4. Стр. 4 1 Introduction

   HOMA HSK is a modular pump control for up to two pumps, which has specifically been designed for use in the wastewater sector. The pump control measures and monitors the level of the medium and depending on the level, starts or stops either one or two pumps. In addition, the HSK continually monitors…

   When the controller already features factory-installed isolating amplifiers and/or electrical (zener) barriers, then the permission documents and operating instructions are included with the switchgear and they must be adhered to. Particular attention to applicable regulations concerning wiring is…

   Current measurement and ampere meter function The control unit measures the current for each pump in a motor phase. The current is indicated in the display. Additionally, the current is monitored and thus an electronic motor overload relay is simulated. Undercurrent monitoring is also carried out.…

   loss of control voltage • rechargeable battery voltage too low • leakage monitoring • additional "AUX" alarm of each pump • "external" fault (only HSK25 in case of continuous level measurement) Faults are signalled by means of a red LED, an internal buzzer, or with up to three voltage free alarm…

10. Стр. 10 Operating the manual motor starters, RCD's or the main switch is effected by using the knobs of the

    respective device. 4.5 Rechargeable battery operation The control unit can be operated with a rechargeable battery so that in case of a 230V~ control voltage loss the unit will continue to operate. The battery is recharged by the unit and can be used together with the potential free SPDT contacts of…

16. Стр. 16 For example, for a HOMA LLS with measuring range of 2,5m - the value of 0250cm is entered

    Important information: If values for the measuring range < 0100cm are entered, then the control inserts the minimum value of 100cm , in case of values >1000cm, the control inserts the maximum value of 1000cm. If “3x float switches” has been selected and the unit is subsequently switched to a single…

17. Стр. 17 Note: When the filter is active, the level indication can be so inert that the measured

    level may deviate greatly from the level in the shaft. The shaft may have already been emptied, the measured value, however, still indicates a level above the cut-out setpoints and the pump may possibly run dry. Therefore, pump capacity, setpoints, and filter values must be well in balance with each…
