Wiring with the logic relay

Operating principles

The cursor buttons in the circuit diagram perform three
functions. The appearance of the flashing cursor indicates
the current mode.
• Move
• Enter
• Connect
â
In Move mode you can use
around the circuit diagram in order to select a circuit
connection, contact or relay coil.
Use OK to switch to Entry mode so that you can enter or

change a value at the current cursor position. If you press
ESC in Entry mode, the logic relay will undo the most recent
changes.
l
Press ALT to switch to Connect mode for wiring contacts and
relays. Press ALT again to return to Move.
Press ESC to exit the circuit diagram and parameter display.
h
The logic relay performs many of these cursor movements
automatically. For example, the logic relay switches the
cursor to Move mode if no further entries or connections
are possible at the selected cursor position.
Opening the parameter display for function relays
with contacts or coils
If you specify the contact or coil of a function relay in Entry
mode, the logic relay automatically switches from the
contact number to the function relay parameter display
when you press OK.
í
Press to switch to the next contact or coil field without
entering any parameters.
Program
A program is a sequence of commands which the logic relay
executes cyclically in RUN mode. A CL program consists of
the necessary settings for the device, password, system
settings, a circuit diagram and/or function relays.
