Output A or B Coil Settings
Select Coil B Active for a Dual Coil Valve
Control.
Enter minimum and maximum current, dither
frequency according to the valve spec.
Enter ramp times.
“Change Settings” to apply the changes to the
unit’s temporary memory.
Fine tune these settings as required.
Always Active
(ON) – Output A is always active and cannot be set to 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 the current due to 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 outputs are inversely proportional to the inputs. This is used with normally
closed valves.
When Inverted is “
OFF
”, the output is proportional to the input.
Coil A/B Min Current
(0 to 3Amps)
Determines the min current or duty cycle when the demand is
>
0. Fine tune it to balance machine
safety and valve responsiveness.
