10.2.5 Activating the password protection
If password protection is activated, the dosing pump is protected against
unauthorized access. You can only perform settings after entry of the
correct password.
WARNING
Caustic burns or other burns through dosing media!
If the password protection is activated, operation of the dosing pump
is blocked. The only way to stop a dosing pump without entry of the
password is via the power supply. In unfavourable cases, if the
password protection has been inadvertently activated or the user has
forgotten the password, the dosing pump cannot be stopped in time.
This can result in injury.
ð
Install an emergency stop switch or integrate the dosing pump into
the plant safety concept.
You can set any password you like from 0001 to 9999.
