Power On/Off Switch – The power switch is used to turn the Controller On and Off. The power down sequence is to
turn off the user interface first via the touchscreen and then hard power down via controller switch.
Power Input – The power cord plugs into the Controller and a conventional 100-240 VAC receptacle, 1A at 50-60
Hz(as indicated on the label located on the back of the Controller) and provides power to the Controller. Fuse rating
is 250 V, 4A Slow Blow, Type T
Gas Input – Standard, hospital supplied tubing connects the regulator of the compressed gas cylinder to the
Controller allowing for gas to be supplied to the Turbine.
Potential equalization terminal - For the purpose of testing the grounding of the controller. Note: remainder of roll
stand may not be grounded.

Roller Pump – Pumps saline from the 1000 ml saline bag through the Sheath and around the Shaft.
Foot Pedal
Foot Pedal Housing – The basket below the Controller houses the Foot Pedal and power cord for storage
Foot Pedal
The Foot Pedal comes pre-connected to the Controller. When the pump is on and a speed setting selected,
depressing the electrical Foot Pedal once causes saline to flow at the high pump speed. Depressing the Foot Pedal
again (within five seconds) opens the compressed gas line and starts the turbine, which results in Shaft/Crown
rotation. Releasing the Foot Pedal closes the compressed gas line and stops Shaft/Crown rotation. The pump speed
automatically resets to low pump speed within 7 seconds after release of the foot pedal.
Compressed Gas Cylinder and Regulator
Additional equipment needed to operate the OAS includes a compressed gas cylinder and cylinder pressure regulator
or a hard plumbed compressed air line set between 85-100 psi.
Compresses Gas System
A compressed gas system must contain air or nitrogen. A cylinder capacity of at least 80 standard cubic feet (2250
liter) is recommended and will provide approximately 20 minutes of service with the OAS running at full speed.
Larger cylinders may be used. A fully charged spare cylinder should always be available.
Cylinder pressure regulator – The cylinder pressure regulator must be capable of delivering at least 5 scfm (140
liter/min) at 85-100 psi (5.8-6.9 bar). A relieving type cylinder pressure regulator is preferred. The regulator’s
cylinder filling capability should be compatible with the gas cylinder being used.
Hospital Air System
A hospital compressed air or nitrogen system can be used in place of a gas cylinder and regulator.
1. The compressed gas must be air or nitrogen.
2. The gas must be clean, dry, and oil free.
3. The gas pressure must be 80-100 psi (5.8-6.9 bar, 551.6-689.6 kPa) at the inlet to the Controller.
4. The system must be capable of supplying gas at a rate of 5 scfm (140 liter/min).
