Level Sensor And Float Switch Connection - Homa HSK15 Operating Manual

-- Stand-by --
ACC 09.1V PW 00.0V
(in the second line the measured rechargeable battery voltage and the internal control voltage are
displayed).
The control shall continue to operate only when the rechargeable battery voltage or the control voltage
have reached their rated values again.
It takes approx. 50h until the rechargeable battery is charged.
A lead gel battery with a rated voltage of 12V /1,2Ah is used.
It is not allowed to use any other type of batteries, because the recharging circuit has been laid out for
lead gel batteries. Under low temperatures, the capacity of the battery decreases.
Remark: If the control is not to be operated for a longer period of time, then the battery pack should
be disconnected. To this aim remove the cable from the + terminal of the battery.
Caution: the removed terminal should not touch any other conductive parts!
Attention:
Protect the battery pack against deep discharge!
Short circuit of the battery shall be prevented at all times!

11.4 Level sensor and float switch connection

When the control is operated with an internal level sensor, then it has to be connected to the
connections of level 1. A possible high water float switch has to always be connected to the SWHW
input. When the control is operated with float switches
applies:
Measuring method
Level sensor
Impact pressure
1 x float switch
2 x float switch
3 x float switch
(only HSK25)

Due to the low currents, it is recommended to use float switches that feature gold flashed contacts.
