PASER®CF900
ABRASIVE DELIVERY SYSTEM

PASER CF900 Abrasive Delivery System
Intended use
The PASER CF900 Abrasive Delivery System (ADS) is designed for the continuous
transport of abrasive materials. A programmable logic controller (PLC) constantly
monitors the level of abrasive, and a control cabinet provides visual and audio feedback.
Safety
Operating errors or misuse may endanger the health of the operator, the ADS, other
valuable property, and can prevent the efficient functioning of the equipment.
Ensure that the machine workspace is clean and clear.
Modification of products
For safety reasons, do not do independent refits, conversions, or changes to the machine.
Strictly adhere to operating, maintenance, and installation conditions in this manual.

Personal Protective Equipment (PPE)
All maintenance and operating personnel shall practice and promote safety at all times to
avoid potential injury and unnecessary downtime.
Any personnel in proximity of the equipment must wear safety glasses
with side shields to prevent eye injuries caused by pressurized
abrasive leaking from the silo or hose.
Maintenance personnel must wear safety gloves when cleaning the
machine to prevent abrasive particles from penetrating any existing
wounds or skin abrasions.
Personnel must wear dust masks or respirators when loading abrasive
materials into the silo to prevent particle or dust inhalation.
Hearing protection is recommended.

Signal panel words
DANGER indicates a hazardous situation, which if not avoided, will
result in death or serious injury.
NOTICE indicates a non-hazardous situation, which if not avoided,
could result in property damage.
Lockout/Tagout
The lockout/tagout procedure protects personnel from injuries caused by the unexpected
energizing or startup of the ADS or the release of stored energy during service or
maintenance.
Do the lockout/tagout procedure before doing service or maintenance procedures.
WARNING! Failure to do the lockout/tagout procedure can result in
equipment damage or injury to personnel.
1. Stop the ADS by turning off the power switch, and then lock and tag the power
switch.
2. Turn off the air supply to the ADS, and then lock and tag the air source.

Transport the ADS
Contact Flow Technical Service if you are connecting the ADS to a different voltage power
supply in the new location.
CAUTION! Comply with your local regulations for moving equipment. Flow
recommends the presence of flaggers and spotters.
1. Empty the silo.
WARNING! The silo must be empty to transport the ADS. If you
leave abrasive in the silo, it can cause an unsafe high center of
gravity during transport.
2. Disconnect the electrical and pneumatic connections.
3. Use a forklift or pallet jack to lift the ADS. Place the forks under a pair of lower
beams on the frame (accessible from all four sides). Transport it to the final
operating location.
4. Place the ADS on a level and solid foundation.
5. Level the ADS with the leveling pads.
6. If required, use anchor bolts to attach the ADS to the floor.

Components
The abrasive material is loaded through the sieve and temporarily stored in the silo. You
can fill the silo without stopping the ADS. Abrasive moves from the silo through a pinch
valve, and then to the vessel. The abrasive flows through a hose to the cutting system.
Visual and audio signals provide operating condition and warning notices. The control
cabinet display shows status messages.
There are two low abrasive switches:
Silo low abrasive switch. When this switch does not sense abrasive, it signals the
PLC to start the flashing warning indicator and rhythmic audio signal. The display
panel shows the “Silo Empty” message.
Vessel low abrasive switch. When this switch does not sense abrasive, it signals
the PLC to start the continuous warning indicator and continuous audio signal.
The display panel shows the “Vessel Empty” message. If you are using FlowCUT™,
the program stops.

Control cabinet
The control cabinet uses alternating current (AC) from 100 to 240V at 50/60Hz, or 24V
direct current (DC). The internal control voltage is 24V DC.
The control cabinet contains the PLC, terminal strip, and warning indicators.
The PLC constantly monitors the operating conditions and sends control signals to the
solenoid valves, the warning indicator, and the audio signal.
