1. Outline
The J-APN 11 Multifunction Rulse-to-Pneumatic Pressure Converter responds to up (upward)and down
(downward)pulse signals. It drives pulses and a (four-phase) motor to send out pneumatic pressure
signals of 20 to 100[kPa] and current signals of 4 to 20 [mA] DC via a nozzle and a flapper mechanism.
In case of power failure, the converter automatically keeps the pneumatic pressure signal at its pre-failure
position (provided that the pneumatic source is in normal operation).

4-2. Adjustment of Pneumatic Pressure Output (Figure 4-2)
Perform zero and span adjustments of pneumatic output with mechanical stoppers for upper and lower
limits (between the 56T helical gear and base) in contact.
Use the fine-zero adjustment screw and fine-span adjustment nuts on the transmitter.
1) At the lower contact with mechanical stopper
Pneumatic pressure output: 16kPa (-5%F.S.) ±1%F.S.
2) At the upper limit of contact with mechanical stopper
Pneumatic pressure output: 104kPa (105%F.S.) ±1%F.S.
Repeat zero and span adjustments until conditions (1) and (2) are met.
• Turn off power and remove the pulse motor connector, so that coupling can be done easily by hand.
• Pneumatic pressure output is measured by connecting a tube to the pneumatic pressure output check
plug.
Note 1 : Upper and lower limits are set to -3+/-1%F.S. and 103+/-1%F.S. The output value
must not exceed the mechanical stopper range.

4-3. Adjustment of Current Output (Figure 4-3)
4-3-1. For direct feature
Conduct wiring and piping as shown in Figure 3-2-1.
1) Adjust input up and down so that pneumatic pressure output is about (*1) 20kPa (0% F.S.), then zeroadjust the P/I converter to attain current output corresponding to pneumatic pressure output (*2).
2) Adjust input up and down so that pneumatic pressure output is about 100kPa (100% F.S.), then spanadjust the P/I converter to attain current output corresponding to pneumatic pressure output.
Repeat steps (1) and (2) until the specified accuracy is achieved.
For reverse characteristics, start from step (3) below.
(*1): Pneumatic pressure output cannot be set precisely since it changes with a pulse motor.
(*2): To calculate the current output corresponding to pneumatic pressure output:
I = 4 + ( ) 16
P – 20
80
I : corresponding current output [mA DC]
P: pneumatic pressure output [kPa]
4-3-2.
For reverse feature
1) Set pneumatic pressure output to about 20kPa (0% F.S.). Zero-adjust so that current output becomes
20mA.
2) Set pneumatic pressure output to about 100kPa (100% F.S.). Span-adjust so that current output
becomes 4mA. (See (2) note (*2) of Section 4-3-1.)
Repeat steps (1) and (2) until the specified accuracy is achieved.

1) For models with both a pneumatic-pressure signal monitor (set at M1 (upper limit): 90±1%F.S., M2
(lower limit): 10±1%F.S.when shipping) and a supplied-air pressure drop monitor (set at 110kPa
when shipping), alarm settings are changed by adjusting the setting wheel on each unit. To raise the
set value, turn the setting wheel counterclockwise.
When only one monitor is used, select the upper limit or lower limit alarm.
2) Connect the monitor unit terminal and customer terminal connection cable as shown below.

4-6. Manual Operation (with A/M switch)
A manually-operated unit has a reducing valve for manual pneumatic-pressure setting and auto/manual
switch.
From this unit, switch A → M and M → A following the procedure below.
Under automatic operation (lever set to A), the automatic adjustment output pneumatic pressure is
displayed on the output pneumatic-pressure manometer. Pressing the check button displays output
(manual adjustment output pressure) of the reducing valve. To switch to manual operation, operate the
setting knob of the reducing valve to set the manual output to be the same as the automatic output, then
switch the mode.
Under manual operation (lever set to M), the reducing valve output is displayed on the output pneumaticpressure manometer, and remote operation of the valve is enabled. Pressing the check button displays
automatic adjustment output. To switch to automatic operation, set automatic output to the same as
manual output, then switch the mode.

6. Maintenance
6-1. Reguler Maintenance
1) Check the supplied air pressure
Keep the supplied air pressure unit clean. Drain unit and check filters regularly. Check the
compressor, the air cleaning and dehumidifying unit, and the tank.
6-2. Periodical Maintenance and Checking
1) Check for air leaks
Make sure that there is no air leak from the air pipe or the connection joints.
2) Check the nozzle flapper for staining
Remove stains on the nozzle flapper of the pneumatic pressure sending unit (mechanical parts
assembly, see Figure 4-2, with a cloth impregnated with a solvent such as petroleum, naphtha
or chlorosene 1, 1, 1-Trichloroethane (Chloroethene). Wipe gently to prevent damage to the
flapper beam (plate spring).
3) Check the gear mechanism of the pulse motor for wear
Damaged or worn gears, especially the worm gears and worm wheels must be replaced.
4) Check the pilot relay (Figure 6-1)
(1) Remove the pilot relay from the manifold : remove the two screws (14), the spring
washers (15), and the gaskets.
(2) Disassemble the pilot relay : remove the two flat-head screws (13).
(3) Dismount parts (6) to (12). Parts (2) to (5) need not be dismounted unless they need
replacing.
(4) Clean the metal parts with a solvent such as petroleum, naphtha or chlorosene. 1, 1, 1-
Trichloroethane (Chloroethene).
Do not stain the diaphragms with the solvent.
Clean the valve stem (2) on the seal surface and the hole. Let solvent be absorbed by
pressing the conic spring (4) to push the valve stem (2) in the compression direction.
(5) Check the inside of the exhaust ring (10) for stains. If stained, clean with a cloth
impregnated with a solvent.
(6) Dry all the parts with clean compressed air.
(7) Replace the rubber diaphragms (8) and (11) if they are worn or damaged.
(8) Reassemble the pilot relay : replace all parts in correct order and tighten them with two
flat-head screws (13).
(9) Remount the pilot relay on the manifold, position the gasket (1) correctly.
(10) Fix the pilot relay on the manifold using mounting screws (14) and two spring washers
(15).
6 - 1
5) You are recommended to replace rubber parts (such as the diaphragms and gaskets on the pilot
relay, the tube for piping, and the O-ring for the check plug of the pneumatic pressure sending
unit) at intervals of about five years, though this may vary depending on conditions.
