1-1-3 Using the Keys
This section describes the basic functions of the front panel keys.
PF (Function (Auto/
Manual)) Key
(E5AN/EN Only)
This is a function key. When it is pressed for at least 1 second, the function set
in the PF Setting parameter will operate.
Example: When A-M (auto/manual) is selected in the PF Setting parameter
(initial value: A-M), the key operates as an auto/manual switch, switching
between Auto Mode and Manual Mode. If the key is pressed for more than 1
second (regardless of key release timing), the mode will switch.
O Key Press this key to move between setting levels. The setting level is selected in
the following order: operation level: adjustment level, initial setting level, com-
munications setting level.
M Key Press this key to change parameters within a setting level.
The parameters can be reversed by holding down the key (moving one per
second in reverse order).
U Key Each press of this key increments the value displayed on the No. 2 display or
advances the setting. Holding the key down speeds up the incrementation.
D Key Each press of this key decrements values displayed on the No. 2 display or
reverses the setting. Holding the key down speeds up the incrementation.
O + M Keys Press these keys to change to the protect level. For details on operations
involving holding these keys down simultaneously, refer to 1-3 Setting Level
Configuration and Key Operations. For details on the protect level, refer to
SECTION 5 Parameters.
O + U Keys
O + D Keys
To restrict set value changes (in order to prevent accidental or incorrect oper-
ations), these key operations require simultaneously pressing the O key
along with U or D key. This applies only to the parameter for the password to
move to protect level. (Refer to page 162.)
