Work optimization of power limit function (alarm switch on delay):
delay time of the alarm
t
o
= 10% * [1 MW * 900 s/ 1.5 MW] = 60 s
(register
4019
).
Figure 20 presents how to take advantage of the parameter showing
used ordered power to activate alarm. The alarm delay is switched off
(set to 0 sec.) - register 4019.
In the example for the remaining 10% of ordered power under maxi-
mal power consumption the devices could work yet 60 seconds without
exposing the consumer to penalties. If the delay was set to 60 seconds
the alarm would not be activated (register 4019).

time, synchronization with the clock, alarm set to 90%.
