Faulty water control valve. Water toggle is in O FF position. No water in clean water bottle. Faulty water flush toggle valve. Purge water lines. If unit was purged, replace water control valve. Place toggle in O N position. Fill clean water bottle. If water is present at valve, but not flowing, replace valve. S ymptom Possible Cause(s) Handpiece Solution No drive air. No fiber optic light at handpiece. Drive air flow adjustments pinch valves are closed. on Faulty handpiece holder valve. Faulty foot control. Pinched or restricted tubing. Power transformer is not plugged in. Internal wires in control head and post-mounted console are not connected. No signal air to fiber optic lamp control. Faulty transformer. Faulty fiber optic control. Faulty bulb. No signal air to receptacles in the USC. Using a screw driver, turn adjustment screw counterclockwise to adjust drive air pressure. Set to manufacturer's recommended pressure. If pinch valve does not release with handpiece out of holder and tubing to holder is not restricted, replace hanger valve. Depress foot control. If no air is present, repair or replace foot control. Straighten or replace tubing. P lug transformer into designated receptacle in USC. Check connections in control head and post-mounted console. Check for pinched or restricted tubing. Check output for 22-23 VAC. Fiber optic controls have a calibration range of 2.5 to 6.0 VDC. Check for proper voltage according to the handpiece manufacturer's recommendations. Replace bulb. Check for pinched or restricted tubing. 36 Installation, Operation and Care Manual
Section VII User Service Information Handpiece (continued) S ymptom Possible Cause(s) Solution No coolant water at any handpiece Water dribbles from handpiece while in holder. Water dribbles from handpiece after foot control is released. No coolant air to handpiece. Coolant water adjustment valves closed. Water toggle on foot control is in the O FF position. Water toggle on clean water system is in O FF position. Slide clamp is in clamped position. Water bottle empty. Pressure too low on clean water system. Pinched or restricted tubing. Faulty handpiece holder. Pinched or restricted tubing to holder. Pinch valve leaking. Low air pressure. Low air pressure. diaphragm is Faulty water control valve. Faulty water relay in foot control. Pinched or restricted tubing from foot control. Slide clamp is in clamped position. Pinched or restricted tubing. Turn valve counterclockwise to open valve. Flip Flip toggle to the right for the toggle to the O N position. O N position. Slide clamp so it moves freely on tubing. Fill water bottle. Verify clean water system pressure adjust accordingly. Straighten or replace tubing. Repair or replace holder. Straighten or replace tubing. Replace diaphragm. gauge reads 40 PSI and Ensure air regulator gauge in floor box reads 80 PSI. Ensure air regulator gauge in floor box reads 80 PSI. Depress foot control then release. Remove black tubing from water control valve. If dribble continues, replace valve. Turn unit off. Open foot control and inspect water relay block. If piston is not damaged and is moving freely, stretch the spring. Reassemble and retry foot control. Straighten or replace tubing. Reposition slide clamp so it moves freely on tubing. Straighten or replace tubing. axcs Magellan CMU 37
Section VII User Service Information axcs Magellan CMU Arm System S ymptom Possible Cause(s) Solution Horizontal arms drift left or right. Unit head is not level from front to back. Adjustable arm does not hold position. Adjustable arm will not move. Unit Pivot is not properly leveled. is not properly adjusted. Improper adjustment. Faulty brake switch. Faulty lock arm actuator. Faulty brake switch. No air to brake switch. Faulty arm lock actuator. Verify unit seated. is level. Also, verify arms are properly Remove adjustable arm cover and adjust nut at pivot. With nothing on delivery head, adjust the nut on the spring so unit stays in place. Remove adjustable arm cover to see if locking arms are in place. If they are stuck in the up position, check brake switch. When brake switch is activated, ensure lock arm actuator strikes lock arms. Also, ensure lock arm actuator is not stuck in actuate position. When brake switch is depressed, ensure air is reaching lock arm actuator. Ensure unit master toggle is in O n postion. If air is reaching actuator, but not extending, replace lock arm actuator. S ymptom Possible Cause(s) Water Heater Solution No warm water, cold water only. Extension cord heater. disconnected from water Water temperature is set too low. Pinched or restricted signal air tubing (1/8" yellow) to electrical receptacle in post-mounted console. Unit's extension cord is not connected to power supply. Faulty water heater. Ensure extension cord in post-mounted console is plugged into water heater. Turn adjustment screw on water heater clockwise to increase temperature. Straighten or replace tubing. Verify power supply and proper extension cord connection inside USC. Replace water heater. 38 Installation, Operation and Care Manual
