Inputs
If you use the optional 3DI/LC module (3RK1908-1AA00-0BP0), the motor starter can
execute various actions with the "Inputs" device function. The actions are parameterizable.
The signals are evaluated on the 3DI/LC module for this purpose. Inputs 1 to 3 (DI 0.4 to 0.6)
can be connected directly with contact elements or sensors.
The bit 2.5 in the process image of the inputs indicates whether a 3DI/LC module is inserted.
The signal states are transferred in parallel via the process image. In addition, the signal
states in DS92 Read device diagnostics (Page 186) can be read out. The input actions of the
individual digital inputs affect the motor starter functions independently of one another.
The input LC (local control) switches over to manual local mode. You cannot change the
parameterization of the input. This input is always implemented as a NO contact. You can
detect whether or not manual local is active if bits 0.7 and 1.6 are active in the process
image input.
For information on this topic, see Chapter "Connecting the 3DI/LC module for the
motor starter" in the ET 200SP System Manual

Inputs for commissioning
To ensure operation of a motor in the unparameterized state of the ET 200SP motor starter
with the aid of the 3DI/LC module, the input parameters in data set 201 are permanently
assigned the following values by default:
●
DI1: Motor CW
●
DI2: Motor CCW
●
DI3: Cold start (fail-safe motor starters as of V1.2.0)
This pre-parameterization is overwritten when the ET 200SP motor starter is parameterized.
Response to sensor supply overload
The supply voltage for the digital inputs is short-circuit proof. The current is limited to a
maximum of 100 mA. If a short-circuit or overload situation occurs in the sensor supply, the
switching elements (motor) are shut down and a group fault is output. Acknowledge the fault
with Trip Reset.
