be set. If during operation a value transgresses one of these limits, the device gener-
ates an alarm which is displayed as an operational indication. As for all operational in-
dications, it is possible to output the information to LED and/or output relay and via in-
terfaces. In contrast to the actual protective functions, such as time-overcurrent
protection or overload protection, this monitoring program runs in the background and
may not respond promptly during a fault if the measured values change rapidly and
protective functions pick up. Moreover, since an indication is not generated until the
set limit value has been transgressed several times, these monitoring functions cannot
respond immediately before a protection trip.
With the 7UM61, only the limit value of the undercurrent protection IL< is configured
when the device is delivered from the factory. Further limit values can be configured if
