UNIVERSAL PROCESS CONTROLLER – INSTRUCTIONS MANUAL – V2.1x C

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.

INTRODUCTION

The N3000 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.

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.

OUTPUTS, ALARMS AND DIGITAL INPUTS CONFIGURATION
The controller input/output channels can assume multiple functions,

depending on configuration: control output, alarm output, digital

output, digital input, and PV or SV analog retransmission. These

channels are identified as I/O1, I/O2, I/O3, I/O4, I/O 5 and I/O6.
The basic controller model comes loaded with:
• I/O1 and I/O2 - SPDT relay output;
• I/O3 and I/O4 – SPST relay output;
• I/O5 - analog output (0-20 or 4-20 mA), pulse 10 V max, digital I/O;
• I/O6 – Digital Input;
The function code of each I/O can be selected among the options on

Table 2. Only valid function codes are displayed for each I/O (for

example, I/O1, which is a relay, can be configured with functions 0 to

5 only; on the other hand, I/05 can perform all 16 functions).
The description for the functions follows:
CODE 0 - No function. The I/O channel programmed with code 0

will not be used by the controller. It is available to be used by serial

communication as digital output.

CODES 1 to 4 - Alarm output - Available for all I/O channels

(except I/O6). The selected channel can be used as output to

Alarms 1 to 4.

CODE 6 - Digital input - Standard for I/O5 and I/O6.

Closed: Manual control
Opened: Automatic control
