GT2-500-M-E
Functions that can be set using DL Series Communication Units
See the GT2-70 Series user manual for information about each
function.
See the DL Series manuals for information on using the
Communication Units.
The user manuals for DL Series Communication Units and the GT2-70
Series can be downloaded from the KEYENCE website.

Listed below are the main functions of the GT2 Series and where to
find information about them in the GT2-70 Users Manual.
See the GT2-70 Series user manual for information about the items
listed below.
Troubleshooting
When there is a malfunction, the status light on the sensor amplifier
lights in red.
If you are using a DL Series Communication Unit (excluding DL-RB1A),
details of the error can be checked via the Communication Unit. See
the DL Series manuals for information on using the Communication
Units.

Problem Cause Corrective action
Sensor head
error
• The sensor head is
disconnected.
• The sensor head cable is
broken.
• The sensor head is
damaged.
• Connect the sensor
head.
• Replace the sensor
head cable.
• Replace the sensor
head.
EEPROM
error
• Failed to write data.
• Turn the equipment off
and on, and perform
initial reset. (If this
does not solve the
problem, the
equipment may be
damaged, or may have
reached the end of its
service life. Replace
the amplifier unit.)
Jam
detection
error
• The spindle is jammed.
(When using the jam
detection function)
• If the spindle is
jammed and does not
move, replace the
sensor head.
Use a Communication
Unit to check that the
timing input is
appropriate.
Self timing
delay error
• The value fell below (rose
above) the timing level
during the set delay time.
• The value fell below (rose
above) the timing level
before the detection status
was stable and the
criterion level (P.V. value)
was fixed when using
static hold internal timing.
• The value rose above (fell
below) the timing level,
then fell below (rose
above) the timing level
before the criterion level
(P.V. value) was fixed when
using delay timer internal
timing.
• Make sure that the
value does not fall
below (rise above) the
timing level before the
criterion value is fixed.
Alternatively, lengthen
the static hold delay
stabilizing amplitude
so that the criterion
value can be easily
fixed.
Unit number
error
• When using the calculation
function, the number of the
expansion unit when the
power is turned ON differs
from the number of the
expansion unit in the
memory of the main unit
when the calculation is set.
• When using the calculation
function, a model other
than the GT2-500/70
Series is added.
• Reset the calculation
mode or perform initial
reset of the main unit.
Perform initial reset via
the Communication
Unit. See the DL
Series manuals for the
method.
Calculation
error
• When using the reference
difference calculation
function, an error occurred
in the main unit.
When using other than the
reference difference
c
alculation function, an
error occurred in an
expansion unit.
• Check each main/
expansion unit for the
cause of the error.
Calculation
only mode
error
• The sensor head is
connected to the main unit
in which the calculation
only mode is set.
• Remove the sensor
head from the main
unit or set a mode
other than the
calculation only mode.
