HMS Control L4 series Panel for a single pump remote control
Application
The HMS Control L4 panels are intended for protection of the electric motors driving single borehole, submersibe, or surface installation pump (overhung, double suction, etc.). in the following applications:
Water supply form boreholes, wells;
Level control in storage tanks;
Pressure maintenance in water supply systems;
Dewatering systems, drainage of reservoirs, open pits, etc.
Features:
Quick mode selection and simple adjustment («Quick start»);
Applicable sensors types: contact, electrode, analog 4..20 / 0..20 mА;
A wide range of panels for up to 132 kW electric motors (panels over 132 kW are optionally available);
Pump compartment burglar alarm;
RS-485/RS-232 interface, Modbus RTU protocol;
GSM/GPRS modem or 433 MHz radio band data transmission (option);
Pump control and status reports by Short Messaging Service (SMS) available as option.
Protection:
Short circuit
Electric motor underload / overload;
Dry running, including sensor-free protection;
Motor winding insulation pre-start check;
Phase sequence, phase break, phase distortion;
Number of pump starts per hour;
Voltage surge/ lightning protection (option).
Parametrs indication:
Average current and voltage on each phase;
Sensors status;
Pressure in discharge pipeline or water level in storage tank (analog sensor is required);
Motor winding temperature (sensor is required);
Alarm log (with time and equipment status recording);
Number of starts and total operation time.
All parameters can be transmitted via RS-485 (RS-232), Modbus RTU protocol.
Control modes:
Manual;
Automatic by commands from pressure/level sensor or timer;
Remote by RS-485/RS-232 or digital inputs.
