Block for operation

Block for charging

(4)Notes on using K control models

When using a K transmission converter (model name: PAC-SC25KA, PAC-SC25KAA(-E)) to manage K control models, take note of the following. See the documentation provided with the Ktransmission converter for more detail.

•The address of the K transmission converter will be the smallest address of the K control model + 200.

•Set the K control model addresses so that they are larger than the M transmission model addresses.

•When setting a group containing K control models, make the group number the same as the smallest unit address in the group.

(5)Notes on using A control mode

•Use the A/M NET Adapter (model name: PAC-SF48MA(-E)). Set the group to “Group with only A control”.

(6)Countermeasure when an error occurs

•Note that each control or function may not operate properly when rebooting (*1) or when a fault occurs in the centralized Controller G-50A. Since each error is displayed when it occurs, it is recommended to solve the faults quickly.

*1 Indicates that the system is restarting.
