Donaldson Cartridge Dust Collector DWS 6-4

Filter Removal and Installation

Use proper safety and protective equipment when removing contaminants and filters.

Dirty filters may be heavier than they appear.

Use care when removing filters to avoid personal injury.

Note: Remove filter cartridges by opening the top and bottom doors. Start with the top filters first. Optional plastic filter bags are offered for filter and dustpan dust removal for cleanliness.

1. Turn the knob counterclockwise until it is loose. Remove the knob and access cover.

2. Remove the filter cartridge from the yoke.

Do not install in classified hazardous atmospheres without an enclosure rated for the application.

Install chamber silencer after the motors are wired and rotation checked.

Install the silencer to the top of the power module using the hardware supplied.;

Electrical work must be performed by a qualified electrician and comply with all applicable national and local codes.

IEC Control Panel with Programmable Logic Control

This control panel contains a safety disconnect switch, blower motor control, pulse control functions, and a Magnehelic gauge. The Programmable Logic Control, PLC, provides features such as sequential start-up, staggered aftershift cleaning, and troubleshooting capabilities.

1. This control panel includes magnetic starters with a low-voltage control circuit.

2. The blower motor ON/OFF buttons are located on the control panel cover. A red blower motor RUNNING light is also provided.

3. Sequential start-up is provided for all DWS 4- and DWS 6-2, 3, and 4 modules. This allows a delay between starting each blower motor and reduces undesirable overload current at start-up.

4. The control panel has troubleshooting capabilities. If a blower motor shuts down due to a failure, such as an overload, the panel will flash the red RUNNING light quickly. The two amber lights, CLEANING and AFTERSHIFT CLEANING, will also flash indicating which circuit tripped the alarm.

For example: The overload on motor protector #3 is tripped. The red RUNNING light will flash quickly and the two amber lights, CLEANING and AFTERSHIFT CLEANING, will flash three times, then pause and repeat. This indicates that motor protector #3 has been tripped. The lights will continue to flash until the alarm is serviced.

5. Thermal overload relays and circuit breakers are provided for the motor circuit and fuses for the low voltage circuit. Standard voltages available are 208/230/460/575/60 Hz/3 phase.
