The HMS Control L3 panels are intended for control and 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.
Applicable sensors:
Pressure relay;
Electric-contact manometer;
Floating sensors of level;
Electrode sensors of level.
Features:
Pump switching off at overload/underload (protection from «dry running», without sensors)
Water level control in a borehole using the «dry running» sensor
Control of mains voltage
Phase rotation, break, distortion
Resistance check of the motor winding before a pump start
Motor winding temperature control (optional, sensor is required)
Fault control of connected sensors
Pump shutdown in case of external accident signal
Short circuit protection
Surge voltage protection
User interface panel

Available options:
Н – overvoltage protection: the panel is switched off the mainline
М – surge protection (lightning and connection surges)
Р – switch-disconnector at the panel cover
Т – motor winding temperature sensor (PT100 /PTC)
* Approximate values are given. Some pumping units may have different rated current values at given power. Please refer the manual.
