Safety
➢
Before connecting terminal, ensure that the power is off completely.
➢
Please use ring terminal 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 positio
ner’s minimum ampere of input signal is 3.8 mA but
maximum ampere of input signal should be 24mA or under.
➢
Compliance voltage of current source must be Min. 10V and Max. 28V. If the length of the supply
cable between the current source and the positioner is long, or if there is a filter or safety barrier,
then consider using a current source which could supply higher Compliance voltage.
➢
Positioner with PTM options must be supplied with
9~28V DC
separately. For mechanical limit
switch option, separate
12~30V DC
must be supplied. For Proximity limit switch option, separate
8.2V DC
must be supplied.
➢
DO NOT connect Voltage source (9~28V DC) to Input (4~20mA DC) terminal (IN+, IN-) as it will
cause PCB failure.
➢
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.
