Safety
Before connecting terminal, ensure that the power is off completely.
Please use ring-type rug to protect against vibration or any other external impact.
Positioner usually uses 4~20mA DC. Minimum ampere of input signal of standard type
positioner is 3.5 mA
and Hart internal type positioner’s minimum ampere of input signal
is 3.8 mA but maximum ampere of input signal should be 24mA or under.
Positioner with PTM options must be supplied with 9~28V DC separately. For L/S
option, separate 12~24V DC must be supplied.
For both options, it should not
exceed 30V DC.
Positioner should be grounded.
Please use twisted cable with conductor section are 1.25mm
2
and that is suitable for
600V (complying with the conductor table of NEC Article 310.) The outer diameter of
the cable should be between 6.35 ~ 10mm. Use shield wire to protect against electro-
magnetic field and noise.
Please do not install the cable near high noise equipment, such as high-capacity
transformer or motor.
