Technical Requirements
1. The power supply voltage of the positioner is 24V DC ±10%. Please verify the power supply voltage before connecting the
power cable to the electrical terminals.
CAUTION: Make sure that the power supply is disconnected before connecting the power cable. High voltage will damage the
unit.
2. Air supply use specification
a) The air pressure should be less than 101.5 psi (0.7MPa).
Install a 5-micron filter (filter regulator), prior to the air supply inlet of the positioner to prevent moisture or oil from entering. In
the condition of highly lubricated air, it is recommended to additionally install a 3-micron oil separator in front of the air supply
inlet of the positioner. It is suggested to use a filter regulator such as Parker model number P31EB92EGBBN5P.
3. Waterproof electrical connectors use specification
a) The electrical connectors have keyed design. Please connect the electrical female connector with the electrical male
connector of the positioner according to the sign X1 and sign X2. Excessive torque will damage the electrical male
connector.
b) The cable diameter which is compatible with the waterproof electrical connectors is PG7 (4mm-6mm). Please use the
multi - core cable with external insulation, otherwise the electrical connectors cannot achieve IP66 protection class.
Below shows the correct and incorrect methods of wiring the connectors.
c) If the electrical male connectors are not used for a long time, please install silicone plugs in the female connectors and
screw them into the male connectors to prevent water or corrosive gases from corroding the connector pins or
entering the positioner inside. See pictures below.
