Place appropriate safety signage on all access doors where CLEAN SWEEP are installed. DO NOT inspect CLEAN SWEEP nozzles when operating. Always shut off and tag out CLEAN SWEEP prior to entering or inspecting chutes or bins where CLEAN SWEEP are installed.
- Page 4 THEORY OF OPERATION The Pneumatic Accumulation Control System (CLEAN SWEEP) works on the principle that compressed air can be utilized to remove buildups of wet, sticky material from the walls of bulk solids handling system chutes, bins and hoppers. Compressed air (80 to 100 psig) has been proven to exert enough energy to remove large accumulations of build up on chute walls.
- Page 5 INSTALLATION If your CLEAN SWEEP System will NOT be installed by Benetech personnel, or you have chosen to expand the CLEAN SWEEP System yourself, installing/expanding your CLEAN SWEEP System can be completed per the following instructions: CLEAN SWEEP Installation 1. Determining where to locate CLEAN SWEEP nozzles: CLEAN SWEEP nozzles should be located at the area where material first starts to build up.

Page 7: Operations
OPERATIONS OVERVIEW The system is designed to maintain material flow through hoppers, bins, or chutes using a sequential timing device to alternately fire each CLEAN SWEEP nozzle. The system can be interlocked with a “run permissive” to ensure that the system will only operate during times when material is present. -
Page 8: Adjustments
ADJUSTMENTS The digital timer boards located inside the control panel activate the CLEAN SWEEP nozzles in a preset sequence and interval to insure even clearing of material. The firing order is usually from the discharge (lowest unit) of the chute or hopper to the top. - Page 9 The first four (4) adjustments are made on the timer board. Press the select button on the timer board. Then press the adjust button to change the value. The last adjustments are made on the timer relay. Step 1: Press select button on timer board. An LED will light next to “ON Time”.
- Page 10 Step 6: Adjust third (lower) thumbwheel on the timer relay to 0-60 seconds for length of active time when in “TIMED” mode. (4) Adjust the fourth timer to three to four minutes. This is the amount of time the system will be at rest between cycles Page 10...
