All of these negative effects can be avoided or reduced to a minimum
level by using the Thyro-Power Manager.
The Thyro-Power Manager has a total of 10 digital outputs at the
terminals (figure 12, page 78) X3 and X4. These are set up as poten-
tial-free optical coupler outputs. When optimising the network load
they are used as synchronization outputs (SYT) for the connected
power controllers or power controller groups. All cables are to be laid
shielded with the shield grounded at the output switch. (Please find
details in the Thyro-Power Manager operating instructions available
separately)
Characteristics:
• Minimal mains peak load and realted mains feedback rates.
• Changes to the setpoint and load do not automatically feed into the
mains load optimization.
• Can also be used in connection with already existing AEG power
controllers.
6.3 Software synchronization (operating mode TAKT)
Software synchronization is a method of mains load optimiza-
tion where an optional bus module is used or the THYRO-TOOL
FAMILY. The software synchronization is set by entering a parameter
(Parameter 36).
• Set the cycle period T
0
to the same value for all power controllers
(recommended: T
0
=1 sec.).
When setting with the bus module:
• Enter value via INDEX 38.
When setting with THYRO-TOOL FAMILY:
• Enter SYNC value „Synchro cycle address“. Select a different value
for each power controller.
> A delay period up to the first switching on is set. The value is
multiplied by 10 ms.
> The length of time up to the first switching on is different for each
power controller.
This procedure allows the load to be connected slowly, e.g. with a
slow cycle time of 1 sec. Values at intervals of 100 lead to a switch on
delayed by a cycle period T
0
(group formation).This function allows
an auxiliary power generator to be connected, for example.
