  • Page 3: Safety Instructions P2

    E-P Regulator Manifold type Safety Instructions These safety instructions are intended to prevent hazardous situations and/or equipment damage. These instructions indicate the level of potential hazard with the labels of “Caution,” “Warning” or “Danger.” They are all important notes for safety and must be followed in addition to International Standards (ISO/IEC) , and other safety regulations.
  • Page 4 E-P Regulator Manifold type Safety Instructions Caution The product is provided for use in manufacturing industries. The product herein described is basically provided for peaceful use in manufacturing industries. If considering using the product in other industries, consult SMC beforehand and exchange specifications or a contract if necessary.

  • Page 5: Handling Precautions P4

    Handling precautions △ Caution ！ If the power supply to this product is turned off due to a power failure during normal operation, the output on the secondary side will be held and air will flow continuously. If supply pressure to this product is interrupted or shut off, while the power is still on, the internal solenoid valve will continue to operate, and a humming noise will be generated.

  • Page 6: Internal Communication Specifications P5

    Internal communication specification ■Process data Process data is cyclic data exchanged periodically by [E-P regulator - PLC]. Process data consists of PD_IN (process data input): 4 byte and PD_OUT (process data output): 2 bytes. The process data of this product is Big-Endian type. When the transmission method of the upper communication is Little-Endian type, the byte order will be changed.
  • Page 7 Diagnostic information This product can detect the device error by diagnostic bit in the process data. byte value Abnormal Warning Notification Disabled SSC1 bit offset Item Note 1: Output pressure value is within +/-10% of the target value. SSC1 0: Other than the above case. Disabled 0: Vacant.
  • Page 8 Process data output: 2byte [PLC - E-P Regulator] The product adjusts the pressure to the set value. byte Set pressure value (16-bit) value * Data is adjustable up to 120%F.S. (However, the warranty range is up to 100% F.S.) Pressure setting mode. The pressure can be set by sending input data with a full span of 12-bit from the PLC to the electro-pneumatic regulator.

  • Page 9: Setting Parameters Via Communication P8

    Setting parameters via communication The output at the time of communication error, gain adjustment, sensitivity adjustment, minimum pressure, maximum pressure, and notification of accumulated time can also be set via communication. Do not configure settings using the button operation and communication at the same time. If settings are made by both methods, unintended settings may be configured.
  • Page 10 Parameter name Gain setting The response time can be changed by tuning the gain. If the over-shoot is large, decreasing the gain tends to improve it, but the responsiveness becomes slower. Conversely, when the gain is increased, the response time tends to be faster, but stability will be lost, which may cause hunting (unstable Function pressure).
  • Page 11 Parameter name Sensitivity setting Adjusting the sensitivity changes the pressure correction operation near the set pressure point. When the load capacity on the secondary side is large and hunting (unstable pressure) occurs, decreasing the sensitivity tends to improve the hunting. However, as the pressure correction is reduced, Function moderate pressure instability may occur.
  • Page 12 Parameter name Setting of Min. pressure, Max. pressure It is possible to change the minimum pressure (hereinafter referred to as "F_1") and the maximum pressure (hereinafter referred to as "F_2"). In normal use, use the product in the condition when shipped, it is not always necessary to adjust the setting of minimum pressure, and the setting of maximum pressure.
  • Page 13 Parameter name Notification setting of the accumulated energizing time This function uses process data to notify the user that the accumulated energizing time of the electro-pneumatic regulator reached the time set with this function. The default value is "0," which means no notification is output. Function If the value is "1"...
  • Page 14 Setting using buttons  Caution (1) If the incorrect key is pressed or incorrect information is displayed during setting, power must be shut off and the procedure started again. (2) It is recommended that the settings are changed without supply pressure. The product operates immediately maximum and minimum pressures are set and the SET- key is pressed.

  • Page 15: Key Locking Function P14

    Key locking function  Caution The key lock function is preserved in the EEPROM (non-volatile memory). Its settings are reflected even after power cycling (The key lock is deactivated by default at shipment). However, when buttons are operated, the button operations take priority and the settings via communication are processed exclusively.

  • Page 16: Setting Of Min. Pressure, Max. Pressure P15

    Setting of Min. pressure, Max. pressure These interlock with the communication parameters. It is possible to change the minimum pressure (hereinafter referred to as "F_1") and the maximum pressure (hereinafter referred to as "F_2"). In normal use, use the product in the condition when shipped, it is not always necessary to adjust the setting of minimum pressure, and the setting of maximum pressure.

  • Page 18: Gain Setting P17

    Gain setting This setting can also be configured using the communication. The response time can be changed by tuning the gain. If the over-shoot is large, decreasing the gain tends to improve it, but the responsiveness becomes slower. Conversely, when the gain is increased, the response time tends to be faster, but stability will be lost, which may cause hunting (unstable pressure).

  • Page 19: Sensitivity Setting P18

    Sensitivity setting This setting can also be configured using the communication. Adjusting the sensitivity changes the pressure correction operation near the set pressure point. When the load capacity on the secondary side is large and hunting (unstable pressure) occurs, decreasing the sensitivity tends to improve the hunting. However, as the pressure correction is reduced, moderate pressure instability may occur.

  • Page 20: Zero Clear P19

    Zero clear The display can be set to zero again by executing "zero clear". When "zero clear" is executed with residual pressure in the secondary piping, the pressure is assumed to be zero. Please execute the operation of "zero clear" with the supply pressure is intercepted, and the piping of the second side removed.

  • Page 21: Reset Function P20

    Initialize "Initialize" is a function to return all the settings that the internal control constant is included to an initial value. Please execute "initialize" only when the error is displayed, and this product doesn't operate at all. Please execute the "reset" function, when you want to return the pressure setting and the switch setting to an initial value.

  • Page 22: Error Indicating Function P21

    Error indicating function Error Contents of error Countermeasure name display Over range Reduce input signal to within the Input signal exceeds the rated range and restart the power rated value range. input signal supply. Please execute "initialize (refer to P20)" when ITV do not operate normally after restarting the Reading or writing errors power supply.
  • Page 23 Maintenance ■ Before performing maintenance, turn off the power supply, stop the air supply, exhaust the residual compressed air in the piping, and verify the release of air to atmosphere. ■ Foreign matter caught in the inlet of piping or exhaust may interfere with normal operation. Periodically conduct cleaning.
