Product description

Level and phase relay with pump protection against lack of water, phase failure or inverted sequence of motor phases.
Adjustable sensitivity, according to the liquid conductivity: 〔4 – 43〕KΩ


Applications

  • Total pump protection against lack of water and lack of phase to the motor or reverse phase sequence
  • Sensitivity adjustment 4 – 43 KΩ (depending on the conductivity of the immersion liquid)

Operation

Power the relay (green led on – A.1)

The relay is normally armed, disarmed whenever one of the following occurs:

Water level below probe “I” (lower) – only resets after water level rises above probe “S” (upper), green led “N.A.” – high level.

Missing or partial dropping of one of the “R”, “S” or “T” phases – resets automatically when the phases have the correct amplitudes.

Sequence of phases “R”, “S”, “T” inverted (phase change) – resets automatically when the correct sequence is reset.
