Manually Opening/Closing Valve
CAUTION
•To manually open or close the valve, be
sure to disconnect the ACTIVAL from the
power supply (24 V AC). If the valve is
manually opened or closed with the power
applied, the actuator may be damaged.
•Never rotate the joint out of “0” to “100”
range of the scale.
Before manually opening or closing the ACTIVAL, make
sure it is disconnected from the power supply.
As shown in Fig. 7, hold the joint with a tool such as a
hexagonal wrench, and turn the joint slowly toward the
position to set up.

Auxiliary Switch / Auxiliary Potentiometer
(Optional)
CAUTION
•The auxiliary switch and the auxiliary poten-
tiometer are installed on site. (See Fig. 15.)
Refer to the instructions attached to them.
•Do not open the top cover except when ad-
justing the auxiliary switch or auxiliary poten-
tiometer.
•Do not put a load on the cover.
Wiring
CAUTION
•Disconnect power supply before performing
any wiring.
•This product is designed for 24 V AC power
supply voltage. Do not apply mains power.
•For correct wiring of 4-20 mA DC input and
2-10 V DC input, refer to Figs. 10 to 13 and
make sure the polarity of power supply and
2-10 V DC output. Incorrect wiring may
result in PCB (printed circuit board) burnout.
•To prevent equipment damage, cover the
actuator except during wiring work.
Wiring precautions
1) Do not apply 24 V AC to the terminals 4, 5 and 6.
(Max. applicable voltage: 5 V DC)
2) To lead the wires into the actuator, cut out a knockout
hole for a wiring port. There are two knockout holes
on the bilateral sides of the actuator terminal block:
one φ22 mm knockout hole on each side. Select a
knockout hole according to the conduit mounting
direction and cut it out by lightly knocking with a
screwdriver. (Refer to Fig. 8 )
Figure 8. Knockout hole for wiring port
3) Correctly connect the wiring to the terminals with M3.5
screws, referring to the wiring terminal diagrams
shown in Figs. 10 to 13 and the wiring examples
shown in Fig. 14. (For the wiring of the auxiliary switch
or the auxiliary potentiomenter, refer to Fig. 15.)
4) When the ACTIVAL is used in a high-humidity
environment or outdoors, use a water-proof connector.
Figure 9. Terminal cover removal
Unscrew the three screws (M4 ×10) to remove the ter-
minal cover. (See Fig. 9.)
1.Remove
these screws.
2.Remove terminal cover.
