5-8. Activating output when turning on power
Using the output on/off function with the external contacts shown in
Section
“5-7-4. Output ON/OFF with external contacts”, it is possible to
turn on output automatically as soon as power is input to the power
supply unit.
※
The value stored automatically when the source voltage is cut
off or the POWER switch is shut off is output. Check the set
value again before using this function.
5-9. Usage of sequence Function
Using the sequence function shown in Section
“5-5-5. Sequence
function(05)
”, it is possible to execute the sequence programs written in
the power supply unit in advance through the optional interface board
on the power supply unit without the need of any other devices. See
Section
“5-5-5. Sequence function(05)” above for the procedures of
setting the sequence operation.
Download the application software exclusive for the sequence
operation from our homepage and create sequence programs in
advance.
(1) Write sequence programs through the interface board.
(2) Activate the sequence function shown in Section
“5-5-5. Sequence
function(05)
”.
(3) Execute sequence operation with the
PRESET
key(s).
Each
PRESET
key has two functions. Operations caused by
pressing the
PRESET
keys and
OUTP
ＵＴ
key are different in the normal
operation and sequence operation modes. These keys cause the
following operations in sequence operation.
