1-3 Precautions
Be sure to read before handling.
Operation
Warning
1. Do not operate the positioner outside the specified range as this may cause problems. (Refer to
the specifications.)
2. Design the system to include a safety circuit to avoid the risk of danger should the positioner
suffer failure.
3. Be sure that exterior lead-in wiring to the terminal box is based on the guidelines for explosion-
protection of manufactory electric equipment when being used as a flame proof, explosion proof
construction.
4. Do not remove terminal cover in a hazardous location while the power is on.
5. Covers for the terminal and body should be in place while operating.
6. When using as an intrinsically safe explosion-proof product, do not wire in a hazardous location
while the power is on.
Caution
1. Do not touch the actuator or valve's oscillating section when supply pressure has been added, as
this is dangerous.
2. Make sure fingers do not get caught when mounting and aligning the cam.
Cut off the pressure supply and always release the compressed air inside the positioner and actuator
before performing this work.
3. Always use with the body cover unit mounted.
Moreover, the positioner may not meet degrees of protection IP66 depending on the body cover
mounting conditions. In order to meet degrees of protection IP66, tighten threads using the proper
tightening torques (2.8 to 3.0 N·m).
4. Always flush the pipe's inside before piping to ensure foreign objects such as machining chips do
not enter the positioner.
5. The actuator opening may become unstable when using the booster relay.
6. Always use a ground connection to prevent noise from the input current and to prevent damage
because of static electricity.
7. Use the pressure reading on the supplied pressure gauge as an indication.
8. The supplied pressure gauge's needle will malfunction if the pressure supply to the internal
mechanism or positioner freezes. Ensure that the pressure gauge's internal parts do not freeze if
using the pressure gauge in an operating environment with an ambient temperature of less than
0°C.
For users
Caution
1. Assemble, operate and maintain the positioners after reading the operation manual tho-roughly
and understanding the content.
