5.0 Start-Up
1. Turn the compressed-air to the dust
collector's compressed-air manifold ON. Use
the compressed-air regulator to adjust to
90- psig. Pressure of 90 to 100-psig is the
most typical setting for satisfactory cleaning
performance. See Section 6.0, Operating
Adjustments. The lower the compressed-air
setting, the less pulse-valve air consumption
will be.
2. Turn the blower fan motor ON and check the
rotation by referencing the rotation arrow
decal on the blower fan housing. Rotation
should be clockwise looking down from the
top of the blower fan motor.
3. Adjust the blower fan for proper system
airflow by adjusting the volume control
damper on the chamber silencer discharge.
6.0 Operating Adjustments
6.1 Delta P Control Calibration
The only user calibration is the zero adjustment
of the display. Due to slight changes in either
electronic components over time, or pressure
differentials within the plant environment,
occasionally the display may show something
other than 0.0 while at rest. Use the following
procedure to recalibrate the operating system.
1. Power the control for a minimum of thirty
(30) minutes to stabilize the operating
pressure.
2. Remove power from the control so that the
display shuts down.
3. Press and hold the LOW SET, HIGH SET,
and ALARM SET keys while reapplying
power to the control. Continue to hold these
keys while the control goes through a
power-up routine. This is indicated by
sequentially displaying "8" in each digit, and
then displaying "0.0" (see Figure 3, Delta P
Control Display).
4. Release the three keys. The new calibration
automatically stores in the memory.
NOTE
Too much airflow can cause electrical
system failure and result in eventual blower
motor failure.
Stand clear of blower fan exhaust area, as
debris can be exhausted and cause injury.
