Latched or un-latched alarm
Fig. 3
Wiring example for latched or un-latched alarm.
When using DC voltage, alternatively see Fig. 11, page 29.
If terminal 5 is not connected, see Fig. 3, the alarm is not automatically reset
when the machine load is normal again after an alarm situation. The alarm is
then latched; function "Latched alarm". The alarm can then be manually reset
by pressing both PAR and VAL buttons at the same time for 3 seconds. It is only
possible to reset an alarm if the power level is on the "right side" of the set alarm
level (depending on under- or overload monitoring).
If, however, terminal 5 is connected to an AC or DC signal the alarm will be
reset automatically (un-latched alarm). This is only possible if the power level is
on the "right side" of the set alarm level.
Un-Latched (Auto Reset)

terminal 5 and 6.
