With the 2850T and 3850T multi-purpose controllers,
thanks to Gefran GETView technology you can create cus-
tom graphics with the touch of a finger.
Using the terminal graphic touch screen you can develop
extremely effective man-machine interfaces, both in terms
of machine and process management and in terms of visu-
alization and interpretation of their data.
Controllers allow up to 10 custom pages, of which one
(model 2850T) or two (model 3850T) can be immediately
recalled from their keyboard.
Different types of components (fields, buttons, completion
5.1. Examples of custom pages
5.1.1.

Example of Pit Kiln

The controller controls the processing temperature via a
PID (TIC), using the highest of the two T1 temperatures read
in the kiln as the reference temperature. One of the two
values read are selected with a Selection Logic Function
(MAX).
The controller also controls the pressure (P) in the kiln
through a second PID (PIC).
The page shows the process value (PV) and setpoint (SP)
values of both PIDs in numeric format, while two distinct
Bar graphs display the 2 PID control value percent. Setpoint
values can be edited from the page.
In addition, there are two components (ON/OFF buttons) for
entering the 2 process gases: ammonia (NH3 ammonia) and
nitrogen (Nitrogen H3).

Example of a Food Steriliser

The controller uses two distinct PID loops for internal

indicators, LED, text boxes, pictures, navigation keys) are
available to view and edit data within the controller.
You can also import images, such as machine diagrams or
system diagrams, to be used as a backdrop to make their
control and use even more intuitive.
To go to the customized pages, press the
(present on 2850/3850) or press the

temperature (TIC) and internal pressure (PIC) control of the
sterilisation cycle.
The page shows the process value (PV) and setpoint (SP)
values of both PIDs in numeric format, while two distinct
Bar graphs display the 2 PID control value percent. Setpoint
values can be edited from the page.
The page also displays the temperature of the product
(Food temperature).
Also on the page there are two components (ON/OFF but-
tons) to control pump pressure and the main motor.
5.1.3.
The controller controls the processing temperature via a
PID (TIC), using the highest of the two T01 and T02 tem-
peratures read in the kiln as the reference temperature. One
of the two values read are selected with a Selection Logic
Function (MAX).
The page shows the values of process value (PV) and set-
point (SP) in numeric format, while 3 Bar graphs graphically
display the two PV and SP values and the PID (OUT) control
value percent. The setpoint value is editable from the page.
The page also displays the temperature (Material Tempera-
ture) of the material being processed.
Also on the page are two components (ON/OFF and Open/
Close buttons) for air recirculation inside the kiln (Main Fan)
and to open and close the material door (Door ).
