Page 3: Overview
XZA series can be divided into five different seating number types and they are XZA2, XZA3, XZA4, XZA5, and XZA6. Also, XZA series can be divided into basic type, basic integral type, explosion-proof type and explosion-proof with integral type. -
Page 4: Product Structure
3.7 Local control mechanism: please notify us if users intend to order local control mechanism; for the basic type and explosion-proof type of XZA series, local control mechanism is mechanical buttons on the control box cover; for the integral basic type and explosion-proof integral type of XZA series, the local control mechanism is knob switch on the side of the electric wiring box cover. - Page 5 must operate according to relevant stipulation. Please read this operation manual carefully before installation. Controlling lines and power lines should be separately put in the grooves. The output controlling signal lines should apply shield cables and the shielding layer should be single-end earthed. 5.1 Wiring means of basic type: (basic integral type is the same.) 5.1.1 Open connection box or case of control box with terminal board.
- Page 6 and successively through No.12, 14, 12. 5.2.4 Please connect cable core wire with the wiring fastener on the terminal board. 5.2.5 According to the wiring number of electric schematic diagram, connect the core wire which with fasteners with the terminal boards correctly. Fasten each gland bolt. 5.2.6 The grounding core wire should be connected with interior grounding bolt.

5.3.5 Cable should be set up correctly to avoid the rain leaking into the electric actuator (In Fig.3, the first two connection patterns are right.) 6. Debugging Cautions before debugging: ★ The maximum control torque had been set up and sealed off with torque plate for the products before delivery. - Page 8 6.2 Precise stroke adjustment If, when the valve is electrically operated, the stroke switch controlled end point position (full closing or full opening) of the valve is unsatisfactory, precise adjustment should be performed to get perfect position precision. The way of precise adjustment is to adjust the cam action in a little delay for incomplete opening or closing or to adjust the cam action in a little advance for a little excess opening or closing.
- Page 9 manual operation, set down carrier rod and turn opening adjustment shaft of counter clockwise to make cam return to the position shown in Fig.5. And then, according to the adjustment amount, go on turning the shaft for more turns clockwise, so as to provide the counter enough adjustment amount. Now turn and lift carrier rod again and go on with item e.

provided as user required. 8. How to select priority control mode for valve closing end position Both stroke control and torque control can control valve closing. Take one as priority control and the other as protective control. Select different priority control mode for different types of valve. - Page 13 manual/electrical handwheel, in case that the actuator would be damaged. 10.10 Fasten the screws on the control box cover and wiring box cover after product debugging. After some strong vibration, please make regular check to make sure whether it is reliable. Sealing structure cannot be damaged at the same time. Tightness should be confirmed.
