D-500 User Manual Rev_06 Firmware V-5.8
K35D05-EN - 112 -
SNTP (simple network time protocol) communication allows the controller to querry high precision, atomic
clock based date/time servers through the internet and to adjust its internal real time clock to these
servers.
Thanks to the SNTP communication, the internal RTC will reach an atomic clock precision.

Description
SNTP Refresh Period
30 sec
This is the wait period between two SNTP requests of
the unit in order to update its internal real time time
clock from the servers.
SNTP Address 1 Port
123
This is the port number of the first SNTP server.
SNTP Address 2 Port
123
This is the port number of the second SNTP server.
SNTP Address 1
0.tr.pool.ntp.org
This is the IP address of the first SNTP server.
SNTP Address 2
1.tr.pool.ntp.org
This is the IP address of the second SNTP server.

If the phase and voltage
synchronization is not successful before
the expiration of this timer, then a
Synchronization Fail
warning is given
and the transfer will be performed with
interruption.

When synchronization is detected, both
contactors will stay closed during this
timer.
Max Freq Difference

0.1
2.0
0.5
This is the maximum difference
between mains and genset frequencies
to close both contactors.

This is the maximum difference
between the mains phase-L1 and the
genset phase-L1 voltages to close both
contactors. If voltage transformer is
used, this quantity is multiplied with
voltage transformer ratio.
Max Phase Difference
deg.
0
20
10
This is the maximum phase angle
between the mains phase-L1 and the
genset phase-L1 voltages to close both
contactors.
Phase Offset
deg.
-60
+60
0
This parameter is used to compensate
the phase angle introduced by voltage
transformers in case of MV
synchronization. This angle value is
added to the phase differential during
phase matching process.
