current and dither frequency
according to the valve
specification.

Enter UP or DOWN ramp times.
 “Change Settings” to apply the
changes to the unit’s temporary
memory.

Once the system is running, fine
tune these settings.
Always Active (ON) – Output A is always active and cannot be set “OFF”.
Coil B – active (ON/OFF) – Enables/Disables Output B.
Current feedback (ON/OFF)
 When Current Feedback is “ON”, coil current output is monitored and adjusted proportionally to the demand
within the coil max and min settings.

Current Feedback compensates for supply voltage and coil temperature changes. When disabled, the output’s
waveform is adjusted proportionally to the demand between 0% and 100% PWM Duty Cycle.
Inverted (ON/OFF)
 When Inverted is “ON”, the output is inversely proportional to the input. This is used with normally closed valves.

When Inverted is “OFF”, the output is proportional to the input.
