The Pulse-Bac 2000 Series Dust Collection Equipment comes
shipped on a 48”x 45” pallet, bolted down and held in place
by two 16 gauge steel plates located in the front and back,
underneath the bottom platform. You will need to have a 7/16
socket wrench to remove the dust collector from the pallet.
First inspect your new Pulse-Bac for
any damage during shipping. Check
the following:
1. Check for visual damage, if visual damage is apparent have the driver note that on the Bill of Laden. If
the driver has left the facility before visually inspecting the equipment and damage is apparent, immediately call the shipper and have them return to inspect
and note the damage. Whenever possible note the
damage by taking pictures. This will aid you if a claim
must be submitted for damage or replacement.
2. Check your “ Tip-N-Tell” label placed on the top of
the shipment. This label is located at the top of the
hood, and has two reservoirs of blue glitter, if that
glitter is anywhere in the upper reservoir where the
blue arrow is pointing, this needs to be noted on the
BOL. This could mean that the shipment was tipped
over during transit. (See Figure 1.)
3. After inspecting shipment, remove the plastic wrap.
4. After removing wrap, cut the two straps on the
bottom. (See Figure 2.)
5. Using your 7/16 Socket wrench, remove the three
nuts located underneath the bottom platform. (See Figure 3.) repeat this on both the front and back
steel plates.
6. Once you have removed the nuts, slowly and gently
to avoid scratching the powder coated finish, remove
the steel plates. After removing front and back steel
plates your Pulse-Bac® should be ready to be removed from the pallet.
7. After removing your new PB-2150 or PB 2050 keep
and save the pallet and steel plates for return if
needed in the future for servicing.

Specifications Continued:
The PB-2050 and PB-2150 are equipped with
CDCLarue™ exclusive Tank Capacity Sensor
(TCS). The TCS™ is located in the upper collection
tank. TCS keeps the operator from over filling the
upper collection tank and extends the life of the
filters and motor on both models.
The TCS feature lowers the possibility of dust
accumulating and facing the filters over a period of
time due to the operator allowing the tank to be
overfilled. In addition the TCS will prevent the lower
dust collection tank from becoming overfilled,
eliminating another source of airborne dust
caused from overfilled collection tanks and spills.
TSC also helps to ensure that the lower tank or bag
when filled will not weigh more than forty pounds.

EXCLUSIVE TCS SYSTEM
(TANK CAPACITY SENSOR)
The PB-2050 and PB-2150 dust collectors
are equipped with CDCLarue exclusive Tank
Capacity Sensor (TCS ). The TCS™ system
is designed to prevent the vacuum from
over filling the upper collection chamber;
thereby reducing the risk of damage to the
filters and vacuum motor components.
Warning:
After signaling to the operator with a visual and audible alarm, the TCS system will
automatically turn the vacuum motor off, the vacuum motor can restart automatically
when the dust collectors TCS system is cleared of debris. This restart can cause the
operator to be surprised, possibly causing the operator to be startled and possibly injuring him or herself. Turning the dust collector’s power switch to the off position will
silence the audible alarm and extinguish the visual alarm, and ensure that the vacuum
motor will not restart until the power switch is returned to the on position.
1. The dust collector front bezel is equipped with a Red Light Emitting Diode (LED) indicator along
with an auditable alarm. These two components when lit or sounded notifies the operator that the
TCS sensor has detected a full tank and will turn the dust collector’s vacuum motor off if not emptied
in a timely manner.
2. Once the TCS system has turned the vacuum motor off, the vacuum motor will not restart unless the
tank is emptied or the sensor is cleared. Always check to see if the power switch is illuminated, if
illuminated this indicates that the sensor has the vacuum motor turned off and the PB-2050 or PB2150 is operating properly.
3. The audible alarm will continue to sound off until the sensor is cleared or the dust collector’s power
switch is turned to the off position.
Warning:
Dumping debris when using the Bagger:
When using the PB-2050 or PB-2150 with the bagging attachment, the operator must
insure that the butterfly dump valve is completely closed and sealed anytime the unit is
in operation. If the dump valve is left open or not sealed shut it will reduce the pressure
inside the upper collection tank. The operator can still dump the upper tank into the
bag while continuing to operate the unit in a normal manner as long as the valve is
closed once the main tank has been emptied. Do not leave the butterfly dump valve
open after dumping debris, close it immediately to maintain peak performance.

Page 11
Emptying the dust collector’s removable collection tank:
The PB–2050 and PB-2150 utilizes a unique butterfly valve that separates the upper
tank from the lower 8 gal. removable tank or bag. The valve can be opened and closed
with the dust valve handle shown in (figure 1.).
The butterfly valve allows the PB-2050 and PB-2150 to collect dust and debris in the
upper collection chamber without it falling into the lower removable tank. Once the upper tank is filled, open the valve and dump the debris into the bottom 8 gal. removable
tank or bag, then close and seal the valve. Now the removable tank or bag can be removed and the dust discarded while the machine is still in operation. You do not have
to turn off or stop production when empting and discarding dust and debris.
Collecting dust in the eight (8) gal. removable Tank:
1. Pull latches upward to loosen them from drum
attachment, do not totally unlatch the 8 gal.
tank from the drum attachment at this time.
2. Turn the dust valve handle to the “OPEN”
position and hold it in that position to
allow the dust to fall and settle in the
bottom of the 8 gal. removable tank or bag.
3. Turn the dust valve handle to the “Close”
position to close the valve.
.
4. Turn the knobs on base platform counter
clockwise to loosen, then pull them
to the right, now fully unlatch the two
latches on the tank from the drum attachment.
The tank should now be released from the
cart, roll the tank off the platform to
unload and discard debris.
5. After unloading the tank, place a new bag in
the tank (optional) and roll the cart back onto
the platform, use the guide wheel bracket so
that the latches on the side of the tank align
with the two latch holes on the drum attachment, then latch the tank.
6. Move the knobs over to the right so that they
align to the slots on the tank and then tighten
the knobs to secure the tank to the cart and
platform.

Unloading the Polyethylene Bag from the Collection Tank:
The eight (8) gallon tank has the option of using a six (6) mil. polyethylene bag to
collect dust and debris. This option requires the use of a polyethylene bag and a
nylon liner. The bag fits down inside the liner, and the liner fits down inside the tank
to facilitate easy removal of the dust and debris collected in the bag. After filling the
bag, remove the dust filled bag and install a new bag inside the tank, place the bag
inside the tank so that the bottom of the bag touches the bottom of the tank and
then fold the remaining top part of the polyethylene bag over the rim of the
collection tank as shown in the figure 2..
This procedure can be accomplished while the vacuum continues to operate and
collect dust in the upper chamber, an exclusive feature in both the PB-2050 and
PB-2150 CDCLarue dust collectors. The PB-2050 and PB-2150 are equipped with
CDCLarue exclusive Tank Capacity Sensor (TCS™) which will keep the upper tank
from over filling while the operator empties the lower removable tank to dispose of
the dust and debris collected inside the tank or bag.

CDCLarue 5 / 3 Channel Timer
PCB Revision D
Functional Description
Overview:
The 5/3 Channel Timer circuit design supports several different operating modes –
each of these modes are described in subsequent sections. At the heart of the design
is a microcontroller which handles all of the processing. Upon initial power-up, the microcontroller reads the settings for the Duration & Cycle Adjust Timers and determines
if board supports 3 or 5 channels. Once this information is determine, the Cycle Timer
begins its countdown, once it expires, Solenoid #1 is activated and the Duration Timer
begins its countdown. Upon expiration of the Duration Timer, Solenoid #1 is deactivated. Prior to activating the next Solenoid, the microcontroller inserts a 5 second
pause to allow the pressure in the tank to fully recover. Solenoid #2 is then activated
for specified duration, followed by another 5 second recovery period. This sequence
repeats itself until the last Solenoid (either #3 or #5) has been activated, which completes the cycle. The Cycle Timer is then reloaded and the countdown begins once
again.
Fixed vs. Variable Duration:
The ON duration of the Solenoids is either Fixed or Variable depending on the selected
operating mode. The operating mode is determined by the R16. When R16 is installed, the unit operates in Variable Duration Mode, which has a range of 0.1 to 1 seconds (in 5 millisecond steps). When R16 is removed, the Duration is fixed.
Cycle Duration:
The Cycle Duration has a range from 5 to 105 Seconds (in 200 millisecond steps).
The actual time is determined by a potentiometer setting on the board.
3ch vs. 5ch Selection:
R14 determines whether the unit operates in 3ch or 5ch Mode. When R14 is installed,
the unit operates in 5ch mode. When R14 is removed, the unit operates in 3ch mode.
110V vs. 220V Selection:
Resistors R110A & B and R220 configure whether the unit operates with 110V or 220V
input. For 110V operation, R110A & R110B should be installed (R220 must not be installed). For 220V operation, R220 should be installed (R110A & R110B must not be
installed). These appropriate resistor configuration must be in the appropriate position
prior to power the board.
12Vdc Auxiliary Output:
The Auxiliary 12Vdc output will provide approximately 200ma@12Vdc.
Sensor Support Circuit:
The 12Vdc Auxiliary Output above may be used to power an external (sensor) circuit,
which may in turn drive an on-board relay circuit. The terminal like labeled “SOUT”,
may be connect to the sensor’s output – this is actually an input (0 to 12Vdc), which is
active high (input voltage from 3 to 12Vdc). The state of this input drives an output,
RLY, which is a low side relay driver. This output can sink up to 200ma of current at
12Vdc.
With regular use the dust collector will at some point require repair of critical components from time to
time. This section of your manual will provide information for a qualified technician to make repairs to the
dust collector when required. Most repairs to the dust collector can be made at your facility if the technician making the repairs is trained in electrical and mechanical theory. If you are not qualified to repair
the dust collector you can contact CDCLarue™ customer services department and have the unit returned to CDCLarue or one of CDCLarue authorized service centers for repair. If you or someone you
know are qualified and need additional assistance in the repair of the dust collector, you can contact
CDCLarue service department and a qualified technician will help you to complete the repair.
CDCLarue recommends that any repairs made to the valve systems in your dust collector either be
made by CDCLarue or a technician that is qualified in the theory and repair of electro mechanical equipment.
Danger:
Attempting to repair any electro-mechanical equipment without proper knowledge of the theory
of electricity and mechanics can be detrimental to your health and could cause death or serious
injuries. You should not attempt any of the following repairs without being qualified in electrical
and mechanical repair theory.
If you or someone you have retained plan to make repairs on your dust collector you will need at
minimum the following tools and test equipment;
Volt ohm meter, digital or analog, Phillips screw driver #4 & #3, needle nose pliers,
5/16 “ nut driver, 3/8” end wrench, and 1/8” X 2” slot screwdriver.

1. Before replacing any or all of the solenoids, you must first determine which if any solenoid is
defective. You can determine if a solenoid is defective as follows;
2. Disconnect the dust collector from the electrical power source.
3. Loosen the hood cover by removing the four 10-32 X 3/4” Hex bolts holding it to
the base plate. (See Figure # 1) on page # 13.
4. Lift the hood and disconnect the wiring to the power switch, CCS alarm and alarm LED by
disconnecting the Molex connectors which connects the wiring between the main frame and
hood of the dust collector, before removing the hood.
5. Locate the printed circuit board in the units electrical assembly. Turn to page #16
for a depiction of the wiring block diagram for the solenoids. (Block Diagram) on
page 16.
6 You will need to use your volt ohm meter to determine which if any of the solenoids
is defective. Set your VOM to ohms using a scale of 200 ohms or less. Be sure to
zero your meter before taking your readings.
7. Turn to page 16 of this manual for the location of these test points on the printed circuit
board.
8. Connect your VOM negative test lead to the common point on the solenoid connection block TB1
on the printed circuit board marked ( SC ) or solenoid common. One by one place your positive
lead on each solenoid connection 1 thru 5 or 1 thru 3 for the for the model PB-2050. Each solenoid
should read approximately 84 ohms if the solenoid is good. Solenoids reading “infinity” is a signal
that the solenoid is open and will require replacing.
9. If you have a bad solenoid, you will need to remove the motor, electrical assembly and exhaust
plenum to gain access to the solenoids. You can determine which solenoid to replace by noting
the color of the wire when taking readings from the solenoid connection block. TB 1 on the PCB.
You will need to remove the solenoid plenum housing to gain access to the defective solenoid.
Remove the four (4) 5/16” flange nuts holding the housing to the main base plate,
10. Once you determine which solenoid to replace, disconnect the solenoid from the valve stem by
removing the retaining clip on the retaining pin then remove the retaining pin to release the solenoid
plunger from the valve stem. Do not use the old solenoid plunger or remove the valve to replace the
bad solenoid.
11. Remove the solenoid control wires by removing the quick connect connectors and remove the four
Phillips screws holding the solenoid to the solenoid mounting plate by using a small #4 Phillips
screw driver.
12. Replace the bad solenoid by reversing the above directions used to remove the solenoid.
13, When installing the new solenoid make sure you use lock tight on the Phillips screws
holding the solenoid to the solenoid mounting plate. If you do not lock tight the screws
holding the Solenoid to the solenoid mounting plate they may come loose and go through
the motor fan causing irreversible damage.
