Yokogawa 414 Batch Controller - Manual (Page 32)

5. CALIBRATION
The Calibration routine enables the Setup Parameters to be programmed, as well
as enabling the input signals to be checked.
The calibration routine can be entered in two ways:
1 By connecting a wire link (or switch) to the rear terminal strip
across terminals 1 and 2 or,
2 By pressing the STOP key and while still holding, press the
DISPLAY key. Both keys must then be held for approximately 6
seconds. This second method of access can be disabled during the
calibration so that it is only possible to enter the calibration routine
via the link across terminals 1 and 2.
The key switch actions during Calibration are as follows:
RUN will change a flashing digit, to the next digit.
DISPLAY will increment a flashing digit or change a parameter
selection.
BATCH SET will reset a flashing digit to zero.
STOP will step through the program sequences.
Note that the arrows in the RUN and DISPLAY key switches indicate that these
switches can be used to change and increment digits respectively.
In stepping through the program sequence, the Parameter Description is always
displayed first, followed by actual value or parameter. When a value or
parameter can be changed, it is always shown as flashing, and the LED's in the
switch panels are lit if that key switch can be used to change a value.
