Controller settings

Overlap ‘Controller settings’ allows modifying basic parameters, including date and time, display unit parameters or sounds.

Date and time

Entering  ‘Date  and  time’,  we  successively set pulsating
parameters  according  to  guidelines  provided  on  the  left
side. Required value is selectable with arrows.
Then,  we  proceed  to  the  next  item  using the OK
pushbutton.

Display unit

Display unit parameters allow changing screen backlight brightness (1-10, darkest / brightest).
The second parameter is setting of inactivity time until backlight dimming - the screen will get dimmed if user does not touch any
keys for preset time.

Sounds

Sound  parameters  allow setting  keyboard  sound (if  set  to  YES - we  will  hear  characteristic  sound  when  pressing  controller
operation pushbuttons). The sound of alarms indicates an acoustic signal when faulty equipment operation is detected.

RS485 port

It is an interface used for data acquisition or controlling the unit through an external controller. Master device decides about the
settings of transmission rate, and physical and logic address.

Language

It is possible to choose the language for communication with the controller from among those available in the database (Polish,
English, German).
