1-4 Safety on Piping Connection
* Be care to select facility so that moisture, oil, other materials may not be mixed
in pipe of air compressor and system .
* Prevent to penetrate on moisture ,oil and different material with air regulator
which is equipped filter or separated filter device in front of supplying port on
SP760 series.
1-5 Supply pressure Condition
* Use drying air with dew point of at least 10℃ lower than ambient temperature.
* Avoid extra material using filters less than 5 micron .
* Avoid oil or lubrication oil .
* SP 760 series supply pressure range is 1.4 ~7 kgf/cm2 (140 - 700 kPa ).
Do not use over usage range
1-6 Supply Pipe Condition
* Check that different materials inside pipe must be erased before installing pipe .
* Do not use pipe which is squeezed or damaged .
* Pipeline should have more than 6 mm of inner diameter to maintain SP760 series
flow rate.
1-7 Safety Contents on Electrical connection
* Check that electric power is off before connecting terminal.
* Please use ring terminal to protect against vibration or any other impact.
* SP760 series positioner (except feed back signal internal type ) uses 4-20mA DC.
In products operation minimum supplying current, the standard type positioner is
3.2mA and HART internal type positioner's minimum ampere of input signal is 3.8mA
but maximum ampere of input signal should be 24mA or under.
* In case there is feed back option in SP760 series, separated power must be supplied
to feed back signal and supplying voltage must be 9-28V and not exceed into
maximum 30V.
* In order to protect products, positioner should be grounded.
* Please do not install the cable near high noise equipments such as high-capacity
transformer or motor.
* Cable and cable glands suitable for at least 90℃ shall be used.
* Use fasteners with yield stress ≥ 626 MPa.
* When installing a cable gland or blanking element, use an explosion-proof product rated
IP66 or higher.
