Setting Knobs
Note: 1.
Use either a solid wire of 2.5 mm
2
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.
Recommended ferrules

Meaning
Power indicator
(PWR: Green)
Lit when power is being supplied.
Relay status indicator
(RY: Yellow)
Lit when relay operates (Not light when both
AL1 and AL2 are in error status) (Normally
lit)
Alarm indicators
(AL1 and AL2: Red)
Lit when there is an overvoltage or
undervoltage.
The indicator flashes to indicate the error
status after the input has exceeded the
threshold value while the operating time is
being clocked.
Item
Usage
Voltage knob (AL1)
Used to set the voltage to 10% to 100% of
maximum measuring voltage.
Voltage knob (AL2)
Used to set the voltage to 10% to 100% of
maximum measuring voltage.
Operating time knob (T) Used to set the operating time to 0.1 to 30 s.
For 2.5 mm
