COMMISSIONING INSTRUCTION FOR

CABINET WITH SERVO CARDS

xSVI/O

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

XSV

System program is for XSV module commissioning.

57600 8 1

XSV

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.

After getting connected, enter help then the picture

is presented to show the communication is available.

Step 1 for commissioning is to check inner parameter

of module.

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.

voltage of the terminal board 10 26 or

11 27 ,adjust potentiometer W7 and have the

output current and voltage of terminal board

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

in open-loop. After commissioning, set closewill be
