CAUTION ON SAFETY

First of all, read this “Caution on Safety” carefully, and then use the instrument in the correct way.

The cautionary descriptions listed here contain important information about safety, so they should always be observed. Those safety precautions are classified in 2 ranks, WARNING and CAUTION.

The following shows the meaning of WARNING and CAUTION.

Wrong handling may cause a dangerous situation, in which there is a possibility of death or

WARNING

1. WARNING

heavy injury.

Wrong handling may cause a dangerous situation, in which there is a possibility of injury or physical damage.

1.1 Caution on wiring

(1) For the safe operation of the controller, where the temperature probe is to be installed into an environment where

voltage exceed 50V DC, it is essential that reinforced isolation or basic isolation and earth is maintained between all connections to the rear of the temperature controller, and that supplementary isolation is required for the alarm outputs. The outputs from the controller are all less than 50V DC. 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:-

MAINS = BASIC HEATER = BASIC INPUTS = –––

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.

Type: ENC241D - 05A (power voltage; 100V)

ENC471D - 05A (power voltage; 200V)

Mounting position: Connected to relay control output terminals

ii INP-TN3PYH-E

CAUTION ON SAFETY

1.2 Power source

(1) Use a power source of rated voltage to prevent damage or trouble. (2) Do not turn ON the power until the wiring is completed to prevent shock hazard or trouble.

1.3 Prohibition of use in gas

The instrument is not an intrinsic safety explosion-proof type. Do not use it in a place exposed to combustible or explosive gas.

1.4 Contact to unit

(1) This unit must not be disassembled, modified or repaired to prevent malfunction, shock hazard or fire accident. (2) When the power is ON, do not touch the terminals to prevent shock hazard or malfunction.

1.5 Caution on maintenance

(1) Before mounting or removing the module or unit, turn OFF the power in advance to prevent shock hazard, mal-

function or trouble.

(2) Periodical maintenance is recommended to ensure continuous and safe operation of the instrument. Some parts of

the instrument are limited in life or are subject to secular change.

2. CAUTION

2.1 Caution 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 to 50°C

•A place where the ambient humidity exceeds the range of 45 to 85%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

For mounting, attach the supplied mounting brackets (2 units) on top and bottom and tighten with a screwdriver. Tightening torque is about 147N·cm. (The case is made of plastic. Care should be taken not to tighten forcedly.)

(3) When the unit is exposed to water, it may lead to a short-circuit or fire hazard. Contact your dealer for inspection.

2.2 Caution 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)

INP-TN3PYH-E iii

CAUTION ON SAFETY

(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.

2.3 Other

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.

4. PREPARATION FOR OPERATION, AND OPERATION

4.1 Preparation for operation

To ensure correct operation of the controller, it is necessary to set parameters before operating, according to the procedures shown in (3) Setting method of main alarm set values (AL1, AL2) of item "4.2 Operation". While setting parameters, be sure to stop the operation of the external system for the sake of safety.

Kinds of parameters Refer to "15. Parameter list" on page 35. Note that some parameters in "15. Parameter list" are not used depending

on the type of PYH, which are not displayed by the indicator on the front of PYH.

4.2 Operation

(1) When power turns ON, measured value (PV) and set value (SV) are indicated a few seconds later to start operating.

The indication of measured value and set value is called the operation indication. Heat up time of PYH is two hours. Measuring and controlling of PYH should be operated after the heat up time.

The setting method for AL2 is the same as above. Indicate AL2 referring to “15. parameter list” on page 35 and follow the above procedures.

Auto-tuning is a function to set up the parameter of PID automatically with PYH for operation. a) Auto-tuning should be performed after setting the set value (SV), main alarm 1 & 2, and proportional cycle

(C1, C2 *1). *1: With control output 2 produced

(Note) Auto-tuning may require several 10 minutes depending on process response characteristic.

Note 1) During auto-tuning, vibration of process is observed. It is a phenomenon of auto-tuning, which is

stabilized at the completion of auto-tuning. Note 2) When operating conditions are changed, carry out auto-tuning once again. Note 3) Do not use auto-tuning for the following processes.

• Process disorder due to temporary ON-OFF control output from PYH is prohibited.

• Pressure or flow process having very quick response.
