Output code 2 : All relays turn OFF.

Output code 3 : All relays turn ON.

Output code 5 : Terminals 3 – 9, 5 – 8 turn ON.

LINEARIZATION

■ Linearization Types

Linear: No linearization

Square root: The input is square root extracted.

User table

Calibration points: Max. 128 points; the input % and

linearized value in scaling are specified in pairs.

Selectable range: -7.5 to +107.5 % as input %; -9999 to

+9999 as linearized values

■ Low-end Cutout: Low-end cutout (Low Cut) point

selectable within the range of 0 to 100 %.

With the linear or user table output type,

the output signal is forcibly set to 0 % for the input lower

than the low-cut point. With the square root extraction, the

output signal is linear to the input when the latter is lower

than the low-cut point.

INSTALLATION

Power consumption

•AC: Approx. 5 VA at 100 V

Approx. 7 VA at 200 V

Approx. 8.5 VA at 264 V

With 4-point alarm type, leave extra 1-unit space on both

sides of the unit if all 4 relay coils are to be energized in

normal conditions.
