IDEC SmartRelay installation and wiring
IDEC SmartRelay Manual 50
2.4.2 Operating states
IDEC SmartRelay Base operating states
IDEC SmartRelay Base/Pure knows two operating states: 
STOP and RUN
Note
After switching the mains on, the system briefly switches through 
the outputs on the FL1D-H12SND. With an open circuit, a voltage 
of > 8 V can occur for up to approximately 100 ms; when loaded, 
this time reduces to a matter of microseconds.
STOP RUN
• The display shows: 
'No Program'   
(not FL1D-B12...)
• Switching IDEC SmartRelay 
to programming mode 
(not FL1D-B12...)
•LED is red 
(only FL1D-B12...)
• Display: Screen mask for 
monitoring I/Os and messag-
es (after START in the main 
menu) 
(not FL1D-B12...)
• Switching IDEC SmartRelay 
to parameter assignment 
mode 
(not FL1D-B12...)
• LED is green 
(only FL1D-B12...)
Action of IDEC SmartRelay:
• The inputs data is not read.
• The circuit program is not ex-
ecuted
• The relay contacts are per-
manently open or the transis-
tor outputs are switched off
Action of IDEC SmartRelay:
• IDEC SmartRelay reads the 
status of the inputs
• IDEC SmartRelay uses the 
circuit program to calculate 
the status of the outputs
• IDEC SmartRelay switches 
the relay/transistor outputs 
on or off
