6.4.5 Alarm
buzzer
In this menu, the internal alarm buzzer of the HSK can be switched on or off. If the buzzer is activated,
an alarm is sounded in case of any fault occurrence.
6.4.6 Allowed T1 alarms
If during operation a T1 alarm frequently occurs (possible systematic fault), for example due to
overload (thermo contact T1 trips), the controller can be prevented from automatically restarting again
after the pumps have cooled down, upon reaching a certain number of fault alarms. The maximum
number of T1 thermo contact tripping can be set in this menu.
Should a T1 fault, since last being reset, reoccur more often than set in the menu, the controller will
stop and “nxT1” in shown in the display. n-1 is the number of T1-alarms. When this alarm mode is not
required, then a value 0 has to be entered.
The assigned pump is switched off after exceeding the set number of T1 alarms, until the reset button
has been pressed, only when:
The T1 fault in the "Alarm Auto Reset mask" has been set to 0 (automatic reset)
The nxT1 fault in the "Alarm Auto Reset mask" has been set to 1 (manual reset) have been entered.
6.4.7 High water alarm delay
If the high water level is exceeded or after the high water float switch trips, a delay time period can be
set which must elapse before a high water alarm is given. Short-term high water levels, therefore will
not lead to an alarm.
However, in the display, the high water message is immediately indicated as "hw". The waiting time
can be recognised by the red flashing LED. If the set delay time period has been exceeded, then the
LED shines continuously and "HW" is indicated.
