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 79) X3 and X4. These are set up as potential-

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 shiel-

ded with the shield grounded at the output switch. (Please ﬁnd details

in the Thyro-Power Manager operating instructions available separa-

tely)

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 Advanced

Energy power controllers.

6.3 SOFTWARE SYNCHRONIZATION (OPERATING

MODE TAKT)

Software synchronization is a method of mains load optimization 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

to the same value for all power controllers

(recommended: T

=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

speciﬁed in msec.

> 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

(group formation).This function allows

an auxiliary power generator to be connected, for example.

Example: 4 controllers, e.g. with 100A, load triggering approx. 30%
