Description:
The 0-10 VDC Connector Amplifier simplifies control of proportional solenoids
by supplying a current proportional to an input control (0-10 VDC or 0-20 mA).
This linear solenoid controller utilizes high frequency switching output (PWM)
to provide a DC current output. Maximum current output options are 2 Amps, 1.2
Amps, 600 mA or 300 mA. A current sensing circuit maintains current output
regardless of changes in input voltage or coil resistance. The user can adjust
maximum and minimum current. Ramp time, dither frequency and amplitude can also
be adjusted to match the application. It is CE certified for EMC as well as UL
and cUL listed. The unit is available with a DIN 43650 connection to mount
directly on the coil. Other versions are available with
4-20 mA or
0-5 VDC/0-20 mA/10K potentiometer
inputs. A remote mount version is housed in
a rugged metal box.

resistance selection (nominal) |
Nominal
resistance of solenoid coil should comply with:

|
* 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. Operation with a supply
voltage higher than the solenoid's rated voltage could result in solenoid
failure if output current exceeds solenoid rating.
- The coil should have no polarity or protection diodes
for proper operation of the device.

Mounting Instructions:
- Supply voltage should be between 9 and 28 VDC. 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 maximum current output of the amplifier should not
exceed the current rating of the solenoid coil.
- The coil should have no polarity or protection diodes
for proper operation of the device.
- Do not install the amplifier near high voltage relays or
other sources of electrical interference.
- Connect the power supply, signal input and valve
solenoid.
- Set the input signal 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 as follows.
For Either 0-20 mA or 0-10 VDC Control:
Turn ramp screws fully counterclockwise to eliminate ramping.
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.
Enable: When Enable is connected to the -ve power supply, the unit will
be disabled. When Enable is left open or connected to the +ve power supply, the
unit is enabled.
For wiring diagrams, obtain a copy of the
datasheet.
Adjustments:
The following settings represent a typical set up for a
voltage or current signal input operating scenario. Conditions will vary for
other set up scenarios. Use a small screwdriver to loosen the mounting screw
and remove the transparent lid. The trim pots are adjusted with a jeweler's
sized screwdriver. I min and I max are multi-turn trimpots with a range of 10
turns.

*NOTE: Range of maximum output current is 2A (maximum output current=minimum
current setting + maximum current setting).
**NOTE 2: To eliminate ramping, turn the trim pots fully
counterclockwise.
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 0 mA).
- 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 (10 VDC or 20 mA).
- 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.
Setting the Ramp Times:
- The factory setting for ramp times is the minimum (0.01
seconds) or fully CCW.
- If the ramp time settings are not needed, leave the
setting at the minimum value.
- To change the ramp times, adjust the trim pot CW to
increase the time.
- Note that rising and falling ramp times are
independent.
Ramp times are application dependent. They limit the
rate of change or how fast the operation happens. Note that if the input signal
is not applied long enough for the ramp time set, the desired solenoid current
will not be reached.
Setting the Dither Amplitude:
- The factory setting for dither amplitude is 0%
(CCW).
- To adjust dither amplitude, turn the trim pot CW until
small changes in the input signal register similar changes in current
output.
- Choose the smallest effective dither amplitude.
Dither amplitude is adjustable from 0 to 10% of the
rated maximum current. Dither amplitude and frequency are dependent on the
specific valve. The effects of static friction on the operation of the solenoid
are reduced by the application of a small AC current. The hysteresis and
repeatability of the valve are improved by this practice. The optimum dither
amplitude is attained when small input signal changes register similar changes
in current output (pressure or flow through the valve).
Setting the Dither Frequency:
- The factory setting for dither frequency is the minimum
or 0% (CCW).
- To adjust dither frequency, turn the trim pot CW until
the desired frequency is set.
- Refer to the proportional valve manufacturer's
catalogue for the dither frequency rating of a particular valve.
