REMOTE MOUNT SOLENOID DRIVER
(0-10 VDC Input Version)

Description:

The Remote Mount Solenoid Driver simplifies remote control of proportional solenoids. The unit accepts 0-10 VDC or 0-20 mA signal inputs and a wide range of power sources from 9-28 VDC. This linear solenoid driver utilizes high frequency switching output (PWM) to provide a DC current output. Options for maximum current output include 2 Amps, 1.2 Amps, 600 mA or 400 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 be adjusted to match the application. A system of LEDs indicates output power level, input power level and power on/off. It is CE certified for EMC. The unit is available as a stand alone PCB board, as a packaged driver enclosed in an IP65 or IP67 rated metal housing with cable provided or with 3 connectors. An industrial module in a DIN rail mount housing is available. OEM versions are available. The valve driver is designed for remote mounting. Other versions are available including 4-20 mA and 0-5 VDC/0-20 mA/10K potentiometer control input versions as well as a DIN 43650 coil mount version.

Function:

The Remote Mount Solenoid Driver supplies a solenoid valve with current proportional to an input control (0-10 VDC or 0-20 mA).

Application:

Accurate control of hydraulic and pneumatic proportional solenoid valves used in mobile construction equipment and industrial processes.

Mounting Instructions and Wiring Connections:
For stand alone PCB Boards:

Mounting the board:

  • The board will accomodate #6 size mounting screws (not supplied).
  • Use a cable to connect to the driver with each wire stripped to 6.5 mm (1/4 inch) and the shield (jacket) stripped to permit splaying of the wires in the screw terminal without tension. The exposed ground shield wire should have a heat shrink placed around the wire as a precautionary measure.
  • Reference the label (included with the board) for the pin out connections of the screw terminals. Size 16-20 AWG wire is recommended for the power and output conductors. Size 18-24 AWG wire is recommended for the signal conductors.
  • To connect the cable to the board, loosen each screw terminal, wrap the wire around the screw and tighten with a jeweller's sized screwdriver. Take care to position the ground shield wire away from the PCB board.

For Packaged Drivers with/without cable (Metal Box):

Mounting the housing:
Mount the housing using four #10-32 bolts or screws.

Connecting the cable:
For models where the cable is supplied, connect the cable to the load, power supply and input signal as follows.

For either 0-20 mA or 0-10 VDC control:
Turn ramp trim pots fully counter clockwise to eliminate ramping.
Use Imin trim pot to set minimum speed with minimum control input.
Use Imax trim pot to set maximum speed with 100% of control input.

Connecting a cable to the screw terminals on the board:
For models where no cable is provided, connect a cable as follows. For a cable specification, refer to the technical specification section.

  • To access the screw terminals, loosen the four screws on the lid using a Phillips #1 screwdriver. Remove the lid.
  • Use a 0.200 to 0.312 inch diameter solid round shielded cable to connect to the driver. Each wire should be stripped to 6.5 mm (1/4 inch) and the shield (jacket) stripped to a minimum of 57 mm (2-1/4 inches). Exposed ground shield wire should have a heat shrink placed around the wire as a precautionary measure.
  • Remove the clamp nut on the Heyco PG9 grommet using an adjustable wrench.
  • Slide the clamp nut over the cable. Insert the cable into the grommet, allowing for the stripped minimum of 2 1/4 inches to be available inside the housing. Tighten the clamp nut securely attaching the cable to the housing assembly.
  • Reference the label (found on the inside of the lid) for the pin out connections to the screw terminals. The wiring connections diagram (see previous section) shows the appropriate connections for each control option.
  • To connect the cable to the board, loosen each screw terminal, wrap the wire around the screw and tighten with a jeweller's sized screwdriver. Take care to position the ground shield wire away from the PCB Board.
  • Replace the lid and gasket. Replace and tighten the four 4-40 Phillips flat head screws.

3 connector pin out

For DIN rail mount Drivers:

Mounting the housing:
The DIN Rail Mount Driver has a universal foot for mounting on the DIN rail.

Connecting to the screw terminals on the board:

  • Use 16-20 AWG wire for the power conductors and 18-24 AWG wire for the signal conductors in a solid round shielded cable to connect to the remote mount solenoid driver. Each wire should be stripped to 6.5 mm (1/4 inch) and the shield (jacket) stripped to a minimum of 57 mm (2-1/4 inches). Exposed ground shield wire should have a heat shrink placed around the wire as a precautionary measure.
  • Reference the label for the pin out connections of the screw terminals.
  • To connect the cable, loosen each screw terminal, insert the pre-tinned wire and tighten with a jeweller's sized screwdriver. Take care to position the ground shield wire away from the PCB Board.

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.

Adjustment Details:

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. Adjustments are accessible by loosening the four screws on the lid of the housing and removing the lid. Ensure that the unit is connected to an operating proportional valve. Use a Phillips #1 screwdriver to make adjustments to the trim pots.

Setting the Minimum Current (Imin)

  • Set the minimum current before setting the maximum current.
  • Apply minimum input (0 V or 0 A).
  • 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 V 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.

ramp diagram

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 valve manufacturer's catalogue for the dither frequency rating of a particular valve.

Troubleshooting:
Diagnostic LED's: Input Level and Output Level green LED's vary in intensity following the control signal input and output to the valve. Power OK green LED indicates power supply is connected.
