Through-beam Sensor Heads: FUN Mode Functions Section 3-8
105
3-8-13 Limiting the Number of Display Digits
The number of display digits of the main display and sub-display can be
set. When the number of digits is reduced, the lowest digit is disabled first.
In addition, if 0 digits are specified, the entire digital display is disabled.
This applies, however, only in RUN Mode.
3-8-14 Setting for Non-measurement
The output method used during non-measurement can be set. This setting
applies when the reset is input or a reception error occurs.
Maximum output voltage: Approximately 5.5 V
Maximum output current: Approximately 23 mA
Refer to 4-5-12 Other Special FUN Mode Settings.
3-8-15 Zero Reset Memory Function
If required, the zero reset level can be stored when the power supply is
turned OFF. Enable this function when the previous zero reset level must
be restored when the power supply is turned ON again.
When this function is enabled, the zero reset level data will be written in
nonvolatile memory (EEPROM). The EEPROM can be written a maximum
of 100,000 times. Therefore, disable this function in order to preserve the
memory when using the zero reset for every measurement.
Even when the zero reset memory function is disabled, the zero reset level
will be rewritten to EEPROM at the following times.
• When the threshold values are set.
• When settings are performed in FUN Mode.
3-8-16 Gain Switch
The gain can be set to select the reception sensitivity (corresponds to the
internal gain). The gain should normally be set to METAL.
Note: If an appropriate value is not set as the gain for the sensing object color,
distance, etc., the output may soon saturate and reach non-measure-
ment status.
Outputs Setting for non-measurement
CLAMP KEEP
Judgement outputs All OFF. The status immediately
before measurement
stopped is held.
Linear output Held at the maximum
output value.
