®

 functions

All alarm functions such as Alarm 1 and Alarm 2 (prewarning and main 
alarm), the operating principle of the alarm relays K1 and K2 (N.O = N/O 
operation, N.C = N/C operation), the fault storage behaviour and a selection 
of two current output ranges are set in this menu.

5.4.1  Response values Alarm 1 and Alarm 2

The response values Alarm 1 and Alarm 2 are selected with the UP/DOWN 
keys and stored with the ENTER key.

5.4.2  Operating principle of the alarm relays

K1/K2 are factory set to N.O Test, that means N/O operation. When the sup-
plement "Test" has been selected, the alarm relays switch over during a man-
ual self test. 
If, for any reason, the alarm relays may not switch over during a manual self 
test, the settings N.C or N.O are to be selected.

K1:  N.C Test = N/C operation contacts 11-12-14, with relay test

(the alarm relay is energized during normal operation)

K1:  N.O Test = N/O operation contacts 11-12-14, with relay test

(the alarm relay is deenergized during normal operation)

K1:  N.C

= N/C operation contacts 11-12-14, without relay test

(the alarm relay is energized during normal operation)

K1:  N.O 

= N/O operation contacts 11-12-14, without relay test

(the alarm relay is deenergized during normal operation)

K1:  Flash 

= Flashing function contacts 11-12-14

(the alarm relay and the LED flash in the event of an alarm

                        message, approximately 0.5 Hz 
K2:  N.C Test = N/C operation contacts 21-22-24, with relay test

(the alarm relay is energized during normal operation)

K2:  N.O Test = N/O operation contacts 21-22-24, with relay test

(the alarm relay is deenergized during normal operation)

K2 : N.C 

= N/C operation contacts 21-22-24, without relay test

(the alarm relay is energized during normal operation)

K2 : N.O 

= N/O operation contacts 21-22-24, without relay test

(the alarm relay is deenergized during normal operation)

K2 : Flash 

= Flashing function contacts 21-22-24

(the alarm relay and the LED flash in the event of an alarm
message, approximately 0.5 Hz)
