9. Examples of Transducer Programming
Example 1 – Programming an Alarm 1 with Hysteresis
Program the operation of the alarm 1 in such a way, that at the value
250 V of the phase 1 voltage, the alarm will be switched on, however
switched off at the value 210 V.
For
the rated U
n
= 230 V execution,
one
must s et up values
from t he
table 7.
Regi-
ster
Value
Meaning
4015
1
1 – voltage of phase 1 (U1)
4016
0
0 – n-on mode
4017
913
913 – 91.3% (percentage value with one place after the
decimal point multiplied by 10) of the rated voltage of
phase 1 – alarm switched off,
(210 V/230 V) x 1000 = 913
4018
1087
1087 – 108.7 % (percentage value with one place after
the decimal point multiplied by 10) of the rated voltage of
phase 1 – alarm switched on,
(250 V/230 V) x 1000 = 1087
4019
0
0 – 0 second delay in the alarm switching
4020
0
0 – 0 second delay in the alarm switching off
4021
0
0 – 0 second deadlock for the alarm re-switching

Example 2 – Conguring alarm of ordered power exceeding
Set the alarm of the earlier warning of ordered power exceeding po-
ssibility on 90% level by 15-minutes (900 sec.) calculation. Current
transformer 2500 : 5 A, voltage U
n
=230 V. Temporary maximal power
consumption 1.5 MW.
Calculate:
3-phase rated active power of the transducer : P = 3 x 230 V x 2500
A (500 * 5A) = 1.725 MW (500 * 3450 W) i.e. 100%
Ordered power and rated power ratio = 1 MW / 1.725
57.97%
of the
tarnsducers rated value (register
4010
).
Hysteresis of alarm work: alarm switching
for
90%
of ordered power (re-
gister
4018
), switching off for example: by 1% lower - 89% (register
4017
)
