Nomenclature
Front
Note: Use solid wires, stranded wires, or ferrules to connect to the
terminals.
To maintain the withstand voltage after connecting the
terminals, insert 8 mm of exposed conductor into the terminal.

Item Meaning
Power indicator
(PWR: Green)
Lit when power is being supplied.
Output status indicator
(Output: Yellow)
Lights for output
Alarm indicator
(ALM: Red)
Lit when there is an overcurrent or
undercurrent.
The indicator flashes to indicate the error
status after the input has exceeded the set
value while the operating time is being
clocked.
Item Usage
Current knob (SV)
Used to set the current to 10% to 100% of
maximum setting range.
Hysteresis knob (HYS)
Used to set the rest value to 5% to 50% of
the operating value.
Operating time knob (T) Used to set the operating time to 0.1 to 30 s.
Startup lock time knob
(LOCK)
Used to set the startup lock time to 0 to 30 s.
