xSV
Servo card cabinet
consists of 4 xSV modules,4
x SV terminal boards and 2
power modules. xSV
modules collect I/O signals
from the field which will be
calculated based on the
designed controlling
strategy so as to control the
valve directly via xSV
terminal boards. xSV

The xSV module functions to control high-pressure actuator so thateliminates the needs of CPU commands. 4~20mA command signal will
be sent to control the opening of HP actuator valve, in turn, the 4~20mAfeedback signal would also be sent to DCS. xSV module can be inserted
and pulled out when the cabinet has electric. Parameters of xSV modulecan be changed directly online through special software.

Servo valve control module aims to regulate servo
valve PI with 2-way 24V redundant power supply. With the
help of XSV-TB, each module can receive 2-way LVDT
signals, 2-way 0-20mA signals, 2-way 40mA servo

Terminal board of servo valve control assists the
module of it with 24V power supply. With the help of XSV
module, each terminal board can receive 2-way LVDT
signals, 2-way 0-20mA signals, 2-way 40mA servo
current output, 2-way 0-20mA current output,8-way digital
input and 1 digital input.

First, open super terminal program and use related
serial ports, then set the amount for each second as
57600,data bit as 8, check as no, stop bit as 1,
data flow control as no and communicate with XSV
communication.

Step 2 for commissioning is to wiring outside of
terminal board.
1. check if wiring outside of terminal board is correct.
2. check if wiring outside of terminal board is
grounded
Step 3 for commissioning is to check linkage of valves
and set main parameters of module.

set close
The command set ol is to force valve be closed and
the command set oh is to force valve open. Both
commands are come into effect when set openare

the command signal value, PVH---the max figure of
output from valve, PV1---the 1st LVDT data and PV2---
the 2nd LVDT data. All are displayed as hexadecimal
whose range is 0000FFFF. According to that, the
