CT1 CT selection [Q compatible mode]
Select the current sensor (CT) to be connected to CT1 in the Q compatible mode.
■Setting range
• 0: CTL-12-S36-8 (0.0 to 100.0A)
• 1: CTL-6-P(-H) (0.00 to 20.00A)
• 2: CT ratio setting (0.0 to 100.0A)

■Setting current sensors (CT) and buffer memory areas
When using a current sensor (CT) other than the CTL-12-S36-8 and CTL-6-P(-H), set the number of second-winding (turns) of
the current sensor (CT) to be connected in 'CT1 CT ratio setting' (in the Q compatible mode) (Un\G288). Set the following
buffer memory areas as follows according to the specifications of the current sensor (CT) to be used:

Other current sensors (CT)
• When using the CTL-12-L-8 current sensor (CT), set CTL-12-S36-8 (0.0 to 100.0A) (0).
• When using the CTL-6-S-H current sensor (CT), set CTL-6-P(-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.
