Indicators

Note: The input across L1 and L2 is used for the internal power

supply. Therefore, the power indicator will not be lit if there is no

input across L1 and L2.

Setting Knobs

insulating sleeve for the terminal connection.

The length of the exposed current-carrying part inserted

into the terminal must be 8 mm or less to maintain dielectric

strength after connection.

Meaning

Power indicator

(PWR: Green)

Lit when power is being supplied (see note).

Relay status indicator

(RY: Yellow)

Lit when relay is operating (normally lit).

Alarm

indicator

Overvoltage:

Red

Lit when there is an overvoltage.

The indicator flashes to indicate the error status after

the overvoltage has exceeded the threshold value

while the operating time is being clocked.

Undervoltage:

Red

• Lit when there is an undervoltage or phase loss.

The indicator flashes to indicate the error status

after the undervoltage has exceeded the threshold

value while the operating time is being clocked.

• Lit when there is a phase sequence error.

Usage

Overvoltage knob

(OVER)

Can be set between

−30% and 25% of the rated

input.

Undervoltage knob

(UNDER)

Can be set between

−30% and 25% of the rated

input.

Operating time knob (T) Used to set the operating time to 0.1 to 30 s.
