Liquid Level Controller – LV1

R430.08

Level control unit of conductive liquids which can be configured for FILLING or EMPTYING. The unit can be used as a two probe system for alarm purposes or a three probe system to control HIGH and LOW levels of a reservoir. Up to four LV1 can be utilized in the same reservoir by connecting all commons (pin7). The sensitivity of the unit can also be adjusted.

 

Features:

 

  • Fail-safe control feature
  • Rear DIP switch selectable FILLING/EMPTYING
  • Adjustable sensitivity
  • Modulated AC probe signal to prevent electrolytic corrosion
  • Low voltage probe signal
  • Power supply ON and Relay ON LEDs
  • Output 10 A SPOT

Pump Seal Protection – PSP1

Microprocessor based monitoring relay to measure moisture in a submersible pump. Due to the advanced design of the unit a high accuracy and safety is achieved. Response delay are incorporated to prevent nuisance tripping. The unit energises on application of supply. If the current through the probes is more than 20uA or the resistance is smaller than 10 Mohm, the relay will de-energise after 10 sec. The relay will energise if the current is less than 15uA and the resistance is more than 1.4Mohm.

 
Features:
 
  • Microprocessor based design
  • High accuracy analogue converter
  • Repeatable deviation: <0.2%
  • Power supply ON and Relay ON LEDs

Power Supply Unit – PSU/10

Microprocessor based pump protection relay capable of protecting a submersible pump against all major power line faults. The unit calibrates itself under normal running conditions and stores these parameters in non-volatile memory. The unit also incorporates a reset delay for under current situations to enable the borehole to replenish itself. In an over current situation the unit will retry three times to prevent permanent tripping with temporary blockages.

 
Features:
 
  • Overload Protection
  • Short-circuit Protection
  • Over Temperature shut down
  • Stable supply with low ripple factor
  • Power supply ON LED
