Operating Time
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 set value, the alarm indicator will start flashing for the set period and then stay lit.
●
Startup Lock Time
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 set value.
Use startup lock time to prevent unwanted operation, e.g., as a result of inrush current.
