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 the built manual motor starters and the pump motor thermo contacts  as well as phase 

sequence and phase drop. Other features include, integrated current measurement, hour meter and 

cycle counter as well as a flexible alarm messaging system. 

The HSK pump controller is available in various configurations. This manual describes the control 

functions in detail.  

Please note! All of the functions described in this manual may not be available on every pump control 

as this will depend on the configuration selected. The HSK15 control unit in particular, does not have 

all of the functions and features of the HSK25 pump control. 

2 Safety 

guidelines 

This operating manual exclusively describes the control unit section. It contains important references  

and warnings, and therefore should be read by the installer as well as by the relevant operator before 

installing and operating the unit. 

Note!

 Not only should the general safety references mentioned in this “Safety guidelines” section be 

observed, but also any special safety references referred to in the other sections of the manual. 

2.1 

Marking of guidelines in the operating manual 

Safety references contained in this operating manual, which can cause personal danger on failure to 

observe them, are  

 
   
 
 
 

  

2.2 To be observed 

The description and instructions in this operating manual relate to the HSK controls. 

This operating manual does not take into account either all possible design details, styles or all 

possible coincidences and incidents, which may occur during mounting, operation and maintenance. 

The CPS modular pump control is to be used by professionally trained personnel (see EN 50 110-1). 

 

Warning against electric voltage is marked with this general danger symbol.
