6.5 Hardware lock
After Fieldgate has been commissioned, a local hardware lock can be set that prevents any
modifications to Fieldgate settings via Internet, GSM or Modem.
6.5.1 Activating the hardware lock
NOTE!
• You require local access to the Fieldgate to deactivate the lock!
Procedure 1 If not already selected, press "Switch to Administrator Mode" and log in as administrator.
2 Press Settings => Special, then scroll down to Miscellaneous Settings :
3 Check the box Enable Configuration Hardware Lock , then press Send
– The hardware lock is now enabled
6.5.2 Deactivating the hardware lock
NOTE!
• The service interface is not affected by the hardware lock and can always be used to access the
Fieldgate!
• The lock cannot be deactivated when the Fieldgate is booting - this causes a device reset.
The lock can be deactivated temporarily by pressing the reset button for 1 second, see chap. 9.2.
This allows access for five minutes, after which the lock is enabled again. Pressing the reset button
for 5 seconds enables the lock immediately.
The lock can be deactivated permanently by first temporarily unlocking it, then disabling it by
unchecking the
Enable Configuration Hardware Lock box and pressing Send . Alternatively this
can be done via the Service Interface.
