6 Buffer memory
6.2 Configurable sections (Un \ G0 to Un \ G1100, Un \ G2000 to Un \ G2100)
6.2.1 Phase wire system (Un \ G0)
Phase wire system for target electric circuits is configured.
It is common for both CH1 and CH2.
(1) Setting procedure
(a) Set the phase wire in the buffer memory. Setting range is as follows:
(b) Turn Operating condition setting request (Yn9) from OFF to ON to enable the setting. (Refer to
5.2.2(5).)
(2) Default value
It is set to 3 (Three-phase 3-wire).
6.2.2 Leak current, Leak current for resistance multiplying factor (Un \ G100)
Stores the measured value of multiplying factor for leak current and leak current for resistance.
(1) Details of stored data
(a) It depends on the measuring mode (low sensitivity mode and high sensitivity mode).
For the setting of Measuring mode, refer to section 7.6.2 or 7.7.2.
(2) Default value
It is set to 0. (Low sensitivity mode: 10
6.2.3 Io1 primary alarm value (Un \ G1000)
Set the monitoring level of CH1 leak current.
For the buffer memory address of other monitoring value, refer to section 6.1(1).
(1) Setting procedure
(a) Set the monitoring value in the buffer memory. Setting range is as follows:
Low sensitivity mode: 1 to 1000 (mA)
High sensitivity mode: 1 to 10000 (×
(b) Turn Operating condition setting request (Yn9) from OFF to ON to enable the setting. (Refer to
5.2.2(5).)
(2) Default value
All monitoring values are set to 0 (no monitoring).
