  • Page 5 1. Outline IP8*00 Series electro-pneumatic positioner controls the motion of actuator by the operation of pilot valve. This pilot valve is activated by signal current from adjustment unit mounted to air cylinder. Specials of “-X14” received the certification of “Intrinsically safe explosion proof conforming with ATEX directive (Ex ib CT5/T6 Gb ) ”...

  • Page 15: Electrical Wiring

    Caution Prior to piping, flush enough and remove chip, cutting oil and dust in tube so that obstruction wouldn’t intrude into positioner. Confirm specification and working direction of actuator, and mount pipes and internal feedback unit in accordance with table 2 and 3. 6.
  • Page 16 Warning 1. A positioner must be energized only after wiring via a barrier. 2. Use a linear resistance type barrier based on intrinsically safe parameter for the input circuit. 3. If a positioner is used as intrinsic safety type of explosion protected construction for ATEX, connect it only to the intrinsically safety electric circuit with the following maximum value.
  • Page 17 7. Adjustment Caution (1) For this positioner, span and zero point adjustment of each actuator is necessary. Adjustment shall be done based on each actuator size. (2) Keep in mind that span and zero point adjustment interfere in each other. (3) Characteristics changes due to change of mounting position, ambient temperature and supply pressure.

    8. Maintenance and Check Warning (1) After installation, repair and disassembling, connect compressed air and perform a proper function test and a leak test. If bleed noise is louder than the initial state or operation is abnormal, stop operation and check if installation is proper or not . And modification of electrical construction is prohibited due to maintaining Explosion-Protected construction function .

  • Page 21: Caution On Handling

    9 Caution on Handling Warning Operation ( 1) Do not use this positioner out of the range of its specifications as this can cause failure. (Refer to 1. Specifications.) (2) If the system is supposed to be in danger because of failure of the positioner, prepare the system with a safety circuit to avoid danger.

  • Page 25 11. Option 11-1 Pilot valve with output throttle Hunching may occur when the positioner is attached to a small capacity actuator. In such a case, use a pilot valve having a throttle for OUT1 and OUT2. The throttle is removable. (Refer to Figs.17 and 18 for mounting and dismounting the throttle.) Table 5 Throttle types Pilot unit No.
  • Page 26 In the case of side attaching, if you use fork lever assembly MX, it is compatible with our IP610 positioner in the attaching size. Also, in the case of backside attaching, if you use fork lever assembly SX, it is compatible with our IP610 positioner in the attaching size. 11-3 External feedback lever ( Type IP8000 ) Levers having different stroke sizes are available for the feedback lever of lever type IP8000.
  • Page 27 11-4 Scale plate unit Caution Locate scale plate with care not to make finger pinched between needle and plate. Adjustment of scale plate Perform adjustment of zero span in positioner before installing the positioner to either face of DA or RA with consideration of operating direction. Refer to Fig. 21. Stop positioner at intermediate opening of actuator (where input signal of 50% finishes to enter to the positioner) and adjust the position of needle to meet with 50 % of scale plate.
