Improper operation of dust collectors and/or dust control systems may contribute to conditions in a work area or
facility which could result in severe personal injury, and product or property damage. All dust collection equipment
should be used only for its intended purpose and should be properly selected and sized for its intended use.
Process owners have important responsibilities relating to identifying and addressing potential hazards in their
processes. When the potential for handling combustible dust exists within a process the process owner should
include combustion hazards in their risk management activities and should comply with applicable codes and
standards related to combustible dust.
Electrical installation must be performed by a qualied electrician.
This equipment is not designed to support site ducts, piping, or electrical services. All ducts, piping, or electrical
services must be adequately supported to prevent injury and/or property damage.
Site selection must account for wind, seismic zone, and other load conditions.
Equipment may reach peak sound pressure levels above 80 dB (A). Noise levels should be considered when
selecting collector location.
Most dusts present safety and health hazards that require precautions. Wear eye, respiratory, head and other
protection equipment suitable for the type of dust.
Some components may be heavier than they appear. Use appropriate lifting methods to avoid personal injury and/or
property damage.

Combustible Dust Hazards
Among other considerations, the current NFPA standards require owners whose processes involve potentially combustible
materials to have a current Dust Hazard Analysis, which can serve as the foundation for their process hazard mitigation strategy.
Mitigation may include but is not limited to:
• Prevention of all ignition sources from entering any dust collection equipment.
• Selection and implementation of re and explosion mitigation, suppression, and isolation strategies appropriate for the
risks in their process.
• Development and use of work practices to maintain safe operating conditions, and to ensure combustible dust does not
accumulate within their plant or process equipment.
Donaldson designs, manufactures, and sells industrial air ltration products for a wide variety of applications. Some applications
may include processes or materials with inherent re and explosion hazards. Donaldson is neither an expert nor a certied
consultant in re, spark, or explosion detection, suppression, or control. Donaldson does not provide engineering consulting
services related to process or dust hazard analyses, or code and standard compliance. Complying with applicable codes and
standards and managing the risks associated with the process or materials remains the responsibility of the process owner/
operator. Donaldson may provide referrals to consultants, suppliers of equipment or services related to the detection and/
or mitigation of sparks, res and/or explosions, but Donaldson does not assume responsibility for any such referrals, nor does
Donaldson assume any liability for the tness of a mitigation strategy or product for a particular installation or application. The
process owner’s nal selection of dust collectors and risk mitigation strategies should be based on the outcome of a Dust Hazard /
Process Hazard Analysis performed by the process owner. Although early engagement of a dust collector supplier provides helpful
insights on the availability and features of various products, process owners should consult with a combustible dust expert and/or a
process safety expert before making actual product and mitigation strategy selections.
Donaldson recommends that all industrial air ltration system designs be reviewed and approved by an expert consultant who is
responsible for the integrity of the system design and compliance with applicable codes and standards. It is the process owner’s
responsibility to understand the risks in their process and mitigate those risks in accordance with all applicable laws, regulations
and standards, including those published by the NFPA. Donaldson also recommends that proper maintenance and housekeeping
procedures and work practices be evaluated, developed, and followed to maintain any industrial air ltration products in safe
operating condition.
Many factors beyond the control of Donaldson can affect the use and performance of Donaldson products in a particular
application, including the conditions under which the product is used. Since these factors are uniquely within the user’s knowledge
and control, it is essential the user evaluate the Donaldson products to determine whether the product is t for the particular
purpose and suitable for the user’s application. All products, product specications, and data (airow, capacity, dimensions, or
availability) are subject to change without notice, and may vary by region or country.

The Delta P Controller monitors the differential pressure between the clean-air and dirty-air plenums, providing a visual display
of the lter condition. When combined with a pulse timer, it manages the pressure drop by turning the cleaning mechanism On
and Off at the chosen limits. There are three (3) set points: High Pressure On, Low Pressure Off, and Alarm. The rst two, High
Pressure On and Low Pressure Off, control the lter cleaning system. The third, Alarm, provides a relay output to activate an
external alarm supplied by others.
2 Product Description
3 Operation
Normal
The Delta P Controller monitors the pressure in the clean-air and dirty-air air plenums while the collector is running. The fan blower
draws air through the lters, creating a pressure drop. The Delta P Controller measures the pressure drop and provides a visual
display in inches water gauge or metric (SI) units of daPa.
Filter Cleaning
When the pressure drop across the lters exceeds the High Setpoint, the controller closes an output relay allowing a timer to
trigger the cleaning valves sequentially. When the pressure drop has decreased to the Low Setpoint, the relay opens and the
cleaning cycle stops. This sequence continues as long as the collector is in use, maintaining the pressure drop within a narrow
range.
Alarm
The Alarm setpoint is set to a higher setting than the High Pressure On setpoint used to start the lter cleaning cycle. It indicates
situations when the cleaning system cannot reduce the pressure drop due to cleaning system failure, lack of compressed air, or the
end of the lter’s useful life. There is a time delay prior to setting the Alarm to prevent nuisance trips. The Delta P Controller also
provides an input connection for a remote alarm reset.

Electrical installation, service, or maintenance work must be performed by a qualied electrician and comply with all
applicable national and local codes.
This equipment may start or stop unexpectedly from a remote location.
Turn power off and lock out all power before performing service or maintenance work.
The appropriate wiring schematic and electrical rating must be used. See collector’s rating plate for required voltage.
Do not install in classied hazardous atmospheres without an enclosure rated for the application.
Electrical Wiring
The Delta P control is factory set for 115-V. To operate at 230-V, the jumper settings on the printed circuit
board must be changed. See Optional Settings.
1. Choose a location near the collector that permits access to the keypad for adjustments and observation of the pressure drop.
If possible, mount the control indoors.
2. Mount the control enclosure using four self-drilling, self-tapping screws.
Use vibration isolators in high vibration areas.
3. Install conduit between the control’s enclosure, the solid-state timer, and the solenoid valve enclosure on the collector.
4. Using the wiring diagram provided with the control, make the wiring connections to the Delta P control, the solid-state timer,
and the solenoid valves. Make the required connections to the motor starter’s low-voltage terminals.
Use proper grounding and handling procedures to prevent permanent damage to this device. Handle the
printed circuit board by the edges only. Do not touch the socketed E2PROM pins.
5. Wire the auxiliary alarm circuit, if desired. This relay activates the ALARM light on the control panel and the alarm relay if the
pressure drop exceeds the alarm setpoint. The auxiliary relay can be used to activate visual or audible alarms provided by
others.
6. Thirty-ve feet of plastic tubing is supplied with the control and must be cut in two sections. Connect one section of tubing from
the control enclosure’s high-pressure port to the pressure tap on the dirty-air plenum. Connect the remaining section of tubing
from the control enclosure’s low-pressure port to the pressure tap on the clean-air plenum. Additional tubing can be ordered
from your representative.
7. Place the program wire on the solid-state timer board pin to match the number of solenoid-valve connections used.
8. Apply power to the control. Set the high- and low-pressure setpoints to start and stop the cleaning process. Set the alarm
setpoint to activate the alarm display. See Control Calibration.

Delta P Control Calibration
The only user calibration is the zero adjustment of the display. Due to slight changes in electronic components over time, or
pressure differentials within the plant environment, the display may read something other than 0.0 while at rest. Use the following
procedure to recalibrate the operating system.
1. Turn power to the Delta P Control ON for a minimum of 30-minutes to stabilize the operating temperature.
2. Disconnect the pressure tubing, either leaving it to atmosphere or connecting the two barbed ttings together with a short
length of tubing.
3. Turn power to the control OFF.
4. Press and hold the LOW SET, HIGH SET, and ALARM SET keys while turning power to the control back ON. Continue holding
the keys as the control goes through its power-up sequence. The number 8 is displayed in each digit, and then the display
reads 0.0.
5. Release the three keys. The new calibration is automatically stored in memory.
6. Connect one section of tubing from the control enclosure’s high-pressure port to the pressure tap on the dirty-air plenum.
Connect the remaining section of tubing from the control enclosure’s low-pressure port to the pressure tap on the clean-air
plenum.

Optional Settings
230-V Power Supply
To operate at 230-V, remove two jumpers labeled W1 and W3. Reinsert one of the jumpers in position W2.
Change from English to Metric (SI) Units
On the J1 jumper block located above the PROG DISABLE terminals, move the jumper from the center and left pins 2 and 3, to the
center and right pins 1 and 2.
Disable Setpoint Adjustment
To restrict setpoint changes, install a jumper wire across the PROG DISABLE terminals on Terminal Block 2, TB2. The current
settings can be displayed, but no changes can be made until the jumper is removed. Interrupting the jumper with a key-operated,
normally-closed switch installed in the enclosure door provides temporary access to the setting functions without opening the door.
External Alarm Reset
Wire the ARM RESET terminals on Terminal Block 2, TB2, to a key-operated, normally-open switch. Closing the switch turns the
alarm OFF. If alarm conditions still exist, the alarm relay reactivates in 10 seconds.
Alarm Disable
Remove the jumper on Jumper Block J5 located on the lower-right quadrant of the circuit board, from the ALARM mode position.
1. Reinstall the jumper in the SLAVE mode position to operate the AUXILIARY relay in parallel with the HI/LO CONTROL relay.
2. The AUXILIARY relay will not function if no jumper is installed.
Note: Disabling the alarm relay reduces the alarm function to visual display only.
Analog Output (TB4, Terminals 13 & 14)
Terminals 13 & 14 on Terminal Block 4, TB4, in the upper-left quadrant of the circuit board, provide a 4 to 20 mA output
proportional to the 0-to-maximum span of the pressure sensor. This circuit requires a 500 ohm maximum load.
