Number of units in combination as shown above is applicable to when the units being controlled by each central control are not
duplicated.
In case of managing one unit with plural central controls (SC-SL4-AE2, SC-SL4-BE2, SC-SL2NA-E), be sure to make permission
/ prohibition setting only with a master central control, not with other central controls.
When using an external input (emergency stop, demand), input the external signal to the master central control.
In addition, make this setting to “valid” when the external input wiring such as emergency stop or demand input are connected to
the master central control.

Notes (1) Denition of New and Previous Superlink (New and Prev. SL)
New Superlink (New SL) :
In case that all units connected to the network are models compatible with New Superlink (KXE6 model or newer, and
type-N or newer of Central control and Interface), and the SL settings are in factory default (“New SL” or “AUTO”).
Previous Superlink (Prev. SL) : In case that even a single unit connected to the network is not compatible with New SL (KXE4 model or
older, and older than type N of Central control and Interface), SL setting is required.
(2) In case of managing one unit with plural central controls (SC-SL4-AE2, SC-SL4-BE2, SC-SL2NA-E), regarding the prohibition setting
of remote control if the different settings from plural central controls are done on this unit, it may cause that this unit cannot start
operation by the remote control despite the intention of user. Accordingly, in this case, be sure to make permission / prohibition setting
only with the master central control, not with slave central controls.
In addition, make this setting to “valid” when the external input wiring such as emergency stop or demand input are connected to this central control.
(3) Number of units in combintions;
SC-SL4-AE2, BE2 1, 2 1, 2 1, 2
SC-SL2NA-E 0 - 2 3, 4 5 - 8
