Service/Usage Information Factory Default Routine
Factory Default Routine
When a new circuit board is installed in the chair, the circuit board
needs to run the factory default routine to learn the range of motion of
the chair.
The routine:
• sets the base and back upper limits
• calculates new presets based on actual range of motion of the chair
• verifies that the potentiometers work
To start the factory default routine, place the “spare” jumper in the
factory default position on the P3 test points of the chair circuit board.
When running the factory default routine the chair:
1. Moves base down
2. Moves base up
3. Moves back down
4. Moves back up
5. Moves base and back to Position 0
6. Beeps three times
NOTE The jumper must remain in the factory default position
to complete the factory default routine. The status LEDs on the
standard and deluxe touchpads and the chair circuit board
double blink while the factory default routine is running and
after the routine is complete.

Service/Usage Information The Hydraulic System
The Hydraulic System
The hydraulic system deactivates automatically at the upper and lower
extremes of travel. The system is leak-free during transportation,
storage, and operation. The hydraulic system consists of:
• Hydraulic fluid reservoir
•Hydraulic cylinders
• Motor-driven hydraulic pump with solenoids
Hydraulic Fluid Reservoir
The hydraulic fluid reservoir is located in the lift arm of the chair under
the stop plate cover. You can see the fluid level in the reservoir through
the sides of the reservoir. A top fill cap allows you to add fluid. The
hydraulic system holds 40 ounces (2.5 pints [1.18 l]) of hydraulic fluid.
To fill the reservoir:
1. Place the chair in the full base and back up position.
2. Fill to the green Max line (see Figure 7).
CAUTION Do not over fill.
Figure 7 Hydraulic Fluid Reservoir

85.0816.00 Rev B 2007-04 21
Service/Usage Information The Hydraulic System
Hydraulic Cylinders
The hydraulic cylinders operate during the Base Up and Back Up
functions. Springs and gravity retract the piston during Base Down
and Back Down functions.
The chair seat travels vertically from a low point of 13.5" (343 mm) to a
high point of 31.5" (800 mm) above the floor (see Figure 8).
Motor-driven Hydraulic Pump
The hydraulic pump takes hydraulic fluid from the reservoir and
pressurizes it to extend the chair lift and tilt hydraulic cylinders for
back and base up functions. The bi-directional pump rotates one
direction for Base Up and the opposite direction for Back Up. The
solenoids mounted to the pump assembly gate hydraulic fluid from the
two cylinders. Depending on the chair Down function, the controller
selects which solenoid-actuated manifold valves are open or closed.
The 100-120 VAC pump and 220-240 VAC pump are equipped with an
automatic reset 110°C (230°F) thermal limiter. There are no serviceable
parts on the hydraulic pump other than the solenoids.
NOTE You can not adjust the speed of the chair.

Solenoids
Part No: 90.1070.00, 110 - 120 VAC
Part No: 90.1071.00, 220 - 240 VAC
How to Test Solenoids
A solenoid is entergized during Base Down and Back Down functions.
To check for a failed solenoid, test the solenoids using a volt/ohm
meter or magnetic pull test:
Magnetic pull
1. Hold a paper clip loosely in your hand.
2. Activate the solenoid by pressing Base Down or Back Down on the
footswitch or touchpad.
3. If there is a pull on the paper clip, the solenoid is being entergized.
Coil resistance
1. Disconnect the solenoid power at the 2-position connector.
2. Place on Ohm meter probe on each of the solenoid connector
terminals.
100 - 120 VAC = 177 Ohms ± 18 Ohms
220 - 240 VAC = 845 Ohms ± 85 Ohms
WARNING You must depressurize the base or back system
prior to removing the solenoid.
1. Depressurize base or back system,
2. Remove the failed solenoid coil
3. Replace with the operating solenoid coil.
4. Lower the chair base and back.
Figure 10 A-dec 511 Chair Solenoids

NOTE If the solenoid is hot, then the resistance reads higher.
NOTE When replacing a solenoid, wipe up any oil, and
replace existing O-rings on the solenoid base.
ELECTRICAL WARNING The solenoid coils are powered by line
voltage (100, 120, or 240 VAC). Failure to unplug the chair may
result in serious injury from electrical shock.

Potentiometer
The potentiometer and cable assembly is a simple, accurate unit, which eliminates position float. “Float” is a slight change or variation in the
pre-programmed positions. The chair uses the same potentiometer assembly for both lift and tilt requirements. If a potentiometer should fail, the
limp-along feature allows the operator to position the chair for one second intervals by pushing the manual control buttons on the
touchpad or footswitch.

Service/Usage Information Chair Stop Plate
Chair Stop Plate
The chair stop switch stops chair movement when you press the stop
plate. Should anything inadvertently become lodged under the chair,
press Base Up on the touchpad or footswitch to raise the chair so you
can remove the object. As long as you apply pressure to the stop plate,
the chair does not move down.
The stop plate has only one switch. The switch and all other parts snap
into place for easy removal or replacement. No tools are required.
WARNING Be sure to power off the chair and disconnect
it from its power source before replacing the stop switch.
CAUTION Cable tie the wires to the lift arm to prevent
kinking and pinching.

PROGRAMMING
The A-dec 500 touchpad centralizes treatment room controls into one
touch surface. Some touchpad buttons have indicators to alert you if
the operation is functioning. A-dec touchpads control multiple chair
and delivery system functions:
• Standard Touchpad—chair, light, cuspidor controls and auxiliary
equipment
• Deluxe Touchpad—chair, light, cuspidor, air/water coolant, electric
handpiece, scaler, multiple users and auxiliary equipment
This section provides programming information for all of the A-dec
500 modules as well as information related to servicing, maintenance,
and adjustments. For information on service parts, see the Genuine
A-dec Service Parts Catalog or contact A-dec customer service.

Tension Adjustment
If the front-mount arm drifts, adjust the front-mount tension. To adjust
the front mount tension, tighten or loosen the rotation bolt connecting
the front-mount arm to the front-mount casting. Turning the rotation
bolt right increases the tension on the arm and left decreases
the tension.
