Set model Nos. having the suffix 'I' are different frequency type.
These values are for a range which is 20 to 60% of the maximum sensing distance.
The length of the sensor head cable cannot be changed.
The given weight of the threaded type sensor head is the value including the nuts and the
toothed lock washer.
Take care that the output voltage is reduced due to the resistance of the wiring cable.

WARNING
CAUTIONS

Make sure that the sensor head and the amplifier which have the same
production serial number (7 digit) are used in combination. Since adjust-
ment is done before shipment, if items with different production serial
numbers are combined, the sensing characteristics will deteriorate even if
they have the same model Nos.

Make sure that the power supply is off while wiring.
Take care that wrong wiring will damage the sensor.
Verify that the supply voltage variation is within the rating.
If power is supplied from a commercial switching regulator, ensure that
the frame ground (F.G.) terminal of the power supply is connected to an
actual ground.
In case noise generating equipment (switching regulator, inverter motor,
etc.) is used in the vicinity of this product, connect the frame ground
(F.G.) terminal of the equipment to an actual ground.
Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway. This can cause malfunction due to induction.
Do not use during the initial transient time (0.5 sec.) after the power
supply is switched on.
The length of the sensor head cable cannot be changed.
Make sure that stress by forcible bend or pulling is not applied directly to
the sensor cable joint.
The alarm output is not incorporated with a short-circuit protection
circuit. Do not connect it directly to a power supply or a capacitive load.
Do not use the sensor at places having intense vibrations, as this can
cause malfunction.
Take care that the product does not come in direct contact with water, oil,
grease, organic solvents, such as, thinner etc., strong acid or alkaline.
Make sure that the sensing end is not covered with metal dust, scrap or
spatter. It will result in malfunction.
For stable sensing, carry out the adjustments 30 min., or more, after the
power supply is switched on.

٨This product is delivered after being adjusted with the standard sensing
object. However, since there are slight differences due to the sensing
object being used, carry out the adjustment as per the following
procedure, using a voltmeter or ammeter, oscilloscope, etc.
Ԙ
ԙ
Ԛ
Switch on the power supply after confirming that proper connection has
been made to the external device to which GP-A is to be connected.
Start the adjustment 30 min., or more, after switching on the power supply.
Open the cover on the top of the amplifier and set the 'button operation
effective / ineffective selection switch' to the 'FREE' side.
ԛTouching the sensor head to the sensing object, press the 'zero-
adjustment button' and set the zero-point. At this time, the analog
voltage output and the analog current output are forcibly set to 0V and
4mA, respectively.
ԜSet the sensor head at the maximum distance [GP-A5S(I): 1mm,
GP-A8S(I) and GP-A10M(I): 2mm, GP-A12ML(I): 5mm, GP-A14F(I):
3mm] from the sensing object. Now, adjust the analog voltage output
+5V or the analog current output to 20mA by turning the span adjuster
with the accessory adjusting screwdriver.
ADJUSTMENT

Note: Since the analog voltage output and the analog current output get adjusted simultaneously, it is
not possible to adjust them individually.
Make sure to carry out the adjustment 30 min., or more, after the power
supply is switched on.

Note: The analog current output is limited to a lower limit of 3mA and an upper limit of 23mA by a

Note: Since the span adjustment can be done irrespective of the 'button operation effective /

Notes: 1)
2)
The set values are not stored in the EEPROM if the power supply is switched off when the
switch is on the 'FREE' side.
If the switch is set to the 'LOCK' side before adjustment, the set values cannot be changed.
ԝ
Ԟ
Once again, touch the sensor head to the sensing object, and confirm that
the analog voltage output and the analog current output are 0V and 4mA,
respectively. In case they are not, repeat the adjustment from step ԛ.
The following shift adjustment and span adjustment can be done if
required.
ԟAfter the adjustment, make sure to set the 'button operation effective /
ineffective selection switch' to the 'LOCK' side.
࡮Using the 'shift-up button' and the 'shift-down button', it is possible to
adjust the offset value for the analog voltage output by r0.5V and that
for the analog current output by r1.6mA.
࡮As long as the sensing object is within the sensing range, the analog
voltage output and the analog current output can be adjusted to 0V and

Zero-adjustment can be remotely done by an external input by using the
zero-adjustment input terminals (terminal Nos. 5 and 6).
If the external zero-adjustment input terminals (terminal Nos. 5 and 6)
are short-circuited for 30ms, or more, the analog voltage output and the
analog current output are forcibly set to 0V and 4mA, respectively.
٨The external zero-adjustment input operation is independent of the state
of the 'button operation effective / ineffective selection switch'.
However, since the external zero-adjustment setting is not stored in the
EEPROM (memory), it is canceled when the power supply is switched off.
In case it is desired to store the setting in the EEPROM, set the button
operation effective / ineffective selection switch' once to the 'FREE' side
and again to the 'LOCK' side, before switching off the power supply.
EXTERNAL ZERO-ADJUSTMENT INPUT
6
Note: If the power supply is switched on with the external zero-adjustment input terminals (terminal
Nos. 5 and 6) short-circuited, since zero-adjustment gets done in the transient state of the power
supply switching on, stable sensing is not possible.
Further, ensure to apply the zero-adjustment input 30 min., or more, after the power supply is
switched on.
The external zero-adjustment input should be applied 30 min., or more,
after the power supply is switched on.
