concerning to transmission delay time.
The transmission delay within the entire system depends on the scan time achieved by
the PLC unit and on other devices included in the network.
Solenoid valve responding time, of course, varies depending on model. It is advisable of
referring to valve specification.
As for OFF time, there is another delay factor of approx. 20ms due to flywheel diode be-
ing used for surge absorbing circuit to valve slave station.
3. OPERATION
3.1 Switch setting
The switches are used for four different kinds of setup: setting the station number, set-
ting the transfer rate, specifying whether to hold or clear the output during an error,
and specifying the end station. Since different switches are used for different kinds of
setup, you must correctly identify the switch to be used. Before changing the switch
positions, be sure to cut the power.
Setting the switches
Set the switch always with the serial transmission unit block

.
The serial transmission unit block cover can be opened and closed
at one touch.
Except when the switch is set, be sure to keep the cover closed;
otherwise, foreign matter may intrude into the internal circuit part
from the cover unit, thus resulting in failure or malfunctioning, and
also causing damage to the cover.
Even during setting, take special care so that foreign matter or
particle does not enter the interior.
The setting switch is precision made; rough handling may, there-
fore, cause damage thereto. Also absolutely avoid touching the
internal circuit board during setting.
