7.Caution on Handling

■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.
(1) Do not touch the actuator and operating part of the valve when they are pressurized. as this
can be dangerous.
(2) Take care not to get your fingers caught during mounting or positioning the cam. Stop
supplying pressure beforehand to release compressed air in the positioner and actuator.
(3) Be sure to operate the positioner with the body cover unit mounted.
(4) Flush the inside of the piping while connecting it so that foreign matter such as cutting debris
does not enter into the piping.
(5) The opening degree of the actuator may be unstable if a booster relay is used.
(6) When a pressure gauge is used with the positioner, use it as a reference only.
(7) When frozen air is supplied to the internal mechanical parts of the positioner, the behaviour of
the pressure gauge indicator will become unstable.
(8) The positioner is a product that performs stationary control.
Do not use it with high frequency ON-OFF.
For operators
■
(1) Read and understand the operation manual carefully before assembling, operating or
providing maintenance to the product.
■Handling
(1) Avoid giving impact to the positioner force to leads to failure. Handle with care during
transport and operation.
(2) If the positioner is left unused at the operation site for an extended period, ensure the body
cover unit is fitted, and mount a plug on the piping ports.
If the atmosphere is of high temperature or high humidity, take measures to avoid condensation.
The condensation control measures must be taken thoroughly for exportshipment.
(3) Since zero-point varies depend on mounting position , zero-point should be adjusted after
installing.
