8.1 Power output control
Power output control
Zero-point switching solid state relays are used for controlling the heating elements. Nine
individually-controllable power outputs are implemented.
They are controlled in half-waves: For each half-wave, the controller supplies On/Off
information to the relay and this switches as specified at the next zero point.
The setpoints for controlling the power outputs lie within a value range of 0 % to 99 %
(reference value: 100 half-waves).
Depending on the specified setpoint, the power outputs are controlled with an equal number
of positive and negative half-waves (reference value: 200 half-waves).
To avoid excessively high inrush currents, the power outputs are switched on time-delayed.
