Power indicator (Green)
Specifies whether channel selection is by panel operation,
by external channel select inputs, or through RS-232C com-
munication.
□PANEL: Selection is by channel select key.
□LOCK: Locks channel selection. In case of GD-C2, this is

Never use this product as a sensing device for personnel protection.
In case of using sensing devices for personnel protection, use products which meet laws and standards, such as
OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.
Make sure to use the sensor heads and controllers in the specified combinations. If they are used in any other com-
bination, the sensor heads may get damaged.

Function
Lights up when OUT-1 is OFF.
Blinks twice on completion of zero adjustment (0-ADJ.) or
SET-1 setting in SET mode.
Lights up when OUT-2 is OFF.
Blinks twice on completion of zero adjustment (0-ADJ.) or
SET-2 setting in SET mode.
Seven LEDs show the sensing level.
・More the number, thicker or larger the object sheets are,
more are the LEDs which light up.
LEDs light up one after the other during teaching.
All LEDs blink at the same time if the teaching fails.
・Shows the present channel (1 to 8).
Blinks during SET mode.
The decimal point informs whether the set level data has
been stored.

・The channel can be selected by the channel shift key when
CH-SELECT is set at PANEL.
・Sets the two-sheet threshold level (larger number of sheets).
・Sets the one-sheet threshold level (smaller number of sheets).
・Calibrates zero level under sheet non-existing condition.
・Switches between RUN mode and SET mode.
□RUN: Detection takes place.
□SET: Set-up is done.
・Switches timer mode.
□NORM. mode: Timer not used.
□OFD. mode: Delay timer (50ms approx.) used.

  • Page 5 Response time The controllers GD-C1 and GD-C2 automatically select the most suitable signal processing method, according to the material and thickness of the sensing object. Depending on the selected signal processing method, the response time is also automatically determined as either '5ms or less', or '30ms or less'.
  • Page 6: Specifications

    Notes: 1) Since it is possible that GD-3 may get damaged if controllers GD-C1 or GD-C2 are connected to it, make sure to use controller GD-C3 along with GD-3. The above detectable sheet thicknesses are typical data at the given sensing distance. The allowable thickness will differ from the range described in the above ta- ble at other setting distances.
