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.

Controller N1100 EVENT ALARM PROBLEMS WITH THE CONTROLLER This function makes possible to program the activation of alarms in specific segments of a program. For such, alarms must have their function set as “rS rS “ and be programmed in “ PE1“ PE1 to “ PE7“ PE7 according to Table 6. The number programmed in the event prompt defines the alarms to be activated. To configure and execute a ramp and soak program: • • • • • Program the tolerance value, SV, time and event.

Controller N1100 SERIAL COMMUNICATION The indicator can be supplied with an asynchronous RS-485 digital communication interface for master-slave connection to a host computer (master). The indicator works as a slave only and all commands are started by the computer which sends a request to the slave address. The addressed unit sends back the requested reply. Broadcast commands (addressed to all indicator units in a multidrop network) are accepted but no reply is sent back in this case. ...................
