Description

Make sure that the item number "730" is
9
displayed 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.
Instead of "oF" (disabled), select "on" (enabled)
10
for forced operation in the item data box.
Then, the figure shown in the lowest digit of the
item data box, which indicates the number of
contacts selected for forced operation, will be
added by one.
11
When the SELECT/SET switch is pressed
then for programming, the item No. box will start
blinking, instead of the item data box.
In this case, the SET.END/TRIP indicator LED
still remains blinking, which means that the
specified forced operation has not been
executed.
- To execute forced operation of the selected
12
contacts, press the SET.END/TRIP switch.
Forced operation will be performed only while
this switch is depressed.
During forced operation, the figure shown in the
lowest digit in the item data box which indicates
the number of contacts selected for forced
operation is blinking. Also, the operation
indicator LEDs that correspond to the selected
programmable contacts come on.
When the SET.END/TRIP switch is
released, the indication of contact operation,
item No. and data will end. Also, the data
programmed for forced operation in the step
above will be all cleared. However, the
operation indicator LEDs will remain the same
status.
To extinguish the operation indicator LED
lamps, press the RESET switch.
- To terminate the procedure without executing
forced operation, press the
SETTING/CANCEL switch to delete all the
data programmed in the step above.
