Locks - ABB TZIDC Manual

TZIDC, TZIDC-200 DIGITAL POSITIONER | COI/TZIDC/TZIDC-200-EN REV. B 9

Locks

Positioner operation can be inhibited completely or partially via
the digital input and the FUNCTION parameter in parameter
group 10 (DIG_IN (digital input)).
This allows the user to prevent or restrict operating actions of
unauthorized personnel as desired. When operation is disabled
in this way, the key symbol is indicated in the display.
The following levels of configuration locks are possible:
Inhibiting the local configuration
Local operation on the operating level and remote operation and
configuration via a PC are still possible.
Inhibiting all local operating functions
No local operating actions can be executed. Both the operating
level and the configuration level are locked. Remote operation
and setting of parameters via a PC is still possible.
Inhibiting local operation and remote configuration
It is not possible to operate or configure the positioner locally or
configure it using a PC.
Note
This lock can only be deactivated if a voltage of 12 bis 24 V is
present on the digital input of the positioner (see parameter
function selection in parameter group 10 page 36).
