BASIC OPERATION
Normal Operating Mode
In the normal operating mode, the timer value is shown on the main
display. By successively pressing the
A
key, the accessible presets or
output time values can be viewed in the secondary display.
Each of these values can be independently programmed to be viewable
only, viewable and changeable, or locked (not viewable) in the normal
operating mode. If all values are locked, the secondary display will be
blank. Only from the normal operating mode can access be gained to the
Programming Menu or Protected Value Menu.
Modifying A Secondary Display
Parameter From the Front Panel
Secondary display parameters can be modified from the normal
operating mode if the Operator Access privileges allow it.
To modify a parameter, it must be viewed in the secondary display.
When the parameter to be modified is viewed, press the
B
or
C
key.
Leading zeros appear and the least significant digit blinks. The value can
now be modified as described in Programming Numeric Data Values, page
12.
Protected Value Menu
The Protected Value Menu allows access to selected presets and output
time values without having them viewable or changeable from the main
display. To enter the protected menu, the
A key is pressed and held, and a
code value is entered. The Protected Value Menu and the Programming
Menu are not available at the same time. See Front Panel Accessible
Functions With Program Disable, page 11, for available options.
Access value parameters that are programmed for “P” or “n” are
accessible in the Protected Value Menu. Parameters selected as “n” (no) are
viewable from the main display, but can only be changed in the protected
menu. Parameters selected as “P” (protected) are not viewable from the
main display, but can be viewed and changed in the protected menu.
