RYMASKON 200-Modbus
Modbus Slave User Manual
When the device powers up, it enters DISPLAY-mode and it will display the first display value. When pressing
the MENU-button the next value will be shown. First all active display values and then all active set points are
displayed. After the last set point, the display will show the first display value again.
EDIT-mode is entered by pressing the MENU-button for more than 3 seconds. To enter the administration-mode
as system administrator two additionally defined buttons (TB0 and TB4) need to be pressed along with the
MENU-button for more than 3 seconds. Also in EDIT-Mode a short press on the MENU-button is used to go to
the next value. Any other button that has no specific function can be used in EDIT-mode to cycle the values in the
opposite direction. EDIT-mode is left when pressing the MENU-button for more than 3 seconds.
It is possible to edit the device settings in administration-mode.
CALIBRATION-mode will be entered for any display value when pressing one UP- and one DOWN-button
simultaneously for more than 3 seconds to adjust the offset. This mode is secured by the system administrator
password. CALIBRATION-mode is left when pressing the MENU-button for more than 3 second or after a
timeout of 1 minute.
An overview of all possible operating modes is given in Table 4 below. The operating mode can also be defined
by the Modbus master by writing the user interface direct access register (see Table 13 on page 23).
