Setting The Transformer Load (An1, Sst, T ) - AEG Thyro-A Operating Instructions Manual

Setting aid for ...H RL1 and ...H RLP1
There is a setting aid for the potentiometers.
• Connect the measuring device to the analog output (X2.9 (+) to X2.5
ground).
> If a potentiometer is altered, the set value of the potentiometer is
output at the analog output and not the actual value.
> If the device is operated on mains voltage, the red LEDs flicker for
the duration.
> If the potentiometer is not greatly altered for 30 secs., the device
automatically switches back to output of the selected actual value.
Since the analog output is designed for 0 - 20mA / 10V, 10mA (or 5V)
correspond to 100%. This means that the set values can be read off
directly or in percentages of the nominal value.

Setting aid for ...H1, ...H RL1 and ...H RLP1
There are two setting options:
• Count the no. of turns of the potentiometer. The potentiometers have
a setting range of 18 turns. (The setting range is not guaranteed and
may deviate. If accurate settings are required, the potentiometer
must be checked using a different method.)
• Visualize the setting with PC and THYRO-TOOL FAMILY.
4.3.1 Setting the transformer load (AN1, SST, T
The settings described are relevant in operating mode TAKT.
• Set transformer load and SST on potentiometer R201 TRAFO AD-
APTION (Default setting: 60° el. with Thyro-A 1A as well as 90° el.
with Thyro-A 2A and -A3A).
If wound core and toroidal core transformers are used, an optimiza-
tion of this setting can be required.
With Thyro-A 1A generally 80°el turn (to the right), with Thyro-A 2A
and Thyro-A 3A turn at smaller angles (to the left). An optimal setting
is achieved when the rush current is minimal.
