SET/ENT
SET/ENT Switch
This switch is used for changing over displays of
screens and items. It is also used for registration of
set values and adjusted values. Pressing the
switch for 3 seconds or more changes over the dis-
plays for measured value, parameter setting, or
input/output adjusting.
12
Range Switch
This switch is used for changing over display of
phases. It is also used for shifting digit position and
decimal position of set values on parameter setting
display.
13
Figure UP switch
This switch is used for the followings:
1. Increase the set value on parameter setting
display.
2. Display the maximum value of voltage or cur-
rent.
3. Increase the adjusted value at input/output ad-
justment. I
14
Figure DOWN switch
This switch is used for the followings:
1. Parameter decrement at parameter setting.
2.
Display the minimum value of voltage or current
3.
Decrease the adjusted value at input/output adjust-
ment
