Failure Indication
The Competition control box is provided with an automatic failure recognition. The failure type is
shown.
In case of failure, the total LED-scale flashes red and the display shows the type of failure.
Moreover, it is possible to signal a failure via a potential-free contact. The correct connection is
shown in the terminal plan and such relay-contact can be load as below:-
Rated current:
6A
Rated voltage:
250V AC
max. breaking capacity:
1500W (class AC1
– Ohm load)
max. breaking capacity:
300W (class AC15
– electro-magnetic load)
min. breaking capacity:
500mW / 12V / 10mA
Failure 1:
Undercurrent
Coil not closed, faulty connection control box
→
water unit
Failure 2:
Overload
Short cut of coil, faulty coil
Failure 3:
Short cut
Short cut in coil connection (visible during initialisation)
Failure 4:
Control box failure
failure in any electrical component of the control box, e.g. faulty components
