4.1.4 If equipped, PCF models can be maneuvered through the use of the fork pocket option, located on the bottom of the feeder. Only proper lifting equipment should be used to move PCF feeders. If the fork pocket option is not present, lift at your own discretion.
5.0 OPERATION
5.1 As was presented in the introduction section, typical precoating rates for cartridge filters vary from 0.5 to 2.5 lbs/filter, but rates can vary by application. The 2 major variables, that can be adjusted to deliver a rate of precoat material, satisfactory to your needs, are the pulse control board and the compressed air pressure. When adjusting the pulse control timer, “Time On” is for the length of time the valve is open. This can be set from 50 mSEC to 500 mSEC. The factory setting is 100 mSEC. “Time OFF” is the time delay between pulses. This can be set from 1 SEC to 180SEC. The factory setting is 60 SEC. The timer board has 10 stations. The factory wires a pulse valve to every second station, thereby increasing the time off to 2 SEC - 360 SEC. Your unit is factory set at approximately 100 mSEC for “Time ON” and 360 SEC for “Time OFF” (this cycle repeats until the pre-coat unit is turned off OR the blower is powered down, provided the contacts are connected appropriately). Additionally, the compressed air pressure going to the feeder can be adjusted, which could also have a significant impact on feeder rates. Typically, 60 PSI for the PCF-60, and 90 PSI for the PCF-150, is recommended. However, this value can be adjusted up or down depending on your choice of precoat material. NOTE: Excessive compressed air pressure will cause precoat material to escape the confines of the unit.
Each PCF series feeder comes with a “Constant Feed” feature. This feature is used when new filters are installed in the dust collector and is located on top of the feeder, right behind the access door. During normal operation, this valve should remain OFF. Once new filters have been installed, this valve can be turned ON, creating a constant feed of precoat
