VT 5004S 2X
Proportional Amplifier(for Manual The Operation)
The usage of the amplifier
1. This amplifier can supply +9V(16A, C) and –9V(14A or 26C) flat voltage.
Besides self voltage supply, +9V can be supply voltage signal to external
potentiometer.
2. When the differential motion signal from program controller (PLC) or the
computer, the bit shift of the solenoid can be controlled by the 0-+10V
voltage input from 22A and 24 C.
3. There is two pair of testing hole for nominal value (0-+6V) and real value
(0- -6V), through voltage value of the testing hole for the nominal value,
the monitoring for the input voltage can be realized. When the input
voltage is 0-+9V, the nominal value from the testing hole is 0-+6V. When
the real value is zero, the spool should be zero position. When the real
value is -6V, the spool should be at the Max.strock. . If the spool is in the
middle, the real valve should be between the 0- -6V. The nominal value
and the absolute value o the real value should be equivalence. It is also
the way to test if the amplifier is work or not.
4. There are potentiometers that can adjust the ramp time, it can adjust the
rise time and fall time separately. When the input voltage to the
Max.value (+9V), the rise time is the Max. value. If no special
requirement, the Max. ramp time is 5 second.
If the power unit do not need the ramp time:
(1). Counterclockwise rotate potentiometer for the ramp time to the
minimum
(2). Switch on the relay, Short circuit the ramp circuit (short circuit 8A
and 28A)
(3). Short circuit 30Cand 32C
5. If the amplifier and bit shift shut down or improper connection. The
feedback shut down led light, the cable failure identification will key off
the current in the solenoid.
Ⅲ. Caution
1. If there is spool vibration, it is caused because there is air in the valve
usually. You can pulse on the hydraulic circuit, open the air bleed screw,
let the spool alternating motion till the air was exhausted.
2. The voltage of <MO> port (18A,C) is compared with the input voltage
0V(10A, C) increase +9V, never short- circle them.
Ⅳ. This amplifier is European standard 32 pin (5.08X5.08mm). VT-3002B
and VT1516B holder can match with this amplifier.

amplifier. It means that programmable controller (PLC)
should not use the same power with the amplifier.
