Function:
The Soft Shift Controller introduces a current ramp
permitting the soft start of proportional solenoid valves used for pressure or
flow control in hydraulic circuits. When the unit is powered on, it ramps to
full current output over the ramp on time period that is adjustable within a
factory set range. When the power is switched off, output of the unit falls
immediately to zero. It is available in an IP65 rated DIN 43650 coil mount
version.
Features:
- Cost effective alternative for soft start of
proportional hydraulic circuits
- Broad range of supply voltages (9 to 32 VDC)
- Modern technology utilizing high frequency switching
output (PWM)
- Current output is 650 mA or 2 A (adjustable)
- Current sensing circuit maintains output regardless of
changes in input voltage or coil resistance
- Ramp on time (adjustable)
- Rugged construction to withstand harsh
environments
- IP65 protection class

* Note 1: Match power supply voltage with
rating of solenoid coil. Operating the controller with a supply voltage lower
than the solenoid rated voltage may result in reduced current output. The
current output of the controller should not exceed the current rating of the
solenoid coil.
Note 2: The coil should have no polarity or protection diodes for proper
operation of the device.
Adjustments:

Use a small screwdriver to loosen the mounting screw
and remove the transparent lid. The single turn trim pots are adjusted with a
Phillips #0 sized screwdriver.

Mounting:
1. Ensure the lid, compression washer, o-ring and base gasket are correctly in
place (necessary for IP65 protection).
2. Ensure that no damage or injury can occur on the machine when the valve is
operated.
3. Attach the soft shift controller to the load and tighten the mounting screw.
4. Connect the cable to the power supply (red is power +, black is power -).
5. Switch on the power supply to the soft shift controller.
6. Adjust the current output and ramp on time to suit the application.
