Motor controllers and measurement controllers are designed using the latest microprocessor technology to equip switchboards ALSU. Today it is the only commercially produced controller with graphical indicator in Russia. Wireless radio channel is used for communication with the motor controller.
The main features and advantages:
- Wireless radio communication for remote information read-out;
- High precision of measurements;
- Built-in intelligent well-control functions;
- Support of all switchboard designs, including soft start, VSD, down-hole control systems;
- Easy to operate: easy comprehensible graphical interface allows the
- operator easy to get any information;
- Versatility: you can easily upgrade it.
Main characteristics of motor controller:
Measuring:
- Supply-line voltage and input current;
- Power factor (cos j);
- Active power consumption and KVA capability;
- Line voltage on motor;
- Motor insulation resistance;
- Speed and sign of motor rotation.
Control:
- Direct and remote control;
- Manual and automatic mode.
Protection:
-
Protection from load problems (overload, underload, current unbalance);
-
Protection from power problems (overvoltage, undervoltage, voltage unbalance and wrong phase rotation);
-
Protection from operator error (excessive starts, tampering with set-points, start during spin, unauthorized startup after faults);
-
Flexible algorithms of protection control.
Liquid-crystal indicator:
- Graphic display - 320 x 240;
- Symbolic display - 4 x 20;
- Full-line, character-digital, graphic information;
- Menu control;
- External LED indicators of switchboard status.
Logs:
- Event log;
- Switchboard operation log.
