Operating Principle
When the input current (4 to 20mADC) increases, the current which is applied to the coil of the
torque motor (12) through the input, operation and output processing circuits (8) changes, causing
the armature (13) to start rotating with the fulcrum of the leaf spring (11). Along with this, a gap is
created between nozzle (6) and flapper (5), and nozzle back pressure decreases.
As a result, the exhaust valve (7) inside of pilot valve (1) moves to the right, pressure at OUT1
increases and pressure at OUT 2 decreases, causing actuator (14) to move. The motion of actuator
(14) is transmitted through the fork lever-type fitting, feedback shaft (10) and angle sensor (9). The
displacement processing output circuit (8) then matches the input current to the corresponding
output position.
Fig. 3
How to Operation
IP8101 positioner can be operated by two methods, by the operation button (mode, up, down)
installed in the positioner and HART communication (option). Refer to this operation manual for the
operation with operation button and refer to “HART communication function”in the operation
manual separately for the HART communication.

Mounting
1. Confirm the positioner is securely and firmly mounted onto the actuator.
2. Be careful not to get a finger caught when matching mounting positions.
1. Be sure to keep the necessary space available for maintenance work (piping, wiring,
adjustment, etc.) in your setup location.
2. Cut off the pressure supply to ensure compressed air is discharged from the positioner
and actuator completely before starting mounting.
3. When removing the positioner from the actuator and mounting it onto another actuator,
malfunctions may occur due to its remained initial constant. Therefore, when it is mounted
onto other actuators, transmit the input signal while cutting the air supply, and be sure to
perform Simple balance current adjustment through the calibration mode (parameter
code: C20). Then apply the air while biAS is indicated on the LCD and perform the Simple
balance adjustment (parameter code: C20) and calibration (parameter code: C30).
■Example of Mounting on Actuator
IP610, IP6100 and IP8100 offer interchangeability in mounting pitch with IP8101 smart positioner.
Therefore, it is possible to apply a bracket for IP610, IP6100 and IP8100 for mounting＊1. However, if
IP6100 is replaced with this positioner and accessory H (with an external scale plate) is selected, it
is necessary to lower the position of the fork lever-type fitting.
1: IP610 and IP6100 have the same mounting pitch as IP8101, but a different mounting height. Watch for
interference between the bracket mounting screw and bottom face of the positioner body.
Warning
!
Caution
!
Mount using the hole on the side face of
the positioner and on the top of the
actuator.
Mount by using the holes on the back of
the positioner and the top of the actuator.

■Connection with Feedback Shaft
(1) Screw in a fork lever-type fitting to the major
shaft of actuator and adjust its height to avoid
interference with the fork pin unit.
(2) Adjust the angle of the fork lever-type fitting
to avoid interference with the positioner body
while the actuator is fully opening from a
fully-closed condition＊2.
(3) Mount so that the feedback shaft of the
positioner and major shaft of actuator are
almost aligned (where the spring pin at the
end of the feedback shaft engages with a
hole at the end of the fork lever-type fitting
axis).
2: Fig. 7 shows the details of how to adjust the fork
lever angle. Adjust the fork lever angle to avoid
interference with the positioner foot when the
positioner fork pin unit rotates along with the
actuator. Also, the effective angle of the
positioner angle sensor is +/-60o, and the fork
lever-type fitting has to be fixed to remain within
that range. The angle can be checked by
following the instructions in “2. Adjustment of fork
lever-type fitting angle”of “■Initial Adjustment”.
3: Pay attention not to apply a strong impact to a feed back shaft of the positioner when the shaft is
connected to a fork lever-type fitting. The angle sensor might be damaged due to the strong impact. Do
not apply any impact when the positioner and actuator are connected.

■Fork Lever-Type Fitting
Since the IP8101 has two means of being mounted, two different kinds of fork lever-type fittings are
provided, which are mounted in different ways, depending on the bracket mounting method.
For side mounting, the mounting dimensions of fork lever-type fitting M can be adjusted to be
interchangeable with IP610. For back mounting, the mounting dimensions of fork lever-type fitting S
can be adjusted to be interchangeable with IP610.
■Body cover
2 types of body cover unit can be selected. These can be ordered for replacement.
Cover with window to check LCD is optional.

Piping
Do not touch near the actuator axis when supplying air after piping.
1. Perform sufficient pipe flushing and remove cutting chips, oil and dust from the piping to
prevent foreign matter from entering the positioner.
2. When connecting an SMC fitting to an air connection port (SUP, OUT1, OUT2), apply a
tightening torque of 12 to 14Nm. The tightening torque must be suitable for the tube fitting
in use.
■Double Acting Actuator
Perform piping on the positioner and actuator in the following manner. Also, when piping in cases
where the actuator rotates clockwise with the appropriate parameter setting (dir)
(direct operation)＊1. For the piping layout, refer to “Double acting”in Table 6.
(1) Connect the pressure supply piping to the positioner SUP port.
(2) Connect the OUT1 port of the positioner to the air port of the double acting actuator (which
rotates clockwise as pressure increases) and the OUT2 port of the positioner to the air port of
the double acting actuator (which rotates counterclockwise as pressure increases).
■Single Acting Actuator
Perform piping of the positioner and actuator in the following manner. Also, when piping in cases
where the actuator axis is located at the end of counterclockwise rotation with a spring force and the
actuator rotates clockwise with appropriate parameter setting (dir) (direct operation)＊1. For the
piping layout, refer to “Single acting”in Table 6.
(1) Connect the pressure supply piping to the positioner SUP port.
(2) Connect the positioner OUT1 port to single acting actuator air port.
(3) Plug the OUT2 port.
1: The positioner operating direction can be changed by the parameter settings (parameter code: 200). For
parameter details, refer to “■Parameter Code Details”. At such times, changing the piping is unnecessary.
The settings described in this section decide the operating direction via the appropriate parameter
settings (dir).

2: Calculate the maximum load resistance compatible with analog output from the specifications table (Table
2) and following equation (Common for both non-explosion protected specification and intrinsic safety
type of explosion protected construction specification).
<Ex.: Analog output>
Power supply voltage of 24V DC,
Load resistance ＝(24V DC－10V DC) / 24mA DC = 583Ω(Up to 0 to 583Ω)
3: Alarm output for non-explosion protected specification requires 10mADC or more to operate the main
circuit of the internal switch, and it should be 40mADC or less to protect the internal resistance circuit.
Therefore, use a power supply voltage and load resistance with a load current of 10 to 40mADC when the
output is on.
<Ex.: Alarm output 1>
Power supply voltage 24V DC and load resistance 1kΩ(+ internal resistance 350Ω),
Load current = 24V DC / (1kΩ+ 350Ω) = Approx. 18mA DC
4: Determination of load resistance of alarm output for intrinsic safety type of explosion protected
construction specification.
<Ex.: Alarm output 1>
Power supply voltage 24V DC,
Load current = 24V DC –5V DC / 3.15mA DC = 6080Ω(Up to 0 to 6.08kΩ)

4. This positioner becomes ATEX intrinsic safety type of explosion protected construction when
its part number is selected as 52-IP8101-034--. The basic type (IP8101-030-*), output
function type (IP8101-032), and HART communication type (IP8101-033) must not be used
in a place with an explosion risk.
5. Positioner has an aluminium alloy enclosure. When used in a potentially explosive atmosphere
requiring the use of category 1G equipment, the apparatus must be installed so that, in the
event of rare incidents, an ignition source due to impact or friction is excluded.
6. Do not use it in a non-hazardous area where air leakage would cause a risk.
7. If a positioner is used in a hazardous area, speed of the actuating part should be 1m/s or less.
The actuator should not have hunting.
8. Make sure to use a grounding terminal, and grounding should be performed based on an
electric work policy in each region.
9. The temperature at a positioner surface should not be increased more than the temperature
rate by direct sunshine.
10. To maintain explosion protected construction, the electric circuit should not be changed.
11. Safety Barriers used in the positioner supply circuit must be linear resistive output type
barriers, in accordance with the I.S. Parameters given in the specifications (see Table 1).
12. Explosion protected cable gland supplied for M20X1.5 electrical connections (for
52-IP8101-034-*-M) is approved to ATEX II 2GD, but subsequently tested by the notified
body in accordance withATEX II 1GD during certification of the 52-IP8101 positioner.
■ATEX Intrinsic Safety type of Explosion Protected Construction
IP8101 type smart positioner has an explosion protected construction which was approved by
DEKRA, a notified body for explosion protected certification, as ATEX compliant intrinsic safety
type of explosion protected construction. Please pay full attention when it is used as an explosion
protected construction specification.
■Explosion Protected Construction Rate
The 52-IP8101 model is compliant with the ATEX Directive 2014/34/EU, Intrinsically Safe type of
Construction, toⅡ1G Ex iaⅡC T4-T6 Ga classification, T4/T5 -20℃≦Ta≦80℃T6 -20℃≦Ta≦
60℃according to EN 60079-0:2012+A11:2013,EN 60079-11:2012 AND EN ISO 80079-36:2016.
■Wiring
If 52-IP8101 type smart positioner is used as a intrinsic safety type of explosion protected construction, a
barrier must be set at non-hazardous area like Fig. 12, and each positioner must have wiring via the
barrier. For wiring the positioner 52-IP8101-034-*-M/2/5, the attached cable gland (M20x1.5) should be
used for the electrical entry (see Fig. 13). Except for the positioners 52-IP8101-034-*-M/2/5, a cable
gland that has the same explosion protected construction rate or better as those positioners.
