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 - 20 mA / 10 V, 10 mA (or 5 V)

correspond to 100%. This means that the set values can be read off

directly or in percentages of the nominal value.

Analog output setting aid

20.0 mA bzw.10 V 200%

10.0 mA bzw. 5 V 100% bzw. 100°el.

5.0 mA bzw. 2.5 V 50% bzw. 50°el

2.5 mA bzw. 1.25 V 25% usw.

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

ADAPTION (Default setting: 60° el. with Thyro-A 1A as well as 90° el.

with Thyro-A 2A and -A3A).

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.

In order to minimise the rush current for transformers, it is possible to

alter the angle of the ﬁrst half wave on potentiometer R201 TRAFO

ADAPTION.

Only for ...H1

Before adapting the transformer load:

• Switch DIP switch S1.5 to OFF

4.3.2 SETTING OHMIC LOAD

• Recommendation: Set potentiometer R201 TRAFO ADAPTION to

left stop.

> T

= 100ms

> Faster TAKT period is set.

> No phase angle of ﬁrst half wave is set.

> Soft start time (SST) set to „0“.

Soft start time SST

The SST is set at the same time. This also applies to operating mode

VAR. The soft start time has the following values depending on AN1:

AN1[°el] SST [per] SST [ms/50Hz] TURNS

<60 0 0 9

<63.7 6 120 10

>63.7 7 140 10

>71.2 8 160 11

>78.8 9 180 12

>86.2 10 200 13

>91.5 11 220 13

>94.5 13 260 14

>97.4 15 300 14

>100.5 20 400 15

>103.5 30 600* 15

* For a soft start time SST of 30 periods or 600ms, the power controller

remains in the SST ramp until setting time (T

) is greater than 600ms.

The power controller then pulses without SST ramp, even if T

is less

than 600ms. As soon as the power controller reaches the setpoint, the

SST becomes smaller and the ramp is always crossed once fully.
