The memory module is used to store your CL circuit diagram,
together with its parameter and CL settings. The data on the
memory module will be retained without an external power
supply.
The memory module is fitted in the interface provided for it.
See Retention.
The logic relay has eight operating buttons. These are used
to select menu functions and create circuit diagrams. The
large round button in the middle is used to move the cursor.
DEL, ALT, ESC and OK all perform additional functions.
The logic relay has two operating modes: RUN and STOP.
RUN mode is used to process your CL circuit diagram (with
the controller running continuously). In STOP mode you can
create your circuit diagrams.
You can connect various loads to the logic relay outputs,
such as contactors, lamps or and motors. In the circuit
diagram the outputs are controlled via the corresponding
output relay coils Q1 to Q8 or S1 to S8.
Parameters enable the user to set the behaviour of function
relays. The relevant parameters apply for switch times or
counter setpoints. They are set in the parameter display.
The P buttons can be used to simulate four additional inputs
which are controlled directly by the four cursor buttons,
rather than via external contacts. The switching contacts of
P buttons are connected up in the circuit diagram.
