Piping and Wiring work
•
Use dry and clean instrument air for the operation source of the actuator.
•
An appropriate pipe diameter shall be used for instrument air supply piping to such instruments as
positioner, booster relay, etc. so that air pressure will not decrease in piping.
•
If order was placed with requirement for mounting of such accessories as positioner, booster relay,
solenoid valve, the air supply piping from these accessories to the actuator has been completed
prior to shipment. So be careful not to damage the piping.
•
If the actuator is equipped with an accessory, follow the instructions in the operation manual of each
device in instrument air supply piping and instrument wiring.
•
Do not use a seal tape for the instrument air supply piping port to an accessory because tape
chips may clog in the piping, causing malfunction of accessory.
•
Do not install wiring on a rainy day or in an environment subject to splash of water to avoid electric
leak or damage of the devices.
•
Use wires, which have sufficient capacity for keeping the good function of the accessories.
•
Perform reliable wiring work to prevent entry of water or rainwater from external cable inlets.
(1)
For direct connection of signals 3 ~ 14 psig (0.2 ~ 1.0kg/cm2G) from controller to the actuator
Connect an air piping to the instrument air inlet shown in the structural drawing in the “Structure”
section.
(2)
For actuator fitted with accessories
Connect pipes and wires to the instruments, referring to the manuals for the accessories to the actuator.
