Ⅱ. How to use: Refer to connecting iagram
 Amplifier an external wiring connection
1. The electrical supply shoul be D.C.24V
The point22A or 22C connecte to the positive pole of the electrical supply.28A
or 28C connecte to the negative pole of the electrical supply.
2. The connection of between the amplifier an solenoi .
The two ports of the proportional solenoi A shoul be connecte to 2A
an 32A separately.
The two ports of the proportional solenoi B shoul be connecte to 2C
an 32C separately.
Remark: (1).there is no irectionality in the wire connecting.
(2). Solenoi A is the one with a shift sensor, Solenoi B is the one
without shift sensor.
3. The connection with the bit shift sensor: the amplifier shoul be
connecte to the bit shift sensor with the shiel cable.
10c shoul connect to the port 1 of the bit shift sensor.
30c shoul connect to the port 2 of the bit shift sensor.
8c shoul connect to the port ┴ of the bit shift sensor.
Screen all the input lines. Leave one en of the screen open. Connect
one en to 28A or 28C
4. The input of the control voltage signal
5. (1). 4 manual input ports for the input of voltage can be preset

a. When you use preset potentiometer P1 to input ±9V electric signal,
14C is signal input en , Switch on relay K1. It means short-circuit
24C(+24V) an 12C.
b. When you use preset potentiometer P2 to input ±9V electric signal,
14A is signal input en , Switch on relay K2. It means short-circuit
24C(+24V) an 12A.
c. When you use preset potentiometer P3 to input ±9V electric signal,
20A is signal input en , Switch on relay K3. It means short-circuit
24C(+24V) an 16A.
. When you use preset potentiometer P4 to input ±9V electric signal
4, 20C is signal input en , Switch on relay K4.It means short-circuit
24C(+24V) an 16C.
The four input en is optional, while P4(20C) is preferential
Remark: when you choose one of the input port, the relevant re LED
will light to in icate it is the currently input port.
(2). 0 - ±10V ifferential motion voltage input en .
If the control voltage signal from PLC, input 0-±10V signal from 6A an
6C.
 The usage of the amplifier
1. The amplifier have stable +9V(26A) an –9V(24A) voltage signal as the
input level, which can be applie for the 4 optional manual input signal.
Positive signal control solenoi B, negative signal control A.
There are two control patterns:
a. To preset one –four potentiometer, choose the ifferent circuit
accor ing to the programming. Directly input +9V(26A) or -9V(24A)
voltage
b. External potentiometer, one port connect MO (26C), one port connect
+9V or -9V, the sli ing port connect to input port, it can be manual
regulate .
Remark: you can gain +9V voltage or -9V voltage from K6, the automatic
conversion of the polarity of the voltage can be realize , an the two
solenoi s can be controlle .
2. The 0±10V ifferential motion signal from program controller (PLC) or the
computer input from 6A an 6C, the solenoi A or solenoi B can be
controlle .
Caution: never connect 6A or 6C any port of the amplifier. It means the
program controller an the proportional amplifier can not use the one
power or have the same groun point.
3. There is two pair of testing hole for nominal value (0-+6V) an real value
(0- -6V), through voltage value of the testing hole for the nominal value,
the monitoring for the input voltage can be realize . When the input
voltage is 0-+9V, the nominal value is 0--6V. When the input voltage is

0—9V, the nominal value shoul be 0-+6V. The position of the spool can
be monitore accor ing to real value. When the real value is
- 30 -
zero, the spool shoul be zero position. When the real value is +6V, the
spool shoul be at the Max. stroke. . The absolute value of the nominal
value an real value shoul be equivalence. It is also the way to test if the
amplifier is work or not.
4. There potentiometer on the amplifier use for a justing the ramp time. If
the system o not nee the elay time, you can counterclockwise rotate
the potentiometer to the en , or short circuit 8A an 10C, or switch on K5
5. If the amplifier an bit shift shut own or improper connection. The
fee back shut own le light, the cable failure i entification will key off
the current in the two solenoi s.
Ⅲ. Caution
1. If there is spool vibration, it is cause because there is air in the valve
usually. You can pulse on the hy raulic circuit, open the air blee screw,
let the spool alternating motion till the air was exhauste .
2. The voltage of zero reference （ MO ， 26C ） compare with the input voltage
0V increase +9V, never short- circle them.
Ⅳ. This amplifier use European stan ar 32 pin (5.08X5.08mm). VT-3002B an
VT1516B hol er can match with this amplifier
