Piping
Do not touch near the actuator axis when supplying air after piping.
1. Perform sufficient pipe flushing and remove cutting chips, oil and dust from the piping to
prevent foreign matter from entering the positioner.
2. When connecting an SMC fitting to an air connection port (SUP, OUT1, OUT2), apply a
tightening torque of 12 to 14Nm. The tightening torque must be suitable for the tube fitting
in use.
■Selecting OUT1 / OUT2 Port
Table 6 shows output condition of OUT1 and OUT2 port when input current is cut while supply
pressure continues to be supplied. Output condition of OUT1 and OUT2 shall be considered for
when piping if actuator direction is specified when input current is cut.
■Piping
*1
Piping shall be based on “■Piping Layout” after checking actuator specification and operating
direction, and select the port for positioner with “■Selecting OUT1 / OUT2 Port”.
■Piping of Double Acting Actuator
OUT2 port of IP8001 smart positioner is plugged at ex-factory condition. To connect the positioner
to double acting actuator, unplug OUT2 port and connect piping according to “■Piping Layout”.
1: The positioner operating direction can be changed by the parameter settings (parameter code: 200). For
parameter details, refer to “■Parameter Code Detail”. At such times, changing the piping is unnecessary.
The settings described in this section decide the operating direction via the appropriate parameter
settings (dir).
