•For PYX4
Slide the enclosed plastic panel mounting bracket (shipped with
every PYX4) up the back of the controller until it makes contact
with the back of the panel. Push the mounting bracket until the
tabs seat themselves in the molded tab ridges, located on the
front of the controller’s outer case. Tighten the two screw on the
mounting bracket for added pressure; do not use excessive
force.
•For PYX5/9
The mounting bracket’s tabs fit into the two holes on both the top
and bottom of the controller’s outer case. With an instrument
screwdriver, turn the screw in the mounting bracket until the end
of it touches the back of the panel. Do this to both brackets.
Making sure that the face of the controller is flush and straight,
tighten both mounting bracket screws. Your controller should
now be firmly set. If the controller is still loose, tighten the
mounting bracket screw a little more. Do not use excessive
force.

1.1Caution on wiring
1)For the safe operation of the controller, where the temperature probe is to
be installed into an environment where voltage exceed 50VDC, it is essential that reinforced isolation or basic isolation and earth the maintained between all connections to the rear of the temperature controller, and that
supplementary isolation is required for the alarm outputs.
in which there is a possibility of death or heavy
injury.
Wrong handling may cause a dangerous situation,
in which there is a possibility of injury or physical
damage.
The outputs from the controller are all less than 50VDC.
When wiring the power supply terminal, use vinyl insulated 600 volt cable
or equivalent. A switch breaking both poles of the mains supply should be
installed together with a fuse with a rating of 250 volt 1 Amp. The fuse
should be installed between the mains switch and the controller.
The level of insulation provided by the temperature controller is:-
MAIN = BASIC
HEATER = BASIC
INPUTS = BASIC
10
Prior to operation of the installed system the wiring should be checked to
ensure that the required levels of insulation have been provided.
2)When a fault in the instrument is likely to lead to a serious trouble, use a
suitable protective circuit on the outside for protection against trouble.
3)This unit is not provided with power switch, fuse, etc. These parts can be
installed separately, if required (fuse rating; 250V, 1A).
4)Use of Fuji's Z-Trap is recommended to protect the relay output from switching surge and to ensure a long life.

operation of the instrument. Some parts of the instrument are limited in life
or are subject to secular change.
WARNING
It is essential that, when the controller is introduced into a system
which uses or generates a hazardous voltage, the minimum creepage
and clearances specified in the table below are maintained on the
temperature probe. A hazardous voltage is one that exceeds 42.4V
peak AC or 60V DC. If you have any doubt, seek advice from a
competent engineer before installing the controller into the host
equipment.
The equipment must be installed such that with the exception of the
connection to the mains, creepage and clearance distances shown in
the table below are maintained between the temperature probe and
any other assemblies which use or generate a voltage shown in the
12
table below. Failure to maintain these minimum distances would

CAUTION
2.1Caution on handling
1)Do not install the unit in any of the following places.
•A place where the ambient temperature exceeds the range of -10
50°C
•A place where the ambient humidity exceeds 90%RH
•A place where temperature changes suddenly or dew condensation
occurs
•A place exposed to corrosive gases (sulfuric gas, ammonia, etc.) or
combustible gases
•A place where vibration or shock is likely to be directly transmitted to
the body.
•A place exposed to water, oil, chemicals, vapor, steam, etc.
•A place with much dust, salt or iron component
•A place with much inductive disturbance, static electricity, magnetism
or noise
〜
•A place exposed to direct sunlight
•A place where heat such as radiant heat stays
2)Mounting
•PYX5/9
For mounting, attach the supplied mounting brackets (2 units) on top
and bottom and tighten with a screwdriver. Tightening torque is about
147N.cm (1.5kg.cm). (The case is made of plastic. Care should be
taken not to tighten forcedly)
15
•PYX4
Insert the supplied mounting frame from the rear side and push it in
until the main unit is secured firmly to the panel. If it has a slight play,
tighten the 2 screws until the play is eliminated. (If the screws are tightened forcedly, the mounting frame may be slipped off the stopper)
3)When the unit is exposed to water, it may lead to a short-circuit or fire
hazard. Contact your dealer for inspection.
2.2Caution on cable connection
1)For thermocouple input, use a suitable compensating cable.
2)For resistance bulb input, use a cable with a small lead wire resistance and
without resistance difference between 3 wires.
3)When external wiring has much noise, use the following step. When a
conducted as load of digital output such as relay contact output or alarm
output, connect a surge absorber to the conductor coil. (Example:
ENC471D-05A for 200V AC)
4)When the power source has much noise, use an insulating transformer
together with a noise filter. Noise filter should be mounted on a panel which
has been earthed. The wiring between the noise filter output and the instrument power terminals should be as short as possible. Do not connect a
fuse or switch to the noise filter output wiring, as it affects the performance
of the filter.
5)Use of a twisted cable for the instrument power source provides better effects (short twist pitch is effective for noise).
6)When a heater burnout alarm is provided, the heater power and controller
power should be connected using the same power line.
7)Time for preparation of contact output is required at power ON. When the
output signal is used for an external interlock circuit, etc., connect a delay
relay to the circuit.
16
2.3Other
When cleaning the instrument, do not use organic solvents such as alcohol,
benzine, etc. Use neutral detergent.
3.Caution on key operation / trouble
(1)Alarm function should be set correctly. Otherwise, alarm output
cannot be obtained at the time of occurrence of trouble. Be sure to
check the function prior to operation.
(2)Do not stop the device forcedly during auto - tuning, as it affects the
control action. When it needs to stop forcedly, be sure to turn OFF
the power in advance.
(3)If the input cable is disconnected, the display shows UUUU or LLLL.
When replacing the sensor, be sure to turn OFF the power.

5.5NOTES
Connection:
• No power switch and fuse are provided on this product. Install
them separately if necessary.
• Use designated compensating wire in the case of thermocouple input.
• Use wire with line resistance lower that 10
thermoresistance input.
• To avoid noise induction to input wires separate from the
power and output wires also connected to your controller.
• In case of model equipped with heater break alarms, the
power supply used should be the same for the PYX and
Heater.
Ω
for
• Use shielded wires for input wires. Keep them away from
output wires.
Noise:
Take the following measures when there is serious noise
induction in the external wiring:
• When using a contactor as a load on digital output such as
relay contact output and alarm output, supplement a serge
absorber to the coil side of the contactor.
Z-Trap (ENB461D-14A for AC220V) manufactured by Fuji
Electric
• In the case of noise induction from the power supply, the use
of an insulated transformer and a noise filter is recommended.
Noise Filter (ZMB22R5-11) manufactured by TDK
• It is efficacious against noise induction to twist the power
wires.
28
Connection of Load Circuit:
• When the frequency of operation is rather high, in the case of
proportional operation for instance, maximum load with
respect to the capacity of the output relay will result in shorter
life. Use an auxiliary relay in such a case. Type SSR is
recommended.
electromagnetic switch: proportion cycle 20 sec. and above
SSR:proportion cycle 2 sec. and above
(approximately)
contact output life: mechanical: 10 million times (no load)
electrical:100 thousand times (nominal
load)
• Relay contacts will be worn out with time. After certain period
has passed, locking (a phenomenon in which a contact cannot
be released once switched on) may happen. It is advisable to
provide an external safety device to protect the system just in
case locking happens.

NOTES
1. Avoid applying the auto-tuning to the following processes.
(a)The process must not be disturbed due to temporary ON-OFF
control output from PYX.
(b)Process featuring very quick response such as pressure/flow
rate process.
(c)Process where overshoot must not be generated
2. Auto-tuning cannot be executed under the following conditions. If
the auto-tuning is already being executed, stop it.
(a)Manual operation
(b)Measured value (PV) error occurring
(c)When the set value (SV) has changed by more than 0.5%FS
per 0.5 second during auto-turning
(d)Auto-tuning not terminated within 12 hours
3. Do not execute auto-tuning when the ramp soak function is being
used (i.e. when the parameter “
” is not ), since it
may result in incorrect tuning.
4. When the operation condition is changed, restart the auto-tuning
5. When the auto-tuning terminates abnormally, the PID value takes
the value prior to auto-tuning, in such cases as abnormal
termination of auto-tuning. The same applies when the auto-tuning
command is switched to

3.FUZZY CONTROL
Employing Fuzzy Logic control eliminates system overshoot and
effectively suppresses fluction of the process variable due to external
disturbances. See the section describing control type setting (page75).
NOTES
1.The dual output type does not allow use of fuzzy control.
2.Though the fuzzy control also requires setting of parameters P, I,
and D, these values can be set to those being used in PID control.
Auto tuning is also available.

Perform transmission in accordance with the PYX Transmission
Protocol Specifications. In case of Fuji Electric CC data line protocol,
the available commands are for polling (parameter read), selecting
(parameter write) and control (parameter save). In case of Modbus
R
RTU (Radio Terminal Unit) protocol, they are for polling (parameter
read) and selecting (parameter write, including parameter save <fix>).
Communication settings are fixed as described below. Make sure that
the host side has the same settings.

NOTES:
1. For the control (parameter save) operation, a maximum of 5 sec is
required for the interval from receiving a command to completing the
operation.
Before ending of that interval, never turn the power
for this device off (otherwise, the memory contents are destroyed
and disabled).
2. This unit requires a time length of 100 to 120mS as the interval from
completing reception of a command from the host before returning
the response. It also requires 20mS before it is able to receive the
next command after completing a reply.

Remote SV function
This function is used to input a signal of 1 to 5 VDC externally, and
changes and controls the set value (SV) according to the input voltage.
This is useful for cascade control etc.
Operating procedure

the set value of the remote control. (The set value will be switched by bumpless).
3. The set value will be the low limit when the remote input is disrupted.
4. Fuzzy control can be used for set value (SV) changes in steps.
NOTES:

PID control
Fuzzy control
NOTES:
1. When control is made with the fuzzy, the PID parameter must be set
as with PID control. However, it need not be tuned particularly for
the fuzzy. (The values are allowed to be the same as those for PID
control.)
2. The fuzzy control mode also allows use of the autotuning function.
3. Fuzzy control cannot be used in the dual output type.
4. The two-set-point function is not available in the fuzzy control mode.
5. Fuzzy control can only be used when the set values change in
steps. Attention is required when the ramp soak function or remote
SV function is used.
