„

1. Response speed setting

The response speed is the time from when the sensor head starts detection

until the value at the detection position is established as a comparator value.

* "20" for GV-H1000 (L) only.

„

2. Output mode setting

Sets the control output mode for each control output.

N.O. (normal open) and N.C. (normal close) operate in the following

manner.

„

3. Operation mode selection

Sets the operation mode.

„

4. Clamp function setting

Set the operations when distance detection cannot be performed (such as

when the detection object does not enter the detection range, or when there is

insufficient light intensity).

„

5. (6.) Delay timer setting

Individual delay timers can be set for channels 1 and 2.

„

7. Hysteresis setting

Sets the hysteresis for judgment with control outputs 1 and 2.

The hysteresis setting range and default value are as follows when "Usr" is

selected.

„

8. External input function setting

Sets the function assigned to the external input (pink line).

The minimum external input time is 20 ms.

z

External shift input

When external input is input, the current value is shifted by the value set for shift

target value.
(For information about the shift target value, see "9. Shift target value setting".)

z

Bank switching input

When keylock is set for the amplifier, the bank switches with input to the external

input.
(For more information about bank switching, see "Bank switching".)

When edge hold mode (A-1 mode) is set, switching banks with the external
input resets the current value to 0.

z

Timing input

Comparator output is only output over control output 1 when external input is

on.

The timing input indicator on the sensor amplifier lights up.

Control output 2 continues to output comparator output, regardless of

whether timing input is on or off.

Setting item

Description

Default value

on

Outputs the comparator output with the
detection value obtained immediately before
the distance was judged to be not detectable.
The current value display and LED bar
display are also saved for the immediately
preceding value.
If distance detection can be performed, then
the hold is released.

oFF

When the distance detection cannot be
performed and "---" is displayed, the
comparator output operates in the same way
as if a detection object appears at the
farthest point of the detection range.
