IDEC SmartRelay installation and wiring
54 IDEC SmartRelay Manual
4. If you have enabled retentivity for at least one function, or
a function is permanently retentive, the current values are
retained at POWER-OFF.
Note
When a power failure occurs while you are entering a circuit
program, the program in IDEC SmartRelay will be deleted after
power is returned.
Before you modify the circuit program, save a backup copy of your
original to a memory cartridge, a combined memory/battery
cartridge or to a computer (WindLGC).
2.4.2 Operating states
IDEC SmartRelay base module operating states
IDEC SmartRelay base module/Pure knows has two
operating states: S
TOP and RUN.
Note
After switching the power on, the system briefly switches through
the outputs on the FL1E-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 FL1E-B12...)
• Switching IDEC SmartRelay to
programming mode
(not FL1E-B12...)
•LED is red
(only FL1E-B12...)
• Display: Screen mask for
monitoring I/Os and messages
(after START in the main menu)
(not FL1E-B12...)
• Switching IDEC SmartRelay to
parameter assignment mode
(not FL1E-B12...)
• LED is green
(only FL1E-B12...)
Action of IDEC SmartRelay:
• The input data is not read.
• The circuit program is not
executed.
• The relay contacts are
permanently open or the
transistor 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.
