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.
