Parameter group 10: digital input
3.14.1
FUNCTION – Digital input function selection
For the digital input, one of the following protective functions
can be selected via local operation.
— No function (default)
— Move to 0 % position
— Move to 100 % position
— Hold previous position
— Disable local con
fi
guration.
— Disable local con
fi
g uration and operation
— Disable all access (local or via PC)
The selected function is activat ed when the 24 V signal is no
longer connected to the digital output (< 10 V DC).
The safety functions
POS_0 %
,
POS_100 %
and
POS_HOLD
are executed on the operating le vel in both control operating
modes
P1.0
or
P1.1
.
BIN_CTRL
is shown in the display.
If a corresponding function is active, a corresponding value is
de
fi
ned internally for the positioner. The actuator is then driven
into the end position or position speci
fi
ed under consideration
of the set point ramp, con
fi
gured operating range, selected
behavior etc.
After selecting an operation lock
CNF_LOCK
,
OP_LOCK
or
ALL_LOCK
, the key icon is displayed, indicating that the
operation lock will be activ ated at the next save.
After saving and without 24V at the digital input, the key is
permanently displayed.
NOTE
The operation lock
CNF_LOCK
,
OP_LOCK
or
ALL_LOCK
is
displayed only if the voltage is connected to the digital input.
CNF_LOCK
Local access to the con
fi
guration level is inhibited.
However, local operation on the operating level is
possible. The positioner can be con
fi
gured externally
(via LCI / modem and PC).
When the operator tries to activate the con
fi
guration
level, the text
CNF_LOCK
is displayed for approx. 5
seconds.
OP_LOCK
Local operation and con
fi
guration is completely
inhibited. With every attempt to perform local operating
actions, the message
OP_LOCK
is shown for approx. 5
seconds.
NOTE
The positioner can be con
fi
gured externally (via LCI / modem
and PC).
ALL_LOCK
Local operation (operating level and con
fi
guration level)
and external con
fi
guration via LCI / modem and PC are
inhibited. With every attempt to perform local operating
actions, the message
ALL_LOCK
is shown for approx.
5 seconds.
3.14.2
EXIT – Return to operating level
With this parameter you can leave the con
fi
guration level. The
positioner returns to the operating level. Here you can either
save data in the non-volatile me mory or discard all previously
made changes (also the changes in other parameter groups).
To leave the con
fi
guration level (with or without saving), press
and hold
ENTER
until the countdown from 3 to 0 is
fi
nished.
The active saving process is indicated by the message
NV_SAVE
. After saving a plausibility check is executed.
If an error occurs during the check or while saving, the data
cannot be saved and an error message is displayed instead
(see Chapter "Error codes" on page 33).
Selection
NV_SAVE
Saves settings in the non-volatile memory.
CANCEL
Discards all changes made since the last
permanent save operation.
