4. Simultaneous operation system individual setting
It is easier if the optional remote controller is used when setting the slave unit.
•
Perform the following procedures when setting the master and slave unit separately.
Procedure
(1)
Change the SECOND CODE NO. to “02”, individual setting, so that the slave unit can be individually
set. ( Refer to Table 8 )
(SECOND CODE NO. is factory set to “01”, unified setting.)
Table 8
(2)
Perform field setting for the master unit.
(3)
Turn off the main power supply switch after (2).
(4)
Detach remote controller from the master unit and connect it to the slave unit.
(5)
Turn on the main power supply switch again, and as in (1), change the SECOND CODE NO. to “02”,
individual setting.
(6)
Perform field setting for the slave unit.
(7)
Turn off the main power supply switch after (6).
(8)
If there is more than one slave unit, repeat steps 4 to 7.
(9)
Detach the remote controller from the slave unit after the setting, and reattach to the master unit. This
is the end of the setting procedure.
* You do not need to rewire the remote controller from the master unit if the optional remote controller
for slave unit is used.
(However, remove the wires attached to the remote controller terminal board of the master unit.)
