Main Setup [200]
Section 11-2
Autoreset example:
In an application it is known that the main supply voltage sometimes disap-
pears for a very short time, a so-called “dip”. That will cause the VSD to trip an
“Undervoltage alarm”. Using the Autoreset function, this trip will be acknowl-
edged automatically.
•
Enable the Autoreset function by making the reset input continuously high.
•
Activate the Autoreset function in the menu [251], Number of trips.
•
Select in menus [252] to [25N] the Trip condition that are allowed to be
automatically reset by the Autoreset function after the set delay time has
expired.
Number of Trips [251]
Any number set above 0 activates the Autoreset. This means that after a trip,
the VSD will restart automatically according to the number of attempts
selected. No restart attempts will take place unless all conditions are normal.
If the Autoreset counter (not visible) contains more trips than the selected
number of attempts, the Autoreset cycle will be interrupted. No Autoreset will
then take place.
If there are no trips for more than 10 minutes, the Autoreset counter
decreases by one.
If the maximum number of trips has been reached, the trip message hour
counter is marked with an “A”.
If the Autoreset is full then the VSD must be reset by a normal Reset.
Example:
•
Autoreset = 5
•
Within 10 minutes 6 trips occur
•
At the 6th trip there is no Autoreset, because the Autoreset trip log con-
tains 5 trips already.
•
To reset, apply a normal reset: set the reset input high to low and high
again to maintain the Autoreset function. The Autoreset counter is reset
(not visible).
