Passwords - gefran 650 Installation And Instruction Manual

The fast configuration described in the previous chapter lets
you rapidly put the controller into operation.
To do this, the procedure configures the controller's main pa-
rameters only, which satisfies the most common application
requirements.
On the other hand, to satisfy all application requirements
and to configure the controller in detail, you have to set the
parameters that are accessible only on the Programming/
Configuration menu.
4.1. Programming/Configuration Menu
4.1.1. First: know what you're doing
Correctly setting the parameters needed to configure the
controller requires thorough knowledge of the problems and
techniques involved.
If you are unsure of your know-how, or are not fully aware
of the consequences of incorrectly setting the parameters,
we advise you not to configure the controller with this menu.
Attention! To prevent harm to persons and dama-
ge to property, the user must check that the para-
meters are correctly set before commissioning the
controller.
In case of doubts, or if you need any explanations,
please consult www.gefran.com or contact Gefran

4. CONFIGURATION
This type of configuration is also useful for common appli-
cations (the ones covered by fast configuration), because
optimum controller function depends a great deal on correct
configuration and programming of the control parameters
provided.
The controller can be configured with the buttons on its pa-
nel and from the PC with GF_eXpress software (see chapter
"7. Programming with PC" on page 159).
4.1.2.

Passwords

The configuration menu is protected by 2 passwords that
allow access to two different menu sections.
The first section, accessed with password 1, groups the
most operative submenus and parameters, i.e., the ones
most involved in daily functioning of the controlled machine
or system.
The second section, accessed with password 2, groups the
submenus and parameters used to configure HW resources
The factory password settings are:
• Password 1 = 1
• Password 2 = 2
The passwords can be changed and even disabled if you
want. See paragraphs "4.27. Submenu PASC1 - Setting
level 1 password" on page 136 and "4.28. Submenu PASC2
- Setting level 2 password" on page 136
