Appendix

When the judgment value (P.V.) is "-----" the judgment output becomes all OFF (When

Normally Open is set), and the analog voltage output is 5.5 V and the analog output current

is 3.0 mA.

“5. Output State” (page 4-14)

“10. Analog Output Scaling” (page 4-27)

In cases other than the above, the judgment output and analog output keeps the output status

immediately before the output.

Additional setting

error

When using the calculation

function, a model other than

IL-1050 or IL-1550 is mounted

next to the main unit, or there

is no expansion unit.

• Check the type of sensor amplifier after the

power is turned OFF.

• Turn the power OFF and then connect the

expansion unit.

Calculation error

While using the calculation

function, an error is found on

the expansion unit (expansion

unit 1) added next to the main

unit.

Solve the error on the expansion unit 1.

Reference

If the internal measurement value (R.V.) becomes [-----] because the

target is out of the measurement range, the internal measurement value

(R.V.) retains the value immediately before the target disappears for the

period the response time elapses. After the response time elapses, the

internal measurement value (R.V.) becomes [-----].

“3. Averaging rate, Step count filter, High-pass filter” (page 4-9)

Display Description Corrective actions

The internal

measurement

value (R.V.) is

displayed as

[-----].

A target is not in the

measurement range.

A target cannot be measured.

Adjust the target to correctly fall within the

measurement range.

The laser emission stop input

is ON.

Set the laser emission stop input to OFF.

Check the wiring of the laser emission stop

input.

“11. External Input” (page 4-30)

The judgment

value (P.V.) is

displayed as

[-----].

The hold function is used and

the judgment value (P.V.) is

held.

Check the hold function setting.

Input the timing input according to the setting.
