Connecting The Bus Module - AEG Thyro-A Operating Instructions Manual

• Configure operating mode TAKT (see page 41, Operating mode and
load type).
• Turn potentiometer R201 TRAFO ADAPTION to left stop (see page
44, potentiometer).
• Connect signal generator (e.g. 2-point controller) to terminal X2.7.
> The device switches on at a signal level of > 3 V

5.7 Connecting the bus module

The way in which the bus module is connected to the power controller
decides the type of setpoint processing (see page 19, Setpoint pro-
cessing). Terminal X22.1 controls the processes (we recommend the
use of preassembled connection cable 2 000 000 848 / 849).
Setpoint of the anlogue control terminal only
• Do not make any connections to terminal X22.1.
> Only the analog signal (X2.4 (+); X2.3 (ground)) is used as
setpoint.
Setpoint of bus module only
• Connect ground to terminal X22.1.
> Only the value of the bus module is used as setpoint.
Defined setpoint for bus failure
There are two possibilities:
• Connect terminal X22.1 on the master of the power controller to
terminals X1.1 ... X8.1 of the bus module.
> Cable to X22.1 is switched in the event of a malfunction.
> In the event of malfunctions along the bus line, the system automa-
tically switches to the analog setpoint at the control terminals of the
power controller.
• Connect terminal X22.1 on the master of the power controller to
terminals X1.5 ... X8.5 of the bus module.
> Cable to X22.1 is switched in the event of a malfunction.
> Depending on the settings on the bus module:
In the event of malfunctions along the bus line, the system automa-
tically switches to the analog setpoint at the control terminals of the
power controller or the last setpoint is maintained. In addition to this,
each device connected to the bus module can be enabled individually
via the bus on „Hand" (see bus module instructions).
