BASE UNIT AND EXTENSION CABLE
POINT
* 1: If these stage numbers are set, a "BASE LAY ERROR" (error code: 2010) occurs.
* 2: The extension base unit can be connected only when the first 5 digits of serial No. of the
Redundant CPU is "09012" or later and the redundant system is configured.
The extension base unit cannot be connected when the first 5 digits of serial No. of the
Redundant CPU module is "09011" or earlier.
* 3: Connect the Q6 WRB to the first extension stage. Since the Q6 WRB is fixed to the first
extension stage, stage No. setting is not required.
* 4: The Q6 WRB cannot be connected to the second extension stage or later stages. Use the
Q6 RB for the second extension stage or later stages.
1. For the stage number setting connector, set the number matched with the
extension stage number.
Do not set the same stage number at two or more positions or do not fail to
set a number. A miss-input or miss-output may occur.
2. In case of using the QA6ADP+A5 B/A6 B, be sure to set the same stage
number to both the stage number setting connector of the A5 B/A6 B and
that of the QA6ADP.
