3. Operation

3.1 Configuration switch S1

A 2-pole DIP switch is situated at the front behind the hood. The individual switches
are marked from 1-2 starting from the bottom and must be set before operation.
They are only read in once when switched on (mains recovery). For safety reasons
further operation is carried out with the hood closed.

For operations where initially no nominal load is possible (e.g.drying ) reduced
power can be controlled by Thyro-S independently.
With 1:2 operation each 2. cycle is switched, with 1:3 and 1:5 operation half
cycles are switched with alternating polarity so that while switched on the load is
supplied with d.c.-free energy.

3.2 Diagnosis / status indications

Faults can occur in the load circuit and in the controller itself or from the mains.
Diagnosis of unexpected operating behaviour is performed by LEDs on the front
panel of the control device.
