Kessel Mono Manual page 29

Float switch, Mono/Duo
Check whether the system is a Mono or a Duo system.
Define level for ON 1, if applicable, ON 2 (Duo) and OFF.
KESSEL recommends providing an alarm level for the
items named above.
If a float switch fails, the float switches can be swapped
temporarily so that the OFF level does not have to be
used. The switching off is then set in the control unit via
the post run time of the pumps. See
run time |
under the Settings menu and Parame-
ter selection. This procedure is not suitable for contin-
uous operation, as dry running of the pumps should be
avoided.

Potential-free contact (optional accessory)
If required, signal generators or other accessories can be connected as potential-free contacts (42 V 0.5 A). The following
terminals are available for these:
Warning (event is displayed - e.g. alarm level exceeded) -normally closed-
Fault (fatal error - e.g. in electrical connection or safety systems) -normally open-
In the event of a warning, the operating reliability of the system is usually not immediately at risk; however, the system
should be subjected to maintenance or checking by a competent person without delay. In the event of a fault, the function of
the system can be directly impaired, there is a need for direct action. Contact the service technician or emergency service.
