Power indicator

(PWR: Green)

Relay status indicator

(RY: Yellow)

Alarm indicator

(ALM: Red)

Meaning

Lit when power is being supplied.

Lit when relay is operating

Usage

Voltage knob (SV)

Used to set the voltage to 10% to 100% of

maximum measuring voltage.

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.

Note: 1. Use either a solid wire of 2.5 mm2 maximum or a ferrule with

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.

For 2.5 mm2 or

smaller solid wires

For ferrules with

insulating sleeves

8 mm max.

Recommended ferrules

Phoenix Contact

• Al 1,5-8BK (for AWG16)

• Al 1-8RD (for AWG18)

• Al 0,75-8GY (for AWG18)

2. Tightening torque

Recommended: 0.49 N·m

Maximum: 0.54 N·m

8 mm max.
