Micro Pulse Instructions
MICRO PULSE
Micro Pulse valves are available on models:
WSB MB
with optional VERTICAL VALVE MICRO PULSE valves.
WSB 122 / WSB 140m2
with optional SLIDE GATE MICRO PULSE valves.
WSB 131 / WSB 140m1
with optional SLIDE GATE MICRO PULSE valves.
WSB 140Rm1 / WSB 140Rm2
with optional VERTICAL VALVE MICRO PULSE valves.
WSB 240Rm1 / WSB 240Rm2
with optional VERTICAL VALVE MICRO PULSE valves.
WSB 440Rm1 / WSB 440Rm2
with optional VERTICAL VALVE MICRO PULSE valves.
These models may use our "MICRO PULSE" metering system for Color and Additive components.
PULSED OUTPUT parameters control the on/off timing, or pulsing, of the valves. The controlling
parameters are the "_PO" component parameters.
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.
We have already done this. No further adjustment should be necessary.
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 *83 function, Progressive Metering, for improved accuracy so
long as the additional time necessary for Progressive Metering exists. Read about more about *83 in the
Star Functions section.
