Line Control

Line control is a short-circuit and line-break monitoring system, for example, E-stop inputs that

are configured for the 1753-IB16 system.

For line control, the device has four digital pulse test sources (PO) connected to the following

terminals.

The example below shows two pulse test sources connected to the digital inputs (DI) of the same

system. As a result, the connections to the digital inputs (DI) are monitored.

Inputs are set to 0, a fault code is generated, and the FAULT status indicator is on when:

• a short-circuit occurs between two parallel connections.

• two connections are reversed.

• earth fault occurs on one of the lines (only with earthed reference pole).

• a line breaks or one of the contacts opens (that is, when one of the E-stop off switches is

pressed in the example above).
