VT 5006BS20
Proportional Amplifier(for Manual The Operation)
0—9V, the nominal value should be 0-+6V. The position of the spool can
be monitored according to real value. 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. stroke. . The absolute value of the nominal
value and real value should be equivalence. It is also the way to test if the
amplifier is work or not.
4. There potentiometer on the amplifier used for adjusting the ramp time. If
the system do not need the delay time, you can counterclockwise rotate
the potentiometer to the end, or short circuit 8A and 10C, or switch on K5
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 two solenoids.
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 zero reference （ MO ， 26C ） compared with the input voltage
0V increase +9V, never short- circle them.
Ⅳ. This amplifier use European standard 32 pin (5.08X5.08mm). VT-3002B and
- 30 -
VT1516B holder can match with this amplifier
