Note 2

Control output 2 (the codes “ A, C, and E ” in the 7th digit) cannot be specified.

Note 3

Control output 2, communication digital input (2 points), alarm (2 points), and 24V power supply (the codes “ A, C and E ” in the 7th digit, “ F and G ” in the 9th digit, and “ A, B, and C ” in the 10th digit) cannot be specified.

The default settings of input signals, measured ranges, and setting values are shown below.

Thermocouple specified : Thermocouple K, Measured range: 0 to 400°C,

Resistance bulb specified : Pt, Measured range: 0 to 150°C, Setting value:

Operations

This chapter explains how to set the SV (Setting value) and the parameters for the PXR.

2-1 Parameter list

Parameters for the PXR are classified under three blocks according to the frequency of use. The parameters of the second and third blocks are used at initialization or when they are of absolute necessity. Some parameters may not be displayed at the time of delivery depending on the type of the instrument.

• During standby, the control output and the alarm output stay OFF, like the standby for ramp-soak operation. Retransmission output is kept operated. (However, if the type of retransmission output is set to the MV, it becomes 4mA or lower.)

• While the alarm with a hold is selected, the hold function takes effect after changing the Standby setting from ON to OFF.

• is displayed during the standby for ramp-soak operations or the controller changes to the standby state in case of the occurrence of errors.

• The other operations are the same as those of the rampsoak standby.

•The setting of ON/OFF for standby is saved after po wer off.

•When the standby is set to ON during the auto-tuning, self-tuning, and ramp-soak operations, those operations will stop. (The PID constant will not be renewed.) Even through it is set to OFF later, the auto-tuning, self-tuning, and ramp-soak operations will not be re-started.

• During standby, the ON-delay timer is reset. When returning to RUN from the standby state, the timer will start from the beginning.

•The SV lamp flickers only when standby state.

Cycle time of control output 1 (Setting range: 1 to 150 seconds)

• While input is within the proportional band, output changes between ON and OFF in cycles. These cycles are called cycle time.

Output: ON

• Do not set this parameter to "0".

For contact output:

The higher the frequency of output is, the more precise the control becomes. However a high frequency of output may shorten the life of the contacts and the device to be controlled. Be sure to adjust the proportional cycles considering controllability and the life of the device and the contacts.

Typical: 30 seconds

For SSR-driving output:

Use in short cycles if there is no problem with the device to be controlled.

Typical: 1 to 2 seconds

• Input signals can be selected within the same type. It is impossible to select input signals of a different type.

• For type II, when changing from the voltage input to the current input, connect the supplied resistance of 250 Ω between terminals w and e . When changing from the current input to the voltage input, remove the resistance of 250 Ω connected to the input terminals.

2. Output at END: The output status at the END of the ramp-soak operation.

3. Output at OFF: The output status while the ramp-soak operation is set to OFF.

Repeat operation:

This function makes the ramp-soak operation to continue after one cycle of ramp-soak operation is completed. At the e vent of Repeat operation: OFF, the SV that is set in the final cycle is kept.

* Standby mode: Output: control output OFF or -3%

[Soak]

The segment in which the set value is always the tar get value and remains unchanged.

•Even if the ramp time and the soak time of a segment are set to zero, the SV of the segment is used as the starting value of the next segment.

Specifying control system and action, and output direction at input burn-out (Setting range: 0 to 19)

[Description]

• This parameter specifies action (Single/Dual and Heating/ Cooling), and output direction at input burn-out.

• The standard model (single output) or the heating/cooling control output (dual output) are available.

•There is defference of hardware between the standard model and the heating/cooling control output model. Set the code that is applicable to your controller.

• In general, reverse action is applyed for the heating process and direct action is applyed for the cooling process.

*The lower limit of a burn-out output indicates

that output is set to OFF, or 4mA or less. The upper limit indicates that output is set to ON, or 20mA or more.

* Retransmission output is kept operated. How-

ever, if the type of retransmission output is set to the MV, the output becomes the same as the output at burnout.

range (Note 1)

MV Output value

•When the value of retransmission output (example: SV) becomes equal to the set value of Ao-L, the retransmission output becomes 0% (output).

•When the value of retransmission output (example: PV) becomes equal to the set value of Ao-H, the retransmission output becomes 100% (output).

Note 1: Calculate the set value by using the following for-

mula (refer also to the setting example shown below).

Set value (%) = (A ÷ B) × 100 [%]

A = Temperature to be set – Set value of parameter "P-SL" B = Set value of parameter "P-SU" – Set value of "P-SL"

•Be sure to always set smaller than .

[Setting example]At K thermocouple input of 0 to 400˚C, mak e the setting so that the PV (v alue

of retransmission output type) becomes 0% at 100˚C, and 100% at 300˚C.

Since the measurement range is 0 to 400˚C, P – SL = 0 (lower limit v alue of measurement range), and P – SU = 400 (upper limit value of measurement range). So, from the formula shown above, A = (100˚C – 0) or (300˚C – 0), B = 400 – 0 = 400

1) Setting Ao-L : What position is 100˚C in the temperature range from 0 to 400˚C ? = 25% (=(100

2) Setting Ao-H: What position is 300˚C in the temperature range from 0 to 400˚C ? = 75% (=(300 – 0) ÷ 400 × 100 [%]) → Ao-H = 75.0 (%)

Memo

Safety Precaution

● Before using the PXR3, read the “Instruction Manual” or consult with your local distributor or Fuji Electric for safety

purpose.

● The uses and places for some of equipment described in this manual are limited. Some devices need regular inspec-

tions. Consult with your local distributor or Fuji Electric.

● Only electricians should connect this equipment.

● The contents of this manual have been prepared carefully. However, it should be noted that Fuji Electric is not respon-

sible for any loss, including consequential damage from errors in writing or missing information. Before operating the PXR3, carefully read the safety precaution in the “Instruction Manual”.

Over-temperature Protection

Any control system design should take into account that any part of the system has the potential to fail.

For temperature control systems, continued heating should be considered the most dangerous condition, and the machine should be designed to automatically stop heating if unregulated due to the failure of the control unit or for any other reason.

The following are the most likely causes of unwanted continued heating:

1) Controller failure with heating output constantly on

2) Disengagement of the temperature sensor from the system

3) A short circuit in the thermocouple wiring

4) A valve or switch contact point outside the system is locked to keep the heat switched on.

In any application where physical injury or destruction of equipment might occur, we recommend the installation of independent safety equipment, with a separate temperature sensor, to disable the heating circuit in case of overheating.

The controller alarm signal is not designed to function as a protective measure in case of controller failure.
