This section contains the instructions necessary to
configure the 1200/1300 Controller according to the
needs of the application..
Optimal working operation of the 1200/1300 Controller in the
field of application it is intended for depends largely on correct
configuration and programming of the relevant control
parameters.
The flexibility and high performance level of these instruments
is in fact based on the numerous parameters that can be
programmed directly by the user with the buttons on the con-
trol panel, or transferred from a PC, in the form of configu-
ration files, by means of the RS485 interface available as an
option on 1200/1300 Controllers.
Easy configuration
To simplify the Controller configuration and programming pro-
cess in the most common temperature control applications,
that do not require very complex controls, there is a simplified
level of configuration ("Easy") suitable for the basic instrument
versions, with just two outputs (Out1 - Out2).
The Easy configuration essentially has three menus:
:
general Controller configuration
(FG
:
input functioning mode
INP
:
output functioning mode
0VT
which involve setting a limited number of parameters
(maximum 13), as well as setting the AL.1 alarm point that
can be done directly in level 1.
Extended Configuration
Access to all the configuration / programming menus and to all
the parameters available for the 1200/1300 controllers in
extended configuration, allows every detail of the Controller to
be configured, to satisfy all application requirements.
Correct setting of the parameters involved in the
extended configuration presumes a high level of
knowledge regarding temperature control problems
and techniques, and so it is recommended that these
parameters are not changed unless the user is fully
aware of the consequences, that could arise form
incorrect settings.
It is the user's responsibility to check that the
parameters are set correctly before putting the
Controller into service, in order to avoid damage to
persons or property.
For any doubts or clarification needed, please visit the
Web Site www.gefran.com and if necessary contact
the Gefran Customer Care service..
To select the Extended configuration mode, 128 must be
added to the value of the PRO parameter that appears when
scrolling through the Controller menu - see Navigating through
the Controller Menus.
The following pages describe one by one the various
Controller menus and show for each parameter the concise
description of the function performed, any default values and
the range of values that can be set.

Supplementary notes on consulting the Configuration/
Programming pages
To set some particularly complex parameters certain tables or
detailed explanatory notes must be referred to.
These tables or explanatory notes are shown directly on the
right of the page next to the parameter in question.
Application notes
The detailed explanations of certain functioning modes
or special techniques the result Gefran's lengthy
experience in the field of temperature control are inste-
ad
contained at the end of the Configuration/Programming
Section and can represent a valuable reference tool for
the user.
Where necessary, in the configuration / programming
flows the appropriate referrals to these Application
Notes are provided.
Password: PAS
When scrolling through the menu (keeping
down), following the 0VT menu, the word PAS appears.
Access to the next menus is only possible if the PAS = 99
parameter is set to 99 by pressing
Having set the value to 99, press
down to access the next menus.
Protection code: PRO
The PRO parameter is used to choose between the "Easy" and
the "Extended" configuration, and is also used to enable or
disable the display and/or the possibility of editing certain
parameters. For further details refer to the description of the
PRO parameter in the configuration flows..
Jumper S4 on CPU Board
The absence of jumper S4 on the CPU board of the Controller
prevents access to all the menus when the hardware
configuration of the instrument does not require the pre-set
parameters to be changed.
This jumper is engaged or disengaged during production and
normally does not need to be modified by the final user.
For further information, refer to Section 6 - Maintenance.
