUS Controller N1100 - Manual

NOVUS AUTOMATION 1/8
Controller N1100
UNIVERSAL PROCESS CONTROLLER – INSTRUCTIONS MANUAL V2.1x
PRESENTATION
The N1100 is a process controller incorporating a PID algorithm and
universal inputs (sensor and standard signals) and outputs (logical,
relay and analog outputs). It holds in one single instrument all de main
features that are needed for the vast majority of industrial processes.
SAFETY SUMMARY
The symbols below are used on the equipment and throughout this
document to draw the user’s attention to important operational and
safety information.
CAUTION or WARNING:
Read complete instructions prior
to installation and operation of the
unit.
CAUTION or WARNING:
Electrical Shock Hazard
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.
OVER-TEMPERATURE PROTECTION
When designing any control system it is essential to consider what
will happen if any part of the system should fail. In temperature
control applications the primary danger is one in which the heating
remains constantly on. In any application where physical injury or
destruction of equipment might occur, it is recommend to install an
independent protection equipment, with a separate temperature
sensor, to disable the heating circuit in case of overheating. Please
note that the alarm relays within the controller will not give protection
under all failure conditions.
INSTALLATION
Insert the unit into the panel cut-out and slide the mounting clamp
from the rear to a firm grip at the panel.
ELECTRICAL CONNECTIONS
All electrical connections are made to the screw terminals at the rear
of the controller. They accept wire sizes from 0.5 to 1.5 mm2 (16 to
22 AWG). The terminals should be tightened to a torque of 0.4 Nm
(3.5 lb in).
To minimize the pick-up of electrical noise, the low voltage DC
connections and the sensor input wiring should be routed away from
high-current power conductors. If this is impractical, use shielded
cables. In general, keep cable lengths to a minimum.
