the ON button on the main unit AT panel, and press the Lo or Hi button.
5.1.3 Remote Operation
•
For on/off switching via remote operation, short-circuit pins
④
and
⑧
.
Pin
①
is short-circuited

ON
Pin
①
is not short-circuited


•
Do not short-circuit between pins
④
and
⑧
when taking signals by on/off switching on the device
side.
Take out desired output signals as per the description in
“5.1.2
Color and signal of each wire
”.
•
Storing the performance level in the memory
By recording the performance level in the memory using the OFF button on the main panel, you can
start the operation at the stored performance level.
However, when the operation is stopped by turning off the main power switch, recall the performance
level stored with the OFF button by pressing the ON button once on the AT panel of the main unit.
