4-3. Screeen configuration
In the SR70 series controller, the screen configuration is divided into screen groups and screens corresponding to the frequency of usage in their
operation.
(1) Mode 0 screen group
It is made up of screens of relatively high frequency in use for operation, i.e., the basic screen (for setting target value and confirming current
measured value), the auto tuning action control screen and the alarm setting screens.
(2) Mode 1 screen group
Made up of screens of less frequency than those of mode 0 group, i.e., screens for setting values to be changed as required by input conditions or
control capability and a screen for locking items not to be changed.
(3) Mode 2 screen (function slecting screen)
Once items are set in this screen, the need to change them seldom arises; selected code of measuring range, selected output characteristic, slected type
of optional alarm functions, and selected action mode of heater break alarm are displayed on this single screen.
(4) Method of changing data
Press the
or
key to change data in each screen and press the
