Other current sensors (CT)
• When using the CTL-12-S36-8 current sensor (CT), set CTL-12L-8 (0.0 to 100.0A) (0).
• When using the CTL-6-P current sensor (CT), set CTL-6-P-H/CTL-6-S-H (0.00 to 20.00A) (1).
■Enabling the settings
Turn ON and OFF 'Setting change command' (YB) in the setting mode ('Setting/operation mode status' (X1): OFF) to enable
the settings.
■Occurrence of a write data error
When a value out of the setting value is set, a write data error (error code: 1950H) occurs. 'Error flag' (X2) turns ON and the
error code is stored in 'Latest error code' (Un\G0).
■Default value
The default value is CTL-12L-8 (0.0 to 100.0A) (0).
