Description

A smart relay allows you to enter 120 line Ladder diagrams.

The smart relay’s display screen is used to display these lines, 4 at a time, in the

following manner:

Z1-----------

Prompt Element

1 Column reserved for contacts (conditions).

2 Column reserved for contacts (conditions) and for links.

3 Column reserved for coils (actions).

4 Column reserved for links.

Each line comprises 5 fields each with 2 characters reserved for contacts (conditions). The 4 central columns can also accept links. The last three-character column is reserved for coils (actions).

Links must be entered between the contact and coil columns.

A ladder diagram is entered into the smart relay using the front panel keys (see Control Keys on the Front Panel of the Smart Relay, p. 20).
