5.5.5.2 Password for fail-safe functions
Description
There are four parameters associated with the password protection system. All these
parameters require level 3 access (only important when using OP) – the parameters are as
follows:
r9760 – shows the currently valid password for fail-safe function parameters.
P9761 – used to enter the password.
P9762 – used for entering a new password (5 digits with no leading zero (0)).
P9763 – used to confirm a new password.
When a password is entered (5 digits with no leading zero), it is compared with the password
held in r9760.
If correct, access is granted.
If incorrect, the parameters for fail-safe functions will be locked out and the user will have to
manually exit the commissioning mode for fail-safe functions by using parameter P3900 = 11
which cancels all previous changes to the parameters for fail-safe functions.
To change the password see "General steps for commissioning of fail-safe functions"
