Step
Description
Make sure that the item number "810" is shown
5
in the box, and press the SELECT/SET switch.
The item data box will start blinking, instead of
the item No. box, so that data can be changed.
Use the UP switch to change data from "0010"
6
to "001F".
In this case, the data should be input in such a
way that individual letters are put separately
from the lowest digit to the higher sequentially.
Make sure that the desired value is shown in
7
the item data box, and press the SELECT/SET
switch for programming. In this case, the
operation indicator LED according to the
condition programmed here will come on. So,
check if the LED indication matches the
condition you want to set.
When it is detected that new data has been
programmed to be ready for replacing the
currently used setting, the SET.END/TRIP
indicator LED will blink.
At the same time, the item number box will start
blinking instead of the item data box.
Note that the setting being used for the current
operation is still valid even if another value has
been programmed in the item data box.
- To put the new data into effect, press the
8
SET.END/TRIP switch. The currently used
setting will be replaced by the new data
programmed to complete the procedure.
- To cancel the new data, press the
SETTING/CANCEL switch to delete all the
data programmed in the step above.
