Sliding setpoint PWM

The actual value x

1

 is recorded via a temperature sensor or a 

standard signal and converted into a digital signal. Before this 
signal is sent to the controller, the actual value is corrected. 
The corrected actual value is shown on the display (P01).
The actual value x

2

 is recorded via a temperature sensor or a 

standard signal and converted into a digital signal. Before this 
signal is sent to the controller, the actual value is corrected. 
The corrected actual value is shown on the display (P02).
The temperature deviation w

2

 is set on the controller and is 

used to calculate the sliding setpoint w1. 
The sliding setpoint w

1

 = x

2

 + w

2

 , is calculated in the control-

ler and shown on the display.
A hysteresis h can be set on the controller and specifies the 
range in which the controller clocks.
The control difference  x

d

 = w

1

 - x

1

 is formed in the controller.

Hybrid relay K1 (PWM)

If the control difference is  x

d

 ≤ h, the hybrid relay clocks.

If the control difference is  x

d

 > h, he hybrid relay remains 

permanently closed.
If the control difference is  x

d

 < 0, the hybrid relay remains 

open.

ontrol of an external SSR relay (PWM)

The external SSR relay is switched via a voltage signal from the 
controller.

If the control difference is  x

d

 < 0, a signal with 0/2V is sent to 

the output and the SSR relay switches off.
If the control difference is  x

d

 ≥ 0, a 10V signal is sent to the 

output and the SSR relay switches on.

Control of an external power contactor (PWM)

If the control difference is x

d

 ≤ h, the safety relay clocks.

If the control difference is  x

d

 > h, the safety relay remains 

permanently closed.
If the control difference is x

d

 < 0, the safety relay remains open.
