3.14 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 configuration.
— Disable local config 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
defined internally for the positioner. The actuator is then driven
into the end position or position specified under consideration
of the set point ramp, configured 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 configuration level is inhibited.
However, local operation on the operating level is
possible. The positioner can be configured externally
(via LCI / modem and PC).
When the operator tries to activate the configuration
level, the text CNF_LOCK is displayed for approx. 5
seconds.
OP_LOCK
Local operation and configuration 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 configured externally (via LCI / modem
and PC).
ALL_LOCK
Local operation (operating level and configuration level)
and external configuration 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 configuration 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 configuration level (with or without saving), press
and hold ENTER until the countdown from 3 to 0 is finished.
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.
