MMI (Man Machine Interface)
On the front panel there are eight buttons which allow the user to perform all the settings, reading
and modification operations.
The adjustment of the settings and the operation mode of the output relays must be performed while
the unit is electrically powered;
All preset values are permanently stored in the nonvolatile memory.
The buttons take the following operations:
-
(Up) move the cursor upwards to the preceding menu options
-
(Down) move the cursor downwards to the subsequent menu options
-
(Left) move the cursor upwards to the preceding menu options
-
(Right) move the cursor downwards to the subsequent menu options
- (Enter) access to the selected menu with the option of modifying any given parameter
-
(Reset) abort the current changes and/or accessing the previous menu

Reading variables (READ)
All data (measure, settings, parameters, etc...) can be displayed; they are arranged in functional
group submenus.
Setting modifying (SET)
For security reasons it is sometimes requested that any change of the settings using MMI is di-
sabled. In this way only qualified personell will be able to modify settings using software ThyVisor.
Changes can be made with MMI only if the parameter “Enable Settings by MMI” is active. (SET\
MMI\PARAM SETTINGENABLE) This parameter is changeable only using program.
To effect a change, having identified the parameter intended for change, the following procedure
must be performed:
• Select the parameter going through the menus by means the Up, Down and Right keys
• Press theEnter button for a few seconds; the modification in progress status is highlighted by fla-
shing of the 51-51N, 67NLEDs and by appearance of the pointer on the bottom.
• Move the cursor over the parameter intended for change using the Enter.
• Change the parameters by means the Up(increment) or Down (decrement).
