3.4 The four golden rules for operating IDEC
SmartRelay
Rule 1
Changing the operating mode
• You create the circuit program in programming mode.
After power is on, and when the display shows “No
Program / Press ESC”, press the ESC key to select
programming mode.
• Timer and parameter values of an existing circuit
program can be edited both in parameter assignment
mode and in programming mode. During parameter
assignment IDEC SmartRelay is in RUN mode; that is,
it continues executing the circuit program (see Chapter
5). To work in programming mode, you need to
terminate the circuit program by calling the “Stop”
command.
• Select the ’Start’ command on the main menu to set RUN
mode.
• When the system is in RUN, you can return to parameter
assignment mode by pressing the ESC key.
• When parameter assignment mode is open and you
want to return to programming mode, select the “Stop”
command from the parameter assignment menu, and
confirm “Stop Prg” prompt with “Yes”. To do so, move
the cursor to “Yes” and confirm with OK.
For more details on operating modes, refer to Appendix D.
Rule 2
Outputs and inputs
• Always create your circuit program by working from the
output to the input.
• You can connect an output to several inputs, but not the
same input to several outputs.
• Within the same program path you may not connect an
output to an upstream input. For such internal recursions
you should interconnect memory markers or outputs.
