gefran 2500 User Manual

4 • CONFIGURATION / PROGRAMMING
This section contains the instructions needed to confi-
gure the 2500 Controller as required.
To provide optimum functioning in its intended application, the
2500 Controller’s control parameters have to be correctly con-
figured and programmed. The flexibility and high performance
of these instruments is based on numerous parameters that
the user can program directly via the control panel buttons, or
transfer from PC in the form of configuration file via the optio-
nal digital communication interface.
Configuration
Access to all configuration / programming menus and to all
parameters available for the 2500 Controllers means that the
Controller can be configured extremely precisely to satisfy any
applicative requirement.
The correct setting of configuration parameters
assumes expertise in control problems and techni-
ques. Therefore, do not change these parameters if
you are not fully aware of the consequences that may
derive from improper setting.
To prevent harm to persons or property, the user
is responsible for checking that all parameters are
correctly set before the Controller is put into ope-
ration.
If you have any doubts or need any explanation,
consult the website www.gefran.com or call Gefran
Customer Care.
The following pages describe each of the Controller’s menus
and, for each parameter, provide a concise description of its
function, its default value (if any), and its range of settable
values.
Example: Parameter IT.1 on (FG menu
(default value)
Integral time of Pid 1 group
[0.0 ... 99.99] min
Supplemental Notes for Consultation of Configuration/
Programming Pages
When setting a few highly complex parameters, you need to
consult certain tables or detailed notes.
These tables or notes are found on the right side of the page
for the parameter in question.
Applicative Notes
Detailed explanations of certain operating modes or
special techniques developed by Gefran in its years of
experience in the control field are provided at the end of
the Configuration/Programming Section, and are a
valuable consulting tool for the user.
References are made to these Applicative Notes, where
necessary, in the configuration / programming flows.
Password: PAS
The message PAS appears when scrolling the menus (button
kept pusched), after the 0VT menu.
Subsequent menus can be accessed only by setting the para-
meter PAS = 99, then pushing .
After setting the value 99, push and keep pushed to
access subsequent menus.
Protection Code: PRO
The PRO parameter lets you enable or disable the display and/
or change of certain parameters.
For details, see the description of the PRO parameter in the
configuration flows.
Jumper S9 on CPU Board
The absence of jumper S9 on the Controller’s CPU board
blocks access to all menus when the instrument’s hardware
configuration does not required any change of preset parame-
ters.
This jumper is inserted or removed in the factory, and normally
does not need to be changed by the final user.
For more information, see section 6 - Maintenance.
