The Guardian angel for your pump
Control box is a control system for manual operation and automatic monitoring of 230V AC submersible pumps with external capacitor and three-phase submersible pumps and other three-phase centrifugal pumps.
The control box has the following functions:
- Switching on and off (right DOL)
- Overload protection
- Protection against phase failure (three-phase version)
- Protection against overvoltage
- Protection against short-circuit
- Dry running protection
The control box displays the following operating states:
- In action (ON)
- Water shortage (SB) - (automatic retry) - STAND BY
- Dry running (UL) - (switched off) - UNDERLOAD
- Overload (OL) - (switched off) - OVERLOAD
After eliminating the fault, can be switched on again manually. For this, the switch must first be switched to 0 and then I. The automatic monitoring will be reactivated.
The control box offers the following advantages:
- With one control box, motors can be monitored in three-phase from 5.5 to 10 HP. The setting of the rated current (nominal current) is carried out by a potentiometer inside the unit with the appropriate scale.
- In phase failure, overcurrent or overvoltage the control box switches off.
- The water level is monitored not by a prone and costly probe, but by changing the COS φ (power factor).
- In dry running, the system checks 4 times (after 10, 22, 45 and 90 min.) If the water level allows an automatic restart (SB). After that times, the motor is switched off (UL).
- Pressure switch, float switch, etc. can be connected to the control box. The connection is made via the terminals SW via a potential-free contact (opener).
- The command is transmitted by low voltage.
The control system is housed in a sturdy, non-conductive plastic housing IP44. The cable entries are splashproof.
