Security
Deactivating Passwords during Commissioning
It is possible optionally to deactivate passwords during commissioning. It is not allowed to use this feature for other
purposes than commissioning. In order to deactivate the password protection replace the existing password with an
empty one for the corresponding access areas. All access authorizations (access areas) that are protected by an
empty password are unlocked permanently. That means, that all parameters and settings within those areas can
be modified without any further access authorization. It is no longer possible to change into the »
Read Only-Lv0«
level (the protective device will also not fall back into this mode if the maximum edit time is expired (t-max-Edit).
You have to ensure that all passwords are activated again after the
commissioning. That means, that all access areas have to be protected by a
password that consists of 4 digits as minimum.
Woodward will not take over any liability for any personal injuries or damages
that are caused by deactivated password protection.
Password Forgotten
It is possible to reset all passwords via a general Reset dialog. See “Reset to Factory Defaults, Reset All
Passwords” for details.
General Considerations
You have to ensure that the access authorizations are protected by secure passwords. These passwords have to
be kept as a secret and to be known only by the authorized persons. The default password “1234” does not provide
any security against unauthorized access.
A lock symbol indicates in the upper right corner of the display if there are any access authorizations active at the
moment . That means, within the mode "Read Only Lv0" a closed (locked) lock symbol will be shown in the upper
right corner of the display. As soon as there are any access authorizations active (above the "Read Only-Lv0"
level), the upper right corner of the display will show an unlocked (open) lock symbol.
During setting parameters the C-Button can be used for canceling the parameter changes. Because of that it is not
possible to acknowledge (LEDs, Output Relays...) as long as there are non-saved (cached only) parameters.
The acknowledgment menu cannot be accessed as long as the parameter modifications are not overtaken by the
device (indicated by a star symbol in the upper left corner).
The passwords are part of the device (fixed assignments). That means, passwords will not be overwritten, if a
parameter file is transmitted into a device.
Existing passwords are persistent (assigned to a device). If an offline created parameter file is transmitted into a
device, or if a parameter file is transmitted from one device to another, this will have no impact on existing
passwords within the device.
