Inside blinder setting in ohms
Note 1: For 5 A relay. Setting and step are a factor of 5 lower for 1 A relay.
Note 3: These settings have a "OUT" option for disabling a corresponding function.
Note 4:
The impedance setting. The setting ranges shown are for 5 A ct. The displayed setting range is multiplied by 5 if a 1 A ct is
used (CTYP = 1).
Note 5: 9600 bps Audio Tone option.
Note 2: These settings have a "BLK" option for disabling a corresponding function.
Note 6: 56/64 kbps Digital Communication option.
Note 7: Only if optional extended output is included.
Note 8: Only if optional backup system is included.
