Part No.:
Connector Amplifier
CAPVE-H-5V-xA-5C-2M
Where x=1 (1 Amp output version) or 2 (2 Amps output version)
Function:
The Connector Amplifier - coil mount supplies a solenoid valve with current
proportional to an input control (0-5 VDC or command potentiometer).
Application:
Accurate control of hydraulic and pneumatic proportional solenoid valves used
in mobile equipment and industrial hydraulic or pneumatic circuits.

|
Description:
The economy version of the Connector Amplifier simplifies control of
proportional solenoids by supplying a current proportional to an input control
(0-5 VDC or 10K potentiometer). It accepts power supply voltages from 9 to 32
VDC. This linear solenoid controller utilizes high frequency switching output
(PWM) to provide a DC current output. Maximum current output is 2 Amps. A
current sensing circuit maintains current output regardless of changes in input
voltage or coil resistance. The user can adjust maximum and minimum current.
Dither frequency and amplitude are factory set to 250 Hz. In this economy
version of the connector amplifier there are no ramps. The unit is available
with a DIN 43650 connection to mount directly on the coil and comes complete
with 2 meters of unterminated cable.

* Note:
- Match power supply voltage with rating of solenoid coil.
Operating the amplifier with a supply voltage lower than the solenoid rated
voltage may result in reduced maximum current output.
- The coil should have no polarity or protection diodes
for proper operation of the device.
- Do not exceed the current rating of the solenoid coil
with the maximum current output of the driver.
- Range of maximum output current is either 2A or 1 A
(maximum output current=minimum current setting + maximum current setting).
The single turn trim pots are adjusted with a Phillips#0 screwdriver.
Mounting Instructions:
- Supply voltage should be between 9 and 32 VDC. Excess
voltage will damage the unit. Match the power supply voltage with the voltage
rating of the solenoid coil. Operating the amplifier with a supply voltage
lower than the solenoid rated voltage may result in reduced maximum current
output.
- The coil should have no polarity or protection diodes
for proper operation of the device.
- Do not exceed the current rating of the solenoid coil
with the maximum current output of the driver.
- Do not install the amplifier near high voltage relays or
other sources of electrical interference.
- Connect the power supply, signal or control pot input
and valve solenoid.
- Set the input signal or potentiometer to the maximum
level and confirm it is operating properly.
- Ensure the transparent lid is firmly in place. Ensure
the brown rubber base gasket is in place, providing a seal between the
amplifier and the plug on the valve. The mounting screw, compression washer and
o-ring should be flush with the top of the lid and fastened in place.
- Tighten the screw to make a firm connection to the valve
with a Phillips #2 screwdriver.
Connections:
Connect the cable conductors to the power supply and input signal or
potentiometer, as follows.
For Potentiometer or 0-5 VDC Control:
Use I-Min. screw to set up minimum speed with minimum control input.
Use I-Max. screw to set maximum speed with 100% of control input.
For wiring diagrams, request a faxed copy
of the datasheet.
Adjustments:
Adjusting the minimum current will shift the maximum
current as shown.
 |
Adjusting the maximum current does not affect the
minimum current setting.
 |
Setting the Minimum Current (Imin):
- Set the minimum current before setting the maximum
current.
- Apply minimum input (0 VDC or control pot at
minimum).
- The factory setting for the Imin trim pot is 0 or fully
counter clockwise (CCW).
- If the desired minimum current is greater than 0, adjust
the trim pot clockwise (CW) until the desired current is achieved.
The minimum current setting can be used to take into
account the mechanical valve deadband and provide desired offsets from zero to
allow full control within the functional range of the specific valve.
Setting the Maximum Current (Imax):
- Apply maximum control (5 VDC or control pot at
maximum).
- The factory setting for the Imax trim pot is 100% or
fully CW.
- Turn the trim pot CCW to adjust the current setting
downwards to the desired maximum.
The maximum current setting is adjusted to meet the
customer's working pressure or flow range to the full scale signal input range.
This provides maximum control for a specific application.
