Micro Pulse Instructions

Optional MICRO PULSE valves for low dosing (10 g or less) and are available as a VERTICAL VALVE on removeable
hoppers and also as a HORIZONTAL SLIDE GATE dispense device. These instructions are for blenders equipped
with a Micro Pulse device. Do not set the PO parameter if your blender not equipped with a micro pulse device.
MICRO PULSE are typically installed on the 3
PULSED OUTPUT parameters control the on/off timing, or pulsing, of the valves. The controlling
parameters are the "PO Pulsed output / timing" component settings.
When set to 00000, normal slide gate operation occurs. When set to a value, such as 00101, power will
pulse ON then OFF, at 1/10 second time intervals each way. This ON/OFF cycling will repeat for the entire
dispense time.
When using a MICRO PULSE valve, you must set the related PO parameter to 00101.
If overall blender throughput is too low, you may increase the metering rate of each Micro Pulse device by
adjusting the cylinder airflow control valves for higher flow rate. This causes more rapid movement of the
cylinder, ejecting more pellets per pulse. The drawback is noisy operation.
We recommend air flow be adjusted for quiet operation but assuring full valve movement per on/off cycle.
The approximate correct airflow adjustments are:
At nose of cylinder, 1.5 full turns out from full closed.
At rear of cylinder, 2.5 full turns out from full closed.
MICRO BLENDER slant valves, adjust by sound.
On fixed hoppers with horizontal micro pulse valves, CLEAN OUT of the hopper can be accomplished by
opening the "clean out" port provided under the valve. Turn to one side to allow material to drain.
MICRO PULSE - ACCURACY
All MICRO PULSE valves are more accurate if the associated PT parameter is set to 00090. Read PT
parameter in the PARAMETER section. Use Options / Special Functions / Operating Options / Progressive
Metering, for improved accuracy so long as the additional time necessary for Progressive Metering exists.
Read about more about Progressive Metering in the Controller Functions section.
