(1) Attach to the position that the valve stem and lever form the right angle
when the input signal is 50% (distribute evenly with 50% input signal set as
the reference).
(2) Attach to the position of the runout angle is within the range of 10° to 30°.
(3) To move the valve stem downward at the time of input current increase
(normal actuation), attach to the position at which the tightening spring
comes to the upper side of the connecting metal, as shown in Fig 5.
To move the valve stem upward (reverse actuation), turn-over the feedback
lever and attach to the position at which the tightening spring comes to the
lower side of connecting metal.
4.2 Type IP8100
4.2.1 Example of attaching to actuator
The type IP8000 positioner is compatible with type IP610 and IP6100 in
the attaching pitch. If you are using IP610 or IP6100 already, the bracket
can be used to attach IP8000 to the actuator. If you change from IP6100
to IP8100 and select accessory H (with external scale plate), fork lever
type fitting needs to be adjusted at lower position.

CAUTION
Check the following prior to start the adjustment.
(1) Check that the pipeline is correctly connected with the pressure supply
port and OUT1 and OUT2 ports.
(2) Check that the actuator and positioner are sturdily connected.
(3) Check that the span adjusting lever of internal feed back (Type IP8000)
is attached to the correct (normal or reverse)
(Refer to Tables 2.)
(4) Check for locking of the auto/manual changeover screw of pilot valve
(fully tightened in the clockwise direction).
5 Adjustment (continued)
(5) Check for correct use of the cam face (normal or reverse) in Type
IP8100 and that the flange nut is firmly locked. (Refer to Table 2.)
(6) Check that the wires are connected correctly with the (+), (-) and
grounding terminals.

6 Maintenance
Input current
(1) After installation, repair and disassembly, connect compressed air
Span adjusting
screw and perform a proper function test and leak test. If bleed noise is
louder than the initial state, or operation is abnormal, stop operation
*²
and check if installation is correct or not.
(2) Modification of Electrical construction is prohibited to maintain
explosion proof certification.
Move clockwise
(1) Check if supply air is clean or not. Inspect compressed air cleaning
system periodically so that dust, oil and humidity, which can cause
malfunction and failure of the unit, do not enter the equipment
(2) If handled improperly, compressed air can be dangerous.
Maintenance and replacement of unit parts should only be
performed by trained and experienced personnel for instrumentation
equipment , as well as following the product specifications.
(3) Check the positioner once a year. When an excessively worn
diaphragm, O-ring or other packing of any unit that has been
damaged is found, replace with new ones. Treatment at an early
stage is especially important if the positioner is used in a place of
severe environment, such as costal areas.
(4) Before removing the positioner for maintenance, or replacing unit
parts after installation, ensure the supply pressure is shut off and all
residual air pressure is released from the piping.
(5) When the fixed orifice is clogged with carbon particles or other
material, remove the pilot valve Auto/Manual change over screw
(built in fixed aperture) and clean it by inserting a 0.3mm diameter
wire into the aperture.
(6) When you disassemble the pilot valve, coat the O-ring of the sliding
section with grease. (Use the Dow Corning Toray Company, Limited
SH45 grease.)
(7) Check for air leaks from the compressed air piping. Air leaks could
lower the performance characteristics of the positioner. Air is
normally discharged form a bleed port, but this is necessary air
consumption based on the construction of the positioner, and is not
an abnormality if the air consumption is within the specified range.
(8) If atmosphere is below freezing point, take measure to avoid
freezing the supply pressure and the actuator.
