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.

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.
