HMI function instruction
1.
HMI can display character, built-in Chinese, user-defined Chinese and GSM telephone number. This
information can not be edited through keypad.
2.
HMI can display function current value (T, C, R, G and DR), analog input/output value (A, AT, AQ). This
information can not be edited through keypad.
3.
HMI can display preset value of function (T, C, R, G and DR). This information can be edited through
keypad.
4.
HMI display state of coil (I, X, Z, M and N), state of M and N can be edited through keypad.
5.
Once more than one HMI enabled at the same time, press changing page button to display other HMI
screen.
6.
When another HMI is enabled, SG2 can auto-determine whether does HMI screen display the present page
or change to the new HMI screen; it depends on the HMI code. For example, HMI keeps H01 screen as the
present screen even though H02 coil be exercised.
