3. Functions
3.1 Processing the setpoint Thyro-S
Only local setpoints, no bus setpoint
Switching signal (24DC) at the control terminal X22.1 of the Thyro-S
> No wiring of the terminal point X22.4 at the power controller
- The bus module is fully functional. The analog signal from the control terminal X22.1 is used as setpoint
(on/off).
Setpoint from the bus module (X22.3), no local setpoint
> Connect the ground to terminal X22.4 of the power controller.
- The master setpoint of the bus module is used. For this purpose the setpoint is interpreted as the ope-
rating mode.
Bus setpoint, switching over to „local“ in case of bus fault
Only use the setpoint of the bus module if there is an IO connection.
> Connect terminal X22.4 of the power controller to one of the terminals X1.1 to X8.1 of the bus module.
- If there is an IO connection the master set point is used.
If not then the analog signal from the control terminal X22.1 is used as setpoint (on/off).
Switching over to bus / local setpoint switchable for each controller in operation
Individual setpoint from the bus module for each power controller.
> Connect terminal X22.4 of the power controller to one of the terminals X1.5 to X 8.5 of the bus
module.
- The power controllers can be switched over individually (targeted) via the bus between master setpoint
and terminal X22.1
3.2 Processing the setpoint Thyro-A
Only local setpoints, no bus setpoint
Analog input at control terminal X2.4 of Thyro-A
> Do not connect anything to terminal X22.1 of the power controller.
- The bus module is fully functional. The analog signal from the control terminal X2.4 is used as setpoint
(on/off).
Setpoint from the bus module (X22.3), no local setpoint
> Connect the ground to terminal X22.1 of the power controller.
- The master setpoint of the bus module is used.
Bus setpoint, switching over to “local” in case of bus fault
Only use the setpoint of the bus module if there is an IO connection.
> Connect terminal X22.1 of the power controller to one of the terminals X1.1 to X8.1 of the bus module.
- If there is an IO connection the master setpoint is used. If there is no IO connection then the analog
signal from the control terminal X2.4 is used as setpoint.
Switching over to bus / local setpoint switchable for each controller in operation
Individual setpoint from the bus module for each power controller.
> Connect terminal X22.1 of the power controller to one of the terminals X1.5 to X8.5 of the bus module.
- The power controllers can be switched over individually (targeted) via the bus between master setpoint
and terminal X2.4.
