PUMP EQUIPMENT

The control cabinet is designed to control and protect pumps with standard asynchronous AC motors with a squirrel-cage rotor in accordance with the control signals and the required operation algorithm of the units.

The control cabinet provides:

• Comprehensive protection of supply circuits and electric motors
• Choice of control modes: automatic or manual
• Automatic control of electric motors by signals from float switches, electrodes or other external relay or analog control signals
• • Automatic shutdown of electric motors in the presence of an external signal (thermal relay or other relay contact) and automatic activation in its absence
• Automatic shutdown of electric motors in case of a short circuit or operation of a thermal relay built into the motor protection circuit breaker
• Automatic shutdown of electric motors in case of loss of one of the phases
• Visual display of a working or emergency condition of each electric motor
• Remote transmission of an alarm signal for each electric motor
• ( potential-free contacts)
• It is possible to select the number of main/standby pumps using the logic module settings inside the cabinet
• Periodic change of functions of electric motors at specified intervals of operation in order to equalize the resource (only for cabinets for two or more electric motors)
• Smooth start and stop of pumps for a series of cabinets with a soft starter Trial run of each pump during downtime to protect against jamming (on request)
• Output of information about the current state of the pump to the control room
• Protection of pumps from running without water by connecting a dry running sensor
• (pressure switch, level sensor, etc.)
• Dispatching: "Accident" of each electric motor

Facilitate troubleshooting by constantly monitoring the status of the sensors.
