Page 4: Introduction
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. -

For further details see operation with rechargeable batteries. Attention: If the control unit should not be equipped with a main switch, then this control unit shall be made voltage free before opening of the cover! HSK_operating_manual_English_Ver3.doc HOMA Pump Technology... -
Page 7: Motor Protection
Apart from the above described automatic operation mode, each pump may be manually switched off or on by means of the operating keys or an external toggle switch. For details see Chapter 5.3 Depending on the features, the operation with only one pump is possible as well. HSK_operating_manual_English_Ver3.doc HOMA Pump Technology... -

In addition to the above described fault messages assigned to the pumps, the control unit monitors whether the following faults have occurred: • High water • Phase drop or phase sequence • faults in measuring technique (short circuit or wire breakage in the level sensor cable, inconsistent float switch status HSK_operating_manual_English_Ver3.doc HOMA Pump Technology... -
Page 9: Operation And Displays
LED signals the unit is ready for operation, a red LED indicates faults. The operation of the unit is effected by means of three keys ( , OK, ) (picture 2 below). Optionally, the control unit features additional keys or toggle switches for the 0-Hand-Automatic mode (picture 1 below). HSK_operating_manual_English_Ver3.doc HOMA Pump Technology... -

After the measuring method has been selected, it must be confirmed with the OK-key If a 4-20mA level sensor has been selected as measurement method, then after pressing the OK-key, the measuring range of the connected sensor must be additionally entered in cm. HSK_operating_manual_English_Ver3.doc HOMA Pump Technology... -
Page 16: Zero Adjustment
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. -
Page 17: Minimum Pressure
When the data is consistent, then the ? sign will not appear and the ↵-sign disappears after entering the last digit. When the control unit operates with float switches, then setpoints are not shown. When the control operates with float switches, the minimum pressure menu is not displayed. HSK_operating_manual_English_Ver3.doc HOMA Pump Technology... -

Entering a value of "9999" deactivates the pump rotation function, that is the control starts basically with pump 1 and pump 2 is always the peak load pump. Note: In the case of pump rotation function (1/1) and a value of "9999", pump 2 is never switched on automatically! HSK_operating_manual_English_Ver3.doc HOMA Pump Technology... -

Alarms In this menu behaviour of the control in case of faults is described. The menu has the following structure: Not in case of HSK controls featuring manual 0-Manual-Automatic switch(es) HSK_operating_manual_English_Ver3.doc HOMA Pump Technology... - Page 20 For example only bits 9...20 which belong to pump1, can be allocated to relay 2. The control unit HSK15 has 2 alarm relays, the control unit HSK25 has 3 alarm relays. In case of HSK15, the menu points for the 3rd alarm relay do not appear.

Page 22: Alarm Auto Reset
A recommendation for adjusting is given in the above table in the column "auto" ( x = automatic reset; n = no automatic reset; - no recommendation, depending on application). Security Note: The T2-alarm (thermo contact with higher tripping temperature) of controllers used in Ex-endangered areas should not be set to "Auto reset" .
