Quadro de Nível Digital para Águas Residuais

No need to use floats to protect and control electric pumps

Apresentação

- Plastic box 300x250x140 mm in gray ABS RAL7035 with hinge and transparent polycarbonate lid.
- Digital electronic relay for controlling and protecting the electric pump.
- Automatic, manual or off operation, controlled by a 3-position switch with protective cap.
- Operation of the audible alarm in automatic (AUT), test or off (0), by 3-position switch with protective cap, without interfering with the light alarm.
- Protection against short circuits through circuit breaker
- Connection for remote start command (C11-C12) (float or other)
- Connection for remote alarm command (C21-C22) (buoy or other)
- Protection against short circuits through circuit breaker
- Indication of engine on (green light)
- Indication of alarm on (sound alarm and red light)
- 4 cable glands, for passing the connection cables

Como Funciona

With the control circuit switch in the automatic position (AUT), whenever the automatic reset time (previously programmed) is reached or the start command (C11-C12) closes (LED “COM” of the PRObomba Relay), the pump turns on (green light and LED “OUT” of the PRObomba relay), switching off as soon as the relay detects a consumption lower than the minimum intensity limit “IL”, indicating on the display intermittently, “EIL” and the remaining time (hours) for check the automatic reset.

If, during operation, the PRObomba relay detects a consumption higher than the maximum intensity value “IH” for a period of time longer than 4 or 8 seconds, depending on the overload verified, the pump switches off, indicating on the Relay display “EIH” - error of overintensity. Manual resetting can be performed using the Relay “RST” reset key or using the control circuit switch, simply turning it off and on again.

Whenever, during operation, it is verified that the supply voltage is lower than the minimum parameter or higher than the maximum (factory preset values of 195V for the minimum voltage and 240V for the maximum) for more than 4 seconds, this is indicated on the Relay display PROpump every 4 seconds ”EUH” - overvoltage error or ”EUL” - undervoltage error).

With the control circuit switch in the manual position, the pump starts, regardless of the start command status.

Whenever the alarm command (C21-C22) closes or the maximum operating time "EO" (previously programmed) is reached, the alarm signal (red) and the audible alarm will be turned on, which can be turned off using the respective switch. .
