is turned ON.

Example: In this example, an All channels Alarm 1 OR output and an All
channels Alarm 2 OR output are output to the End Unit's auxiliary
outputs.
Note When assigning bus I/O, disable all bus I/O assignments first and
then make the settings.
4-7-4 Using G3ZA Multi-channel Power Controllers
Initial Settings The following procedure is required in order to use a G3ZA. The G3ZA cannot
be used in the condition in which it is shipped.
1,2,3... 1. Connect the G3ZA to a Basic Unit. Up to eight G3ZA Units can be connect-
ed to one Basic Unit. If more than eight Units are connected, a configura-
tion error will occur.
2. Turn ON pin 7 of SW2 on the Basic Unit, set SW2 on the G3ZA to 3
(57.6 kbps), and set SW1 on the G3ZA to between 0 and 15 (unit number).
The unit number of the G3ZA determines the MV sent from the Basic Unit.
For details, refer to Sending MVs to the G3ZA on page 105.
3. Turn ON the power supply to the Basic Unit and execute a Register Unit
Configuration: Reset operation command. No G3ZA Units are registered
in the default Basic Unit settings.
4. Turn OFF the power supply to the Basic Unit and then turn ON the power
supply in the following order: G3ZA Units and then the Basic Unit. When
the Basic Unit starts, it will automatically scan for connected G3ZA Units.
5. Check the Configuration Error A Status to see if any errors have occurred.
If there are no errors, execute a Register Unit Configuration: Register op-
eration command. The next time the Basic Unit is started, it will scan only
for the registered G3ZA Units, reducing the startup time.
Connection Example When the EJ1 starts, it scans the connected G3ZA Units and automatically
assigns names G3ZA1, G3ZA2, etc., in order starting with the lowest unit
number.
