Temperature sensors S1, S2, S3, S4 can be of Rsxxx1k5 (low temperature) or KSxxx1k0 (high
temperature type). The sensor type for each input is configured through Se1, Se2, Se3, Se4 parameters
of Config submenu.
RSxxx1k5 sensors are not polarized while KSxxx1k0 sensors are polarized. Correct KSxxx1k0
sensor connection should be assured by connecting the blue colored lead of sensor to the odd
numbered terminal (i.e. 1, 3, 5, 7).
Insert probes into correct diameter sockets for better temperature reading response and improved
accuracy. Place the probes according to the selected configuration. For this reason consult the
corresponding diagram. The maximum distance between probe and device must not exceed 30m. The
connection must be done with conventional thready two-conductor cable with cross section i.e.1 mm.
Use always separate cables for probes and load or supply connections. Mixing low-level signal probe
cables and load or supply cables affects device performance. After the installation completion replace
the front cover of the electric enclosure and ensure that when the device is operable only the front touch
panel is user accessible.
Setup
The ULTRA device has luminous liquid crystal display in which the parameters and the messages are
shown. It also has three tactile keys that helps you to enter the appropriate settings. Familiarize your
selves with the front panel of the device as shown in Figure 2.
The display of the ULTRA controller has integrated screensaver functionality. If the keyboard
remains inactive for one minute the display switches off. During screensaver the ULTRA
controller operates normally. Press any key to exit screensaver mode.
Beside the right end of the display there is a three cell matrix. Every cell of the matrix correspond to the
right most character position of the display as shown in Figure 2. The displayed symbol indicates the
status of the corresponding relay. If the selected configuration does not use some of the relays the
respective display position remains blank.
During the normal operation the display looks like the Figure 3.
The left most symbol of the upper line represents the collector and the symbol exactly underneath
represents the store.
When the device is powered some introductory messages are shown in the display. Then the controller
begins to operate according to the factory presets.
To enter the values of your own press momentarily t
he “SET” key. The message “MENU” is then shown
at the first line. The second line shows the first allowable submenu option named “1.Config”. By
pressing the keys “
” and “
” you can see all available submenu options. There are 9 submenus.
When no key is pressed for some seconds the device returns from the submenu to menu and then to
the normal operation mode. The Table 1 shows the menu and submenu structure.

9. Exit
Closes the submenu and returns to the menu.
When in the desired submenu press the “SET” key to enter in. Being inside the correct submenu you
can choose from a set of available parameters. Scroll among these parameters using the “
” and “
”
keys. To modify the value of a parameter sim
ply press the “SET” key. Then the value starts flashing as
an indication of modify phase. You have only to enter the desired value by pressing the “
” and “
”
keys. Let then the device without pressing any key. The new value will be stored and you will return to
the corresponding submenu. If you need to store rapidly the new value upon the modification
completion you can press the “SET” key.
In the following tables the parameters of each submenu, a short explanation and the modification limits
are shown.
