Controller ELEKTON-09 for VSD ELEKTON-05

Purpose and application

Controller ELEKTON-09 for switchboard ELEKTON-05 is intended for rotating speed variation, optimization of work and protection of generally marketed electric motors.
Functionally and constructively the controller is divided into 2 blocks: frequency converter control unit Elekton-09.2 and interface module Elekton-09.1.
Controller is a programmable device, it makes possible to control work process with changing settings, to store in memory events log, to obtain data as graphic or digital mode.

Functional capabilities

Controller provides the folloving functions:

• regulation of the electric motor’s rotation speed from built-in control panel;
• switchboard’s autorestart after the shutdown troubleshooting service;
• smooth electric motor’s acceleration with preset rate;
• electric motor rotation directionreversal;
• programmable frequency correction bursts to provide automatic putting the well into operating duty;
• electric motor gradual braking when voltage limit value increasing in dc link;
• automatic maintenance of the technological parameter value (pressure, temperature, level and so on) from 2 of the 8 analog inputs;
• data communication via one port RS-232 and two ports RS-485, connection to the telemechanics system for remote control and on-line control – start-up, shutdown, setpoints change;
• operation under field decay conditions if speeds of rotation exceed rated;
• possibility to vary characteristic U/F (for different types of loading) without switchboard’s shutdown;
• writing operating parameters of the switchboard (mains voltage, current, output frequency and so on) into controller memory and their fast view on the controller display directly;
• fixation in event log of the time of main supply switching off and on;
• setpoints changing registration in event log with indication of the data and time of the parameter’s value changing before and after, as well as the way of changing – remotely or by operator;
• recording in event log the course inhibiting the switchboard start;
• recording into event log the date and time of setpoints changing with indication of previous and new values;
• record into memory the meanings of the mains voltage values within adjustable periods, if it doesn’t allow the switchboard switching on;
• showing on controller display the protection name, which caused the switching off, with indication of remaining period of time (in minutes and seconds) before ESP motor switching off;
• automatic frequency changing up to preset value during preset period of time;
• 2 modes of wedging of ESP rotary unit:
  1. specified number of blows by increased voltage with specified output current frequency, in forward direction;
  2. specified number of blows by increased voltage with specified output current frequency, in different directions – «swinging».
• programming of analog inputs in any of 3 standards: 0-4 V, 0-10 V, 4-20 mA;
• password setting for exception of an unauthorized access of the switch- board programming, 8 users password indentification;
• possibility of frequency convertor`s operation in modes of pulse-width and 6-pulse modulations.
