Hysteresis is set using the hysteresis knob (HYS.)
The setting range is 5 to 50% of the operating value.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the hysteresis.
Example: Maximum of 200 A AC, Current Setting (SV) of 50%, and Overcurrent Operation
The operating time is set using the operating time knob (T).
The operating time can be set to between 0.1 and 30 s.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the
same level.)
Use this as a guide to set the operating time.
If the input current exceeds (drops lower than) the current setting, the alarm indicator will start flashing for the set period and then stay lit.
The startup lock time is set using the startup lock time knob (LOCK).
The startup lock time can be set to between 0 and 30 s.
Turn the knob while there is an input to the input terminals until the alarm indicator flashes
(when the set value and the input have reached the same level.)
Use this as a guide to set the startup lock time.
The startup lock time will start when the input current reaches 30% or more of the current
setting.
Use startup lock time to prevent unwanted operation, e.g., as a result of inrush current.
Operation will be at 100 A and resetting at 90 A when the hysteresis (HYS.) is set to 10%.
